+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+            a screen saver and locker for the X window system
+                            by Jamie Zawinski
+
+                     http://www.jwz.org/xscreensaver/
+
+To build on Unix:
+
+  -  ./configure
+  -  make
+  -  make install
+
+The `configure' shell script will attempt to figure out which options are
+appropriate for your system, and will create config.h and the various
+Makefiles for you.  Run `configure --help' to see how to override these
+choices, or to specify things like the default installation directory.
+The file `INSTALL' gives a general overview of use of these sorts of
+configure scripts (those generated by the GNU autoconf system.)
+The most important hint is probably this:
+
+     ./configure --with-motif=/opt/Motif --with-xpm=/usr/local
+
+To build on VMS, see README.VMS.
+
+If you are upgrading, you might want to delete your ~/.xscreensaver file.
+If you don't, you might not see the new graphics modes.  If you are upgrading
+from version 2.* to version 3.*, definitely do delete your .xscreensaver file.
+
+If you think you've found a bug, please let me know!  No bug report is too
+small.  But first, please read the enclosed `README.debugging' file to find
+out what kind of information would be most helpful to include in your bug
+report.
+
+Getting Started:
+
+You can try out xscreensaver like so:
+
+       xscreensaver &
+       xscreensaver-command -demo
+
+After a few seconds, the screen should go black, and a dialog box should
+appear in the upper right corner.  This is "Demo Mode".
+
+Note: unlike `xlock', xscreensaver has a client-server model: the
+`xscreensaver' process is a daemon that runs in the background; it is
+controlled by the foreground `xscreensaver-command' program.
+
+xscreensaver has an extensive manual -- please read it!
+
+                              ============
+
+The xscreensaver daemon waits until the keyboard and mouse have been idle
+for a period, and then runs a graphics demo chosen at random.  The demo is
+terminated as soon as there is any mouse or keyboard activity (or, in
+locking mode, when the proper password is typed.)
+
+It is trivially easy to add new display modes to xscreensaver: any program
+which can be invoked in such a way that it draws on the root window of the
+screen can be used as a screensaver.  You just change a config file --
+there's no need to recompile or reinstall anything.
+
+                              ============
+
+Along with the xscreensaver daemon itself, this package also includes
+numerous graphics hacks for use as screensavers.  There is nothing magic
+about these: they are just programs that draw on the root window.
+
+More than 100 such programs are included.  For details, see the xscreensaver
+web page, or the enclosed manual pages.  There are also some helpful hints
+on customization in the xscreensaver app-defaults file (normally installed
+in /usr/lib/X11/app-defaults/XScreenSaver.)
+
+The latest version of xscreensaver is always available on the web at
+http://www.jwz.org/xscreensaver/.
+
+                              ============
+
+Changes since 3.15:   * New version of `shadebobs'.
+                      * Improved image selection in `webcollage', and sped it
+                        up slightly.
+                      * Made configure find the right version of perl.
+                      * Rewrote the CGI part of `webcollage'.
+                      * `make clean' was deleting some things it shouldn't.
+                      * Fixed a typo in the default programs list.
+Changes since 3.14:   * Added `webcollage' and `shadebobs' hacks.
+                      * Added a `-stdout' arg to `vidwhacker' so that it can
+                        be used in a pipeline.
+                      * Made `petri' use less memory.
+Changes since 3.13:   * Various improvements to the Gtk port.
+                      * Turned off PAM by default on Solaris, since PAM seems
+                        generally to be misconfigured out-of-the-box.
+                      * Made the `--without-gtk' configure option work.
+                      * Made configure check the Gtk version number, since it
+                        requires 1.2.
+                      * Fixed a bug in the code that attempted to prevent
+                        changes of screen resolution while the screen is
+                        locked.
+                      * Fixed a race condition in `xscreensaver-demo' that
+                        could cause an X error at startup.
+                      * Added `-transparent' option to `deluxe'.
+                      * Added `petri' hack.
+Changes since 3.12:   * Ported `xscreensaver-demo' to Gtk.
+                      * Made it possible to build Motif, Gtk, and Athena
+                        versions of `xscreensaver-demo' in the same directory
+                        without reconfiguring.
+                      * Made `xscreensaver-demo' chase symlinks before writing
+                        the .xscreensaver file, so that if .xscreensaver is
+                        itself a symlink, the underlying file will be replaced
+                        instead.
+                      * Some Makefile and configure tweaks for Solaris and
+                        FreeBSD.
+                      * Made it possible to set the fire color in `xflame'.
+                      * Made transparency work in TrueColor (for `goop' and
+                        `qix'.)
+                      * Fixed a multi-head bug introduced by the virtual
+                        viewports stuff.
+Changes since 3.11:   * Made it so that you can't scroll the screen while the
+                        lock dialog is up (with XFree86 virtual viewports.)
+                      * Fixed a bug in `flag' that caused bob's chin to get cut
+                        off after a few iterations.
+Changes since 3.10:   * Made `xjack' be black-on-white-ish, so that it looks
+                        less like a computer screen and more like the
+                        typewritten paper it's supposed to be.
+                      * New version of `pulsar'.
+                      * Fixed Solaris compilation problem in `phosphor'.
+                      * Made xscreensaver notice XFree86's virtual root window
+                        hack, so that if the X server's root window is larger
+                        than the monitor's displayable resolution, the screen
+                        saver will limit itself to the area that actually
+                        appears on the screen.
+                      * Made the xscreensaver daemon do a better job of
+                        picking the visual class that should be used for GL
+                        programs.  Less user intervention should be needed
+                        now: you can use the logical visual name `GL' instead
+                        of having to figure out by hand which one to use.
+                      * Oops, the visual was defaulting to "best" instead of
+                        "default", because the .xscreensaver file was not being
+                        loaded quite early enough.
+                      * Made configure figure out how to build icmp ping
+                        support into the `sonar' hack automatically.
+                      * Made warnings about not being able to read shadow
+                        passwords not be printed if compiled with PAM support.
+                      * Improved PAM startup diagnostics.
+                      * Worked around the Solaris PAM bug that was causing
+                        crashes there, so now PAM is turned on by default.
+                      * Made configure detect the number of arguments that
+                        pam_strerror() takes, since on Linux, this apparently
+                        changed between 2.0 and 2.2, sigh.
+                      * Made the /proc/interrupts kludge look for "PS/2 Mouse"
+                        as well as "keyboard".
+                      * Made xscreensaver notice when there has been a sudden
+                        large jump in wall-clock time, and if so, lock right
+                        away, instead of waiting for "lockTimeout" to expire
+                        first.  (Laptops need this for safer recovery from
+                        ``hibernation.'')
+                      * Added `-throttle' option to `xscreensaver-command'.
+Changes since 3.09:   * Added `phosphor', `xmatrix', and `pulsar' hacks.
+                      * Fixed a bug in the color allocator that sometimes
+                        caused `starfish' to fall back to monochrome.
+                      * Reduced the amount of code that runs before root
+                        privileges are disavowed: "normal" and "shadow"
+                        passwords now do some initialization as root, but the
+                        PAM and Kerberos authorization schemes will be
+                        initialized while running as "nobody".  Supposedly 
+                        this closes a potential security hole when using
+                        Kerberos.
+                      * Added some more sanity checking to configure.
+Changes since 3.08:   * Added `compass', `squiral', `xflame', `wander',
+                        `spotlight', and `critical' hacks.
+                      * Added some new modes to `decayscreen'.
+                      * Made `deluxe' work in monochrome.
+                      * Generalized usage of the Double-Buffer server extension
+                        in several hacks (`compass', `deluxe', `interference',
+                        `kumppa', and `moire2'.)
+                      * Fixed another visual-depth problem in `rd-bomb'.
+                      * The screen saver will now defer blanking if neither
+                        the keyboard nor the mouse could be grabbed.  Instead,
+                        it will just try again in a few minutes.  This fixes
+                        a bad interaction between xscreensaver and programs
+                        like VMware that hold the mouse and keyboard grabbed
+                        for a long time.
+                      * Added a new erase mode (expanding spiral.)
+Changes since 3.07:   * Fixed some bugs in my port of `t3d'.
+                      * Added `penetrate' and `deluxe' hacks.
+                      * When linking against Motif 2.x, also link against XPM.
+                      * Added support for using /proc/interrupts for idle
+                        detection on Linux.  Now xscreensaver shouldn't kick
+                        in when the user is active on a non-X virtual console.
+                      * Upgraded to autoconf 2.13.
+Changes since 3.06:   * Configure tweaks (sometimes -lXmu wasn't getting linked
+                        in properly; check for _Xsetlocale in -lXintl.)
+                      * Portability fixes for sonar.c.
+                      * Fixed a compilation problem when you have GL but don't
+                        have XPM.
+                      * Made configure notice when MesaGL requires -lpthread.
+                      * Made `flame' ignore SIGFPE (not sure if this is the
+                        right fix; it seems only to be needed on FreeBSD.)
+                      * Kludged `rd-bomb' work on visuals that are of depth 24
+                        but that *do not* support pixmaps of depth 32.
+                      * Fixed `halo' to work properly in TrueColor.
+                      * Changed `xscreensaver.spec' to install the hacks in
+                        /usr/X11R6/lib/xscreensaver/ by default, since that's
+                        where recent Red Hat distributions put them.
+                      * Added `t3d' hack.
+                      * Updated versions of `crystal', `hopalong', and `flow'
+                        from xlockmore.
+                      * Imported `demon' and `loop' modes from xlockmore.
+Changes since 3.05:   * Oops, the "default-n" visual descriptor was broken;
+                        it was always installing a colormap if the
+                        `installColormap' preference was set, meaning that
+                        `xearth', `xv' and friends were using the wrong
+                        colors on 8-bit systems.
+                      * Turned off HAVE_PING in `sonar', since it compiles
+                        on some Linux systems, but not others of similar
+                        vintage...
+Changes since 3.04:   * Fixed an off-by-1 in `distort'.
+                      * Added `sonar' hack.
+                      * New version of `glplanet' (with stars.)
+                      * Made all hacks exit when you type `q' or `ESC' at them,
+                        and made them obey the WM_DELETE_WINDOW ClientMessage.
+                      * Fixed a nonfatal buffer overrun in lament (note:
+                        lament still doesn't work with MesaGL 3.0: it dies in
+                        lambda_textured_triangle1(), which is Mesa's bug, not
+                        mine.)
+Changes since 3.03:   * Added an `xscreensaver.spec' file, to make it easier
+                        for other folks to generate RPMs.
+                      * Made the password code work on HPUX in the situation
+                        where: ``enhanced security'' is available; but not 
+                        used; but the user typed a password more than 8
+                        characters long anyway.  FTSOHPUX.
+Changes since 3.02:   * Made locking work when passwd aging is enabled.
+                      * Added support for PAM (Pluggable Authentication
+                        Modules.)  It is still turned off by default, though,
+                        since it doesn't seem to work on Solaris 2.6, and has
+                        been behaving erratically on Red Hat 5.1.
+                      * Made each possible authentication method be tried in
+                        turn until one succeeds; this means that Kerberos is
+                        being used, we will first check Kerberos, and if that
+                        fails, will then consult the local password file.
+                        Likewise with PAM.
+                      * Save and restore the bits under the passwd dialog,
+                        to avoid leaving a black rectangle behind when 
+                        unlocking is cancelled.
+Changes since 3.01:   * Not everyone has sys/select.h, sigh...
+Changes since 3.00:   * Some fixes to `reflect'.
+                     * Configure tweaks.
+                     * Made it log unsuccessful attempts to unlock the screen
+                       to syslog.
+                     * Fixed a bug where `xscreensaver-demo' could be seeing
+                       a different programs list than `xscreensaver' did.
+Changes since 2.34:   * The xscreensaver daemon no longer links against Motif
+                       or Athena: demo-mode and the preferences panel are no
+                       longer built in to the daemon, but are now handled by
+                       an external program, `xscreensaver-demo'.
+                       (I decided that this, along with the recent addition
+                       of the `.xscreensaver' config file, justified bumping
+                       the version number to 3.00, since this is a fairly
+                       major architectural change.)
+                     * Lines in the `*programs' resource may now begin with
+                       the character "-", meaning "don't run this hack."
+                       In this way, it's possible to disable a hack without
+                       throwing away the information about it (making it 
+                       easier to change your mind later.)  Eventually the
+                       preferences/demo mode GUI should represent this as a
+                       checkbox or something.
+                     * Fixed a short race condition where it was possible for
+                       xscreensaver to die with a BadWindow error if it was
+                       blanking the screen just as another window was being
+                       deleted.
+                     * Made it possible to disable specific modes in `bsod'.
+Changes since 2.33:   * Fixed a bug that was making `pipes' generate way too
+                       many valves.  Made the viewpoint in `pipes' be selected
+                       randomly instead of always being -10 degrees.
+                     * Fixed a bug in the XSHM code, in the case where the
+                       server supports the XSHM extension but is not the same
+                       machine as the client.
+                     * Made `rd-bomb' default to taking up the whole screen.
+                     * Made it not try to do fading/unfading if no PseudoColor
+                       visuals exist.
+                     * Initial attempt at supporting VT-locking (doesn't work
+                       yet.)
+                     * Eliminated the `captureStdout' resource; now
+                       `captureStderr' controls both streams.
+                     * Added `-capture-stderr' and `-no-capture-stderr'
+                       command-line arguments.
+                     * Added `glplanet' hack.
+                     * When a hack is selected with `xscreensaver-command
+                       -select', that hack will be used until further notice
+                       (until the saver turns off, or another activation
+                       command is issued.)
+Changes since 2.32:   * Made `xscreensaver-command' print error messages:
+                       the xscreensaver daemon now responds to ClientMessage
+                       events by writing a response message on a window
+                       property, instead of just writing to its stderr.
+                     * Made the ~/.xscreensaver file be automatically reloaded
+                       when the file date changes.
+                     * The password dialog and splash screen no longer depend
+                       on Motif or Athena.  This should clear up a number of
+                       focus problems, and is the first step on the path
+                       toward moving all of the Motif/Athena/whatever code
+                       out of the xscreensaver daemon, and into external
+                       processes.
+                     * Don't complain about LessTif 0.86 any more, since the
+                       new password dialog makes that problem go away.
+                     * Configure tweaks for Irix 6.5, SunOS 5.something.
+                     * New `-reflect' option to `distort'.
+Changes since 2.31:   * Added reading and writing of a ~/.xscreensaver file,
+                       so that the Preferences panel can save its settings.
+                     * New version of `rubik'.
+                     * Added `-select N' argument to `xscreensaver-command'.
+                     * Oops, left out some of the `bubbles3d' files...
+Changes since 2.30:   * The cursor was invisible in the password dialog. Fixed.
+                     * Made configure warn against MesaGL 2.6.
+                     * Fixed X error at startup when using non-default visual.
+                     * New version of `crystal', `ant', and `atlantis' from
+                       xlockmore.
+                     * New hack, `bubble3d'.
+                     * Added some new modes to `bsod'.
+Changes since 2.29:   * Changed the order in which -lSM and -lICE are linked
+                       to be after Motif instead of before (Lesstif on Irix
+                       needs this.)
+Changes since 2.28:   * Work around a bash bug in configure.
+                     * Tweaked HPUX paths again.  FTSOHPUX.
+                     * Made configure recommend against LessTif 0.86, due
+                       to a bug in that version that causes a security hole
+                       in the screen locking code.  LessTif 0.87 will fix it.
+                     * Made all of the `--with' options to `configure' accept
+                       a directory option as well (so that --with-motif=/FOO
+                       will add -I/FOO/include -L/FOO/lib).  I believe this is
+                       the Configure Party Line of how do to such things.
+                     * Fixed a bug where the mouse was left un-grabbed
+                       after the first time the graphics hack was changed
+                       (simplified all of the mouse-grabbing logic.)
+                     * Maybe possibly perhaps made `vidwhacker' really not
+                       leave stray xv windows around.  This time for sure.
+                     * Added a new erase mode (random dots fizzling out.)
+                     * Added `-prefs' argument to `xscreensaver-command',
+                       that brings up the Preferences dialog directly (it
+                       seems that nobody ever noticed the `Preferences' button
+                       on the Demo Mode dialog, maybe this will help.)
+                     * Added a splash screen.  Turn it off with *splash:false.
+Changes since 2.27:   * Better macsbug text in `bsod'.
+                     * New version of `distort' with many new modes.
+                     * Plugged a leak in `coral'.
+                     * Tweaked configure for HPUX.
+                     * Removed some compiler warnings.
+                     * More consistent usage of stderr versus stdout.
+                     * More diagnostics should an X error occur.
+                     * Fixed a possible crash in SGI-specific unfading code.
+Changes since 2.26:   * Improved version of `distort'.
+                     * Made `lament' compile against OpenGL 1.0 (though it
+                       still requires 1.1 to work properly.)
+                     * Updated my email address and home page.
+Changes since 2.24:   * Improved motion in `rd-bomb'.
+                     * Added XSHM (shared memory extension) support to the
+                       `distort', `interference', `moire', `rd-bomb', and
+                       `swirl' hacks, which speeds them up a bit.
+                     * Added `lament' hack.
+Changes since 2.23:   * Tweaked the order of the -L options again.
+                     * Cleaned up configure's `--help' message.
+                     * Added `kumppa' hack.
+                     * Smarter maze-solving algorithm in `maze'.
+                     * Took `xlyap' out of the default list of hacks, since
+                       it's just incredibly buggy (and slow.)  Maybe someday
+                       someone will fix it...
+                     * Added `distort' hack, but didn't add it to the default
+                       list (yet) because it's still too slow.
+                     * Made the Athena demo dialog look more like the Motif
+                       version; it has a text-entry field now, too.
+                     * Made the Athena password dialog echo asterisks, like
+                       Motif does, instead of using a flyspeck font.
+                     * Some random configure tweaks.
+                     * Added a `timestamp' resource that makes the `-verbose'
+                       messages include the time at which they were printed.
+Changes since 2.22:   * The fix for SGI's ``scheme'' nonsense broke things, and
+                       let the user's "*background" resource show through.
+                       Fixed it in a different way.
+Changes since 2.21:   * Added support for the DPMS server extension (Display
+                       Power Management System.)
+                     * Made configure advertize the `--enable-subdir' option a
+                       little more, since that seemed to cause some people
+                       stress.  Also, made that directory be built into the
+                       xscreensaver executable, as a hardcoded prefix to
+                       $PATH.  (Might help, shouldn't hurt.)
+                     * Made configure prefer the two-arg gettimeofday to the
+                       one-arg version, since AIX doesn't have any prototypes.
+                     * Made it work with Xaw3d (the 3D Athena library.)
+                     * Made `make install' create directories as necessary.
+                     * New version of lmorph from Sverre.
+                     * Added `crystal' and `discreet' hacks from xlockmore.
+                     * Added a new mode to `bsod'.
+Changes since 2.20:   * Made `xscreensaver-command -time' use different words.
+                       (It now describes the two states as "screen blanked
+                       since..."  and "screen non-blanked since..." instead of
+                       "active since..." and "inactive since..." which a lot
+                       of people interpreted as meaning the opposite of what
+                       was intended.)
+                     * Improved some error messages, in the hopes of making
+                       the distinction between the xscreensaver and
+                       xscreensaver-command programs more obvious.
+                     * Rewrote (and reorganized) parts of the xscreensaver and
+                       xscreensaver-command manual pages.
+                     * Renamed xscreensaver's `-lock' command-line option to
+                       be `-lock-mode', to avoid confusion with the `-lock'
+                       option to xscreensaver-command, which does a totally
+                       different thing.
+                     * Removed xscreensaver's `-demo' command-line option for
+                       a similar reason; use `xscreensaver-command -demo'
+                       instead.
+                     * Disabled SGI's ``scheme'' nonsense in a better way than
+                       fully-qualifying the background colors in every single
+                       hack.
+                     * Fixed some other minor cosmetic problems when *sgiMode
+                       is turned on.
+                     * Fixed an X error in `bsod -root' (how ironic...)
+Changes since 2.19:   * Fixed a bug that caused the mouse to sometimes not be
+                       grabbed properly (meaning the window manager menu could
+                       pop up over the demo-mode display.)
+                     * Fixed a bug that made the stderr output sometimes get
+                       printed twice.
+                     * Fixed a bug that made the demo-mode scrollbar move too
+                       fast.
+                     * Protected against a possible buffer overflow.
+                     * Made `vidwhacker' not leave stray xv windows around.
+                     * New version of `ant' so that Bagley doesn't calve.
+                     * Make configure on AIX get XShm from the right library.
+Changes since 2.18:   * One file was missing from the tar file.         Fixed.
+Changes since 2.17:   * Oops, atlantis wasn't being built by default.  Fixed.
+                     * Added `epicycle' hack.
+                     * Added `interference' hack.
+                     * Added `truchet' hack.
+                     * Added `bsod' hack.
+                     * Added some new modes to `vidwhacker'.
+Changes since 2.16:   * Added a -window-id argument to most hacks, so that they
+                       can draw on arbitrary externally-provided windows.
+                     * Synched with xlockmore 4.11a01.
+                     * Added `flow' hack.
+                     * Added `atlantis' GL hack.
+                     * Renamed `puzzle' hack to `jigsaw', since xlock already
+                       had a different mode called `puzzle'.
+                     * Made it self-configure properly when Motif 2.1.0 is
+                       being used (requires -lXp now, sigh...)
+Changes since 2.15:   * Made `flag' able to do XPM images.
+                     * New look for the xscreensaver logo (`xroger').
+                     * Fixed compilation error on Suns with adjunct passwords.
+                     * Got multi-architecture builds working again.
+                     * Some configure tweaks for building on HPUX and Solaris.
+                     * Fixed bug in decayscreen.
+                     * Fixed typo in passwd.c.
+                     * Made `cynosure' not die when colormap is full.
+Changes since 2.14:   * Added `cynosure' hack.
+                     * Added `moire2' hack.
+                     * Tweaked `erase.c' some more.
+                     * Made unfading a bit smoother.
+                     * Added `vidwhacker' hack (not installed by default.)
+                     * Added `stairs' hack.
+                     * Split `escher' into `cage' and `moebius', as per
+                       xlockmore.
+                     * Changed subprocess handling to use sigaction() instead
+                       of signal() if it's available (this is necessary for
+                       SCO but should work fine on other systems too.)
+                     * Various other tweaks.
+Changes since 2.13:   * Better fix for the Motif drag-and-die lossage.
+                     * Put in some kludges to work around a LessTif bug.
+                     * XScreenSaver is known to work with LessTif 0.82 now.
+                     * Made fading work on high-end SGI video hardware.
+                     * Fixed another SGI-specific bug in screen grabbing;
+                       will the madness never cease?
+                     * Fixed another crash in `xlyap'.
+Changes since 2.12:   * Made `decayscreen' do directions other than down.
+                     * Improved `puzzle'.
+                     * Fixed a crash in `xlyap'.
+                     * Added CDE info to the man page, removed `cde.txt'.
+                     * Configure tweaks for Zippy.
+                     * Turned off the signal handling in `bubbles' because
+                       it was sometimes failing to die.
+                     * Added `hacks/xscreensaver-sgigl.c' to make it possible
+                       to run SGI's ElectroPaint hack (/usr/demos/bin/ep)
+                       with xscreensaver.  Finally!
+                     * Fixed a buffer overrun in the locking code that some
+                       wily, malicious cracker must have slipped in.
+                     * Disabled Motif drag-and-drool in the dialog box
+                       buttons, since it's broken in some old versions of
+                       Motif.
+Changes since 2.11:   * Added `README.debugging'.
+                     * Added `puzzle' hack.
+                     * Added `xlyap' hack.
+                     * Added `default-n' as a visual name, so that one can
+                       have -install on by default, but turn it off for
+                       certain poorly-behaved hacks (like xv.)
+                     * Added support for grabbing frames of external video
+                       (on SGI) to the screen-grabbing hacks (decayscreen,
+                       slidescreen, slip, blitspin, and puzzle.)
+                     * Improved look of tiles in `slidescreen'; fixed its
+                       color allocation problem.
+Changes since 2.10:   * Tweaked `blitspin', added it to the default list.
+                     * Added `lissie', `mountain', `triangle', `worm',
+                       `rotor', and `ant' from xlockmore.
+                     * Updated `sierpinski', `galaxy', and `lisa'.
+                     * Thickened the lines in `braid' and `lmorph'.
+                     * Updated VMS makefiles.
+                     * Renamed `fract' to `vines'.
+                     * Added `xjack' hack.
+                     * Made a few more hacks use erase.c, and added a few
+                       more wipe styles.
+                     * Fixed compilation problem with Sun's version of OpenGL.
+                     * Added ability to use sigaction() instead of signal()

+                     * Ported `swirl' and `bouboule' hacks from xlockmore.
+                     * Made the driver more careful about not leaving bits on
+                       the screen, or allowing other windows to raise
+                       themselves: it now re-blanks the screen every so often.
+                     * Added `-time' option to `xscreensaver-command'.
+                     * Improved SGI screen-grabbing some more: now it can grab
+                       TrueColor screens into PseudoColor windows and have the
+                       colors still come out semi-reasonably.
+Changes since 1.29:   * Made `slidescreen' and `decayscreen' work better on
+                       SGIs when windows of different visuals are present, by
+                       using the XReadDisplay() extension to get a true 24-bit
+                       image out of the frame buffer.
+                     * Made `noseguy' be in color, if compiled with XPM.

+                       `ifs', `julia', `laser', `lightning', `penrose',
+                       `sierpinski', `slip', `spiral', and `strange' hacks
+                       from xlockmore.
+                     * Merged `hopalong' hack with a more recent version.
+                     * Added `cde.txt'.
+Changes since 1.27:   * Added `deco', `moire', and `kaleidescope' hacks.
+                     * Merged in support for non-Motif locking and demo mode.
+                     * Made `blitspin' and `bubbles' work in TrueColor.
+                     * Fixed a stupid bug I introduced in `imsmap'.

+Changes since 1.26:   * Added support for SGI SCREEN_SAVER extension.
+                     * Made `fade' and `unfade' work on 8-bit SGIs.
+                     * Made the dialog boxes more Motify.
+                     * Added `bubbles' hack.
+Changes since 1.25:   * Added `lmorph' hack.
+                     * Added viscosity and mouse-control to attraction.
+                     * Fixed possible bad color choices in qix and attraction.
+                     * Added ramp-mode to halo.
+                     * Added a new RNG, which is faster and more portable
+                       than using the RNG in libc.
+                     * Made locking work on SCO.
+                     * Various other minor tweaks that I don't remember.
+Changes since 1.24:   * Made it capture the stdout/stderr of its subprocesses
+                       and present them on the screensaver window itself.
+                     * Made demo mode work correctly with non-default visuals
+                       and color maps, instead of always using the defaults.
+                     * Added -visual argument to all included screenhacks.
+                     * Support for the R6 MIT-SCREEN-SAVER server extension.
+                     * Made the demo mode list scroll properly.
+                     * Added `pedal' hack.
+Changes since 1.23:   * Fixed some private-colormap oddities in slidescreen,
+                       decayscreen, and xroger.  Fixed apparent conservation-
+                       of-mass problem in pyro; made the shrapnel round.
+Changes since 1.22:   * Minor tweaks for IRIX5; fixed locking race condition.
+Changes since 1.21:   * Minor tweaks for X11R6.
+                     * Fixes for non-default visuals.
+Changes since 1.20:   * Fixed bug in color blitspin; added default image.
+                     * Added diagnostics to noseguy.  Fixed off-by-one
+                       error in flame.  Added some missing casts.

+                     * Fixed a minor Motif dialog text field bug.
+                     * Fixed yet another XPointer-not-defined-in-R4 bug.

+                     * Moved the hacks into their own directory.
+                     * Made all `time' parameters accept the 00:00:00 syntax,
+                       so that even the parameters which are normally read as
+                       minutes can be specified in seconds.
+                     * Added colormap cycling to `imsmap'.

+OpenVMS port of Xscreensavser version 2.10     October 1997
+==========================================
+
+Xscreensaver distribution can be found in 3 subdirectories:
+
+[.DRIVER]   The Xscreensaver and Xscreensaver-command programs.
+[.HACKS]    Graphic demos ,can be run either through the xscreensaver program 
+            or standalone.
+[.UTILS]    A small libraries of various utilities.
+
+This port has been tested with  VAX VMS 6.1 (compiled with DEC 5 5.0 and
+Motif 1.2) and AXP VMS 6.2 (compiled with DEC C 5.0 and Motif 1.2-4). 
+
+To rebuild, you need to rebuild [.UTILS] directory first and create the
+object library (look at the end of COMPILE*.COM procedure).
+
+You can now build the [.HACKS] directory and the [.DRIVER] directory.
+
+A one-step build is now available via the MAKEVMS.COM script. 
+
+WARNING : before building [.HACKS], you may need to correct some of the
+DECwindows bitmap files. Some files are bogus !! (they have a long line of 
+null chars  at the end). These files are under 
+SYS$COMMON:[DECW$INCLUDE.BITMAPS] directory:
+
+STIPPLE.XBM
+HLINES2.XBM
+LIGHT_GRAY.XBM
+ROOT_WEAVES.XBM
+VLINES2.XBM
+
+These files are all used by Greynetic demo.
+
+Nota: link procedure automagically select appropriate X and Motif Libraries
+(X11R4/Motif 1.1 - X11R5/Motif 1.2). 
+
+The SETUP.COM procedure gives you a definition of all DCL foreign command
+symbols needed to run Xscreensaver and all the graphic hacks. You need to
+modify this procedure if you install these programs in another directory tree.
+
+You can easily add new graphic demos without recompiling Xscreensaver. You just
+need to add them in resource file XSCREENSAVER.DAT. This file (originally
+present in [.DRIVER] directory ) can be installed under your SYS$LOGIN 
+directory for a per-user customization basis. You can also install it under 
+the system-wide user resource directory SYS$COMMON:[DECW$DEFAULT.USER] 
+(with (W:RE) protections). The new graphics hack must be run in root-window 
+mode to be accepted by Xscreensaver.
+
+The graphic demos are spawn into subprocess created by the system() call (in
+the Unix version the execvp() call is used).
+
+The VMS passord checking programs were picked up in the Xlock distribution.
+
+Enjoy,

+                              XScreenSaver
+
+              a handy guide for creating useful bug reports
+
+                                --------
+
+    It's hard to imagine, but sometimes, xscreensaver has bugs.  This
+    document gives some hints for isolating them; the more information
+    you can give me about the problem, the better the odds that I'll be
+    able to fix it.  But, if you don't have time to go through these
+    steps, please report the bug anyway -- even vague bug reports can
+    be better than no bug report at all.
+
+                                --------
+STEP ZERO:
+
+    What are you doing here?  Go read README, and then the man page.
+
+STEP ZERO, PART TWO:
+
+    Do you have the most recent version?  Go make sure.
+    http://www.jwz.org/xscreensaver/.
+
+COMPILATION PROBLEMS:
+
+    If you get an error running the `configure' script, the first thing
+    you should try is deleting the `config.cache' file, and running again.
+    If that doesn't fix it, the information I'll need to see to make
+    sense of the problem is the following:
+
+        *  everything printed to stderr/stdout when you first ran
+           ./configure;
+
+        *  the contents of the `config.log' file.
+
+    Make sure you blow away the config.cache file before regenerating
+    this info, or else the `config.log' file will be mostly empty/useless.
+
+    Experience seems to show that the most common configure problem is
+    that sites have gcc installed, but installed improperly.  The
+    configure script will always try to use gcc in preference to another
+    compiler if gcc exists, so if gcc exists but is broken, it won't
+    work.  Your options are:
+
+        *  get someone to fix the gcc installation;
+
+        *  rearrange your $PATH so that the broken gcc is not on it;
+
+        *  or pass $CC in the environment, like so:
+
+              csh:  setenv CC cc ; ./configure
+              sh:   CC=cc ; ./configure
+
+    Before doing this, you'll need to nuke `config.cache'.
+
+    If you get errors about not being able to find Motif or Athena (the
+    Xm/ or Xaw/ header files), and you can't find them on your system,
+    then your system is horked and your vendor is lame.  Perhaps the
+    problem is that you don't have some kind of ``development option''
+    installed.  Xt/ and Xaw/ (Athena) are free and available on all
+    systems; Xm/ (Motif) is available on all commercial systems except
+    SunOS 4.x and some early releases of Solaris.  For Linux and other
+    free Unixes systems, a Motif clone is available from
+    http://www.lesstif.org/.
+
+RUN-TIME PROBLEMS:
+
+    For runtime errors, it's important to keep in mind that there are
+    two parts to xscreensaver: there is the screensaver driver process
+    (the daemon that detects idleness, deals with locking, and launches
+    the demos); and there are the demos themselves (independent programs
+    that draw pretty pictures.)
+
+        *  Compile with `make CFLAGS=-g' (so that if you get a core
+          dump, there will be debugging info in it.)
+
+        *  What platform are you running on?  What does the included
+           `./config.guess' shell script print?
+
+        *  Is the problem in the driver (`xscreensaver'), the GUI
+           (`xscreensaver-demo'), or in the graphics hacks?
+
+        *  If the problem is in the GUI, was the it built using
+           Motif, Lesstif, or Athena?  Which version?
+
+        *  If the problem is in one (or more) of the hacks, which ones?
+           If you're not sure, try running `xscreensaver-demo' to go
+           through the list of them and see which work and which don't.
+
+        *  Does the problem occur when running that hack by hand, in
+           its own window (i.e., when started with no command-line args)?
+
+        *  Does the problem occur when running that hack by hand, on
+           the root window (i.e., when started with the `-root' option)?
+
+        *  IMPORTANT: What visual are you using?  Send the output of
+           the `xdpyinfo' command.
+
+        *  Does the problem go away if you give the program a different
+           `-visual' argument?  (For example, `-visual pseudocolor' or
+           `-visual truecolor'.)
+
+        *  IMPORTANT: What exactly goes wrong?  No, I don't know what
+           you mean by "crash".  Does it print an "X Error" and exit?
+           Does it dump core?  Does it go into a loop?
+
+        *  If it dumps core, what does the core file say?  Run the
+           program under a debugger, and show me the stack trace.
+           To extract a stack trace from a core file with gdb, do this:
+
+              gdb ./the-program ./core
+              bt
+
+           To extract a stack trace from a core file with dbx, do this:
+
+              dbx ./the-program ./core
+              where
+
+           If the bottom few lines of the output don't include the functions
+          `main_loop()' and `main()', then something's wrong: are you sure
+           the core file came from that program?
+
+        *  If it gets an X error, where did it come from?  Run
+           xscreensaver with the `-sync' command-line option.  When `-sync'
+           is used, X errors will cause xscreensaver to dump a core file.
+           Look at the core file with a debugger and show me the stack trace,
+           as above: I need to know where in xscreensaver that X error came
+           from.
+
+    If the problem is with the xscreensaver process itself, or if you
+    can't figure out which demo is causing the problem, or if you can't
+    reproduce the problem in isolation, then you will need to turn on
+    and examine the debugging output of the driver process.
+
+        *  Start `xscreensaver' with the command-line arguments
+
+              -verbose -no-capture
+
+           This will cause it to write a lot of debugging info to the stderr
+           of the xscreensaver process (the `-verbose' option turns on the
+           diagnostics; the `-no-capture' option prevents the data from being
+           displayed on the screensaver window as well.)
+
+           You also might want to use the `-timestamp' option, which will
+           cause the xscreensaver messages to include the time at which
+           they were printed.
+
+        *  If the problem is intermittent, you might want to capture the
+           log information to a file and examine it later.  For example,
+           you could start it from your login script like this (csh syntax):
+
+              ( cd ~/src/xscreensaver/ ; \
+                xscreensaver -sync -verbose -timestamp -no-capture \
+                >>&LOG & )

+/*  First, some background: there are three distinct server extensions which
+ *  are useful to a screen saver program: they are XIDLE, MIT-SCREEN-SAVER, 
+ *  and SCREEN_SAVER.
+ *
+ *  The XIDLE extension resides in .../contrib/extensions/xidle/ on the X11R5
+ *  contrib tape.  This extension lets the client get accurate idle-time 
+ *  information from the X server in a potentially more reliable way than by
+ *  simply watching for keyboard and mouse activity.  However, the XIDLE 
+ *  extension has apparently not been ported to X11R6.
+ *
+ *  The SCREEN_SAVER extension is found (as far as I know) only in the SGI
+ *  X server, and it exists in all releases since (at least) Irix 5.  The
+ *  relevant header file is /usr/include/X11/extensions/XScreenSaver.h.
+ *
+ *  The similarly-named MIT-SCREEN-SAVER extension came into existence long
+ *  after the SGI SCREEN_SAVER extension was already in use, and resides in
+ *  .../contrib/extensions/screensaver/ on the X11R6 contrib tape.  It is
+ *  also found in certain recent X servers built in to NCD X terminals.
+ *
+ *     The MIT extension does basically the same thing that the XIDLE extension
+ *     does, but there are two things wrong with it: first, because of the way
+ *     the extension was designed, the `fade' option to XScreenSaver will be
+ *     uglier: just before the screen fades out, there will be an unattractive
+ *     flicker to black, because this extension blanks the screen *before*
+ *     telling us that it is time to do so.  Second, this extension is known to
+ *     be buggy; on the systems I use, it works, but some people have reported
+ *     X server crashes as a result of using it.  XScreenSaver uses this
+ *     extension rather conservatively, because when I tried to use any of its
+ *     more complicated features, I could get it to crash the server at the
+ *     drop of a hat.
+ *
+ *     In short, the MIT-SCREEN-SAVER extension is a piece of junk.  The older
+ *     SGI SCREEN_SAVER extension works great, as does XIDLE.  It would be nice
+ *     If those two existed on more systems, that is, would be adopted by the
+ *     X Consortium in favor of their inferior "not-invented-here" entry.

+/*  First, some background: there are three distinct server extensions which
+ *  are useful to a screen saver program: they are XIDLE, MIT-SCREEN-SAVER, 
+ *  and SCREEN_SAVER.
+ *
+ *  The XIDLE extension resides in .../contrib/extensions/xidle/ on the X11R5
+ *  contrib tape.  This extension lets the client get accurate idle-time 
+ *  information from the X server in a potentially more reliable way than by
+ *  simply watching for keyboard and mouse activity.  However, the XIDLE 
+ *  extension has apparently not been ported to X11R6.
+ *
+ *  The SCREEN_SAVER extension is found (as far as I know) only in the SGI
+ *  X server, and it exists in all releases since (at least) Irix 5.  The
+ *  relevant header file is /usr/include/X11/extensions/XScreenSaver.h.
+ *
+ *  The similarly-named MIT-SCREEN-SAVER extension came into existence long
+ *  after the SGI SCREEN_SAVER extension was already in use, and resides in
+ *  .../contrib/extensions/screensaver/ on the X11R6 contrib tape.  It is
+ *  also found in certain recent X servers built in to NCD X terminals.
+ *
+ *     The MIT extension does basically the same thing that the XIDLE extension
+ *     does, but there are two things wrong with it: first, because of the way
+ *     the extension was designed, the `fade' option to XScreenSaver will be
+ *     uglier: just before the screen fades out, there will be an unattractive
+ *     flicker to black, because this extension blanks the screen *before*
+ *     telling us that it is time to do so.  Second, this extension is known to
+ *     be buggy; on the systems I use, it works, but some people have reported
+ *     X server crashes as a result of using it.  XScreenSaver uses this
+ *     extension rather conservatively, because when I tried to use any of its
+ *     more complicated features, I could get it to crash the server at the
+ *     drop of a hat.
+ *
+ *     In short, the MIT-SCREEN-SAVER extension is a piece of junk.  The older
+ *     SGI SCREEN_SAVER extension works great, as does XIDLE.  It would be nice
+ *     If those two existed on more systems, that is, would be adopted by the
+ *     X Consortium in favor of their inferior "not-invented-here" entry.

+Installation options:
+
+  --enable-subdir=DIR     Put the demo programs in a subdirectory of \`bindir',
+                          instead of putting them in bindir itself.  You can
+                          specify the name of the subdirectory.  For example,
+                          \`--exec-prefix=/usr/local --enable-subdir=demos'
+                          would put xscreensaver in /usr/local/bin/, and would
+                          put the demos in /usr/local/bin/demos/.  (If DIR
+                          begins with /, then bindir will not be prepended.)
+
+  --disable-subdir        Just put the demos in \`bindir' (this is the default.)
+"
+ac_help="$ac_help
+Except where noted, all of the --with options below can also take a
+directory argument: for example, \`--with-motif=/opt/Motif'.  That would
+cause /opt/Motif/include/ to be added to the -I list, and /opt/Motif/lib/
+to be added to the -L list, assuming those directories exist.  
+
+By default, support for each of these options will be built in, if the
+relevant library routines exist.  At run time, they will then be used
+only if the X server being used supports them.  Each --with option has
+a corresponding --without option, to override building support for them
+at all.

+      # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.

+      # are the same division as 10.x.  However, there are no symlinks to
+      # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
+      # arguments are always necessary.
+      #
+      # However, X11R6 was available on HPUX 9.x as a patch: if that

+      # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know

+      #
+      # On HPUX 10.x, the parts of X that HP considers "standard" live in
+      # /usr/{include,lib}/X11R6/.  The parts that HP doesn't consider
+      # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
+      # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
+      # Also, there are symlinks from /usr/include/ and /usr/lib/ into
+      # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
+      # you don't need any -I or -L arguments.
+      #
+      # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
+      # are the same division as 10.x.  However, there are no symlinks to
+      # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
+      # arguments are always necessary.
+      #
+      # However, X11R6 was available on HPUX 9.x as a patch: if that
+      # patch was installed, then all of X11R6 went in to
+      # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
+      #
+      # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
+      # whether R5 was available as a patch; R6 undoubtedly was not.)
+      #
+      # So.  We try and use the highest numbered pair of
+      # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
+      # that are available.  We do not mix and match different versions

+      #     /usr/contrib/X11R6/ could be installed as a patch, what was in
+      #     that contrib directory?  Did it contain so-called "standard"
+      #     X11R6, or did it include Xaw and Xmu as well?  If the former,
+      #     where did one find Xaw and Xmu on 9.x R6 systems?  Would this
+      #     be a situation where one had to reach into the R5 headers and

+!            a screen saver and locker for the X window system
+!                            by Jamie Zawinski
+!
+!                              version 3.16
+!                                23-Jun-99
+!
+! See "man xscreensaver" for more info.  The latest version is always
+! available at http://www.jwz.org/xscreensaver/
+
+
+! These resources, when placed in the system-wide app-defaults directory
+! (e.g., /usr/lib/X11/app-defaults/XScreenSaver) will provide the default
+! settings for new users.  However, if you have a ".xscreensaver" file in
+! your home directory, the settings in that file take precedence.

+
+! Turning on "installColormap" interacts erratically with twm and tvtwm,
+! but seems to work fine with mwm and olwm.  Try it and see.  If your
+! screen turns some color other than black, the window manager is buggy,
+! and you need to set this resource to False (or get a WM that works.)
+!
+*installColormap:      True
+
+
+! Any program which can draw on the root window will work as a screensaver.
+! The following resource enumerates them.
+!
+! Programs are separated by newlines (specified in resource files with \n).
+! Lines may be continued with a lone \ at the end of the line.
+!
+! Each line is an `sh' command.
+!
+! If the first (non-blank) character on the line is "-", then that means
+! that this command is disabled: it's still in the list, but it won't ever
+! be used.  (This is just to make it easy to disable and then re-enable 
+! them later.)
+!
+! If the first word on the line is the name of a visual followed by a
+! colon, then that visual will be used for the program, if it is available.
+! If no such visual is available, then the program will be skipped.  In
+! this way, you can specify that you want certain programs to run only
+! on color screens, and others only on mono screens, by making use of the
+! magic visual names "color" and "mono".  Likewise, if some hacks prefer
+! colormaps, but others prefer 24-bit windows, that also can be arranged
+! (in this case, by using "PseudoColor:" versus "TrueColor:".)
+!
+! Some of the screenhacks are written using OpenGL.  OpenGL programs are
+! a bit different than normal X programs, in that they prefer visuals that
+! are *half* as deep as the screen.  You can tell xscreensaver to select a
+! good visual for a GL program by using the magic visual name "GL".
+!
+! All programs must be launched in such a way that they draw on the root
+! window; they should not be spawned in the background with "&".  If shell
+! metacharacters are used, they must be understandable to `sh', not `csh'
+! (the $SHELL variable is not consulted, for unfortunate but good reasons.)
+!
+! Be sure to check out Demo Mode: run the `xscreensaver-demo' program to
+! edit the current list of programs interactively, try out the various modes,
+! and change other parameters.  See the man page for details.

+!              xswarm -r 2>&-                                          \n\

+!
+! xtacy is ok, but it only works on the default visual.  We can satisfy
+! that constraint like so:
+!
+!     default: xtacy -root -delay 100 -funky -number 3                 \n\
+!     default: xtacy -root -delay 100 -gravity                         \n\
+!     default: xtacy -root -delay 100 -mixer                           \n\
+!     default: xtacy -root -delay 100 -taffy -pal 4                    \n\
+! 
+! To display a randomized slideshow of images, you can do something like this:
+!
+!     default-n:  xv -root -rmode 5 -random -viewonly -wloop              \
+!                    -wait 30 $HOME/bitmaps/*.jpg                       \n\
+!
+! Note that we've used "default-n" as the visual name, rather than just
+! "default": this means "default visual, no install", that is, it's like
+! specifying the command-line arguments "-visual default -no-install".
+! This is necessary because, when XV is running in "-root" mode, it always
+! assumes that the default visual and colormap are being used, rather than 
+! examining the window it is drawing on to see what visual and colormap it
+! has.  If we didn't force the default visual to be used, xv would get an
+! X error.  If we didn't force the default colormap to be installed, the
+! colors would be all wrong.  "default-i" may also be used as a visual name
+! (meaning, "-visual default -install") but you probably won't ever need
+! to use that.
+!
+! XEarth is nice, too:
+!
+!     default-n: xearth -nostars -wait 0 -timewarp 400 -pos sunrel/38/-30
+!
+!
+! Some of the GL demos that SGI ships work with XScreenSaver; most don't.
+! XScreenSaver includes a program (not built or installed by default)
+! called "xscreensaver-sgigl".  To use the SGI demos with XScreenSaver,
+! build that program, and use it to launch the SGI demos.  For example,
+! on Irix 6.2, you can do this:
+!
+!     xscreensaver-sgigl /usr/demos/bin/ep -S
+!     xscreensaver-sgigl /usr/demos/bin/bongo
+!
+! On Irix 6.3, things have moved, so you need to do it like this:
+!
+!     xscreensaver-sgigl /usr/sbin/ep -S
+!
+! You can also use the "ant" demo, but first you need to wrap a shell script
+! around it that cds to its home directory, so that it can find its files;
+! and also pass it the -S argument, to prevent it from forking.
+!
+!
+! Also, since these actually end up mapping their own windows instead of
+! drawing on the XScreenSaver-provided root, when they are being run from
+! demo-mode, you can't pop up the demo-mode dialog just by clicking the
+! mouse: you must first type ESC to make the SGI programs exit.  This sucks.
+! Things should work properly when they are being run by xscreensaver in
+! non-demo-mode, however.
+!
+! Basically, the SGI demo writers went out of their way to make my life hell.

+

+     keyboard-traversable, but that's less bad than not being able to try
+     out new switches by typing them into the text field.
+
+     XmSelectionBox(3M) says in the "Additional Behavior" section:
+         KActivate:
+                   Calls the activate callbacks for the button with
+                   the keyboard focus.  [... ]  In a List widget or
+                   single-line Text widget, the List or Text action
+                   associated with KActivate is called before the
+                   SelectionBox actions associated with KActivate."
+
+     So they take it as a given that when running activateCallback on a single-
+     line Text widget, you'll also want to run activateCallback on whatever the
+     currently-focussed button is as well!  Morons!  Villains!  Shitheads!
+
+     (Perhaps there's some way to override XmSelectionBox's KActivate behavior.
+     I doubt it, but if there is, I don't know it.)

+   is configured at all.  That is, there is no way to tell the difference
+   between "authentication of the FOO service is not allowed" and "the
+   user typed the wrong password."
+
+   On RedHat 5.1 systems, if a service name is not known, it defaults to
+   being not allowed (because the fallback service, /etc/pam.d/other, is
+   set to `pam_deny'.)
+
+   On Solaris 2.6 systems, unknown services default to authenticating normally.
+
+   So, we could simply require that the person who installs xscreensaver
+   set up an "xscreensaver" PAM service.  However, if we went that route,
+   it would have a really awful failure mode: the failure mode would be that
+   xscreensaver was willing to *lock* the screen, but would be unwilling to
+   *unlock* the screen.  (With the non-PAM password code, the analagous
+   situation -- security not being configured properly, for example do to the
+   executable not being installed as setuid root -- the failure mode is much
+   more palettable, in that xscreensaver will refuse to *lock* the screen,
+   because it can know up front that there is no password that will work.)
+
+   Another route would be to have the service name to consult be computed at
+   compile-time (perhaps with a configure option.)  However, that doesn't
+   really solve the problem, because it means that the same executable might
+   work fine on one machine, but refuse to unlock when run on another
+   machine.
+
+   Another alternative would be to look in /etc/pam.conf or /etc/pam.d/ at
+   runtime to see what services actually exist.  But I think that's no good,
+   because who is to say that the PAM info is actually specified in those
+   files?  Opening and reading those files is not a part of the PAM client
+   API, so it's not guarenteed to work on any given system.
+
+   An alternative I tried was to specify a list of services to try, and to
+   try them all in turn ("xscreensaver", "xlock", "xdm", and "login").
+   This worked, but it was slow (and I also had to do some contortions to
+   work around bugs in Linux PAM 0.64-3.)

+     - I want to know it's pid so that I can kill it.
+     - I would like to receive a message when it dies of natural causes.
+     - I want the spawned process to have user-specified arguments.
+
+     If shell metacharacters are present (wildcards, backquotes, etc), the
+     only way to parse those arguments is to run a shell to do the parsing
+     for you.
+
+     And the only way to know the pid of the process is to fork() and exec()
+     it in the spawned side of the fork.
+
+     But if you're running a shell to parse your arguments, this gives you
+     the pid of the *shell*, not the pid of the *process* that you're
+     actually interested in, which is an *inferior* of the shell.  This also
+     means that the SIGCHLD you get applies to the shell, not its inferior.
+     (Why isn't that sufficient?  I don't remember any more, but it turns
+     out that it isn't.)
+
+     So, the only solution, when metacharacters are present, is to force the
+     shell to exec() its inferior.  What a fucking hack!  We prepend "exec "
+     to the command string, and hope it doesn't contain unquoted semicolons
+     or ampersands (we don't search for them, because we don't want to
+     prohibit their use in quoted strings (messages, for example) and parsing
+     out the various quote characters is too much of a pain.)
+
+     (Actually, Clint Wong <clint@jts.com> points out that process groups
+     might be used to take care of this problem; this may be worth considering
+     some day, except that, 1: this code works now, so why fix it, and 2: from
+     what I've seen in Emacs, dealing with process groups isn't especially

+       wrong keyboard.)  The way we do this is by noting that the $DISPLAY is
+       pointing to display 0 on the local machine.  It *could* be that display
+       1 is also on the local machine (e.g., two X servers, each on a different
+       virtual-terminal) but it's also possible that screen 1 is an X terminal,
+       using this machine as the host.  So we can't take that chance.
+
+     * Second, one can only access these interrupt numbers in a completely
+       and utterly brain-damaged way.  You would think that one would use an
+       ioctl for this.  But no.  The ONLY way to get this information is to
+       open the pseudo-file /proc/interrupts AS A FILE, and read the numbers
+       out of it TEXTUALLY.  Because this is Unix, and all the world's a file,
+       and the only real data type is the short-line sequence of ASCII bytes.
+
+       Now it's all well and good that the /proc/interrupts pseudo-file
+       exists; that's a clever idea, and a useful API for things that are
+       already textually oriented, like shell scripts, and users doing
+       interactive debugging sessions.  But to make a *C PROGRAM* open a file
+       and parse the textual representation of integers out of it is just
+       insane.
+
+     * Third, you can't just hold the file open, and fseek() back to the
+       beginning to get updated data!  If you do that, the data never changes.
+       And I don't want to call open() every five seconds, because I don't want
+       to risk going to disk for any inodes.  It turns out that if you dup()
+       it early, then each copy gets fresh data, so we can get around that in
+       this way (but for how many releases, one might wonder?)
+
+     * Fourth, the format of the output of the /proc/interrupts file is
+       undocumented, and has changed several times already!  In Linux 2.0.33,
+       even on a multiprocessor machine, it looks like this:
+
+          0:  309453991   timer
+          1:    4771729   keyboard
+   
+       but on later kernels with MP machines, it looks like this:
+
+                   CPU0       CPU1
+          0:    1671450    1672618    IO-APIC-edge  timer
+          1:      13037      13495    IO-APIC-edge  keyboard
+
+       Joy!  So how are we expected to parse that?  Well, this code doesn't
+       parse it: it saves the last line with the string "keyboard" in it, and
+       does a string-comparison to note when it has changed.
+
+   Thanks to Nat Friedman <nat@nat.org> for figuring out all of this crap.
+
+   Note that this only checks for lines with "keyboard" or "PS/2 Mouse" in
+   them.  If you have a serial mouse, it won't detect that, it will only detect
+   keyboard activity.  That's because there's no way to tell the difference
+   between a serial mouse and a general serial port, and it would be somewhat
+   unfortunate to have the screensaver turn off when the modem on COM1 burped.

+         in multiples of 8 pixels when in 8-bit mode, and in multiples of 4
+         pixels in 16-bit mode.  I don't know what it does in 24- and 32-bit
+         mode, because I don't have enough video memory to find out.
+
+         I consider it a bug that XF86VidModeGetViewPort() is telling me the
+         server's *target* scroll position rather than the server's *actual*
+         scroll position.  David Dawes agrees, and says they may fix this in
+         XFree86 4.0, but it's notrivial.
+
+         He also confirms that this behavior is server-dependent, so the
+         actual scroll position cannot be reliably determined by the client.
+         So... that means the only solution is to provide a ``sandbox''
+         around the blackout window -- we make the window be up to N pixels
+         larger than the viewport on both the left and right sides.  That
+         means some part of the outer edges of each hack might not be
+         visible, but screw it.
+
+         I'm going to guess that 16 pixels is enough, and that the Y dimension
+         doesn't have this problem.
+
+         The drawback of doing this, of course, is that some of the screenhacks
+         will still look pretty stupid -- for example, "slidescreen" will cut
+         off the left and right edges of the grid, etc.

+\n\
+  This program provides external control of a running xscreensaver process.\n\
+  Version %s, copyright (c) 1991-1999 Jamie Zawinski <jwz@jwz.org>.\n\
+\n\
+  The xscreensaver program is a daemon that runs in the background.\n\
+  You control a running xscreensaver process by sending it messages\n\
+  with this program, xscreensaver-command.  See the man pages for\n\
+  details.  These are the arguments understood by xscreensaver-command:\n\
+\n\
+  -demo         Ask the xscreensaver process to enter interactive demo mode.\n\
+\n\
+  -prefs        Ask the xscreensaver process to bring up the preferences\n\
+                panel.\n\
+\n\
+  -activate     Turn on the screensaver (blank the screen), as if the user\n\
+                had been idle for long enough.\n\
+\n\
+  -deactivate   Turns off the screensaver (un-blank the screen), as if user\n\
+                activity had been detected.\n\
+\n\
+  -cycle        If the screensaver is active (the screen is blanked), then\n\
+                stop the current graphics demo and run a new one (chosen\n\
+                randomly.)\n\
+\n\
+  -next         Like either -activate or -cycle, depending on which is more\n\
+                appropriate, except that the graphics hack that will be run\n\
+                is the next one in the list, instead of a randomly-chosen\n\
+                one.  In other words, repeatedly executing -next will cause\n\
+                the xscreensaver process to invoke each graphics demo\n\
+                sequentially.  (Though using the -demo option is probably\n\
+                an easier way to accomplish that.)\n\
+\n\
+  -prev         Like -next, but goes in the other direction.\n\
+\n\
+  -select <N>   Like -activate, but runs the Nth element in the list of\n\
+                hacks.  By knowing what is in the `programs' list, and in\n\
+                what order, you can use this to activate the screensaver\n\
+                with a particular graphics demo.  (The first element in the\n\
+                list is numbered 1, not 0.)\n\
+\n\
+  -exit         Causes the xscreensaver process to exit gracefully.  This is\n\
+                roughly the same as killing the process with `kill', but it\n\
+                is easier, since you don't need to first figure out the pid.\n\
+                (Note that one must *never* kill xscreensaver with -9!)\n\
+\n\
+  -restart      Causes the screensaver process to exit and then restart with\n\
+                the same command line arguments as last time.  Do this after\n\
+                you've changed your X resource settings, to cause\n\
+                xscreensaver to notice the changes.\n\
+\n\
+  -lock         Tells the running xscreensaver process to lock the screen\n\
+                immediately.  This is like -activate, but forces locking as\n\
+                well, even if locking is not the default.  If the saver is\n\
+                already active, this causes it to be locked as well.\n\
+\n\
+  -throttle     Temporarily switch to ``blank screen'' mode, and don't run\n\
+                any display modes at all, until the screensaver is next\n\
+                de-activated.  This is useful if you're using a machine\n\
+                remotely, and you find that some display modes are using too\n\
+                much CPU.\n\
+\n\
+  -unthrottle   Turn `-throttle' off and resume normal behavior.\n\
+\n\
+  -version      Prints the version of xscreensaver that is currently running\n\
+                on the display -- that is, the actual version number of the\n\
+                running xscreensaver background process, rather than the\n\
+                version number of xscreensaver-command.\n\
+\n\
+  -time         Prints the time at which the screensaver last activated or\n\
+                deactivated (roughly, how long the user has been idle or\n\
+                non-idle -- but not quite, since it only tells you when the\n\
+                screen became blanked or un-blanked.)\n\
+\n\
+  See the man page for more details.\n\

+.SH DESCRIPTION
+The \fIxscreensaver\-command\fP program controls a running \fIxscreensaver\fP
+process by sending it client-messages.
+
+.BR xscreensaver (1)
+has a client-server model: the xscreensaver process is a
+daemon that runs in the background; it is controlled by other
+foreground programs such as \fIxscreensaver-command\fP and
+.BR xscreensaver\-demo (1).
+
+This program, \fIxscreensaver-command\fP, is a command-line-oriented tool; the 
+.BR xscreensaver\-demo (1).
+program is a graphical tool.
+.SH OPTIONS
+.I xscreensaver-command
+accepts the following command-line options:
+.TP 8
+.B \-help
+Prints a brief summary of command-line options.
+.TP 8
+.B \-demo
+This just launches the
+.BR xscreensaver\-demo (1)
+program, in which one can experiment with the various graphics hacks
+available, and edit parameters.
+.TP 8
+.B \-demo \fP\fInumber\fP
+When the \fI\-demo\fP option is followed by an integer, it instructs 
+the \fIxscreensaver\fP daemon to run that hack, and wait for the user
+to click the mouse before deactivating (i.e., mouse motion does not
+deactivate.)  This is the mechanism by which
+.BR xscreensaver\-demo (1)
+communicates with the
+.BR xscreensaver (1)
+daemon.  (The first hack in the list is numbered 1, not 0.)
+.TP 8
+.B \-prefs
+Like the no-argument form of \fI\-demo\fP, but brings up that program's
+Preferences panel by default.
+.TP 8
+.B \-activate
+Tell xscreensaver to turn on immediately (that is, blank the screen, as if
+the user had been idle for long enough.)  The screensaver will deactivate as
+soon as there is any user activity, as usual.
+
+It is useful to run this from a menu; you may wish to run it as
+.EX
+sleep 5 ; xscreensaver-command -activate
+.EE
+to be sure that you have time to take your hand off the mouse before
+the screensaver comes on.  (Because if you jiggle the mouse, xscreensaver
+will notice, and deactivate.)
+.TP 8
+.B \-deactivate
+If the screensaver is active (the screen is blanked), this command will
+deactivate it just as if there had been keyboard or mouse activity.  
+If locking is enabled, then the screensaver will prompt for a password
+as usual.
+.TP 8
+.B \-cycle
+If the screensaver is active (the screen is blanked), then stop the current
+graphics demo and run a new one (chosen randomly.)
+.TP 8
+.B \-next
+This is like either \fI\-activate\fP or \fI\-cycle\fP, depending on which is
+more appropriate, except that the graphics hack that will be run is the next
+one in the list, instead of a randomly-chosen one.  In other words, 
+repeatedly executing -next will cause the xscreensaver process to invoke each
+graphics demo sequentially.  (Though using the \fI\-demo\fP option is probably
+an easier way to accomplish that.)
+.TP 8
+.B \-prev
+This is like \fI\-next\fP, but cycles in the other direction.
+.TP 8
+.B \-select \fInumber\fP
+Like \fI\-activate\fP, but runs the \fIN\fPth element in the list of hacks.
+By knowing what is in the \fIprograms\fP list, and in what order, you can use
+this to activate the screensaver with a particular graphics demo.  (The first
+element in the list is numbered 1, not 0.)
+.TP 8
+.B \-exit
+Causes the xscreensaver process to exit gracefully.  This is roughly the same
+as killing the process with
+.BR kill (1),
+but it is easier, since you don't need to first figure out the pid.  
+
+.B Warning:
+never use \fIkill -9\fP with \fIxscreensaver\fP while the screensaver is
+active.  If you are using a virtual root window manager, that can leave
+things in an inconsistent state, and you may need to restart your window
+manager to repair the damage.
+.TP 8
+.B \-lock
+Tells the running xscreensaver process to lock the screen immediately.  
+This is like \fI\-activate\fP, but forces locking as well, even if locking
+is not the default (that is, even if xscreensaver's \fIlock\fP resource is
+false, and even if the \fIlockTimeout\fP resource is non-zero.)
+
+Note that locking doesn't work unless the \fIxscreensaver\fP process is
+running as you.  See 
+.BR xscreensaver (1)
+for details.
+.TP 8
+.B \-throttle
+Temporarily switch to ``blank screen'' mode, and don't run any display modes
+at all, until the screensaver is next de-activated.  This is useful if you're
+using a machine remotely, and you find that some display modes are using too
+much CPU.  
+
+(If you want to do this \fIpermanently\fP, that is, you want the screen saver
+to only blank the screen and not run demos at all, then set the \fIprograms\fP
+resource to an empty list:  See
+.BR xscreensaver (1)
+for details.)
+.TP 8
+.B \-unthrottle
+Turn `-throttle' mode off and resume normal behavior.
+.TP 8
+.B \-version
+Prints the version of xscreensaver that is currently running on the display:
+that is, the actual version number of the running xscreensaver background 
+process, rather than the version number of xscreensaver-command.  (To see
+the version number of \fIxscreensaver-command\fP itself, use 
+the \fI\-help\fP option.)
+.TP 8
+.B \-time
+Prints the time at which the screensaver last activated or 
+deactivated (roughly, how long the user has been idle or non-idle: but 
+not quite, since it only tells you when the screen became blanked or
+un-blanked.)
+.TP 8
+.B \-restart
+Causes the screensaver process to exit and then restart with the same command
+line arguments as last time.  Do this after you've changed the resource
+database, to cause xscreensaver to notice the changes.
+
+.B Warning:
+if you have a \fI.xscreensaver\fP file, this might not do what you 
+expect.  You're probably better off killing the existing 
+xscreensaver (with \fIxscreensaver\-command -exit\fP) and then
+launching it again.
+
+The important point is, you need to make sure that the xscreensaver 
+process is running as you.  If it's not, it won't be reading the

+.SH NAME
+xscreensaver-demo - interactively control the background xscreensaver daemon
+.SH SYNOPSIS
+.B xscreensaver\-demo
+[\-display \fIhost:display.screen\fP] [\-prefs] [\-xrm \fIresources\fP]
+.SH DESCRIPTION
+The \fIxscreensaver\-demo\fP program is a graphical front-end for 
+setting the parameters used by the background
+.BR xscreensaver (1)
+daemon.
+It is essentially two things: a tool for editing the \fI~/.xscreensaver\fP
+file; and a tool for demoing the various graphics hacks that 
+the \fIxscreensaver\fP daemon will launch.
+
+The main dialog box contains a scrolling list, a text field, and a number 
+of buttons.  
+
+Double-clicking on one of the programs in the list will run it.  The screen
+will go black, and the program will run in full-screen mode, just as it would
+if the \fIxscreensaver\fP daemon had launched it.  Clicking the mouse again
+will stop the demo and un-blank the screen, making the dialog box visible 
+again.
+
+Single-clicking in the list will place the indicated program and its args
+in the text field to be edited.  Edit the arguments and hit return to run
+the program with the parameters you have specified.  This will also save
+your changes to your \fI~/.xscreensaver\fP file: so any changes you make
+in this way are persistent.
+
+If one of the lines in the scrolling list begins with the character "-",
+then that means that the program is disabled: \fIxscreensaver\fP will not
+select it to be run (though you can still try it out by clicking on it.)
+Rather than just deleting the programs you don't want to run, you might
+want to disable them in this way instead, so that you can more easily change
+your mind later.
+
+If the line begins with the name of a visual, followed by a colon, then
+that program will only be run on that kind of visual.  For example, you can
+specify that a particular program should only be run if color is available,
+and another should only be run in monochrome.  See the discussion of 
+the \fIprograms\fP parameter in the \fIConfiguration\fP section of the
+.BR xscreensaver (1)
+manual.
+
+The buttons are:
+.TP 8
+.B Run Next
+Clicking this button will run the next program in the list after the 
+currently-selected one, and will wrap around to the top when it reaches
+the bottom.
+.TP 8
+.B Run Previous
+Opposite of Run Next; at the top, it wraps around to the bottom.
+.TP 8
+.B Preferences
+This pops up a second dialog box, in which you have the option to 
+interactively change most of the screensaver's operational parameters,
+such as its timeouts, and whether it should lock the screen.  When you
+click OK, your chosen settings will take effect immediately, and will
+also be saved to the \fI~/.xscreensaver\fP file in your home directory,
+so that the settings will persist next time.
+.TP 8
+.B Quit
+Exits the \fIxscreensaver-demo\fP program.  The background \fIxscreensaver\fP
+daemon will continue running as before.
+.P
+The Preferences dialog box lets you change the following settings.
+
+(There are more settings available, but these are the most commonly used
+ones; see the manual for
+.BR xscreensaver (1)
+for other parameters that can be set by editing the \fI~/.xscreensaver\fP
+file, or the X resource database.)
+.TP 8
+.B Saver Timeout
+After the user has been idle this long, the \fIxscreensaver\fP daemon
+will blank the screen.
+.TP 8
+.B Cycle Timeout
+After the screensaver has been running for this long, the currently
+running graphics demo will be killed, and a new one started.  
+If this is 0, then the graphics demo will never be changed:
+only one demo will run until the screensaver is deactivated by user 
+activity.
+.TP 8
+.B Verbose\ 
+Whether to print lots of debugging information.
+.TP 8
+.B Install Colormap
+Whether to install a private colormap while the screensaver is active, so
+that the graphics hacks can get as many colors as possible.  (This only
+applies when the screen's default visual is being used, since non-default
+visuals get their own colormaps automatically.)  This can also be overridden
+on a per-demo basis.
+.TP 8
+.B Fade Colormap
+If selected, then when the screensaver activates, the current contents
+of the screen will fade to black instead of simply winking out.  This only
+works on displays with writable colormaps, that is, if the screen's default
+visual is a PseudoColor visual.  A fade will also be done when
+switching graphics hacks (when the \fICycle Timeout\fP expires.)
+.TP 8
+.B Unfade Colormap
+The complement to \fIFade Colormap\fP: if selected, then when the screensaver
+deactivates, the original contents of the screen will fade in from black
+instead of appearing immediately.  This only works on displays with writable
+colormaps, and when \fIFade Colormap\fP is also selected.
+.TP 8
+.B Fade Duration
+When fading or unfading are selected, this controls how long the fade will
+take.
+.TP 8
+.B Fade Ticks
+This controls how many times a second the colormap will be changed to 
+effect a fade.  Higher numbers yield smoother fades, but may make the
+fades take longer than the specified number of seconds, if your server
+isn't fast enough to keep up.
+.TP 8
+.B Require Password
+Whether the screen saver should lock the screen when it activates.
+.TP 8
+.B Lock Timeout
+If \fIRequire Password\fP is selected, this controls the length of 
+the ``grace period'' between when the screensaver activates, and when the
+screen becomes locked.  For example, if this is 0:05:00, 
+and \fISaver Timeout\fP is 0:10:00, then after 10 minutes, the screen 
+would blank.  If there was user  activity at 12 minutes, no password
+would be required to un-blank the screen.  But, if there was user activity
+at 15 minutes or later (that is, \fILock Timeout\fP minutes after 
+activation) then a password would be required.  The default is 0, meaning
+that if locking is enabled, then a password will be required as soon as the 
+screen blanks.
+.TP 8
+.B Password Timeout
+When the screensaver is prompting for a password, the prompt dialog box will
+stay on the screen for this long before giving up, and reverting to 
+screen-saving mode.
+.SH COMMAND-LINE OPTIONS
+.I xscreensaver\-demo
+accepts the following command line options.
+.TP 8
+.B \-display \fIhost:display.screen\fP
+The X display to use.  The \fIxscreensaver\-demo\fP program will open its
+window on that display, and also control the \fIxscreensaver\fP daemon that
+is managing that same display.
+.TP 8
+.B \-prefs
+Start up in Preferences mode: this is just like launching the program with
+no arguments, and then pressing the \fIPreferences\fP button.
+.P
+It is important that the \fIxscreensaver\fP and \fIxscreensaver\-demo\fP
+processes be running on the same machine, or at least, on two machines
+that share a file system.  When \fIxscreensaver\-demo\fP writes a new version
+of the \fI~/.xscreensaver\fP file, it's important that the \fIxscreensaver\fP
+see that same file.  If the two processes are seeing 
+different \fI~/.xscreensaver\fP files, things will malfunction.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B PATH
+to find the sub-programs to run.  However, note that the sub-programs 
+are actually launched by the \fIxscreensaver\fP daemon, not 
+by \fIxscreensaver-demo\fP itself.  So, what matters is what \fB$PATH\fP
+the \fIxscreensaver\fP program sees.
+.TP 8
+.B HOME
+for the directory in which to read and write the \fI.xscreensaver\fP file.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+
+/*   ========================================================================
+ *   First we wait until the keyboard and mouse become idle for the specified
+ *   amount of time.  We do this in one of three different ways: periodically
+ *   checking with the XIdle server extension; selecting key and mouse events
+ *   on (nearly) all windows; or by waiting for the MIT-SCREEN-SAVER extension
+ *   to send us a "you are idle" event.
+ *
+ *   Then, we map a full screen black window (or, in the case of the 
+ *   MIT-SCREEN-SAVER extension, use the one it gave us.)
+ *
+ *   We place a __SWM_VROOT property on this window, so that newly-started
+ *   clients will think that this window is a "virtual root" window.
+ *
+ *   If there is an existing "virtual root" window (one that already had
+ *   an __SWM_VROOT property) then we remove that property from that window.
+ *   Otherwise, clients would see that window (the real virtual root) instead
+ *   of ours (the impostor.)
+ *
+ *   Then we pick a random program to run, and start it.  Two assumptions 
+ *   are made about this program: that it has been specified with whatever
+ *   command-line options are necessary to make it run on the root window;
+ *   and that it has been compiled with vroot.h, so that it is able to find
+ *   the root window when a virtual-root window manager (or this program) is
+ *   running.
+ *
+ *   Then, we wait for keyboard or mouse events to be generated on the window.
+ *   When they are, we kill the inferior process, unmap the window, and restore
+ *   the __SWM_VROOT property to the real virtual root window if there was one.
+ *
+ *   While we are waiting, we also set up timers so that, after a certain 
+ *   amount of time has passed, we can start a different screenhack.  We do
+ *   this by killing the running child process with SIGTERM, and then starting
+ *   a new one in the same way.
+ *
+ *   If there was a real virtual root, meaning that we removed the __SWM_VROOT
+ *   property from it, meaning we must (absolutely must) restore it before we
+ *   exit, then we set up signal handlers for most signals (SIGINT, SIGTERM,
+ *   etc.) that do this.  Most Xlib and Xt routines are not reentrant, so it
+ *   is not generally safe to call them from signal handlers; however, this
+ *   program spends most of its time waiting, so the window of opportunity 
+ *   when code could be called reentrantly is fairly small; and also, the worst
+ *   that could happen is that the call would fail.  If we've gotten one of
+ *   these signals, then we're on our way out anyway.  If we didn't restore the
+ *   __SWM_VROOT property, that would be very bad, so it's worth a shot.  Note
+ *   that this means that, if you're using a virtual-root window manager, you
+ *   can really fuck up the world by killing this process with "kill -9".
+ *
+ *   This program accepts ClientMessages of type SCREENSAVER; these messages
+ *   may contain the atom ACTIVATE or DEACTIVATE, meaning to turn the 
+ *   screensaver on or off now, regardless of the idleness of the user,
+ *   and a few other things.  The included "xscreensaver_command" program
+ *   sends these messsages.
+ *
+ *   If we don't have the XIdle, MIT-SCREEN-SAVER, or SGI SCREEN_SAVER
+ *   extensions, then we do the XAutoLock trick: notice every window that
+ *   gets created, and wait 30 seconds or so until its creating process has
+ *   settled down, and then select KeyPress events on those windows which
+ *   already select for KeyPress events.  It's important that we not select
+ *   KeyPress on windows which don't select them, because that would
+ *   interfere with event propagation.  This will break if any program
+ *   changes its event mask to contain KeyRelease or PointerMotion more than
+ *   30 seconds after creating the window, but that's probably pretty rare.
+ *   
+ *   The reason that we can't select KeyPresses on windows that don't have
+ *   them already is that, when dispatching a KeyPress event, X finds the
+ *   lowest (leafmost) window in the hierarchy on which *any* client selects
+ *   for KeyPress, and sends the event to that window.  This means that if a
+ *   client had a window with subwindows, and expected to receive KeyPress
+ *   events on the parent window instead of the subwindows, then that client
+ *   would malfunction if some other client selected KeyPress events on the
+ *   subwindows.  It is an incredible misdesign that one client can make
+ *   another client malfunction in this way.
+ *
+ *   To detect mouse motion, we periodically wake up and poll the mouse
+ *   position and button/modifier state, and notice when something has
+ *   changed.  We make this check every five seconds by default, and since the
+ *   screensaver timeout has a granularity of one minute, this makes the
+ *   chance of a false positive very small.  We could detect mouse motion in
+ *   the same way as keyboard activity, but that would suffer from the same
+ *   "client changing event mask" problem that the KeyPress events hack does.
+ *   I think polling is more reliable.
+ *
+ *   None of this crap happens if we're using one of the extensions, so install
+ *   one of them if the description above sounds just too flaky to live.  It
+ *   is, but those are your choices.
+ *
+ *   A third idle-detection option could be implemented (but is not): when
+ *   running on the console display ($DISPLAY is `localhost`:0) and we're on a
+ *   machine where /dev/tty and /dev/mouse have reasonable last-modification
+ *   times, we could just stat() those.  But the incremental benefit of
+ *   implementing this is really small, so forget I said anything.
+ *
+ *   Debugging hints:
+ *     - Have a second terminal handy.
+ *     - Be careful where you set your breakpoints, you don't want this to
+ *       stop under the debugger with the keyboard grabbed or the blackout
+ *       window exposed.
+ *     - If you run your debugger under XEmacs, try M-ESC (x-grab-keyboard)
+ *       to keep your emacs window alive even when xscreensaver has grabbed.
+ *     - Go read the code related to `debug_p'.
+ *     - You probably can't set breakpoints in functions that are called on
+ *       the other side of a call to fork() -- if your clients are dying 
+ *       with signal 5, Trace/BPT Trap, you're losing in this way.
+ *     - If you aren't using a server extension, don't leave this stopped
+ *       under the debugger for very long, or the X input buffer will get
+ *       huge because of the keypress events it's selecting for.  This can
+ *       make your X server wedge with "no more input buffers."
+ *

+.SH DESCRIPTION
+The \fIxscreensaver\fP program waits until the keyboard and mouse have been 
+idle for a period, and then runs a graphics demo chosen at random.  It 
+turns off as soon as there is any mouse or keyboard activity.
+
+This program can lock your terminal in order to prevent others from using it,
+though its default mode of operation is merely to display pretty pictures on
+your screen when it is not in use.  
+
+The benefit that this program has over the combination of the
+.BR xlock (1)
+and
+.BR xautolock (1)
+programs is the ease with which new graphics hacks can be installed.  You
+don't need to recompile (or even re-run) this program to add a new display
+mode.
+.SH GETTING STARTED
+For the impatient, try this:
+.EX
+xscreensaver &
+xscreensaver-demo
+.EE
+The
+.BR xscreensaver-demo (1)
+program should pop up a dialog box that lets you experiment with the
+xscreensaver settings and graphics modes.
+
+.B Note:
+unlike
+.BR xlock (1),
+xscreensaver has a client-server model: the \fIxscreensaver\fP program is a
+daemon that runs in the background; it is controlled by the foreground
+.BR xscreensaver-demo (1)
+and
+.BR xscreensaver-command (1)
+programs.
+.SH CONFIGURATION
+Options to \fIxscreensaver\fP are specified in one of two places: in 
+a \fI.xscreensaver\fP file in your home directory; or in the X resource
+database.  If the \fI.xscreensaver\fP file exists, it overrides any settings
+in the resource database.  
+
+The syntax of the \fI.xscreensaver\fP file is similar to that of
+the \fI.Xdefaults\fP file; for example, to set the \fItimeout\fP paramter
+in the \fI.xscreensaver\fP file, you would write the following:
+.EX
+timeout: 5
+.EE
+whereas, in the \fI.Xdefaults\fP file, you would write
+.EX
+xscreensaver.timeout: 5
+.EE
+If you change a setting in the \fI.xscreensaver\fP file while xscreensaver
+is already running, it will notice this, and reload the file.  (The file will
+be reloaded the next time the screen saver needs to take some action, such as
+blanking or unblanking the screen, or picking a new graphics mode.)
+
+If you change a setting in your X resource database, or if you want
+xscreensaver to notice your changes immediately instead of the next time
+it wakes up, then you will need to tell the running xscreensaver process
+to re-initialize itself, like so:
+.EX
+xscreensaver-command -restart
+.EE
+Note that if you changed the \fI.Xdefaults\fP file, you might also need to run
+.BR xrdb (1):
+.EX
+xrdb < ~/.Xdefaults
+.EE
+If you want to set the system-wide defaults, then make your edits to
+the xscreensaver app-defaults file, which should have been installed
+when xscreensaver itself was installed.  The app-defaults file will
+usually be named /usr/lib/X11/app-defaults/XScreenSaver, but different
+systems might keep it in a different place (for example,
+/usr/openwin/lib/app-defaults/XScreenSaver on Solaris.)
+
+When settings are changed in the Preferences dialog box (see above)
+the current settings will be written to the \fI.xscreensaver\fP file.
+(The \fI.Xdefaults\fP file and the app-defaults file will never be
+written by xscreensaver itself.)
+.PP
+.TP 8
+.B timeout\fP (class \fBTime\fP)
+The screensaver will activate (blank the screen) after the keyboard and
+mouse have been idle for this many minutes.  Default 10 minutes.
+.TP 8
+.B cycle\fP (class \fBTime\fP)
+After the screensaver has been running for this many minutes, the currently
+running graphics-hack sub-process will be killed (with \fBSIGTERM\fP), and a
+new one started.  If this is 0, then the graphics hack will never be changed:
+only one demo will run until the screensaver is deactivated by user activity.
+Default 10 minutes.
+.TP 8
+.B lock\fP (class \fBBoolean\fP)
+Enable locking: before the screensaver will turn off, it will require you 
+to type the password of the logged-in user (really, the person who ran
+xscreensaver), or the root password.  (\fBNote:\fP this doesn't work if the
+screensaver is launched by
+.BR xdm (1)
+because it can't know the user-id of the logged-in user.  See 
+the ``\fIUsing XDM(1)\fP'' section, below.
+.TP 8
+.B lockTimeout\fP (class \fBTime\fP)
+If locking is enabled, this controls the length of the ``grace period''
+between when the screensaver activates, and when the screen becomes locked.
+For example, if this is 5, and \fI\-timeout\fP is 10, then after 10 minutes,
+the screen would blank.  If there was user activity at 12 minutes, no password
+would be required to un-blank the screen.  But, if there was user activity
+at 15 minutes or later (that is, \fI\-lock\-timeout\fP minutes after 
+activation) then a password would be required.  The default is 0, meaning
+that if locking is enabled, then a password will be required as soon as the 
+screen blanks.
+.TP 8
+.B passwdTimeout\fP (class \fBTime\fP)
+If the screen is locked, then this is how many seconds the password dialog box
+should be left on the screen before giving up (default 30 seconds.)  This
+should not be too large: the X server is grabbed for the duration that the
+password dialog box is up (for security purposes) and leaving the server 
+grabbed for too long can cause problems.
+.TP 8
+.B visualID\fP (class \fBVisualID\fP)
+Specify which X visual to use by default.  (Note carefully that this resource
+is called \fBvisualID\fP, not merely \fBvisual\fP; if you set the \fBvisual\fP
+resource instead, things will malfunction in obscure ways for obscure reasons.)
+
+Legal values for the \fBVisualID\fP resource are:
+.RS 8
+.TP 8
+.B default
+Use the screen's default visual (the visual of the root window.)  
+This is the default.
+.TP 8
+.B best
+Use the visual which supports the most colors.  Note, however, that the
+visual with the most colors might be a TrueColor visual, which does not
+support colormap animation.  Some programs have more interesting behavior
+when run on PseudoColor visuals than on TrueColor.
+.TP 8
+.B mono
+Use a monochrome visual, if there is one.
+.TP 8
+.B gray
+Use a grayscale or staticgray visual, if there is one and it has more than
+one plane (that is, it's not monochrome.)
+.TP 8
+.B color
+Use the best of the color visuals, if there are any.
+.TP 8
+.B GL
+Use the visual that is best for OpenGL programs.  (OpenGL programs have
+somewhat different requirements than other X programs.)
+.TP 8
+.I class
+where \fIclass\fP is one of \fBStaticGray\fP, \fBStaticColor\fP, 
+\fBTrueColor\fP, \fBGrayScale\fP, \fBPseudoColor\fP, or \fBDirectColor\fP.
+Selects the deepest visual of the given class.
+.TP 8
+.I number
+where \fInumber\fP (decimal or hex) is interpreted as a visual id number, 
+as reported by the
+.BR xdpyinfo (1)
+program; in this way you can have finer control over exactly which visual
+gets used, for example, to select a shallower one than would otherwise
+have been chosen.
+
+.RE
+.RS 8
+Note that this option specifies only the \fIdefault\fP visual that will
+be used: the visual used may be overridden on a program-by-program basis.
+See the description of the \fBprograms\fP resource, below.
+.RE
+.TP 8
+.B installColormap\fP (class \fBBoolean\fP)
+Install a private colormap while the screensaver is active, so that the
+graphics hacks can get as many colors as possible.  This is the 
+default.  (This only applies when the screen's default visual is being
+used, since non-default visuals get their own colormaps automatically.)
+This can also be overridden on a per-hack basis: see the discussion of
+the \fBdefault\-n\fP name in the section about the \fBprograms\fP resource.
+.TP 8
+.B verbose\fP (class \fBBoolean\fP)
+Whether to print diagnostics.  Default false.

+.TP 8
+.B loadURL\fP (class \fBLoadURL\fP)
+This is the shell command used to load a URL into your web browser.

+.TP 8
+.B nice\fP (class \fBNice\fP)
+The sub-processes created by \fIxscreensaver\fP will be ``niced'' to this

+.TP 8
+.B fade\fP (class \fBBoolean\fP)
+If this is true, then when the screensaver activates, the current contents
+of the screen will fade to black instead of simply winking out.  This only
+works on displays with writable colormaps, that is, if the screen's default
+visual is a PseudoColor visual.  A fade will also be done when
+switching graphics hacks (when the \fIcycle\fP timer expires.)
+Default: true.  
+.TP 8
+.B unfade\fP (class \fBBoolean\fP)
+If this is true, then when the screensaver deactivates, the original contents
+of the screen will fade in from black instead of appearing immediately.  This
+only works on displays with writable colormaps, and if \fIfade\fP is true
+as well.  Default false.
+.TP 8
+.B fadeSeconds\fP (class \fBTime\fP)
+If \fIfade\fP is true, this is how long the fade will be in 
+seconds (default 3 seconds.)
+.TP 8
+.B fadeTicks\fP (class \fBInteger\fP)
+If \fIfade\fP is true, this is how many times a second the colormap will
+be changed to effect a fade.  Higher numbers yield smoother fades, but
+may make the fades take longer than the specified \fIfadeSeconds\fP if
+your server isn't fast enough to keep up.  Default 20.
+.TP 8
+.B captureStderr\fP (class \fBBoolean\fP)
+Whether \fIxscreensaver\fP should redirect its stdout and stderr streams to
+the window itself.  Since its nature is to take over the screen, you would not
+normally see error messages generated by xscreensaver or the sub-programs it
+runs; this resource will cause the output of all relevant programs to be
+drawn on the screensaver window itself, as well as being written to the
+controlling terminal of the screensaver driver process.  Default true.
+.TP 8
+.B font\fP (class \fBFont\fP)
+The font used for the stdout/stderr text, if \fBcaptureStderr\fP is true.
+Default \fB*\-medium\-r\-*\-140\-*\-m\-*\fP (a 14 point fixed-width font.)
+.TP 8
+.B programs\fP (class \fBPrograms\fP)
+The graphics hacks which \fIxscreensaver\fP runs when the user is idle.
+The value of this resource is a string, one \fIsh\fP-syntax command per line.  
+Each line must contain exactly one command: no semicolons, no ampersands.
+
+When the screensaver starts up, one of these is selected at random, and
+run.  After the \fIcycle\fP period expires, it is killed, and another
+is selected and run.
+
+If the value of this resource is empty, then no programs will be run; the
+screen will simply be made black.
+
+If the display has multiple screens, then a different program will be run
+for each screen.  (All screens are blanked and unblanked simultaniously.)
+
+Note that you must escape the newlines; here is an example of how you
+might set this in your \fI~/.xscreensaver\fP file:
+
+.RS 8
+.EX
+programs:  \\
+       qix -root                          \\n\\
+       ico -r -faces -sleep 1 -obj ico    \\n\\

+.RS 8
+Make sure your \fB$PATH\fP environment variable is set up correctly
+\fIbefore\fP xscreensaver is launched, or it won't be able to find the
+programs listed in the \fIprograms\fP resource.
+
+To use a program as a screensaver, two things are required: that that
+program draw on the root window (or be able to be configured to draw on
+the root window); and that that program understand ``virtual root''
+windows, as used by virtual window managers such as
+.BR tvtwm (1).
+(Generally, this is accomplished by just including the \fI"vroot.h"\fP 
+header file in the program's source.)
+
+If there are some programs that you want to run only when using a color
+display, and others that you want to run only when using a monochrome
+display, you can specify that like this:
+.EX
+       mono:   mono-program  -root        \\n\\
+       color:  color-program -root        \\n\\
+.EE
+.RE
+.RS 8
+More generally, you can specify the kind of visual that should be used for
+the window on which the program will be drawing.  For example, if one 
+program works best if it has a colormap, but another works best if it has
+a 24-bit visual, both can be accommodated:
+.EX
+       PseudoColor: cmap-program  -root   \\n\\
+       TrueColor:   24bit-program -root   \\n\\
+.EE
+.RE
+.RS 8
+In addition to the symbolic visual names described above (in the discussion
+of the \fIvisualID\fP resource) one other visual name is supported in
+the \fIprograms\fP list:
+.RS 1
+.TP 4
+.B default-n
+This is like \fBdefault\fP, but also requests the use of the default colormap,
+instead of a private colormap.  (That is, it behaves as if 
+the \fI\-no\-install\fP command-line option was specified, but only for
+this particular hack.)  This is provided because some third-party programs
+that draw on the root window (notably: 
+.BR xv (1),
+and
+.BR xearth (1))
+make assumptions about the visual and colormap of the root window: 
+assumptions which xscreensaver can violate.
+
+.RE
+If you specify a particular visual for a program, and that visual does not
+exist on the screen, then that program will not be chosen to run.  This
+means that on displays with multiple screens of different depths, you can
+arrange for appropriate hacks to be run on each.  For example, if one screen
+is color and the other is monochrome, hacks that look good in mono can be 
+run on one, and hacks that only look good in color will show up on the other.

+.TP 8
+.B pointerPollTime\fP (class \fBTime\fP)
+When server extensions are not in use, this controls how 
+frequently \fIxscreensaver\fP checks to see if the mouse position or buttons
+have changed.  Default 5 seconds.
+.TP 8
+.B windowCreationTimeout\fP (class \fBTime\fP)
+When server extensions are not in use, this controls the delay between when 
+windows are created and when \fIxscreensaver\fP selects events on them.
+Default 30 seconds.
+.TP 8
+.B initialDelay\fP (class \fBTime\fP)
+When server extensions are not in use, \fIxscreensaver\fP will wait this many
+seconds before selecting events on existing windows, under the assumption that 
+\fIxscreensaver\fP is started during your login procedure, and the window 
+state may be in flux.  Default 0.  (This used to default to 30, but that was
+back in the days when slow machines and X terminals were more common...)
+.TP 8
+.B sgiSaverExtension\fP (class \fBBoolean\fP)
+There are a number of different X server extensions which can make
+xscreensaver's job easier.  The next few resources specify whether these
+extensions should be utilized if they are available.
+
+This resource controls whether the SGI \fBSCREEN_SAVER\fP server extension
+will be used to decide whether the user is idle.  This is the default 
+if \fIxscreensaver\fP has been compiled with support for this 
+extension (which is the default on SGI systems.).  If it is available, 
+the \fBSCREEN_SAVER\fP method is faster and more reliable than what will
+be done otherwise, so use it if you can.  (This extension is only available
+on Silicon Graphics systems, unfortunately.)
+.TP 8
+.B mitSaverExtension\fP (class \fBBoolean\fP)
+This resource controls whether the \fBMIT\-SCREEN\-SAVER\fP server extension
+will be used to decide whether the user is idle.  However, the default for
+this resource is \fIfalse\fP, because even if this extension is available,
+it is flaky (and it also makes the \fBfade\fP option not work properly.)
+Use of this extension is not recommended.
+.TP 8
+.B xidleExtension\fP (class \fBBoolean\fP)
+This resource controls whether the \fBXIDLE\fP server extension will be
+used to decide whether the user is idle.  This is the default 
+if \fIxscreensaver\fP has been compiled with support for this extension.
+(This extension is only available for X11R4 and X11R5 systems, unfortunately.)
+.TP 8
+.B procInterrupts\fP (class \fBBoolean\fP)
+This resource controls whether the \fB/proc/interrupts\fP file should be
+consulted to decide whether the user is idle.  This is the default
+if \fIxscreensaver\fP has been compiled on a system which supports this
+mechanism (i.e., Linux systems.)  
+
+The benefit to doing this is that \fIxscreensaver\fP can note that the user
+is active even when the X console is not the active one: if the user is 
+typing in another virtual console, xscreensaver will notice that and will
+fail to activate.  For example, if you're playing Quake in VGA-mode, 
+xscreensaver won't wake up in the middle of your game and start competing 
+for CPU.
+
+The drawback to doing this is that perhaps you \fIreally do\fP want idleness
+on the X console to cause the X display to lock, even if there is activity
+on other virtual consoles.  If you want that, then set this option to False.
+(Or just lock the X console manually.)
+
+The default value for this resource is True, on systems where it works.
+.TP 8
+.B overlayStderr\fP (class \fBBoolean\fP)
+If \fBcaptureStderr\fP is True, and your server supports ``overlay'' visuals,
+then the text will be written into one of the higher layers instead of into
+the same layer as the running screenhack.  Set this to False to disable 
+that (though you shouldn't need to.)
+.TP 8
+.B overlayTextForeground\fP (class \fBForeground\fP)
+The foreground color used for the stdout/stderr text, if \fBcaptureStderr\fP
+is true.  Default: Yellow.
+.TP 8
+.B overlayTextBackground\fP (class \fBBackground\fP)
+The background color used for the stdout/stderr text, if \fBcaptureStderr\fP
+is true.  Default: Black.
+.TP 8

+.SH HOW IT WORKS
+When it is time to activate the screensaver, a full-screen black window is
+created on each screen of the display.  Each window is created in such a way
+that, to any subsequently-created programs, it will appear to be a ``virtual
+root'' window.  Because of this, any program which draws on the root 
+window (and which understands virtual roots) can be used as a screensaver.
+
+When the user becomes active again, the screensaver windows are unmapped, and
+the running subprocesses are killed by sending them \fBSIGTERM\fP.  This is 
+also how the subprocesses are killed when the screensaver decides that it's
+time to run a different demo: the old one is killed and a new one is launched.
+
+Before launching a subprocess, \fIxscreensaver\fP stores an appropriate value
+for \fB$DISPLAY\fP in the environment that the child will recieve.  (This is
+so that if you start \fIxscreensaver\fP with a \fI-display\fP argument, the
+programs which \fIxscreensaver\fP launches will draw on the same display;
+and so that the child will end up drawing on the appropriate screen of a
+multi-headed display.)
+
+When the screensaver turns off, or is killed, care is taken to restore 
+the ``real'' virtual root window if there is one.  Because of this, it is
+important that you not kill the screensaver process with \fIkill -9\fP if
+you are running a virtual-root window manager.  If you kill it with \-9,
+you may need to restart your window manager to repair the damage.  This
+isn't an issue if you aren't running a virtual-root window manager.
+
+For all the gory details, see the commentary at the top of xscreensaver.c.
+
+You can control a running screensaver process by using the
+.BR xscreensaver\-command (1)
+program (which see.)
+.SH POWER MANAGEMENT
+Modern X servers contain support to power down the monitor after an idle
+period.  If the monitor has powered down, then \fIxscreensaver\fP will
+notice this, and will not waste CPU by drawing graphics demos on a black
+screen.  An attempt will also be made to explicitly power the monitor
+back up as soon as user activity is detected.
+
+If your X server supports power management, then
+.BR xset (1)
+will accept a \fBdpms\fP option.  So, if you wanted \fIxscreensaver\fP
+to activate after 5 minutes, but you wanted your monitor to power down
+after one hour (3600 seconds) you would do this:
+.EX
+xset dpms 3600
+.EE
+See the man page for the
+.BR xset (1)
+program for details.  (Note that power management requires both software
+support in the X server, and hardware support in the monitor itself.)
+.SH USING XDM(1)
+You can run \fIxscreensaver\fP from your 
+.BR xdm (1)
+session, so that the screensaver will run even when nobody is logged 
+in on the console.
+
+The trick to using xscreensaver with \fIxdm\fP is this: keep in mind the 
+two very different states in which xscreensaver will be running:
+.RS 4
+.TP 3
+.B 1: Nobody logged in.
+
+If you're thinking of running xscreensaver from XDM at all, then it's 
+probably because you want graphics demos to be running on the console
+when nobody is logged in there.  In this case, xscreensaver will function
+only as a screen saver, not a screen locker: it doesn't make sense
+for xscreensaver to lock the screen, since nobody is logged in yet!
+The only thing on the screen is the XDM login prompt.
+.TP 3
+.B 2: Somebody logged in.
+
+Once someone has logged in through the XDM login window, the situation is
+very different.  For example: now it makes sense to lock the screen (and
+prompt for the logged in user's password); and now xscreensaver should
+consult that user's \fI~/.xscreensaver\fP file; and so on.
+.RE
+
+The difference between these two states comes down to a question of,
+which user is the \fIxscreensaver\fP process running as?  For the first
+state, it doesn't matter.  If you start \fIxscreensaver\fP in the usual
+XDM way, then xscreensaver will probably end up running as root, which 
+is fine for the first case (the ``nobody logged in'' case.)
+
+However, once someone is logged in, running as root is no longer fine:
+because xscreensaver will be consulting root's \fI.xscreensaver\fP file
+instead of that of the logged in user, and won't be prompting for the
+logged in user's password, and so on.  (This is not a security problem,
+it's just not what you want.)
+
+So, once someone has logged in, you want xscreensaver to be running as that
+user.  The way to accomplish this is to kill the old xscreensaver process
+and start a new one (as the new user.)
+
+The simplest way to accomplish all of this is as follows:
+.RS 4
+.TP 3
+.B 1: Launch xscreensaver before anyone logs in.
+
+To the file \fI/usr/lib/X11/xdm/Xsetup\fP, add the lines
+.EX
+xscreensaver-command -exit
+xscreensaver &
+.EE
+This will run xscreensaver as root, over the XDM login window.
+Moving the mouse will cause the screen to un-blank, and allow the user
+to type their password at XDM to log in.
+.TP 3
+.B 2: Restart xscreensaver when someone logs in.
+
+Near the top of the file \fI/usr/lib/X11/xdm/Xsession\fP, add those same lines:
+.EX
+xscreensaver-command -exit
+xscreensaver &
+.EE
+When someone logs in, this will kill off the existing (root) xscreensaver
+process, and start a new one, running as the user who has just logged in.
+If the user's .xscreensaver file requests locking, they'll get it.  They
+will also get their own choice of timeouts, and graphics demos, and so on.
+
+Alternately, each user could just put those lines in their 
+personal \fI~/.xsession\fP files.
+.RE
+
+Make sure you have \fB$PATH\fP set up correctly in the \fIXsetup\fP 
+and \fIXsession\fP scripts, or \fIxdm\fP won't be able to 
+find \fIxscreensaver\fP, and/or \fIxscreensaver\fP won't be able to 
+find its graphics demos.
+
+(If your system does not seem to be executing the \fIXsetup\fP file, you
+may need to configure it to do so: the traditional way to do this is
+to make that file the value of the \fIDisplayManager*setup\fP resource
+in the \fI/usr/lib/X11/xdm/xdm-config\fP file.  See the man page for
+.BR xdm (1)
+for more details.)
+
+It is safe to run \fIxscreensaver\fP as root (as \fIxdm\fP is likely to do.)  
+If run as root, \fIxscreensaver\fP changes its effective user and group ids 
+to something safe (like \fI"nobody"\fP) before connecting to the X server
+or launching user-specified programs.
+
+An unfortunate side effect of this (important) security precaution is that
+it may conflict with cookie-based authentication.
+
+If you get "connection refused" errors when running \fIxscreensaver\fP
+from \fIxdm\fP, then this probably means that you have
+.BR xauth (1)
+or some other security mechanism turned on.  One way around this is to
+add \fB"xhost\ +localhost"\fP to \fIXsetup\fP, just before \fIxscreensaver\fP
+is launched.  
+
+Note that this will give access to the X server to anyone capable of logging
+in to the local machine, so in some environments, this might not be 
+appropriate.  If turning off file-system-based access control is not
+acceptable, then running \fIxscreensaver\fP from the \fIXsetup\fP file
+might not be possible, and xscreensaver will only work when running as
+a normal, unprivileged user.
+
+For more information on the X server's access control mechanisms, see the
+man pages for
+.BR X (1),
+.BR Xsecurity (1),
+.BR xauth (1),
+and
+.BR xhost (1).

+Click on ``\fISet Home Session\fP'' to create a session, then 
+on ``\fIReturn to Home Session\fP'' to select this session each
+time you log in.
+.TP 3
+\fB3: Edit vue.session\fP
+Edit the file \fI~/.vue/sessions/home/vue.session\fP and add to it
+the line
+.EX
+vuesmcmd -screen 0 -cmd "xscreensaver"
+.EE
+This will cause \fIxscreensaver\fP to be launched when you log in.
+(As always, make sure that xscreensaver and the graphics demos are on

+.TP 3
+\fB3: Edit vuewmrc\fP
+Edit the file \fI~/.vue/vuewmrc\fP and add (or change) the Lock control:

+.SH ADDING TO MENUS
+The
+.BR xscreensaver-command (1)
+program is a perfect candidate for something to add to your window manager's
+popup menus.  If you use 
+.BR mwm (1),
+.BR 4Dwm (1),
+.BR twm (1),
+or (probably) any of \fItwm\fP's many descendants, you can do it like this:
+.RS 0
+.TP 3
+\fB1. Create ~/.mwmrc (or ~/.twmrc or ...)\fP
+If you don't have a \fI~/.mwmrc\fP file (or, on SGIs, a \fI~/.4Dwmrc\fP file;
+or, with twm, a \fI~/.twmrc\fP file) then create one by making a copy of
+the \fI/usr/lib/X11/system.mwmrc\fP 
+file (or \fI/usr/lib/X11/twm/system.twmrc\fP, and so on.)
+.TP 3
+\fB2. Add a menu definition.\fP
+Something like this:
+.EX
+menu XScreenSaver
+{
+ "Blank Screen Now" !"sleep 3; xscreensaver-command -activate"
+ "Lock Screen Now"  !"sleep 3; xscreensaver-command -lock"
+ "Screen Saver Demo"         !"xscreensaver-demo"
+ "Screen Saver Preferences"  !"xscreensaver-demo -prefs"
+ "Reinitialize Screen Saver" !"xscreensaver-command -restart"
+ "Kill Screen Saver"         !"xscreensaver-command -exit"
+ "Launch Screen Saver"       !"xscreensaver &"
+}
+.EE
+.TP 3
+\fB3. Add the menu\fP
+For
+.BR mwm (1)
+and
+.BR 4Dwm (1),
+find the section of the file that says \fIMenu DefaultRootMenu\fP.
+For
+.BR twm (1),
+it will probably be \fImenu "defops"\fP.  If you add a line somewhere 
+in that menu definition that reads
+.EX
+  "XScreenSaver"        f.menu XScreenSaver
+.EE
+then this will add an XScreenSaver sub-menu to your default root-window
+popup menu.  Alternately, you could just put the xscreensaver menu items
+directly into the root menu.
+.RE
+
+Other window managers are guaranteed to do things gratuitously differently.
+.SH BUGS
+Bugs?  There are no bugs.  Ok, well, maybe.  If you find one, please let
+me know.  http://www.jwz.org/xscreensaver/bugs.html explains how to
+construct the most useful bug reports.
+.TP 8
+.B Locking and XDM
+If xscreensaver has been launched from 
+.BR xdm (1)
+before anyone has logged in, you will need to kill and then restart the
+xscreensaver daemon after you have logged in, or you will be confused by
+the results.  (For example, locking won't work, and your \fI~/.xscreensaver\fP
+file will be ignored.)
+
+When you are logged in, you want the \fIxscreensaver\fP daemon to be 
+running under \fIyour\fP user id, not as root or some other user.
+
+If it has already been started by \fIxdm\fP, you can kill it by sending
+it the \fBexit\fP command, and then re-launching it as you, by putting
+something like the following in your personal X startup script:
+.EX
+xscreensaver-command -exit
+xscreensaver &
+.EE
+The ``\fIUsing XDM(1)\fP'' section, above, goes into more detail, and explains
+how to configure the system to do this for all users automatically.
+.TP 8
+.B Locking and root logins
+In order for it to be safe for xscreensaver to be launched by \fIxdm\fP,
+certain precautions had to be taken, among them that xscreensaver never
+runs as \fIroot\fP.  In particular, if it is launched as root (as \fIxdm\fP
+is likely to do), xscreensaver will disavow its privileges, and switch 
+itself to a safe user id (such as \fInobody\fP.)
+
+An implication of this is that if you log in as \fIroot\fP on the console, 
+xscreensaver will refuse to lock the screen (because it can't tell
+the difference between \fIroot\fP being logged in on the console, and a
+normal user being logged in on the console but xscreensaver having been 
+launched by the
+.BR xdm (1)
+.I Xsetup
+file.)
+
+The solution to this is simple: you shouldn't be logging in on the console
+as \fIroot\fP in the first place!  (What, are you crazy or something?)  
+
+Proper Unix hygiene dictates that you should log in as yourself, and
+.BR su (1)
+to \fIroot\fP as necessary.  People who spend their day logged in
+as \fIroot\fP are just begging for disaster.
+.TP 8
+.B XAUTH and XDM
+For xscreensaver to work when launched by
+.BR xdm (1),
+programs running on the local machine as user \fI"nobody"\fP must be
+able to connect to the X server.  This means that if you want to run
+xscreensaver on the console while nobody is logged in, you may need
+to disable cookie-based access control (and allow all users who can log
+in to the local machine to connect to the display.)  
+
+You should be sure that this is an acceptable thing to do in your
+environment before doing it.  See the ``\fIUsing XDM(1)\fP'' section, 
+above, for more details.
+
+If anyone has suggestions on how xscreensaver could be made to work with
+.BR xdm (1)
+without first turning off \fI.Xauthority\fP-based access control, please
+let me know.
+.TP 8
+.B Passwords
+If you get an error message at startup like ``couldn't get password
+of \fIuser\fP'' then this probably means that you're on a system in which 
+the
+.BR getpwent (3)
+library routine can only be effectively used by root.  If this is the case, 
+then \fIxscreensaver\fP must be installed as setuid to root in order for
+locking to work.  Care has been taken to make this a safe thing to do.  
+
+It also may mean that your system uses shadow passwords instead of the standard
+.BR getpwent (3)
+interface; in that case, you may need to change some options 
+with \fIconfigure\fP and recompile.
+
+If you change your password after xscreensaver has been launched, it will
+continue using your old password to unlock the screen until xscreensaver
+is restarted.  So, after you change your password, you'll have to do
+.EX
+xscreensaver-command -restart
+.EE
+to make \fIxscreensaver\fP notice.
+.TP 8
+.B PAM Passwords
+If your system uses PAM (Pluggable Authentication Modules), then in order
+for xscreensaver to use PAM properly, PAM must be told about xscreensaver.
+The xscreensaver installation process should update the PAM data (on Linux,
+by creating the file \fI/etc/pam.d/xscreensaver\fP for you, and on Solaris, 
+by telling you what lines to add to the \fI/etc/pam.conf\fP file.)  
+
+If the PAM configuration files do not know about xscreensaver, then 
+you \fImight\fP be in a situation where xscreensaver will refuse to ever
+unlock the screen.
+
+This is a design flaw in PAM (there is no way for a client to tell the
+difference between PAM responding ``I have never heard of your module,''
+and responding, ``you typed the wrong password.'')  As far as I can tell,
+there is no way for xscreensaver to automatically work around this, or
+detect the problem in advance, so if you have PAM, make sure it is
+configured correctly!
+.TP 8
+.B Colormap lossage: TWM
+The \fBinstallColormap\fP option doesn't work very well with the
+.BR twm (1)
+window manager and its descendants.  
+
+There is a race condition between the screensaver and this window manager,
+which can result in the screensaver's colormap not getting installed
+properly, meaning the graphics hacks will appear in essentially random
+colors.  (If the screen goes white instead of black, this is probably why.)
+
+The
+.BR mwm (1)
+and
+.BR olwm (1)
+window managers don't have this problem.  The race condition exists
+because X (really, ICCCM) does not provide a way for an OverrideRedirect 
+window to have its own colormap, short of grabbing the server (which is 
+neither a good idea, nor really possible with the current design.)  What 
+happens is that, as soon as xscreensaver installs its colormap, \fBtwm\fP 
+responds to the resultant \fBColormapNotify\fP event by re-instaling the 
+default colormap.  Apparently, \fBtwm\fP doesn't \fIalways\fP do this; it 
+seems to do it regularly if the screensaver is activated from a menu item, 
+but seems to not do it if the screensaver comes on of its own volition, or 
+is activated from another console.  
+.RS 8
+.TP 4
+.B Attention, window manager authors!
+You should only call
+.BR XInstallColormap (3)
+in response to user events.  That is, it is appropriate to install a colormap
+in response to \fBFocusIn\fP, \fBFocusOut\fP, \fBEnterNotify\fP, 
+and \fBLeaveNotify\fP events; but it is not appropriate to call it in
+response to \fBColormapNotify\fP events.  If you install colormaps in
+response to \fIapplication\fP actions as well as in response to \fIuser\fP
+actions, then you create the situation where it is impossible for 
+override-redirect applications (such as xscreensaver) to display their
+windows in the proper colors.
+.RE
+.TP 8
+.B Colormap lossage: XV, XAnim, XEarth
+Some programs don't operate properly on visuals other than the default one,
+or with colormaps other than the default one.  See the discussion of the
+magic "default-n" visual name in the description of the \fBprograms\fP 
+resource in the \fIConfiguration\fP section.  When programs only work with
+the default colormap, you need to use a syntax like this:
+.EX
+   default-n: xv -root image-1.gif -quit  \\n\\
+   default-n: xearth -nostars -wait 0     \\n\\
+.EE
+It would also work to turn off the \fBinstallColormap\fP option altogether,
+but that would deny extra colors to those programs that \fIcan\fP take
+advantage of them.
+.TP 8
+.B Machine Load
+Although this program ``nices'' the subprocesses that it starts, 
+graphics-intensive subprograms can still overload the machine by causing
+the X server process itself (which is not ``niced'') to suck a lot of 
+cycles.  Care should be taken to slow down programs intended for use as 
+screensavers by inserting strategic calls to
+.BR sleep (3)
+or
+.BR usleep (3)
+(or making liberal use of any \fI\-delay\fP options which the programs 
+may provide.)
+
+Note that the OpenGL-based graphics demos are real pigs on machines that
+don't have texture hardware.
+
+Also, an active screensaver will cause your X server to be pretty much 
+permanently swapped in; but the same is true of any program that draws
+periodically, like 
+.BR xclock (1)
+or
+.BR xload (1).
+.TP 8
+.B Latency and Responsiveness
+If the subprocess is drawing too quickly and the connection to the X
+server is a slow one (such as an X terminal running over a phone line) then 
+the screensaver might not turn off right away when the user becomes active
+again (the
+.BR ico (1)
+demo has this problem if being run in full-speed mode).  This can be
+alleviated by inserting strategic calls to
+.BR XSync (3)
+in code intended for use as a screensaver.  This prevents too much graphics
+activity from being buffered up.
+.TP 8
+.B XFree86's Magic Keystrokes
+The XFree86 X server traps certain magic keystrokes before client programs ever
+see them.  Two that are of note are Ctrl+Alt+Backspace, which causes 
+the X server to exit; and Ctrl+Alt+F\fIn\fP, which switches virtual consoles.
+The X server will respond to these keystrokes even if xscreensaver has the
+screen locked.  Depending on your setup, you might consider this a problem.
+
+Unfortunately, there is no way for xscreensaver itself to override the
+interpretation of these keys.  If you want to disable Ctrl+Alt+Backspace
+globally, you need to set the \fIDontZap\fP flag in 
+your \fI/etc/X11/XF86Config\fP file.  See the
+.BR XF86Config (5)
+manual for details.
+
+There is no way (as far as I can tell) to disable the VT-switching keystrokes.
+
+Some Linux systems come with a VT_LOCKSWITCH ioctl, that one could 
+theoretically use to prevent VT-switching while the screen is locked; 
+but unfortunately, this ioctl can only be used by root, which means
+that xscreensaver can't use it (since xscreensaver disavows its privileges
+shortly after startup, for security reasons.)
+
+Any suggestions for other solutions to this problem are welcome.
+.TP 8
+.B XView Clients
+Apparently there are some problems with XView programs getting confused
+and thinking that the screensaver window is the real root window even when
+the screensaver is not active: ClientMessages intended for the window manager
+are sent to the screensaver window instead.  This could be solved by making
+xscreensaver forward all unrecognised ClientMessages to the real root window,
+but there may be other problems as well.  If anyone has any insight on the
+cause of this problem, please let me know.  (XView is an X11 toolkit that 
+implements the (quite abominable) Sun OpenLook look-and-feel.)
+.TP 8
+.B MIT Extension and Fading
+The \fBMIT-SCREEN-SAVER\fP extension is junk.  Don't use it.
+
+When using the \fBMIT-SCREEN-SAVER\fP extension in conjunction with 
+the \fBfade\fP option, you'll notice an unattractive flicker just before 
+the fade begins.  This is because the server maps a black window just before 
+it tells the \fIxscreensaver\fP process to activate.  The \fIxscreensaver\fP 
+process immediately unmaps that window, but this results in a flicker.  I 
+haven't figured a way  to get around this; it seems to be a fundamental
+property of the (mis-) design of this server extension.
+
+It sure would be nice if someone would implement the \fBSGI SCREEN_SAVER\fP
+extension in XFree86; it's dead simple, and works far better than the
+overengineered and broken \fBMIT-SCREEN-SAVER\fP extension.
+.TP 8
+.B SGI Power Saver
+If you're running Irix 6.3, you might find that your monitor is powering down
+after an hour or two even if you've told it not to.  This is fixed by SGI
+patches 2447 and 2537.
+
+If you're running Irix 6.5, this bug is back.  I don't know a fix.
+.TP 8
+.B MesaGL and Voodoo Cards
+If you have a 3Dfx/Voodoo card, the default settings for xscreensaver will
+run the GL-based graphics demos in such a way that they will not take 
+advantage of the 3D acceleration hardware.  The solution is to change
+the \fBprograms\fP entries for the GL hacks from this:
+.EX
+       gears -root                        \\n\\
+.EE
+to this:
+.EX
+       MESA_GLX_FX=fullscreen  gears      \\n\\
+.EE
+That is, make sure that \fB$MESA_GLX_FX\fP is set to \fIfullscreen\fP, and
+don't tell the program to draw on the root window.  This may seem strange,
+but the setup used by Mesa and these kinds of cards \fIis\fP strange!
+
+For those who don't know, these cards work by sitting between your normal
+video card and the monitor, and seizing control of the monitor when it's 
+time to do 3D.  But this means that accelerated 3D only happens in full-screen
+mode (you can't do it in a window, and you can't see the output of 3D and 2D
+programs simultaniously), and that 3D will probably drive your monitor at a
+lower resolution, as well.  It's bizarre.
+
+If you find that GL programs only work properly when run as root, and not
+as normal users, then the problem is that your \fI/dev/3dfx\fP file is not
+configured properly.  Check the Linux 3Dfx FAQ.
+.TP 8
+.B Keyboard LEDs
+If \fIprocInterrupts\fP is on (which is the default on Linux systems) and
+you're using some program that toggles the state of your keyboard LEDs,
+xscreensaver won't work right: turning those LEDs on or off causes a 
+keyboard interrupt, which xscreensaver will interpret as user activity.
+So if you're using such a program, set the \fIprocInterrupts\fP resource
+to False.
+.TP 8
+.B Extensions
+If you are not making use of one of the server extensions (\fBXIDLE\fP,
+\fBSGI SCREEN_SAVER\fP, or \fBMIT-SCREEN-SAVER\fP), then it is possible, in 
+rare situations, for \fIxscreensaver\fP to interfere with event propagation 
+and make another X program malfunction.  For this to occur, that other
+application would need to \fInot\fP select \fBKeyPress\fP events on its 
+non-leaf windows within the first 30 seconds of their existence, but then 
+select for them later.  In this case, that client \fImight\fP fail to receive 
+those events.  This isn't very likely, since programs generally select a
+constant set of events immediately after creating their windows and then 
+don't change them, but this is the reason that it's a good idea to install 
+and use one of the server extensions instead, to work around this shortcoming
+in the X protocol.
+
+In all these years, I've not heard of even a single case of this happening,
+but it is theoretically possible, so I'm mentioning it for completeness...
+.TP 8
+.B Red Hot Lava
+There need to be a lot more graphics hacks.  In particular, there should be
+a simulation of a Lavalite (tm).
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number, and to inform the sub-programs
+of the screen on which to draw.
+.TP 8
+.B PATH
+to find the sub-programs to run.
+.TP 8
+.B HOME
+for the directory in which to read and write the \fI.xscreensaver\fP file.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+
+       dpms flags...
+                The dpms option allows the DPMS (Energy Star)
+                parameters to be set.  The option can take up to three
+                numerical values, or the `force' flag followed by a
+                DPMS state.  The `force' flags forces the server to
+                immediately switch to the DPMS state specified.  The
+                DPMS state can be one of `standby', `suspend', or
+                `off'.  When numerical values are given, they set the
+                inactivity period before the three modes are activated.
+                The first value given is for the `standby' mode, the
+                second is for the `suspend' mode, and the third is for
+                the `off' mode.  Setting these values implicitly
+                enables the DPMS features.  A value of zero disables a
+                particular mode.
+
+   However, note that the implementation is more than a little bogus,
+   in that there is code in /usr/X11R6/lib/libXdpms.a to implement all
+   the usual server-extension-querying utilities -- but there are no
+   prototypes in any header file!  Thus, the prototypes here.  (The
+   stuff in X11/extensions/dpms.h and X11/extensions/dpmsstr.h define
+   the raw X protcol, they don't define the API to libXdpms.a.)

+This directory contains various graphics hacks.  These are independent from
+the xscreensaver program (in the ../driver/ directory) but some of them use

+ * 04-Apr-96: -neighbors 6 runtime-time option added for hexagonal ants
+ *            (bees), coded from an idea of Jim Propp's in Science News,
+ *            Oct 28, 1995 VOL. 148 page 287
+ * 20-Sep-95: Memory leak in ant fixed.  Now random colors.

+/* Simulation of a pair of quasi-gravitational fields, maybe sorta kinda
+   a little like the strong and weak electromagnetic forces.  Derived from
+   a Lispm screensaver by John Pezaris <pz@mit.edu>.  Mouse control and
+   viscosity added by "Philip Edward Cutone, III" <pc2d+@andrew.cmu.edu>.
+
+   John sez:
+
+   The simulation started out as a purely accurate gravitational simulation,
+   but, with constant simulation step size, I quickly realized the field being
+   simulated while grossly gravitational was, in fact, non-conservative.  It
+   also had the rather annoying behavior of dealing very badly with colliding
+   orbs.  Therefore, I implemented a negative-gravity region (with two
+   thresholds; as I read your code, you only implemented one) to prevent orbs
+   from every coming too close together, and added a viscosity factor if the
+   speed of any orb got too fast.  This provides a nice stable system with
+   interesting behavior.
+
+   I had experimented with a number of fields including the van der Waals
+   force (very interesting orbiting behavior) and 1/r^3 gravity (not as
+   interesting as 1/r^2).  An even normal viscosity (rather than the
+   thresholded version to bleed excess energy) is also not interesting.
+   The 1/r^2, -1/r^2, -10/r^2 thresholds proved not only robust but also
+   interesting -- the orbs never collided and the threshold viscosity fixed
+   the non-conservational problem.
+
+   Philip sez:
+   > An even normal viscosity (rather than the thresholded version to
+   > bleed excess energy) is also not interesting.
+
+   unless you make about 200 points.... set the viscosity to about .8
+   and drag the mouse through it.   it makes a nice wave which travels
+   through the field.
+
+   And (always the troublemaker) Joe Keane <jgk@jgk.org> sez:
+
+   Despite what John sez, the field being simulated is always conservative.
+   The real problem is that it uses a simple hack, computing acceleration
+   *based only on the starting position*, instead of a real differential
+   equation solver.  Thus you'll always have energy coming out of nowhere,
+   although it's most blatant when balls get close together.  If it were
+   done right, you wouldn't need viscosity or artificial limits on how
+   close the balls can get.

+.SH DESCRIPTION
+The \fIattraction\fP program has several visually different modes of 
+operation, all of which are based on the interactions of a set of control
+points which attract each other up to a certain distance, and then begin
+to repel each other.  The attraction/repulsion is proportional to the 
+distance between any two particles.
+.SH OPTIONS
+.I attraction
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-points integer
+How many control points should be used, or 0 to select the number randomly.
+Default 0.  Between 3 and 15 works best.
+.TP 8
+.B \-threshold integer
+The distance (in pixels) from each particle at which the attractive force
+becomes repulsive.  Default 100.
+.TP 8
+.B \-mode "balls | lines | polygons | tails | splines | filled-splines"
+In \fIballs\fP mode (the default) the control points are drawn as filled
+circles.  The larger the circle, the more massive the particle.
+
+In \fIlines\fP mode, the control points are connected by straight lines;
+the effect is something like \fIqix\fP.
+
+In \fIpolygons\fP mode, the control points are connected by straight
+lines, and filled in.  This is most interesting in color.
+
+In \fIsplines\fP mode, a closed spline is interpolated from the control 
+points.
+
+In \fIfilled-splines\fP mode, the splines are filled in instead of being
+outlines.  This is most interesting in color.
+
+In \fItails\fP mode, the path which each particle follows is indicated
+by a worm-like trail, whose length is controlled by the \fIsegments\fP
+parameter.
+.TP 8
+.B \-size integer
+The size of the balls in pixels, or 0, meaning to select the sizes 
+randomly (the default.)  If this is specified, then all balls will be 
+the same size.  This option has an effect in all modes, since the ``size''
+of the balls controls their mass.
+.TP 8
+.B \-segments integer
+If in \fIlines\fP or \fIpolygons\fP mode, how many sets of line segments
+or polygons should be drawn. Default 100.  This has no effect in \fIballs\fP
+mode.  If \fIsegments\fP is 0, then no segments will ever be erased (this
+is only useful in color.)
+.TP 8
+.B \-delay microseconds
+How much of a delay should be introduced between steps of the animation.
+Default 10000, or about 0.01 seconds.
+.TP 8
+.B \-color-shift int
+If on a color display, the color of the line segments or polygons will 
+cycle through the color map.  This specifies how many lines will be drawn
+before a new color is chosen.  (When a small number of colors are available,
+increasing this value will yield smoother transitions.)  Default 3.
+This has no effect in \fIballs\fP mode.
+.TP 8
+.B \-radius
+The size in pixels of the circle on which the points are initially positioned.
+The default is slightly smaller than the size of the window.
+.TP 8
+.B \-glow
+This is consulted only in \fIballs\fP mode.  If this is specified, then 
+the saturation of the colors of the points will vary according to their
+current acceleration.  This has the effect that the balls flare brighter
+when they are reacting to each other most strongly.
+
+In \fIglow\fP mode, all of the balls will be drawn the same (random)
+color, modulo the saturation shifts.  In non-glow mode, the balls will
+each be drawn in a random color that doesn't change.
+.TP 8
+.B \-noglow
+Don't do ``glowing.''  This is the default.
+.TP 8
+.B \-vx pixels
+.TP 8
+.B \-vy pixels
+Initial velocity of the balls.  This has no effect in \fB\-orbit\fP mode.
+.TP 8
+.B \-orbit
+Make the initial force on each ball be tangential to the circle on which
+they are initially placed, with the right velocity to hold them in orbit
+about each other.  After a while, roundoff errors will cause the orbit
+to decay.
+.TP 8
+.B \-vmult float
+In orbit mode, the initial velocity of the balls is multiplied by this;
+a number less than 1 will make the balls pull closer together, and a larger
+number will make them move apart.  The default is 0.9, meaning a slight
+inward pull.
+.TP 8
+.B \-viscosity float
+This sets the viscosity of the hypothetical fluid through which the control
+points move; the default is 1, meaning no resistance.  Values higher than 1
+aren't interesting; lower values cause less motion.
+
+One interesting thing to try is
+.EX
+attraction -viscosity 0.8 -points 75 \\
+  -mouse -geometry =500x500
+.EE
+Give it a few seconds to settle down into a stable clump, and then move
+the mouse through it to make "waves".
+.TP 8
+.B \-mouse
+This will cause the mouse to be considered a control point; it will not be
+drawn, but it will influence the other points, so you can wave the mouse
+and influence the images being created.
+.TP 8
+.B \-no-mouse
+Turns off \fB\-mouse\fP.
+.TP 8
+.B \-mouse-size integer
+In \fB\-mouse\fP mode, this sets the mass of the mouse (analagously to the
+\fB\-size\fP parameter.)
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+/* Rotate a bitmap using using bitblts.
+   The bitmap must be square, and must be a power of 2 in size.
+   This was translated from SmallTalk code which appeared in the
+   August 1981 issue of Byte magazine.
+
+   The input bitmap may be non-square, it is padded and centered
+   with the background color.  Another way would be to subdivide
+   the bitmap into square components and rotate them independently
+   (and preferably in parallel), but I don't think that would be as
+   interesting looking.
+
+   It's too bad almost nothing uses blitter hardware these days,

+.TH XScreenSaver 1 "24-Nov-97" "X Version 11"
+.SH NAME
+blitspin - rotate a bitmap in an interesting way
+.SH SYNOPSIS
+.B blitspin
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-bitmap \fIfilename\fP] [\-delay \fIusecs\fP] [\-delay2 \fIusecs\fP]
+.SH DESCRIPTION
+The \fIblitspin\fP program repeatedly rotates a bitmap by 90 degrees by
+using logical operations: the bitmap is divided into quadrants, and the
+quadrants are shifted clockwise.  Then the same thing is done again with
+progressively smaller quadrants, except that all sub-quadrants of a 
+given size are rotated in parallel.  So this takes \fBO(16*log2(N))\fP 
+blits of size NxN, with the limitation that the image must be square,
+and the size must be a power of 2.
+.SH OPTIONS
+.I blitspin
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-bitmap \fIfilename\fP
+The file name of a bitmap to rotate.  It need not be square: it 
+will be padded with the background color.  If unspecified or the
+string \fI(default)\fP, a builtin bitmap is used.
+
+If support for the \fIXPM\fP library was enabled at compile-time, 
+the specified file may be in \fIXPM\fP format as well as \fIXBM\fP, and 
+thus may be a color image.
+
+The \fB*bitmapFilePath\fP resource will be searched if the bitmap
+name is not a fully-qualified pathname.
+.TP 8
+.B \-grab\-screen
+If this option is specified, then the image which is spun will be grabbed
+from the portion of the screen underlying the blitspin window.  (Or, it
+may come from an external video source: see below.)
+.PP
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long to delay between steps of the rotation process, in microseconds.
+Default is 500000, one-half second.
+.PP
+.TP 8
+.B \-delay2 \fImicroseconds\fP
+How long to delay between each 90-degree rotation, in microseconds.
+Default is 500000, one-half second.
+.B DISPLAY
+to get the default host and display number.
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead.  The following resources control that.
+.PP
+.TP 8
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image, 
+between 0.0 and 1.0.  Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first.  If unspecified, 
+the default camera (from videopanel(1)) will be checked first.  After that, all
+other available video input devices will be checked in order.  
+
+The first one which produces a non-black image will be used.  If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image.  This defaults to 2.2.
+.SH ENVIRONMENT
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * bouboule.c (bouboule mode for xlockmore)
+ *
+ * Sort of starfield for xlockmore. I found that making a starfield for
+ * a 3D engine and thought it could be a nice lock mode. For a real starfield,
+ * I only scale the sort of sphere you see to the whole sky and clip the stars
+ * to the camera screen.
+ *
+ *   Code Copyright 1996 by Jeremie PETIT (jeremie_petit@geocities.com)
+ *
+ *   Use: batchcount is the number of stars.
+ *        cycles is the maximum size for a star
+ *
+ * 15-May-97: jwz@jwz.org: turned into a standalone program.
+ * 04-Sep-96: Added 3d support (Henrik Theiling, theiling@coli-uni-sb.de)
+ * 20-Feb-96: Added tests so that already malloced objects are not
+ *            malloced twice, thanks to the report from <mccomb@interport.net>
+ * 01-Feb-96: Patched by Jouk Jansen <joukj@alpha.chem.uva.nl> for VMS
+ *            Patched by <bagleyd@bigfoot.com> for TrueColor displays
+ * 30-Jan-96: Wrote all that I wanted to.
+ *
+ * DONE: Build up a XArc list and Draw everything once with XFillArcs
+ *       That idea came from looking at swarm code.
+ * DONE: Add an old arcs list for erasing.
+ * DONE: Make center of starfield SinVariable.
+ * DONE: Add some random in the sinvary() function.
+ * DONE: check time for erasing the stars with the two methods and use the
+ *       better one. Note that sometimes the time difference between
+ *       beginning of erasing and its end is negative! I check this, and
+ *       do not use this result when it occurs. If all values are negative,
+ *       the erasing will continue being done in the currently tested mode.
+ * DONE: Allow stars size customization.
+ * DONE: Make sizey be no less than half sizex or no bigger than twice sizex.
+ *
+ * IDEA: A simple check can be performed to know which stars are "behind"
+ *       and which are "in front". So is possible to very simply change
+ *       the drawing mode for these two sorts of stars. BUT: this would lead
+ *       to a rewrite of the XArc list code because drawing should be done
+ *       in two steps: "behind" stars then "in front" stars. Also, what could
+ *       be the difference between the rendering of these two types of stars?
+ * IDEA: Calculate the distance of each star to the "viewer" and render the
+ *       star accordingly to this distance. Same remarks as for previous
+ *       ideas can be pointed out. This would even lead to reget the old stars
+ *       drawing code, that has been replaced by the XFillArcs. On another
+ *       hand, this would allow particular stars (own color, shape...), as
+ *       far as they would be individually drawn. One should be careful to
+ *       draw them according to their distance, that is not drawing a far
+ *       star after a close one.

+.SH NAME
+bouboule - draws spinning 3D blobs
+.SH SYNOPSIS
+.B bouboule
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-cycles \fIinteger\fP] [\-count \fIinteger\fP] [\-3d]
+
+.SH DESCRIPTION
+The \fIbouboule\fP program draws spinning 3D blobs.
+.SH OPTIONS
+.I bouboule
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors used cycle through the hue, making N stops around
+the color wheel.

+.SH NAME
+braid - draws random color-cycling braids around a circle
+.SH SYNOPSIS
+.B braid
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-cycles \fIinteger\fP] [\-count \fIinteger\fP]
+
+.SH DESCRIPTION
+The \fIbraid\fP program draws random color-cycling braids around a circle.
+.SH OPTIONS
+.I braid
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors used cycle through the hue, making N stops around
+the color wheel.
+.TP 8
+.B \-cycles \fIinteger\fP
+
+.TP 8
+.B \-count \fIinteger\fP
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ *      -  Maybe scatter some random bits across the screen,

+ *      -  Should randomize the various hex numbers printed.

+.SH NAME
+bsod - Blue Screen of Death emulator
+.SH SYNOPSIS
+.B bsod
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP]
+[\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install]
+[\-visual \fIvisual\fP] [\-delay \fIseconds\fP]
+.SH DESCRIPTION
+The
+.I bsod
+program is the finest in personal computer emulation.  
+.PP
+.I bsod
+steps through a set of screens, each one a recreation of a different failure
+mode of an operating system.  Systems depicted include Microsoft's Windows 95
+and Windows NT, Commodore-Amiga's AmigaDOS 1.3, SPARC Linux, SCO UNIX, the
+Apple Macintosh (both the MacsBug debugger and the rarer "Sad Mac"), and the
+Atari ST.
+.PP
+.SH OPTIONS
+.I bsod
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fIdelay\fP
+The delay between displaying one crash and another.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH X RESOURCES
+Notable X resources supported include the following, which control which
+hacks are displayed and which aren't.
+.BR doWindows ,
+.BR doNT ,
+.BR doAmiga ,
+.BR doMac ,
+.BR doMacsBug ,
+.BR doSCO ,
+.BR doAtari ,
+and
+.BR doSparcLinux .
+Each of these is a Boolean resource, they all default to true, except for
+doSparcLinux and doAtari, which are turned off by default, because they're
+really not all that interesting looking unless you're a fan of those systems.
+There aren't command-line options for these, so to change them, you'll need
+to add entries to your .Xdefaults file, or use the -xrm option.
+For example, to tell bsod not to show the NT crash:
+.EX
+bsod -xrm '*doNT: false'
+.EE
+.SH BUGS
+Unlike the systems that the images are borrowed from,
+.I bsod
+does not require a reboot after running.
+.PP
+.I bsod
+should also emulate more systems, but systems with interesting crash
+graphics are not as common as one might hope.
+
+One I'd really like to see is a Unix system getting a kernel panic, 
+rebooting, and running
+.BR fsck (8).

+/*
+ * I got my original inspiration for this by looking at the bottom of a 
+ * frying pan while something was cooking and watching the little bubbles
+ * coming off the bottom of the pan as the oil was boiling joining together
+ * to form bigger bubbles and finally to *pop* and disappear.  I had some
+ * time on my hands so I wrote this little xscreensaver module to imitate
+ * it.  Now that it's done it reminds me more of the bubbles you get in
+ * a glass of fizzy soft drink.....
+ *
+ * The problem seemed to be that the position/size etc. of all the bubbles
+ * on the screen had to be remembered and searched through to find when
+ * bubbles hit each other and combined.  To do this more efficiently, the
+ * window/screen is divided up into a square mesh of side length mesh_length
+ * and separate lists of bubbles contained in each cell of the mesh are
+ * kept.  Only the cells in the immediate vicinity of the bubble in question
+ * are searched.  This should make things more efficient although the whole
+ * thing seems to use up too much CPU, but then I'm using an ancient PC so
+ * perhaps it's not surprising .
+ * (Six months after I wrote the above I now have a Pentium with PCI graphics 
+ * and things are _much_ nicer.)

+.SH NAME
+bubbles - frying pan / soft drink simulation
+.SH SYNOPSIS
+.B bubbles
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-simple] [\-broken] [\-3D] [\-file filename] [\-directory directoryname]
+.SH DESCRIPTION
+\fIBubbles\fP sprays lots of little random bubbles all over the window which
+then grow until they reach their maximum size and go pop.  The inspiration
+for this was watching little globules of oil on the bottom of a frying pan
+and it also looks a little like bubbles in fizzy soft drink.  The default
+mode uses fancy ray-traced bubbles but there is also a mode which just draws 
+circles in case the default mode is too taxing on your hardware.
+.SH OPTIONS
+Depending on how your
+.I bubbles
+was compiled, it accepts the following options:
+.TP 8
+.B \-foreground
+Colour of circles if \fI\-simple\fP mode is selected.
+.TP 8
+.B \-background
+Colour of window background.
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay microseconds
+How much of a delay should be introduced between steps of the animation.
+Default 1, or about 1 microsecond.  Actually, this is the delay between each
+group of 15 new bubbles since such a delay between each step results in a
+very slow animation rate.
+.TP 8
+.B \-nodelay
+Same as \fI\-delay 0\fP.
+.TP 8
+.B \-simple
+Don't use the default fancy pixmap bubbles.  Just draw circles instead.
+This may give more bearable performance if your hardware wasn't made for
+this sort of thing.
+.TP 8
+.B \-broken
+Don't hide bubbles when they pop.  This was a bug during development
+but the results were actually quite attractive.  (This option is only
+available if you have the XPM library available and the imake generated
+Makefile has defined HAVE_XPM).
+.TP 8
+.B \-3D
+Normally, the simulation is done completely in two dimensions.  When a
+bubble swallows up another bubble, the areas of each are added to get
+the area of the resulting bubble.  This option changes the algorithm
+to instead add volume (imagining each to be a sphere in 3D space).  The
+whole thing looks more realistic but I find it attracts attention to
+the flickering of each bubble as they are move and are redrawn.  Your
+mileage may vary.
+.TP 8
+.B \-file filename
+Use the pixmap definitions in the given file, instead of the default (if
+one is compiled in).  This is ignored if \fI\-simple\fP is specified.  If
+the file is compressed (either with compress or gzip), it is decompressed
+before use.  (This option only works if you have XPM compiled into your
+binary and you have compiled with BUBBLES_IO set in bubbles.h.  This is
+\fBnot\fP the default).
+.TP 8
+.B \-directory directoryname
+Similar to \fI-file\fP except the file is taken randomly from the
+contents of the specified directory.  (Again, this option is only available
+if you have XPM and BUBBLES_IO was set when compiling.  See above).
+.TP 8
+.B \-quiet
+Don't print messages explaining why one or several command line options
+were ignored.  This is disabled by default.
+.SH NOTES
+If you find the pace of things too slow, remember that there is a delay
+even though you specify no \fI\-delay\fP option.  Try using \fI\-nodelay\fP
+although beware of the effects of irritation of other users if you're on a 
+shared system as you bleed their CPU time away.
+
+Some tools to assist in creation of new bubbles are included in the source
+distribution.  These can either be loaded with the \fI\-file\fP or
+\fI\-directory\fP options (if available) or they can be used in place
+of the distributed default bubble (bubble_default.c).
+You might like to copy these scripts to a permanent location and
+use them.  Read bubbles.README.
+
+Rendered bubbles are not supported on monochrome displays.  I'm not
+convinced that small bubbles, even dithered properly are going to look
+like anything more than a jumble of random dots.
+.SH BUGS
+There is a delay before something appears on the screen when using
+rendered bubbles.  The XPM library seems to take a \fBlong\fP time to make
+pixmaps out of raw data.  This can be irritating on slower systems.
+
+The movement of the bubbles looks jerky if an incomplete set of bubbles
+is used.  
+
+The hide/display algorithm could do with some work to avoid flickering
+when \fI\-nodelay\fP is set.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+
+   I've considered storing the data as (say) a binary tree within a 2d

+   storage space: searching the whole array on each iteration seems a
+   little inefficient.  However, the screensaver doesn't seem to take
+   up many cycles as it is: presumably the search is pretty quick
+   compared to the sleeps.  The current version uses less than 1% of
+   the CPU time of an AMD K6-233.  Many machines running X11 at this
+   point in time seem to be memory-limited, not CPU-limited.

+.TH XScreenSaver 1 "13-Nov-98" "X Version 11"
+.SH NAME
+critical - Draw a system showing self-organizing criticality
+.SH SYNOPSIS
+.B critical
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-delay \fIseconds\fP] [\-random \fIboolean\fP] [\-ncolors \fIint\fP] [\-offset \fIint\fP] 
+.SH DESCRIPTION
+The \fIcritical\fP program displays a self-organizing critical system
+that gradually emerges from chaos.
+
+\fIcritical\fP performs a simulation on a two-dimensional array of
+integers.  The array is initialized to random values.  On each
+iteration, it draws a line to the array position with the greatest
+value.  It then replaces that location and the eight neighboring
+locations with randomly-selected values.
+
+The lines are initially random, but over time a chaotic
+self-organizing system evolves: areas of the screen which happen to
+have lower values are less likely to be updated to new values, and so
+the line tends to avoid those areas.  Eventually, the histogram of
+changes approaches the power-law curve typical of such systems.
+
+The simplest documented self-organizing system is the one-dimensional
+equivalent of \fIcritical\fP.
+
+I heard about this algorithm second-hand: apparently there was an
+article in \fIScientific American\fP describing it sometime in 1997.
+.SH OPTIONS
+.I critical
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fIusecs\fP
+Number of microseconds to wait after drawing each line.
+.TP 8
+.B \-random \fIboolean\fP
+Whether to use randomly selected colours rather than a cycle around
+the colour wheel.
+.TP 8
+.B \-offset \fIinteger\fP
+The maximum random radius increment to use.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be allocated in the color ramp (note that this
+value interacts with \fIoffset\fP.)
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ *
+ * A moving polygon-mode. The polygons obey 2D-planegroup symmetry.
+ *
+ * The groupings of the cells fall in 3 categories:
+ *   oblique groups 1 and 2 where the angle gamma ranges from 60 to 120 degrees
+ *   square groups 3 through 11 where the angle gamma is 90 degrees
+ *   hexagonal groups 12 through 17 where the angle gamma is 120 degrees
+ *
+ * Revision History:
+ * 03-Dec-98: Random inversion of y-axis included to simulate hexagonal groups
+ *             with an angle of 60 degrees.
+ * 10-Sep-98: new colour scheme
+ * 24-Feb-98: added option centre which turns on/off forcing the centre of
+ *              the screen to be used
+ *            added option maxsize which forces the dimensions to be chasen
+ *              in such ua way that the largest possible part of the screen is
+ *              used 
+ *            When only one unit cell is drawn, it is chosen at random
+ * 18-Feb-98: added support for negative numbers with -nx and -ny meaning
+ *            "random" choice with given maximum
+ *            added +/-grid option. If -cell is specified this option
+ *            determines if one or all unit cells are drawn.
+ *            -batchcount is now a parameter for all the objects on the screen
+ *            instead of the number of "unique" objects
+ *            The maximum size of the objects now scales with the part
+ *            of the screen used.
+ *            fixed "size" problem. Now very small non-vissable objects
+ *            are not allowed
+ * 13-Feb-98: randomized the unit cell size
+ *            runtime options -/+cell (turn on/off unit cell drawing)
+ *             -nx num (number of translational symmetries in x-direction
+ *             -ny num (idem y-direction but ignored for square and
+ *               hexagonal space groups
+ *               i.e. try xlock -mode crystal -nx 3 -ny 2
+ *            Fullrandom overrules the -/+cell option.
+ * 05-Feb-98: Revision + bug repairs
+ *            shows unit cell
+ *            use part of the screen for unit cell
+ *            in hexagonal and square groups a&b axis forced to be equal
+ *            cell angle for oblique groups randomly chosen between 60 and 120
+ *   bugs solved: planegroups with cell angles <> 90.0 now work properly
+ * 19-Sep-97: Added remaining hexagonal groups
+ * 12-Jun-97: Created

+.TH XScreenSaver 1 "05-Apr-1999" "X Version 11"
+.SH NAME
+decayscreen - make a screen meltdown.
+.SH SYNOPSIS
+.B decayscreen
+[\-display \fIhost:display.screen\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-delay \fIusecs\fP] [\-mode \fImode\fP]
+.SH DESCRIPTION
+The \fIdecayscreen\fP program creates a melting effect by randomly
+shifting rectangles around the screen.
+.SH OPTIONS
+.I decayscreen
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fImicroseconds\fP
+Slow it down.
+.TP 8
+.B \-mode \fImode\fP
+The direction in which the image should tend to slide.  Legal values are
+\fIrandom\fP (meaning pick one), \fIup\fP, \fIleft\fP, \fIright\fP, 
+\fIdown\fP, \fIupleft\fP, \fIdownleft\fP, \fIupright\fP, \fIdownright\fP, 
+\fIshuffle\fP (meaning perfer no particular direction), \fIin\fP (meaning
+move things toward the center), \fIout\fP (meaning move things away
+from the center), \fImelt\fP (meaning melt straight downward), and \fIstretch\fP 
+(meaning stretch the screen downward).
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead.  The following resources control that.
+.PP
+.TP 8
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image, 
+between 0.0 and 1.0.  Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first.  If unspecified, 
+the default camera (from videopanel(1)) will be checked first.  After that, all
+other available video input devices will be checked in order.  
+
+The first one which produces a non-black image will be used.  If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image.  This defaults to 2.2.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.

+.TH XScreenSaver 1 "27-Apr-97" "X Version 11"
+.SH NAME
+deco - draw tacky 70s basement wall panelling
+.SH SYNOPSIS
+.B deco
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-delay \fIseconds\fP] [\-max\-depth \fIint\fP] [\-min\-width \fIint\fP] [\-min\-height \fIint\fP] [\-cycle] [\-no\-cycle] [\-cycle\-delay]
+.SH DESCRIPTION
+The \fIdeco\fP program subdivides and colors rectangles randomly.
+It looks kind of like Brady-Bunch-era rec-room wall paneling.
+(Raven says: "this screensaver is ugly enough to peel paint.")
+.SH OPTIONS
+.I deco
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fIseconds\fP
+How long to wait before starting over.  Default 5 seconds.
+.TP 8
+.B \-max\-depth \fIinteger\fP
+How deep to subdivide.  Default 12.
+Default 8.
+.TP 8
+.B \-min-width \fIinteger\fP
+.B \-min-height \fIinteger\fP
+The size of the smallest rectangle to draw.  Default 20x20.
+.TP 8
+.B \-cycle
+.TP 8
+.B \-no\-cycle
+Whether to do color cycling.  Default False.
+.TP 8
+.B \-cycle\-delay \fIusecs\fP
+If color cycling, how often to change the colors.  Default 1000000,
+or 1 second.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+drift - draws drifting recursive fractal cosmic flames
+.SH SYNOPSIS
+.B drift
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-count \fIinteger\fP] [\-grow] [\-no\-grow] [\-liss] [\-no\-liss]
+
+.SH DESCRIPTION
+The \fIdrift\fP program draws drifting recursive fractal cosmic flames
+.SH OPTIONS
+.I drift
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors used cycle through the hue, making N stops around
+the color wheel.
+.TP 8
+.B \-count \fIinteger\fP
+
+.TP 8
+.B \-grow
+.TP 8
+.B \-no\-grow
+Whether fractals should grow; otherwise, they are animated.
+
+.TP 8
+.B \-liss
+.TP 8
+.B \-no\-liss
+Whether we should use lissojous figures to get points.
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+[\-display \fIhost:display.screen\fP] [\-root] [\-window] [\-mono] [\-install] [\-noinstall] [\-visual \fIviz\fP] [\-colors \fIN\fP] [\-foreground \fIname\fP] [\-color\-shift \fIN\fP] [\-delay \fImicroseconds\fP] [\-holdtime \fIseconds\fP] [\-linewidth \fIN\fP] [\-min_circles \fIN\fP] [\-max_circles \fIN\fP] [\-min_speed \fInumber\fP] [\-max_speed \fInumber\fP] [\-harmonics \fIN\fP] [\-timestep \fInumber\fP] [\-divisor_poisson \fIprobability\fP] [\-size_factor_min \fInumber\fP] [\-size_factor_max \fInumber\fP]
+.SH DESCRIPTION
+The epicycle program draws the path traced out by a point on the edge
+of a circle.  That circle rotates around a point on the rim of another
+circle, and so on, several times.  The random curves produced can be
+simple or complex, convex or concave, but they are always closed
+curves (they never go in indefinitely).
+
+You can configure both the way the curves are drawn and the way in
+which the random sequence of circles is generated, either with
+command-line options or X resources.
+.SH OPTIONS
+.TP 8
+.B \-display \fIhost:display.screen\fP
+Specifies which X display we should use (see the section DISPLAY NAMES in
+.BR X (1)
+for more information about this option).
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-mono
+If on a color display, pretend we're on a monochrome display.
+If we're on a mono display, we have no choice.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-noinstall
+Don't install a private colormap for the window.
+.TP 8
+.B \-visual \fIviz\fP
+Specify which visual to use.  Legal values are the name of a visual
+class, or the id number (decimal or hex) of a specific visual.
+Possible choices include
+
+.RS
+default, best, mono, monochrome, gray, grey, color, staticgray, staticcolor, 
+truecolor, grayscale, greyscale, pseudocolor, directcolor, \fInumber\fP
+
+If a decimal or hexadecimal number is used, 
+.BR XGetVisualInfo (3X)
+is consulted to obtain the required visual.
+.RE
+.TP 8
+.B \-colors \fIN\fP
+How many colors should be used (if possible).  The colors are chosen
+randomly.
+.TP 8
+.B \-foreground \fIname\fP
+With 
+.BR \-mono ,
+this option selects the foreground colour.   
+.TP 8
+.B \-delay \fImicroseconds\fP
+Specifies the delay between drawing successive line segments of the
+path.   If you do not specify 
+.BR -sync ,
+some X servers may batch up several drawing operations together,
+producing a less smooth effect.   This is more likely to happen 
+in monochrome mode (on monochrome servers or when 
+.B \-mono 
+is specified).
+.TP 8
+.B \-holdtime \fIseconds\fP
+When the figure is complete, 
+.I epicycle
+pauses this number of seconds.
+.TP 8
+.B \-linewidth \fIN\fP
+Width in pixels of the body's track.   Specifying values greater than
+one may cause slower drawing.   The fastest value is usually zero,
+meaning one pixel.   
+.TP 8
+.B \-min_circles \fIN\fP
+Smallest number of epicycles in the figure.
+.TP 8
+.B \-max_circles \fIN\fP
+Largest number of epicycles in the figure.
+.TP 8
+.B \-min_speed \fInumber\fP
+Smallest possible value for the base speed of revolution of the
+epicycles.  The actual speeds of the epicycles vary from this down
+to
+.IB "min_speed / harmonics" .
+.TP 8
+.B \-max_speed \fInumber\fP
+Smallest possible value for the base speed of revolution of the 
+epicycles.
+.TP 8
+.B \-harmonics \fIN\fP
+Number of possible harmonics; the larger this value is, the greater
+the possible variety of possible speeds of epicycle.
+.TP 8
+.B \-timestep \fInumber\fP
+Decreasing this value will reduce the distance the body moves for
+each line segment, possibly producing a smoother figure.  Increasing
+it may produce faster results.  
+.TP 8
+.B \-divisor_poisson \fIprobability\fP
+Each epicycle rotates at a rate which is a factor of the base speed.
+The speed of each epicycle is the base speed divided by some integer
+between 1 and the value of the 
+.B \-harmonics 
+option.  This integer is decided by starting at 1 and tossing 
+a biased coin.  For each consecutive head, the value is incremented by
+one.  The integer will not be incremented above the value of the 
+.B \-harmonics
+option.  The argument of this option decides the bias of the coin; it
+is the probability that that coin will produce a head at any given toss.
+.TP 8
+.B \-size_factor_min \fInumber\fP
+Epicycles are always at least this factor smaller than their
+parents.  
+.TP 8
+.B \-size_factor_max \fInumber\fP
+Epicycles are never more than this factor smaller than their parents.

+.EE
+Before the drawing of the figure is begun, a preliminary calculation
+of the path is done in order to scale the radii of the epicycles so
+as to fit the figure on the screen or window.  For the sake of speed,
+This calculation is done with a larger timestep than the actual
+drawing.  The time-step used is the value of the
+.B \-timestep 
+option multiplied by the timestepCoarseFactor resource.  The default
+value of 1 will almost always work fast enough and so this resource
+is not available as a command-line option.
+.SH USER INTERFACE
+The program runs mostly without user interaction.  When running on the
+root window, no input is accepted.  When running in its own window,
+the program will exit if mouse button 3 is pressed.  If any other
+mouse button is pressed, the current figure will be abandoned and
+another will be started.
+.SH HISTORY
+The geometry of epicycles was perfected by Hipparchus of Rhodes at
+some time around 125 B.C., 185 years after the birth of Aristarchus of
+Samos, the inventor of the heliocentric universe model.  Hipparchus
+applied epicycles to the Sun and the Moon.  Ptolemy of Alexandria went
+on to apply them to what was then the known universe, at around 150
+A.D.  Copernicus went on to apply them to the heliocentric model at
+the beginning of the sixteenth century.  Johannes Kepler discovered
+that the planets actually move in elliptical orbits in about 1602.
+The inverse-square law of gravity was suggested by Boulliau in 1645.
+Isaac Newton's 
+.I Principia Mathematica
+was published in 1687, and proved that Kepler's laws derived from
+Newtonian gravitation.
+.SH BUGS
+The colour selection is re-done for every figure.  This may 
+generate too much network traffic for this program to work well 
+over slow or long links.

+.TH XScreenSaver 1 "24-May-97" "X Version 11"
+.SH NAME
+flag - draws a waving flag, containing text or an image
+.SH SYNOPSIS
+.B flag
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-cycles \fIinteger\fP] [\-size \fIinteger\fP] [\-text \fIstring\fP] [\-font \fIfont\fP] [\-bitmap \fIxbm-file\fP]
+
+.SH DESCRIPTION
+The \fIflag\fP program draws a waving flag that contains text or a bitmap.
+.SH OPTIONS
+.I flag
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+.TP 8
+.B \-cycles \fIinteger\fP
+
+.TP 8
+.B \-count \fIinteger\fP
+
+.TP 8
+.B \-size \fIinteger\fP
+How large the pixels in the flag should be, from 1 to 8.
+If this is a negative number, the pixel size is chosen randomly
+from the range 1 to -size.  Default -7.
+.TP 8
+.B \-text \fItext\fP
+The text to display in the flag.  Multiple lines of text are allowed;
+the lines will be displayed centered atop one another.  Default: none.
+If the text is the magic string \fI"(default)"\fP, then the text used 
+will be the local machine name; a newline; and the local OS version.
+.TP 8
+.B \-bitmap \fIxbm-file\fP
+The bitmap to display in the flag; this must be an XBM file (color XPMs
+are not allowed.)  Default: none.  If the bitmap is the magic 
+string \fI"(default)"\fP, then the bitmap used will be a charming 
+little picture of J. R. "Bob" Dobbs.
+
+If neither \fI\-text\fP nor \fI\-bitmap\fP are specified, then either
+the builtin text or the builtin bitmap will be chosen randomly.
+.TP 8
+.B \-font \fIfont\fP
+The font in which to draw the text; the default is
+"-*-helvetica-bold-r-*-240-*".
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-colors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+.TP 8
+.B \-iterations \fIinteger\fP
+How many fractals to generate.  Default 25.

+ *
+ * "flow" shows a variety of continuous phase-space flows around strange
+ * attractors.  It includes the well-known Lorentz mask (the "Butterfly"
+ * of chaos fame), two forms of Rossler's "Folded Band" and Poincare'
+ * sections of the "Birkhoff Bagel" and Duffing's forced occilator.
+ *
+ * Revision History:
+ * 31-Nov-98: [TDA] Added Duffing  (what a strange day that was :) DAB)
+ *   Duffing's forced oscillator has been added to the formula list and
+ *   the parameters section has been updated to display it in Poincare'
+ *   section.
+ * 30-Nov-98: [TDA] Added travelling perspective option
+ *   A more exciting point-of-view has been added to all autonomous flows.
+ *   This views the flow as seen by a particle moving with the flow.  In the
+ *   metaphor of the original code, I've attached a camera to one of the
+ *   trained bees!
+ * 30-Nov-98: [TDA] Much code cleanup.
+ * 09-Apr-97: [TDA] Ported to xlockmore-4

+This directory contains various graphics hacks that requre OpenGL.  These are
+independent from the xscreensaver program (in the ../../driver/ directory)
+but some of them use the utility functions found in the ../../utils/ directory.
+
+If you have compilation problems, check the parameters in ../../config.h.
+
+If you're looking for a free implementation of the OpenGL library, 
+check out <http://www.mesa3d.org/>.  For general OpenGL info, see

+ * REVISION HISTORY:
+ * 
+ * David A. Bagley - 98/06/17 : Add whalespeed option. Global options to
+ *                              initialize local variables are now:
+ *                              XLock.atlantis.cycles: 100      ! SharkSpeed
+ *                              XLock.atlantis.batchcount: 4    ! SharkNum
+ *                              XLock.atlantis.whalespeed: 250  ! WhaleSpeed
+ *                              XLock.atlantis.size: 6000       ! SharkSize
+ *                              Add random direction for whales/dolphins
+ * 
+ * E.Lassauge - 98/06/16: Use the following global options to initialize
+ *                        local variables :
+ *                              XLock.atlantis.delay: 100       ! SharkSpeed
+ *                              XLock.atlantis.batchcount: 4    ! SharkNum
+ *                              XLock.atlantis.cycles: 250      ! WhaleSpeed
+ *                              XLock.atlantis.size: 6000       ! SharkSize
+ *                        Add support for -/+ wireframe (t'was so easy to do!)
+ *
+ * TODO : 
+ *        - add a sort of background image or random bg color
+ *        - better handling of sizes and speeds
+ *        - test standalone and module modes
+ *        - purify it (!)

+ * Revision History:
+ * 01-Jan-98: Mode separated from escher and renamed
+ * 08-Jun-97: New scene implemented: "Impossible Cage" based in a M.C. Escher's
+ *            painting with the same name (quite similar). The first GL mode
+ *            to use texture mapping.
+ *            The "Impossible Cage" scene doesn't use DEPTH BUFFER, the 
+ *            wood planks are drawn consistently using GL_CULL_FACE, and
+ *            the painter's algorithm is used to sort the planks.
+ *            Marcelo F. Vianna.
+ * 07-Jun-97: Speed ups in Moebius Strip using GL_CULL_FACE.
+ *            Marcelo F. Vianna.
+ * 03-Jun-97: Initial Release (Only one scene: "Moebius Strip")
+ *            The Moebius Strip scene was inspirated in a M.C. Escher's
+ *            painting named Moebius Strip II in wich ants walk across a
+ *            Moebius Strip path, sometimes meeting each other and sometimes
+ *            being in "opposite faces" (note that the moebius strip has
+ *            only one face and one edge).
+ *            Marcelo F. Vianna.

+ * Texture mapping is only available on RGBA contexts, Mono and color index
+ * visuals DO NOT support texture mapping in OpenGL.
+ *
+ * BUT Mesa do implements RGBA contexts in pseudo color visuals, so texture
+ * mapping shuld work on PseudoColor, DirectColor, TrueColor using Mesa. Mono
+ * is not officially supported for both OpenGL and Mesa, but seems to not crash
+ * Mesa.
+ *
+ * In real OpenGL, PseudoColor DO NOT support texture map (as far as I know).

+ * Revision History:
+ * 9-Oct-98:  dek@cgl.ucsf.edu  Added stars.
+ *
+ * 8-Oct-98:  jwz@jwz.org   Made the 512x512x1 xearth image be built in.
+ *                          Made it possible to load XPM or XBM files.
+ *                          Made the planet bounce and roll around.
+ *
+ * 8-Oct-98: Released initial version of "glplanet"
+ * (David Konerding, dek@cgl.ucsf.edu)
+ *
+ * BUGS:
+ * -bounce is broken
+ * 
+ *   For even more spectacular results, grab the images from the "SSysten"
+ *   package (http://www.msu.edu/user/kamelkev/) and do this:

+/* Animates Lemarchand's Box, the Lament Configuration.  By jwz, 25-Jul-98.
+
+   TODO:
+
+     *  The "gold" color isn't quite right; it looks more like "yellow" than
+        "gold" to me.
+
+     *  For some reason, the interior surfaces are shinier than the exterior
+        surfaces.  I don't understand why, but this should be remedied.
+
+     *  Perhaps use a slightly-bumpy or oily texture for the interior surfaces?
+
+     *  Some of the edges don't line up perfectly (since the images are not
+        perfectly symetrical.)  Something should be done about this; either
+        making the edges overlap slightly (instead of leaving gaps) or fixing
+        the images so that the edges may be symmetrical.
+
+     *  I want the gold leaf to seem to be raised up from the surface, but I
+        think this isn't possible with OpenGL.  Supposedly, OpenGL only 
+        supports Gouraud shading (interpolating edge normals from face normals,
+        and shading smoothly) but bump-maps only work with Phong shading
+        (computing a normal for each rendered pixel.)
+
+     *  As far as I can tell, OpenGL doesn't do shadows.  As a result, the
+        forward-facing interior walls are drawn bright, not dark.  If it was
+        casting shadows properly, it wouldn't matter so much that the edges
+        don't quite line up, because the lines would be black, and thus not
+        visible.  But the edges don't match up, and so the bright interior
+        faces show through, and that sucks.
+
+       But apparently there are tricky ways around this:
+       http://reality.sgi.com/opengl/tips/rts/
+       I think these techniques require GLUT, however, which isn't 
+       (currently) required by any other xscreensaver hacks.
+
+     *  There should be strange lighting effects playing across the surface:
+        electric sparks, or little glittery blobs of light.  
+        http://reality.sgi.com/opengl/tips/lensflare/ might provide guidance.
+
+     *  Need to add some more modes, to effect the transition from the cube
+        shapes to the "spike" or "leviathan" shapes.  I have extensive notes
+        on how these transformations occur, but unfortunately, due to camera
+        trickery, the transitions require dematerializations which do not
+        preserve object volume.  But I suppose that's allowed, in
+        non-Euclidian or hyperdimensional spaces (since the extra mass could
+        simply be rotated along the axis to which one cannot point.)
+
+        The other hard thing about this is that the "leviathan" shapes contain
+        a much larger number of facets, and I modelled this whole thing by 
+        hand, since I don't have any 3d-object-editing tools that I know how
+        to use (or that look like they would take any less than several months
+        to become even marginally proficient with...)
+
+     *  Perhaps there should be a table top, on which it casts a shadow?
+        And then multiple light sources (for multiple shadows)?
+
+     *  Needs music.  ("Hellraiser Themes" by Coil: TORSO CD161; also
+        duplicated on the "Unnatural History 2" compilation, WORLN M04699.)
+
+     *  I'm not totally happy with the spinning motion; I like the
+        acceleration and deceleration, but it often feels like it's going too
+        fast, or not naturally enough, or something.
+
+     *  However, the motion is better than that used by gears, superquadrics,
+        etc.; so maybe I should make them all share the same motion code.

+.SH NAME
+lament - animates the Lament Configuration
+.SH SYNOPSIS
+.B lament
+[\-display \fIhost:display.screen\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP] [\-texture] [\-no\-texture] [\-wireframe]
+.SH DESCRIPTION
+The \fIlament\fP program draws an animation of a particular puzzle box
+repeatedly solving itself.
+.SH OPTIONS
+.I lament
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-texture
+Use texture maps.  This is the default.
+.TP 8
+.B \-no\-texture
+Do not use texture maps.  This is boring and wrong.
+.TP 8
+.B \-wireframe
+Only draw outlines.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH BUGS
+This hack is glacially slow on machines lacking hardware texture support.
+
+Occasionally opens doors, admitting theologians of the Order of the Gash.

+ * 
+ * This mode shows some interesting scenes that are impossible OR very
+ * wierd to build in the real universe. Much of the scenes are inspirated
+ * on Mauritz Cornelis Escher's works which derivated the mode's name.
+ * M.C. Escher (1898-1972) was a dutch artist and many people prefer to
+ * say he was a mathematician.
+ *

+ * OpenGL at home.

+ * Marcelo F. Vianna (Jun-01-1997)
+ *
+ * Revision History:
+ * 01-Jan-98: Mode separated from escher and renamed
+ * 08-Jun-97: New scene implemented: "Impossible Cage" based in a M.C. Escher's
+ *            painting with the same name (quite similar). The first GL mode
+ *            to use texture mapping.
+ *            The "Impossible Cage" scene doesn't use DEPTH BUFFER, the 
+ *            wood planks are drawn consistently using GL_CULL_FACE, and
+ *            the painter's algorithm is used to sort the planks.
+ *            Marcelo F. Vianna.
+ * 07-Jun-97: Speed ups in Moebius Strip using GL_CULL_FACE.
+ *            Marcelo F. Vianna.
+ * 03-Jun-97: Initial Release (Only one scene: "Moebius Strip")
+ *            The Moebius Strip scene was inspirated in a M.C. Escher's
+ *            painting named Moebius Strip II in wich ants walk across a
+ *            Moebius Strip path, sometimes meeting each other and sometimes
+ *            being in "opposite faces" (note that the moebius strip has
+ *            only one face and one edge).
+ *            Marcelo F. Vianna.
+ *
+ */
+
+/*-
+ * Texture mapping is only available on RGBA contexts, Mono and color index
+ * visuals DO NOT support texture mapping in OpenGL.
+ *
+ * BUT Mesa do implements RGBA contexts in pseudo color visuals, so texture
+ * mapping shuld work on PseudoColor, DirectColor, TrueColor using Mesa. Mono
+ * is not officially supported for both OpenGL and Mesa, but seems to not crash
+ * Mesa.
+ *
+ * In real OpenGL, PseudoColor DO NOT support texture map (as far as I know).

+
+ * Revision History:
+ * 4-Apr-1999:  dek@cgl.ucsf.edu  Created module "pulsar"
+ * 27-Apr-1999:  dek@cgl.ucsf.edu  Submitted module "pulsar"
+ * 4-May-1999:  jwz@jwz.org  Added module "pulsar"
+ * 4-May-1999:  dek@cgl.ucsf.edu  Submitted module "pulsar" updates
+ *
+ * Notes:
+ * The pulsar screensaver draws a number of rotating, pulsing rectangles
+ * on your screen.  Depending on the options you choose, you can set a number
+ * of interesting OpenGL parameters, including alpha blending, depth testing, fog,
+ * lighting, texturing, mipmapping, bilinear filtering, and line antialiasing.  
+ * Additionally, there is a "frames per second" meter which gives an estimate of
+ * the speed of your graphics card.  
+ *
+ * Example command-line switches:
+ * Only draw a single quad, and don't fill it (boring but fast)
+ * pulsar -wire -quads 1 -fps
+ *
+ * Only try this with hardware graphics acceleration (PPro 200 w/ a Voodoo 2 runs great)
+ * pulsar -quads 10 -texture -mipmap -texture_quality -light -fog -fps
+ *

+ * Marcelo F. Vianna (Jul-31-1997)
+ *
+ * Revision History:
+ * 26-Sep-98: Added some more movement (the cube do not stays in the screen
+ *            center anymore. Also fixed the scale problem imediatelly after
+ *            shuffling when the puzzle is solved.
+ * 08-Aug-97: Now has some internals from xrubik by David Bagley
+ *            This should make it easier to add features.
+ * 02-Aug-97: Now behaves more like puzzle.c: first show the cube being
+ *            shuffled and then being solved. A mode specific option was added:
+ *            "+/-hideshuffling" to provide the original behavior (in which
+ *            only the solution is shown).
+ *            The color labels corners are now rounded.
+ *            Optimized the cubit() routine using glLists.
+ * 01-Aug-97: Shuffling now avoids movements that undoes the previous movement
+ *            and three consecutive identical moves (which is pretty stupid).
+ *            improved the "cycles" option in replacement of David's hack,
+ *            now rp->anglestep is a GLfloat, so this option selects the
+ *            "exact" number of frames that a rotation (movement) takes to
+ *            complete.
+ * 30-Jul-97: Initial release, there is no algorithm to solve the puzzle,
+ *            instead, it randomly shuffle the cube and then make the
+ *            movements in the reverse order.
+ *            The mode was written in 1 day (I got sick and had the day off).
+ *            There was not much to do since I could not leave home... :)

+ * 28-Mar-97: Added size support.
+ * 22-Mar-97: Updated to use glX interface instead of xmesa one.

+ *              my own.  Submitted for inclusion in xlockmore.

+ * The sproingies have six "real" frames, (s1_1 to s1_6) that show a
+ * sproingie jumping off a block, headed down and to the right.  But
+ * the program thinks of sproingies as having twelve "virtual" frames,
+ * with the latter six being copies of the first, only lowered and
+ * rotated by 90 degrees (jumping to the left).  So after going
+ * through 12 frames, a sproingie has gone down two rows but not
+ * moved horizontally. 
+ *
+ * To have the sproingies randomly choose left/right jumps at each
+ * block, the program should go back to thinking of only 6 frames,
+ * and jumping down only one row when it is done.  Then it can pick a
+ * direction for the next row.
+ *
+ * (Falling off the end might not be so bad either.  :) )

+ *
+ * Superquadrics were invented by Dr. Alan Barr of Caltech University.
+ * They were first published in "Computer Graphics and Applications",
+ * volume 1, number 1, 1981, in the article "Superquadrics and Angle-
+ * Preserving Transformations."  Dr. Barr based the Superquadrics on
+ * Piet Hein's "super ellipses."  Super ellipses are like 2D ellipses,
+ * except that the formula includes an exponent, raising its X and Y
+ * values to a (fractional) power, and allowing them to gradually
+ * change from round to square edges.  Superquadrics extend this
+ * idea into 3 dimensions, using two exponents to modify a
+ * quadric surface in a similar fashion.
+ *
+ * Revision History:
+ * 30-Mar-97: Turned into a module for xlockmore 4.02 alpha.  The code
+ *    is almost unrecognizable now from the first revision, except for
+ *    a few remaining two-letter variable names.  I still don't have
+ *    the normal vectors working right (I wrote the buggy normal vector
+ *    code myself, can you tell?)
+ * 07-Jan-97: A legend reborn; Superquadrics make an appearance as a
+ *    real OpenGL program written in C.  I can even render them with
+ *    proper lighting and specular highlights.  Gee, they look almost
+ *    as good now as the original color plates of them that my uncle
+ *    showed me as a child in 1981.  I don't know what computer hardware
+ *    he was using at the time, but it's taken a couple decades for the
+ *    PC clone hardware to catch up to it.
+ * 05-Jan-97: After almost a decade, Superquadrics had almost faded away
+ *    into the myths and folklore of all the things my brother and I played
+ *    with on computers when we were kids with too much time on our hands.
+ *    I had since gotten involved in Unix, OpenGL, and other things.
+ *    A sudden flash of inspiration caused me to dig out the old Pascal
+ *    source code, run it through p2c, and start ripping away the old
+ *    wireframe rendering code, to be replaced by OpenGL.
+ * Late 1989 or early 1990:  Around this time I did the Turbo Pascal
+ *    port of the Superquadrics.  Unfortunately, many of the original variable
+ *    names remained the same from the C= 64 original.  This was unfortunate
+ *    because BASIC on the c64 only allowed 2-letter, global variable names.
+ *    But the speed improvement over BASIC was very impressive at the time.
+ * Thanksgiving, 1987: Written.  My uncle Al, who invented Superquadrics some
+ *    years earlier, came to visit us.  I was a high school kid at the time,
+ *    with nothing more than a Commodore 64.  Somehow we wrote this program,
+ *    (he did the math obviously, I just coded it into BASIC for the c64).
+ *    Yeah, 320x200 resolution, colorless white wireframe, and half an hour
+ *    rendering time per superquadric.  PLOT x,y.  THOSE were the days.
+ *    In the following years I would port Superquadrics to AppleBASIC,
+ *    AmigaBASIC, and then Turbo Pascal for IBM clones.  5 minutes on a 286!
+ *    Talk about fast rendering!  But these days, when my Pentium 166 runs
+ *    the same program, the superquadric will already be waiting on the
+ *    screen before my monitor can change frequency from text to graphics
+ *    mode.  Can't time the number of minutes that way!  Darn ;)

+/* This is pretty compute-intensive, probably due to the large number of
+   polygon fills.  I tried introducing a scaling factor to make the spline
+   code emit fewer line segments, but that made the edges very rough.
+   However, tuning *maxVelocity, *elasticity and *delay can result in much
+   smoother looking animation.  I tuned these for a 1280x1024 Indy display,
+   but I don't know whether these values will be reasonable for a slower
+   machine...
+
+   The more planes the better -- SGIs have a 12-bit pseudocolor display
+   (4096 colormap cells) which is mostly useless, except for this program,
+   where it means you can have 11 or 12 mutually-transparent objects instead
+   of only 7 or 8.  But, if you are using the 12-bit visual, you should crank
+   down the velocity and elasticity, or server slowness will cause the
+   animation to look jerky (yes, it's sad but true, SGI's X server is
+   perceptibly slower when using plane masks on a 12-bit visual than on an
+   8-bit visual.)  Using -max-velocity 0.5 -elasticity 0.9 seems to work ok
+   on my Indy R5k with visual 0x27 and the bottom-of-the-line 24-bit graphics
+   board.
+
+   It might look better if each blob had an outline, which was a *slightly*
+   darker color than the center, to give them a bit more definition -- but
+   that would mean using two planes per blob.  (Or maybe allocating the
+   outline colors outside of the plane-space?  Then the outlines wouldn't be
+   transparent, but maybe that wouldn't be so noticeable?)
+
+   Oh, for an alpha channel... maybe I should rewrite this in GL.  Then the
+   blobs could have thickness, and curved edges with specular reflections...

+.TH XScreenSaver 1 "11-Jun-97" "X Version 11"
+.SH NAME
+goop - squishy transparent oil and bubble screenhack
+.SH SYNOPSIS
+.B goop
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-transparent] [\-non\-transparent] [\-additive] [\-subtractive] [\-xor] [\-no\-xor]
+.SH DESCRIPTION
+The \fIgoop\fP program draws a simulation of bubbles in layers of 
+overlapping multicolored translucent fluid.
+.SH OPTIONS
+.I goop
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-count \fIinteger\fP
+How many bubbles to draw per layer.  Default: random.
+.TP 8
+.B \-layers \fIinteger\fP
+How many layers to draw.  Default: random, based on screen depth.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 100000, or about 1/10th second.
+.TP 8
+.B \-transparent
+If \fI\-layers\fP is greater than 1, then each layer will be drawn in one
+color, and when they overlap, the colors will be mixed. This is the default.
+.TP 8
+.B \-non\-transparent
+Turns off \fI\-transparent\fP.
+.TP 8
+.B \-additive
+If \fI\-transparent\fP is specified, then this option means that the colors
+will be mixed using an additive color model, as if the blobs were projected
+light.  This is the default.
+.TP 8
+.B \-subtractive
+If \fI\-transparent\fP is specified, then this option means that the
+colors will be mixed using a subtractive color model, as if the blobs were
+translucent filters.
+.TP 8
+.B \-xor
+Draw with xor instead of the other color tricks.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+grav - draws a simple orbital simulation
+.SH SYNOPSIS
+.B grav
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-count \fIinteger\fP] [\-decay] [\-no\-decay] [\-trail] [\-no\-trail]
+
+.SH DESCRIPTION
+The \fIgrav\fP program draws a simple orbital simulation
+.SH OPTIONS
+.I grav
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors are chosen randomly.
+.TP 8
+.B \-count \fIinteger\fP
+Default 12.
+.TP 8
+.B \-decay
+.TP 8
+.B \-no-\decay
+Whether orbits should decay.
+
+.TP 8
+.B \-trail
+.TP 8
+.B \-no\-trail
+Whether the objects should leave trails behind them (makes it look vaguely
+like a cloud-chamber.
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "12-Jun-97" "X Version 11"
+.SH NAME
+halo - draw circular patterns
+.SH SYNOPSIS
+.B halo
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-count \fIint\fP] [\-delay \fIusecs\fP] [\-mode seuss | ramp | random ] [\-animate] [\-colors \fIinteger\fP] [\-cycle] [\-no\-cycle] [\-cycle\-delay \fIusecs\fP] 
+.SH DESCRIPTION
+The \fIhalo\fP program draws cool patterns based on circles.
+.SH OPTIONS
+.I halo
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-count \fIinteger\fP
+How many circles to draw.  Default 0, meaning random.
+.TP 8
+.B \-mode "seuss | ramp | random"
+In \fIseuss\fP mode, alternating striped curves will be drawn.
+
+In \fIramp\fP mode, a color ramp will be drawn.
+
+\fIrandom\fP means pick the mode randomly.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 100000, or about 0.1 second.
+.TP 8
+.B \-colors \fIinteger\fP
+How many colors to use.  Default 100.
+.TP 8
+.B \-animate
+If specified, then the centerpoints of the circles will bounce around.
+Otherwise, the circles will be drawn once, erased, and a new set of
+circles will be drawn.
+.TP 8
+.B \-cycle
+.TP 8
+.B \-no\-cycle
+Whether to do colormap cycling.  Default is to cycle.
+.TP 8
+.B \-cycle\-delay
+Number of microseconds between shifts of the colormap; default 100000,
+or 1/10th second.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "18-sep-97" "X Version 11"
+.SH NAME
+helix - draw helical string-art patterns
+.SH SYNOPSIS
+.B helix
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-erase\-speed \fIusecs\fP] [\-erase\-mode \fIinteger\fP] [\-delay \fIseconds\fP] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIhelix\fP program draws interesting patterns composed of line segments
+in random colors.
+.SH OPTIONS
+.I helix
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-erase\-speed \fIusecs\fP
+This controls the speed at which the screen will be erased. Lower numbers 
+erase faster.
+.TP 8
+.B \-erase\-mode \fIinteger\fP
+This sets the erase mode. Mode \-1 chooses a random mode each time. There
+are currently 6 modes defined (0\-5).
+.TP 8
+.B \-delay \fIseconds\fP
+This sets the number of seconds that the helix will be on the screen.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ *
+ * Revision History:
+ * Changes of David Bagley <bagleyd@bigfoot.com>
+ * 24-Jun-97: EJK and RR functions stolen from xmartin2.2
+ *            Ed Kubaitis <ejk@ux2.cso.uiuc.edu> ejk functions and xmartin 
+ *            Renaldo Recuerdo rr function, generalized exponent version
+ *              of the Barry Martin's square root function
+ * 10-May-97: jwz@jwz.org: ported from xlockmore 4.03a10 to be a 
+ *                       standalone program and thus usable with xscreensaver
+ *                       (I threw away my 1992 port and started over.)
+ * 27-Jul-95: added Peter de Jong's hop from Scientific American
+ *            July 87 p. 111.  Sometimes they are amazing but there are a
+ *            few duds (I did not see a pattern in the parameters).
+ * 29-Mar-95: changed name from hopalong to hop
+ * 09-Dec-94: added Barry Martin's sine hop
+ *
+ * (12-Aug-92: jwz@lucid.com: made xlock version run standalone.)
+ *
+ * Changes of Patrick J. Naughton
+ * 29-Oct-90: fix bad (int) cast.
+ * 29-Jul-90: support for multiple screens.
+ * 08-Jul-90: new timing and colors and new algorithm for fractals.
+ * 15-Dec-89: Fix for proper skipping of {White,Black}Pixel() in colors.
+ * 08-Oct-89: Fixed long standing typo bug in RandomInitHop();
+ *           Fixed bug in memory allocation in init_hop();
+ *           Moved seconds() to an extern.
+ *           Got rid of the % mod since .mod is slow on a sparc.
+ * 20-Sep-89: Lint.
+ * 31-Aug-88: Forked from xlock.c for modularity.
+ * 23-Mar-88: Coded HOPALONG routines from Scientific American Sept. 86 p. 14.
+ *            Hopalong was attributed to Barry Martin of Aston University
+ *            (Birmingham, England)

+.TH XScreenSaver 1 "10-May-97" "X Version 11"
+.SH NAME
+hopalong - draw real plane fractals
+.SH SYNOPSIS
+.B hopalong
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-cycles \fIinteger\fP] [\-count \fIinteger\fP] [\-jong] [\-no\-jong] [\-jong] [\-no\-sine]
+
+.SH DESCRIPTION
+The \fIhopalong\fP program generates real plane fractals as described in
+the September 1986 issue of Scientific American.
+.SH OPTIONS
+.I hopalong
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors used cycle through the hue, making N stops around
+the color wheel.
+.TP 8
+.B \-cycles \fIinteger\fP
+How long to run each batch.  Default 2500 pixels.
+.TP 8
+.B \-count \fIinteger\fP
+How many pixels should be drawn before a color change.  Default 1000.
+.TP 8
+.B \-jong \fIinteger\fP
+.TP 8
+.B \-no\-jong \fIinteger\fP
+Whether to use the Jong format (default is to choose randomly.)
+
+.TP 8
+.B \-sine \fIinteger\fP
+.TP 8
+.B \-no\-sine \fIinteger\fP
+Whether to use the Sine format (default is to choose randomly.)
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "6-dec-92" "X Version 11"
+.SH NAME
+hypercube - 2d projection of a 4d object
+.SH SYNOPSIS
+.B hypercube
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-color[0-7] \fIcolor\fP] [\-xy \fIfloat\fP] [\-xz \fIfloat\fP] [\-yz \fIfloat\fP] [\-xw \fIfloat\fP] [\-yw \fIfloat\fP] [\-zw \fIfloat\fP] [\-observer-z \fIint\fP] [\-delay \fIusecs\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIhypercube\fP program displays a wireframe projection of a hypercube
+which is rotating at user-specified rates around any or all of its four axes.
+.SH OPTIONS
+.I hypercube
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 100000, or about 1/10th second.
+.TP 8
+.B \-observer-z \fIint\fP
+How far away the observer is from the center of the cube (the cube is one
+unit per side.)  Default 5.
+.TP 8
+.B \-color0 \fIcolor\fP
+.TP 8
+.B \-color1 \fIcolor\fP
+.TP 8
+.B \-color2 \fIcolor\fP
+.TP 8
+.B \-color3 \fIcolor\fP
+.TP 8
+.B \-color4 \fIcolor\fP
+.TP 8
+.B \-color5 \fIcolor\fP
+.TP 8
+.B \-color6 \fIcolor\fP
+.TP 8
+.B \-color7 \fIcolor\fP
+The colors used to draw the line segments bordering the eight faces of
+the cube.  Some of the faces have only two of their border-lines drawn in
+the specified color, and some have all four.
+.TP 8
+.B \-xw \fIfloat\fP
+.TP 8
+.B \-xy \fIfloat\fP
+.TP 8
+.B \-xz \fIfloat\fP
+.TP 8
+.B \-yw \fIfloat\fP
+.TP 8
+.B \-yz \fIfloat\fP
+.TP 8
+.B \-zw \fIfloat\fP
+The amount that the cube should be rotated around the specified axis at
+each frame of the animation, expressed in radians.  These should be small
+floating-point values (less than 0.05 works best.)  Default: xy=0.01,
+xz=0.005, yw=0.01.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+ifs - draws spinning, colliding iterated-function-system images
+.SH SYNOPSIS
+.B ifs
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP]
+
+.SH DESCRIPTION
+The \fIifs\fP program draws spinning, colliding iterated-function-system images.
+.SH OPTIONS
+.I ifs
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors used cycle through the hue, making N stops around
+the color wheel.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+imsmap - generate fractal maps
+.SH SYNOPSIS
+.B imsmap
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIint\fP] [\-delay \fIseconds\fP] [\-iterations \fIint\fP] [\-mode h|s|v|random] [\-cycle] [\-no\-cycle]
+.SH DESCRIPTION
+The \fIimsmap\fP program generates map or cloud-like patterns.  It looks
+quite different in monochrome and color.
+.SH OPTIONS
+.I imsmap
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors to use.  Default 50.
+.TP 8
+.B \-delay \fIinteger\fP
+How long to delay between images.  Default 10 seconds.
+.TP 8
+.B \-iterations \fIinteger\fP
+A measure of the resolution of the resultant image, from 0 to 7.  Default 7.
+.TP 8
+.B \-mode [ hue | saturation | value | random ]
+The axis upon which colors should be interpolated between the foreground
+and background color.  Default random.  
+.TP 8
+.B \-cycle
+.TP 8
+.B \-no\-cycle
+Whether to do colormap cycling.  Default is to cycle.
+.TP 8
+.B \-cycle\-delay
+Number of microseconds between shifts of the colormap; default 100000,
+or 1/10th second.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * decaying sinusoidal waves, which extend spherically from their
+ * respective origins, move around the plane. a sort of interference
+ * between them is calculated and the resulting twodimensional wave
+ * height map is plotted in a grid, using softly changing colours.
+ *
+ * not physically (or in any sense) accurate, but fun to look at for 
+ * a while. you may tune the speed/resolution/interestingness tradeoff 
+ * with X resources, see below.

+ * TODO:
+ *
+ *    This really needs to be sped up.
+ *
+ *    I've tried making it use XPutPixel/XPutImage instead of XFillRectangle,
+ *    but that doesn't seem to help (it's the same speed at gridsize=1, and
+ *    it actually makes it slower at larger sizes.)
+ *
+ *    I played around with shared memory, but clearly I still don't know how
+ *    to use the XSHM extension properly, because it doesn't work yet.
+ *
+ *    Hannu had put in code to use the double-buffering extension, but that
+ *    code didn't work for me on Irix.  I don't think it would help anyway,
+ *    since it's not the swapping of frames that is the bottleneck (or a source
+ *    of visible flicker.)

+.TH XScreenSaver 1 "25-Nov-97" "X Version 11"
+.SH NAME
+jigsaw - permute the screen image like a jigsaw puzzle
+.SH SYNOPSIS
+.B jigsaw
+[\-display \fIhost:display.screen\fP] [\-background \fIcolor\fP] [\-delay \fIusecs\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIjigsaw\fP program takes an image of the screen, carves it up into
+a jigsaw puzzle, shuffles it, and then solves it.
+.SH OPTIONS
+.I jigsaw
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long to wait between shuffling pieces; default 700000, or 0.7 seconds.
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead.  The following resources control that.
+.PP
+.TP 8
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image, 
+between 0.0 and 1.0.  Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first.  If unspecified, 
+the default camera (from videopanel(1)) will be checked first.  After that, all
+other available video input devices will be checked in order.  
+
+The first one which produces a non-black image will be used.  If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image.  This defaults to 2.2.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * Revision History:
+ * 28-May-97: jwz@jwz.org: added interactive frobbing with the mouse.
+ * 10-May-97: jwz@jwz.org: turned into a standalone program.
+ * 02-Dec-95: snagged boilerplate from hop.c
+ *           used ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration 
+ *           to plot the julia set, and sinusoidially varied parameter for set 
+ *          and plotted parameter with a circle.
+ */
+
+/*-
+ * One thing to note is that batchcount is the *depth* of the search tree,
+ * so the number of points computed is 2^batchcount - 1.  I use 8 or 9
+ * on a dx266 and it looks okay.  The sinusoidal variation of the parameter
+ * might not be as interesting as it could, but it still gives an idea of
+ * the effect of the parameter.

+.TH XScreenSaver 1 "28-May-97" "X Version 11"
+.SH NAME
+julia - draws spinning, animating julia-set fractals
+.SH SYNOPSIS
+.B julia
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-cycles \fIinteger\fP] [\-count \fIinteger\fP] [\-mouse] [\-nomouse]
+
+.SH DESCRIPTION
+The \fIjulia\fP program draws spinning, animating julia-set fractals.
+
+It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration 
+to plot the julia set, and sinusoidially varied parameters for the set,
+and plots parameters with a circle.
+
+One thing to note is that count is the \fIdepth\fP of the search tree,
+so the number of points computed is (2^count)-1.  I use 8 or 9 on a
+dx266 and it looks okay.  The sinusoidal variation of the parameter
+might not be as interesting as it could, but it still gives an idea 
+of the effect of the parameter.
+
+.SH OPTIONS
+.I julia
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors used cycle through the hue, making N stops around
+the color wheel.
+.TP 8
+.B \-cycles \fIinteger\fP
+
+.TP 8
+.B \-count \fIinteger\fP
+
+.TP 8
+.B \-mouse
+.TP 8
+.B \-nomouse
+If \fI\-mouse\fP is specified, the control point of the Julia set will
+be derived from the position of the mouse in the window.  When the mouse
+is not in the window, the control point is chosen the normal way.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH SEE ALSO

+.SH NAME
+Kaleidescope - rotating line segments
+.SH SYNOPSIS
+.B kaleidescope
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP] [\-color_mode \fImono | nice | greedy\fP] [-nsegments \fIint\fP] [\-ntrails \fIint\fP] [\-local_rotation \fIint\fP] [\-global_rotation \fIint\fP] [\-delay \fIusecs\fP] [\-redmin \fIint\fP] [\-greenmin \fIint\fP] [\-bluemin \fIint\fP] [\-redrange \fIint\fP] [\-greenrange \fIint\fP] [\-bluerange \fIint\fP]
+.SH DESCRIPTION
+The \fIkaleidescope\fP program draws line segments in a symmetric pattern
+that evolves over time. 
+.SH OPTIONS
+.I kaleidescope
+accepts the following options:
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-color_mode "mono | nice | greedy"
+Specify how kaleidescope uses colors. Mono uses
+just the default foreground and background colors. Nice uses one
+color for each segment (specified by nsegments). Greedy uses (ntrails * nsegments) + 1  colors.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-nsegments integer
+The number of segments to draw. Default is 7.
+.TP 8
+.B \-ntrails integer
+The number of trails to draw. Default is 100.
+.TP 8
+.B \-local_rotation integer
+The rate at which segments rotate around their center. Default is -59.
+.TP 8
+.B \-global_rotation integer 
+The rate at which segments rotate around the center of the window.
+Default is 1. 
+.TP 8
+.B \-redmin, \-greenmin, \-bluemin, \-redrange, \-greenrange, \-bluerange
+All take an integer argument. When colors are randomly chosen, they 
+are chosen from the interval min to min plus range. The minimums default
+to 30000. The ranges default to 20000. 
+.TP 8
+.B \-delay microseconds
+How much of a delay should be introduced between steps of the animation.
+Default is 20000, or about 5 frames a second.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH DESCRIPTION
+The \fIlaser\fP program draws vaguely laser-like moving lines
+.SH OPTIONS
+.I laser
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors used cycle through the hue, making N stops around the color wheel.
+.TP 8
+.B \-cycles \fIinteger\fP
+Default 200.
+.TP 8
+.B \-count \fIinteger\fP
+Default 10.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * Revision History:
+ * 10-May-97: Compatible with xscreensaver
+ *
+ * The inspiration for this program, Lasp, was written by Adam B. Roach 
+ * in 1990, assisted by me, Caleb Cullen.  It was written first in C, then
+ * in assembly, and used pre-calculated data tables to graph lisajous
+ * figures on 386 machines and lower.  This version bears only superficial
+ * resemblances to the original Lasp.
+ *
+ * The `lissie' module's source code was studied as an example of how
+ * to incorporate a new module into xlock.  Resemblances to it are
+ * expected, but not intended to be plaigiaristic.

+ *                  The original idea, and the bilinear interpolation
+ *                  mathematics used, emerged in the head of the wise
+ *                  Glenn T. Lines.
+ *
+ *  MODIFICATIONS   june 1998 (shh)
+ *                    * Minor code cleanup.
+ *
+ *                  march 1997 (shh)
+ *                    * Added -mailfile option to allow checking for
+ *                      new mail while the screensaver is active.
+ *
+ *                  january 1997 (shh)
+ *                    * Some code reformatting.
+ *                    * Added possibility to use float arithmetic.
+ *                    * Added -figtype option.
+ *                    * Made color blue default.
+ *
+ *                  december 1995 (jwz)
+ *                    * Function headers converted from ANSI to K&R.
+ *                    * Added posibility for random number of steps, and
+ *                      made this the default.
+ *
+ *                  march 1995 (shh)
+ *                    * Converted from an MS-Windows program to X Window.

+ * Revision History:
+ * 18-Oct-98: Started creating a hexagon version, probably will not work
+ *            for a while since some work has to go into getting not
+ *            only the program to handle the hexagonal data but the loop
+ *            has to be "programmed" as well.  I suspect it should be easier
+ *            than the original since the loop will have six sides to
+ *            store its genes (data).
+ * 10-May-97: Compatible with xscreensaver
+ * 15-Nov-95: Coded from Chris Langton's Self-Reproduction in Cellular
+ *            Automata Physica 10D 135-144 1984
+ *            also used wire.c as a guide.

+ * From Steven Levy's Artificial Life
+ * Chris Langton's cellular automata "loops" reproduce in the spirit of life.
+ * Beginning from a single organism, the loops from a colony.  As the loops
+ * on the outer fringes reproduce, the inner loops -- blocked by their
+ * daughters -- can no longer produce offspring.  These dead progenitors
+ * provide a base for future generations' expansion, much like the formation
+ * of a coral reef.  This self-organizing behavior emerges spontaneously,
+ * from the bottom up -- a key characteristic of artificial life.

+/*-
+   Don't Panic  --  When the artificial life tries to leave its petri
+   dish (ie. the screen) it will (usually) die...
+   The loops are short of "real" life because a general purpose Turing
+   machine is not contained in the loop.  This is a simplification of
+   von Neumann and Codd's self-producing Turing machine.
+   The data spinning around could be viewed as both its DNA and its internal
+   clock.

+ * [ maze ] ...
+ *
+ * modified:  [ 6-28-98 ]  Zack Weinberg <zack@rabi.phys.columbia.edu>
+ *
+ *              Made the maze-solver somewhat more intelligent.  There are
+ *              three optimizations:
+ *
+ *              - Straight-line lookahead: the solver does not enter dead-end
+ *                corridors.  This is a win with all maze generators.
+ *
+ *              - First order direction choice: the solver knows where the
+ *                exit is in relation to itself, and will try paths leading in
+ *                that direction first. This is a major win on maze generator 1
+ *                which tends to offer direct routes to the exit.
+ *
+ *              - Dead region elimination: the solver already has a map of
+ *                all squares visited.  Whenever it starts to backtrack, it
+ *                consults this map and marks off all squares that cannot be
+ *                reached from the exit without crossing a square already
+ *                visited.  Those squares can never contribute to the path to
+ *                the exit, so it doesn't bother checking them.  This helps a
+ *                lot with maze generator 2 and somewhat less with generator 1.
+ *
+ *              Further improvements would require knowledge of the wall map
+ *              as well as the position of the exit and the squares visited.
+ *              I would consider that to be cheating.  Generator 0 makes
+ *              mazes which are remarkably difficult to solve mechanically --
+ *              even with these optimizations the solver generally must visit
+ *              at least two-thirds of the squares.  This is partially
+ *              because generator 0's mazes have longer paths to the exit.
+ *
+ * modified:  [ 4-10-97 ]  Johannes Keukelaar <johannes@nada.kth.se>
+ *              Added multiple maze creators. Robustified solver.
+ *              Added bridge option.
+ * modified:  [ 8-11-95 ] Ed James <james@mml.mmc.com>
+ *              added fill of dead-end box to solve_maze while loop.
+ * modified:  [ 3-7-93 ]  Jamie Zawinski <jwz@jwz.org>
+ *             added the XRoger logo, cleaned up resources, made
+ *             grid size a parameter.
+ * modified:  [ 3-3-93 ]  Jim Randell <jmr@mddjmr.fc.hp.com>
+ *             Added the colour stuff and integrated it with jwz's
+ *             screenhack stuff.  There's still some work that could
+ *             be done on this, particularly allowing a resource to
+ *             specify how big the squares are.

+.SH NAME
+maze \- an automated X11 demo repeatedly creating and solving a random maze
+.SH SYNOPSIS
+.B maze 
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP] [\-grid\-size \fIpixels\fP] [\-live\-color \fIcolor\fP] [\-dead\-color \fIcolor\fP] [\-solve\-delay \fIusecs\fP] [\-pre\-delay \fIusecs\fP] [\-post\-delay \fIusecs\fP] [\-generator \fIinteger\fP] [\-max\-length \fIinteger\fP] [\-bridge] [\-no\-bridge]
+.SH DESCRIPTION
+The \fImaze\fP program creates a "random" maze and then solves it with 
+graphical feedback. 
+.SH OPTIONS
+.I maze
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-grid\-size \fIpixels\fP
+The size of each block of the maze, in pixels; default is 0, meaning
+pick a random grid size.
+.TP 8
+.B \-live\-color \fIcolor\fP
+The color of the path.
+.TP 8
+.B \-dead\-color \fIcolor\fP
+The color of the failed path (it is also stippled with a 50% pattern.)
+.TP 8
+.B \-skip\-color \fIcolor\fP
+The maze solver will choose to not go down a path if it can "see" (in a
+straight line) that it is a dead end.  This is the color to use for paths
+that are skipped for this reason.
+.TP 8
+.B \-surround\-color \fIcolor\fP
+If the maze solver ever completely encloses an area within the maze, then
+it knows that the exit is not in there (and in fact the interior of that
+area might not even be reachable.)  It will mark out those cells using this
+color.
+.TP 8
+.B \-solve\-delay \fIinteger\fP
+Delay (in microseconds) between each step of the solution path.
+Default 5000, or about 1/200th second.
+.TP 8
+.B \-pre\-delay \fIinteger\fP
+Delay (in microseconds) between generating a maze and starting to solve it.
+Default 2000000 (2 seconds.)
+.TP 8
+.B \-post\-delay \fIinteger\fP
+Delay (in microseconds) after solving a maze and before generating a new one.
+Default 4000000 (4 seconds.)
+.TP 8
+.B \-generator \fInum\fP
+Sets the algorithm that will be used to generate the mazes. The
+default is \-1, which randomly selects an algorithm for each maze that
+is generated. Generator 0 is the original one, and works by walking
+around randomly until we hit a place we've been before, then
+backtracking and trying a new direction somewhere. Generator 1 picks a
+random spot in the maze, then draws a straight wall from that spot in
+a random direction until it hits another wall (and continues until the
+maze is complete). Generator 2 is based on sets. Initially all cells
+are in different sets. Then two neighboring cells are chosen and if
+they are in different sets, their sets are joined. If they were in the
+same set, a wall is built between them. This continues until the maze is
+complete. 
+
+All generators generate mazes with a certain 'characteristic'. See if you
+can spot them!
+.TP 8
+.B \-max\-length \fInum\fP
+Controls the maximum length of walls drawn in one go by generator 1.
+.TP 8
+.B \-bridge
+.TP 8
+.B \-no\-bridge
+Controls whether or not a 'bridge' will appear over the logo.
+.PP
+Clicking the mouse in the maze window controls it.
+.TP 16
+.B "LeftButton
+Clears the window and restarts maze.
+.TP 16
+.B MiddleButton
+Pause or unpause the program.
+.TP 16
+.B RightButton
+Exit.
+.SH BUGS
+Expose events force a restart of maze.
+
+Mouse actions are based on "raw" values (Button1, Button2 and Button3)
+instead of using the pointer map.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fIseconds\fP
+How long to wait before starting over.  Default 5 seconds.
+.TP 8

+.SH NAME
+munch - munching squares screen hack
+.SH SYNOPSIS
+.B munch
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP]
+[\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install]
+[\-visual \fIvisual\fP] [\-delay \fIseconds\fP] [\-xor] [\-noxor] [\-shift]
+[\-noshift] [\-logminwidth \fIminimum width\fP]
+.SH DESCRIPTION
+The
+.I munch
+program preforms the munching squares hack until killed.  It picks square
+size, position, and gravity randomly; configurable options are listed
+below.
+.PP
+The munching squares hack cosists of drawing Y = X XOR T for a range of X
+and T over and over until all the possible combinations of X and T have
+come up.  It was reportedly discovered by Jackson Wright in 1962 and took 5
+instructions of PDP-6 code.
+.SH OPTIONS
+.I munch
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fIseconds\fP
+How long to wait before starting over.  Default 5 seconds.
+.TP 8
+.B \-xor
+Use the XOR drawing function.  (Default.)
+.TP 8
+.B \-no\-xor
+Don't use the XOR drawing function.
+.TP 8
+.B \-shift
+Start drawing the square at weird starting points.  (Default.)
+.TP 8
+.B \-no\-shift
+Don't shift and start drawing the square at weird starting points.
+.TP 8
+.B \-logminwidth \fIminimum\-width\fP
+The logarithm (base 2) of the minimum with of a square (must be a power of
+2, or some parts of the square aren't.)
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH HISTORY
+Quoted from HAKMEM, for historical interest.  As that document says, "Unless
+otherwise stated, all computer programs are in PDP-6/10 assembly language."
+.TP 8
+ITEM 146: MUNCHING SQUARES
+Another simple display program. It is thought that this was discovered by
+Jackson Wright on the RLE PDP-1 circa 1962.
+
+.EX
+    DATAI 2
+    ADDB 1,2
+    ROTC 2,-22
+    XOR 1,2

+.EE
+.RS 8
+2=X, 3=Y. Try things like 1001002 in data switches. This also does
+interesting things with operations other than XOR, and rotations other 
+than -22. (Try IOR; AND; TSC; FADR; FDV(!); ROT -14, -9, -20, ...)
+.RE
+.TP 8
+ITEM 147 (Schroeppel):
+Munching squares is just views of the graph Y = X XOR T for consecutive
+values of T = time.
+.TP 8
+ITEM 148 (Cohen, Beeler):
+A modification to munching squares which reveals them in frozen states
+through opening and closing curtains: insert FADR 2,1 before the XOR. Try
+data switches =
+
+.EX
+    4000,,4    1000,,2002    2000,,4    0,,1002
+.EE
+.RS 8
+(Notation: <left half>,,<right half>)
+
+Also try the FADR after the XOR, switches = 1001,,1.

+.SH NAME
+noseguy - a little guy with a big nose wanders around being witty
+.SH SYNOPSIS
+.B noseguy
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-text-foreground \fIcolor\fP] [\-text-background \fIcolor\fP] [\-font \fIfont\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP] [\-mode \fImode\fP] [\-program \fIprogram\fP] [\-filename \file\fP] [\-text \fItext\fP]
+.SH DESCRIPTION
+A little man with a big nose and a hat runs around spewing out messages to
+the screen.  This code (and its bitmaps) were extracted from the \fIxnlock\fP
+program.
+.SH OPTIONS
+.I noseguy
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-font \fIfont\fP
+The font used for the messages.
+.TP 8
+.B \-mode [ program | file | string ]
+In \fIprogram\fP mode, the messages are gotten by running a program.
+The program used is controlled by the \fI\-program\fP option, and 
+the \fI.program\fP resource.
+
+In \fIfilename\fP mode, the message used is the contents of a file.
+The file used is controlled by the \fI\-file\fP option, and 
+the \fI.filename\fP resource.
+
+In \fIstring\fP mode, the message is whatever was specified on the 
+command line as the \fI\-text\fP option, or in the resource database
+as the \fI.text\fP resource.
+.TP 8
+.B \-program \fIprogram\fP
+If \fImode\fP is \fIprogram\fP (the default), then this program will be
+run periodically, and its output will be the text of the messages.  The
+default program is \fI"fortune -s"\fP, but \fIyow\fP is also a good choice.
+.TP 8
+.B \-filename \fIfile\fP
+If \fImode\fP is \fIfile\fP, then the contents of this file will be used
+for all messages.
+.TP 8
+.B \-text \fIstring\fP
+If \fImode\fP is \fIstring\fP, then this text will be used for all messages.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH SEE ALSO
+.BR X (1),
+.BR xscreensaver (1),
+.BR xnlock (1)

+.SH NAME
+pedal - pretty geometric picture program
+.SH SYNOPSIS
+.B pedal
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-delay \fIseconds\fP] [-maxlines \fInumber\fP] [-fadedelay \fIuseconds\fP] [-mono] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIpedal\fP program displays pretty geometric pictures.
+.SH OPTIONS
+.I pedal
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-foreground \fIcolor\fP
+The color for the foreground.  Default is white.
+.TP 8
+.B \-background \fIcolor\fP
+The color for the background.  Default is black.
+.TP 8
+.B \-delay \fIseconds\fP
+The number of seconds to pause between each picture.
+.TP 8
+.B \-maxlines \fInumber\fP
+The maximum number of lines in the drawing.  Good values are
+between 20 and 2000.  Maximum value is 16K.
+.TP 8
+.B \-fadedelay \fImicroseconds\fP
+The number of micro seconds to take when fading in and out.
+.TP 8
+.B \-mono
+Don't do fading.  Pretend we're on a monochrome display.
+.PP
+To make your X server grunt under load, and to impress your
+friends, try \fIpedal -mono -delay 0 -maxlines 100\fp.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * penetrate simulates the arcade classic with the cities and the stuff
+ * shooting down from the sky and stuff. The computer plays against itself,
+ * desperately defending the forces of good against those thingies raining
+ * down. Bonus cities are awarded at ever-increasing intervals. Every five
+ * levels appears a bonus round. The computer player gets progressively
+ * more intelligent as the game progresses. Better aim, more economical with
+ * ammo, and better target selection. Points are in the bottom right, and
+ * high score is in the bottom left. Start with -smart to have the computer
+ * player skip the learning process.

+/*  As reported in News of the Weird:
+
+         In April, Sir Roger Penrose, a British math professor who has worked
+         with Stephen Hawking on such topics as relativity, black holes, and
+         whether time has a beginning, filed a copyright-infringement lawsuit
+         against the Kimberly-Clark Corporation, which Penrose said copied a
+         pattern he created (a pattern demonstrating that "a nonrepeating
+         pattern could exist in nature") for its Kleenex quilted toilet paper.
+         Penrose said he doesn't like litigation but, "When it comes to the
+         population of Great Britain being invited by a multinational to wipe
+         their bottoms on what appears to be the work of a Knight of the
+         Realm, then a last stand must be taken."

+ * This implementation uses the simpler version of the growth
+ * algorithm, i.e., if there are no forced vertices, a randomly chosen
+ * tile is added to a randomly chosen vertex (no preference for those
+ * 108 degree angles).
+ *
+ * There are two essential differences to the algorithm presented in
+ * the literature: First, we do not allow the tiling to enclose an
+ * untiled area.  Whenever this is in danger of happening, we just
+ * do not add the tile, hoping for a better random choice the next
+ * time.  Second, when choosing a vertex randomly, we will take
+ * one that lies withing the viewport if available.  If this seems to
+ * cause enclosures in the forced rule case, we will allow invisible
+ * vertices to be chosen.
+ *
+ * Tiling is restarted whenever one of the following happens: there
+ * are no incomplete vertices within the viewport or the tiling has
+ * extended a window's length beyond the edge of the window
+ * horizontally or vertically or forced rule choice has failed 100
+ * times due to areas about to become enclosed.

+.TH XScreenSaver 1 "10-May-97" "X Version 11"
+.SH NAME
+penrose - draws quasiperiodic tilings
+.SH SYNOPSIS
+.B penrose
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-redoDelay \fIseconds\fP] [\-size \fIinteger\fP] [\-ammann] [\-no\-ammann]
+
+.SH DESCRIPTION
+The \fIpenrose\fP program draws quasiperiodic tilings.
+
+See Onoda, Steinhardt, DiVincenzo and Socolar in
+Phys. Rev. Lett. 60, #25, 1988 or
+Strandburg in Computers in Physics, Sep/Oct 1991.
+
+This implementation uses the simpler version of the growth
+algorithm, i.e., if there are no forced vertices, a randomly chosen
+tile is added to a randomly chosen vertex (no preference for those
+108 degree angles).
+
+There are two essential differences to the algorithm presented in
+the literature: First, we do not allow the tiling to enclose an
+untiled area.  Whenever this is in danger of happening, we just
+do not add the tile, hoping for a better random choice the next
+time.  Second, when choosing a vertex randomly, we will take
+one that lies withing the viewport if available.  If this seems to
+cause enclosures in the forced rule case, we will allow invisible
+vertices to be chosen.
+
+Tiling is restarted whenever one of the following happens: there
+are no incomplete vertices within the viewport or the tiling has
+extended a window's length beyond the edge of the window
+horizontally or vertically or forced rule choice has failed 100
+times due to areas about to become enclosed.
+
+Although quasiperiodic tilings are produced, the tiles themselves are
+not penrose tiles (darts and kites). In contrast to penrose tiles,
+these tiles can be arranged to form a periodic tiling.
+
+.SH OPTIONS
+.I penrose
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors are chosen randomly.
+.TP 8
+.B \-size \fIinteger\fP
+How big the tiles should be.  Default 40 pixels.
+
+.TP 8
+.B \-delay \fImilliseconds\fP
+How long (in 1/1,000,000'ths of a second) to wait between drawing each
+tile.  Default 10,000 or .01 seconds.
+
+.TP 8
+.B \-redoDelay \fIseconds\fP
+How long to wait between starting a completely new tiling.  Default 3 seconds.
+
+.TP 8
+.B \-ammann \fIinteger\fP
+.TP 8
+.B \-no\-ammann \fIinteger\fP
+Whether Ammann lines should be added.
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * Brief description of options/resources:
+ *
+ * delay: the delay in microseconds between iterations
+ * size: the size of a cell in pixels
+ * count: the number of different kinds of mold (minimum: 2)
+ * diaglim: the age limit for diagonal growth as a multiplier of orthogonal
+ *   growth (minimum: 1, maximum 2). 1 means square growth, 1.414 
+ *   (i.e., sqrt(2)) means approximately circular growth, 2 means diamond
+ *   growth.
+ * anychan: the chance (fraction, between 0 and 1) that at each iteration,
+ *   any new cell will be born
+ * minorchan: the chance (fraction, between 0 and 1) that, given that new
+ *   cells will be added, that only two will be added (a minor cell birth
+ *   event)
+ * instantdeathchan: the chance (fraction, between 0 and 1) that, given
+ *   that death and destruction will happen, that instead of using plague
+ *   cells, death will be instantaneous
+ * minlifespan: the minimum lifespan of a colony (before black death ensues)
+ * maxlifespan: the maximum lifespan of a colony (before black death ensues)
+ * minlifespeed: the minimum speed for living cells as a fraction of the
+ *   maximum possible speed (fraction, between 0 and 1)
+ * maxlifespeed: the maximum speed for living cells as a fraction of the
+ *   maximum possible speed (fraction, between 0 and 1)
+ * mindeathspeed: the minimum speed for black death cells as a fraction of the
+ *   maximum possible speed (fraction, between 0 and 1)
+ * maxdeathspeed: the maximum speed for black death cells as a fraction of the
+ *   maximum possible speed (fraction, between 0 and 1)
+ * originalcolors: if true, count must be 8 or less and the colors are a 
+ *   fixed set of primary and secondary colors (the artist's original choices)
+ *
+ * Interesting settings:
+ *
+ *      petri -originalcolors -size 8
+ *      petri -size 2
+ *      petri -size 8 -diaglim 1.8
+ *      petri -diaglim 1.1

+
+   "lbearing" is the distance from the leftmost pixel of a character to
+   the logical origin of that character.  That is, it is the number of
+   pixels of the character which are to the left of its logical origin.
+
+   "rbearing" is the distance from the logical origin of a character to
+   the rightmost pixel of a character.  That is, it is the number of
+   pixels of the character to the right of its logical origin.
+
+   "descent" is the distance from the bottommost pixel of a character to
+   the logical baseline.  That is, it is the number of pixels of the
+   character which are below the baseline.
+
+   "ascent" is the distance from the logical baseline to the topmost pixel.
+   That is, it is the number of pixels of the character above the baseline.
+
+   Therefore, the bounding box of the "ink" of a character is
+   lbearing + rbearing by ascent + descent;
+
+   "width" is the distance from the logical origin of this character to
+   the position where the logical orgin of the next character should be
+   placed.
+
+   For our purposes, we're only interested in the part of the character
+   lying inside the "width" box.  If the characters have ink outside of
+   that box (the "charcell" box) then we're going to lose it.  Alas.

+.SH NAME
+pyro - simulate fireworks
+.SH SYNOPSIS
+.B pyro
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-count \fIinteger\fP] [\-frequency \fIinteger\fP] [\-scatter \fIinteger\fP]
+.SH DESCRIPTION
+The \fIpyro\fP program simulates fireworks, in a way similar to a Macintosh
+program of the same name.
+.SH OPTIONS
+.I pyro
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-count \fIinteger\fP
+How many particles should be allowed on the screen at once.  Default 100.
+.TP 8
+.B \-frequency \fIinteger\fP
+How often new missiles should launch.  Default 30.
+.TP 8
+.B \-scatter \fIinteger\fP
+How many particles should appear when a missile explodes.  Default 20.
+The actual number used is between \fIN\fP and \fIN+(N/2)\fP.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+qix - bounce colored lines around a window
+.SH SYNOPSIS
+.B qix
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-segments \fIint\fP] [\-spread \fIpixels\fP] [\-size \fIpixels\fP] [\-count \fIint\fP] [\-color-shift \fIdegrees\fP] [\-delay \fIusecs\fP] [\-random] [\-linear] [\-solid] [\-hollow] [\-xor] [\-no\-xor] [\-transparent] [\-non\-transparent] [\-additive] [\-subtractive] [\-poly \fIint\fP] [\-gravity] [\-no\-gravity]
+.SH DESCRIPTION
+The \fIqix\fP program bounces a series of line segments around its window.
+This is truly the swiss army chainsaw of qix programs.  If you know of one
+with more display modes, I want to know about it.
+.SH OPTIONS
+.I qix
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-segments \fIinteger\fP
+How many line segments should be drawn.  Default 50.
+.TP 8
+.B \-spread \fIinteger\fP
+How far apart the endpoints of one segment should be from the next.
+Default 8.
+.TP 8
+.B \-size \fIinteger\fP
+The maximum distance one endpoint of a segment is allowed to be from
+the opposite end of that segment.  Default 0, meaning unlimited.
+.TP 8
+.B \-count \fIinteger\fP
+How many qixes to draw.  Default 1.
+.TP 8
+.B \-color\-shift \fIdegrees\fP
+If on a color display, the color of the line segments will cycle through
+the spectrum.  This specifies how far the hue of each segment should be
+from the next, in degrees on the HSV wheel.  Default 3.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 25000, or about 0.025 seconds.
+.TP 8
+.B \-random
+The \fIqix\fP will wander around the screen semi-randomly.  This is the
+default.
+.TP 8
+.B \-linear
+The opposite of \fI\-random\fP: the \fIqix\fP will travel in straight lines
+until it reaches a wall, and then it will bounce.
+.TP 8
+.B \-solid
+If this is specified, then the area between the line segments will be filled
+in with the appropriate color, instead of the \fIqix\fP simply being composed
+of one-pixel-wide line segments.  This option looks really good in color.
+.TP 8
+.B \-hollow
+The opposite of \fI\-solid\fP; this is the default.
+.TP 8
+.B \-xor
+If this is specified, then qix segments will be drawn and erased with xor,
+instead of being drawn in some color and erased in the background color.
+This implies \fI\-mono\fP, in that only two colors can be used.
+.TP 8
+.B \-transparent
+If this is specified, and \fI\-count\fP is greater than 1, then each qix
+will be drawn in one color, and when they overlap, the colors will be mixed.
+This looks best in conjuction with \fI\-solid\fP.
+.TP 8
+.B \-non\-transparent
+Turns off \fI\-transparent\fP.
+.TP 8
+.B \-additive
+If \fI\-transparent\fP is specified, then this option means that the colors
+will be mixed using an additive color model, as if the qixes were projected
+light.  This is the default.
+.TP 8
+.B \-subtractive
+If \fI\-transparent\fP is specified, then this option means that the
+colors will be mixed using a subtractive color model, as if the qixes were
+translucent filters.
+.TP 8
+.B \-poly \fIint\fP
+How many vertices each qix-line should have: the default is 2, meaning the
+traditional qix line shape.  Three will yield triangles, and so on.
+.TP 8
+.B \-gravity
+.TP 8
+.B \-no\-gravity
+Whether there should be downward attraction.  For example, the
+options
+.B \-gravity \-linear
+will make everything move in nice smooth parabolas.
+Gravity is off by default.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+     visuals that I do have, and I think that's because I mistakenly
+     wrote `pfv[i].depth' when I meant to write `pfv[i].bits_per_pixel'.
+     The symptom I was seeing was that the grid was 64x64, but the

+.TH XScreenSaver 1 "10-May-97" "X Version 11"
+.SH NAME
+rd-bomb - reaction/diffusion textures
+.SH SYNOPSIS
+.B rd-bomb
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP]
+[\-background \fIcolor\fP] [\-window] [\-root] [\-install]
+[\-visual \fIvisual\fP] [\-width \fIn\fP] [\-height \fIn\fP]
+[\-reaction \fIn\fP] [\-diffusion \fIn\fP]
+[\-size \fIf\fP] [\-speed \fIf\fP] [\-delay \fIusecs\fP]
+.SH DESCRIPTION
+
+The \fIrd-bomb\fP program draws reaction/diffusion textures.  The code
+is derived from the 'd' mode of the "bomb" visual musical instrument
+(see http://www.cs.cmu.edu/~spot/bomb.html).  I got the equations from
+xmorphia (http://www.ccsf.caltech.edu/ismap/image.html), which is
+based on a version of the Gray-Scott model taken from:
+    John E. Pearson "Complex Patterns in a Simple System"
+    Science, 261,189, 9 July 1993.
+
+If the frame-rate is too low, consider decreasing the width and height
+of the tile, or decreasing the size of the active part of the screen.
+
+.SH OPTIONS
+
+If one of the reaction, diffusion, radius, and palette options is set
+to a negative value, then that option will be set to a random
+appropriate value.
+
+Be sure to try "-speed 1 -size 0.1 -epoch 3000".
+
+.I rd-bomb
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-width \fIn\fP
+.TP 8
+.B \-height \fIn\fP
+Specify the size of the tile, in pixels.
+.TP 8
+.B \-reaction \fIn\fP
+.TP 8
+.B \-diffusion \fIn\fP
+These are constants in the equations that effect its visual nature.
+Each may be one of 0, 1, or 2.  
+.TP 8
+.B \-radius \fIn\fP
+Size of the seed.
+.TP 8
+.B \-palette \fIn\fP
+Selects a palette.  Must be between 0 and 80, inclusive.
+.TP 8
+.B \-size \fIf\fP
+What fraction of the window is actively drawn, a floating point number
+between 0 (exclusive) and 1 (inclusive).  Default is 0.66.
+.TP 8
+.B \-speed \fIf\fP
+When a fraction of the screen is active, the active area moves at this
+rate (a floating point number).  Default is zero.  Suggested value: 1.0.
+.TP 8
+.B \-delay \fIusecs\fP
+How many microseconds to delay between frames; default 1000, or 
+about 1/1000th of a second.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "13-aug-92" "X Version 11"
+.SH NAME
+rocks - animation of flying through an asteroid field
+.SH SYNOPSIS
+.B rocks
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-ncolors \fIn\fP] [\-install] [\-visual \fIvisual\fP] [\-count \fIinteger\fP] [\-delay \fIusecs\fP] [\-speed \fIinteger\fP] [\-norotate] [\-nomove] [\-3d]
+.SH DESCRIPTION
+The \fIrocks\fP program draws an animation of an asteroid field moving past
+the observer (or vice versa).  Sometimes the observer picks up spin on Z axis.
+.SH OPTIONS
+.I rocks
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono
+Make all the rocks the same color.
+.TP 8
+.B \-ncolors colors
+How many different colors to use.  Default 5.  Colors are chosen randomly.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-count \fIinteger\fP
+Maximum number of rocks to draw on the screen at once.  Default 100.
+.TP 8
+.B \-speed \fIinteger\fP
+A measure of the speed with which the observer and the rocks pass each other,
+from 1 to 100.  Default 100, meaning ``very fast.''  If you're on a slow 
+display connection (the animation looks jerky) then try making this number 
+smaller, and/or decreasing the number of rocks.
+.TP 8
+.B \-delay \fImicroseconds\fP
+Number of microseconds to delay between each frame.  Default 50000, meaning
+about 1/20th second.  Compare and contrast with \fI\-speed\fP, above.
+.TP 8
+.B \-norotate
+Don't rotate the observer; just fly through the field on the level.
+.TP 8
+.B \-nomove
+Don't turn the observer; just fly straight ahead through the field.
+.TP 8
+.B \-3d
+Do red/blue 3d separations: if you look at the screen with 3d glasses,
+the rocks will be \fIjumping\fP right \fIout\fP at you.  Oooooh, scaaary!
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH SEE ALSO
+.BR X (1),
+.BR xscreensaver (1)
+.SH BUGS
+There should be an option to display doppler shift (a gravity rainbow.)
+
+Speed of rotation should be settable.
+
+Default speed of rotation should be relative to forward velocity.

+.TH XScreenSaver 1 "13-aug-92" "X Version 11"
+.SH NAME
+rorschach - simulate ink-blot patterns
+.SH SYNOPSIS
+.B rorschach
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-iterations \fIinteger\fP] [\-offset \fIinteger\fP] [\-xsymmetry] [\-ysymmetry] [\-erase\-mode \fIinteger\fP] [\-erase\-speed \fIusecs\fP] [\-delay \fIsecs\fP]
+.SH DESCRIPTION
+The \fIrorschach\fP program draws random patterns reminiscent of the
+psychological test of same name.
+.SH OPTIONS
+.I rorschach
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-iterations \fIinteger\fP
+How many dots should be drawn each time.  Default 4000.
+.TP 8
+.B \-offset \fIinteger\fP
+How far apart the dots should be.  Default 4 pixels.
+.TP 8
+.B \-xsymmetry
+Whether the images should be horizontally symmetrical.  Default true.
+.TP 8
+.B \-ysymmetry
+Whether the images should be vertically symmetrical.  Default false.
+.TP 8
+.B \-erase\-mode \fIinteger\fP
+This sets the erase mode. Mode \-1 chooses a random mode each time. There
+are currently 6 modes defined (0\-5).
+.TP 8
+.B \-erase\-speed \fIusecs\fP
+This controls the speed at which the screen will be erased. (Delay between
+erasing of individual lines.)
+.TP 8
+.B \-delay \fIseconds\fP
+This sets the number of seconds that the figure will be on the screen.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH BUGS
+May call your sanity into question.

+ *
+ * Description:
+ *  There are two little shading circles (bobs) that zip around the screen.
+ *  one of them shades up towards white, and the other shades down toward
+ *  black.
+ *  This keeps the screen in color balance at a chosen color.
+ *
+ *  Its kinda like 'The Force'
+ *   There is a light side, a dark side, and it keeps the world in balance.
+ *
+ * [05/23/99] - Shane Smit: Creation
+ * [05/26/99] - Shane Smit: Port to C/screenhack for use with XScreenSaver
+ * [06/11/99] - Shane Smit: Stopped trying to rape the palette.
+ * [06/20/99] - jwz: cleaned up ximage handling, gave resoources short names,
+ *                introduced delay, made it restart after N iterations.
+ * [06/21/99] - Shane Smit: Modified default values slightly, color changes
+ *                on cycle, and the extents of the sinus pattern change in
+ *                real-time.
+ * [06/22/99] - Shane Smit: Fixed delay to be fast and use little CPU :).

+.SH DESCRIPTION
+The \fIsierpinski\fP program draws Sierpinski triangle fractals.
+.SH OPTIONS
+.I sierpinski
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors are chosen randomly.
+.TP 8
+.B \-cycles \fIinteger\fP
+
+.TP 8
+.B \-count \fIinteger\fP
+
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.

+.TH XScreenSaver 1 "24-Nov-97" "X Version 11"
+.SH NAME
+slidescreen - permute the screen image like an 8-puzzle
+.SH SYNOPSIS
+.B slidescreen
+[\-display \fIhost:display.screen\fP] [\-background \fIcolor\fP] [\-grid-size \fIpixels\fP] [\-ibw \fIpixels\fP] [\-increment \fIpixels\fP] [\-delay \fIusecs\fP] [\-delay2 \fIusecs\fP] [\-window] [\-root] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIslidescreen\fP program takes an image of the screen, divides it into
+a grid, deletes a random square of that grid, and then randomly slides 
+one of the neighbors of this "hole" into the hole (and repeat.)
+.SH OPTIONS
+.I slidescreen
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-grid-size \fIpixels\fP
+The size of the grid cells.  Default 70 pixels.
+.TP 8
+.B \-ibw \fIpixels\fP
+The size of the "gutter" between grid cells.  Default 1 pixel.
+.TP 8
+.B \-increment \fIpixels\fP
+How many pixels by which a piece should be moved when sliding to a new 
+location.  Default 10 pixels.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation of
+the motion of each segment.  Default 50000, which is 0.05 seconds.  This
+is closely related to the \fI\-increment\fP parameter.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between the end of the motion of
+one segment and the beginning of the motion of another.  Default 1000000,
+which is one second.
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead.  The following resources control that.
+.PP
+.TP 8
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image, 
+between 0.0 and 1.0.  Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first.  If unspecified, 
+the default camera (from videopanel(1)) will be checked first.  After that, all
+other available video input devices will be checked in order.  
+
+The first one which produces a non-black image will be used.  If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image.  This defaults to 2.2.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "24-Nov-97" "X Version 11"
+.SH NAME
+slip - sucks your screen into a jet engine
+.SH SYNOPSIS
+.B slip
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-iterations \fIinteger\fP] [\-points \fIinteger\fP] [\-delay \fImicroseconds\fP] [\-delay2 \fImicroseconds\fP]
+.SH DESCRIPTION
+The \fIslip\fP program does lots of blits and chews up your screen image.
+.SH OPTIONS
+.I slip
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 128.
+The colors used cycle through the hue, making N stops around 
+the color wheel.
+.TP 8
+.B \-count \fIinteger\fP
+How many whooziwhatsis to generate.  Default 35.
+.TP 8
+.B \-cycles \fIinteger\fP
+How long to frobnicate.  Default 50.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long we should wait between drawing each step.  Default 50000,
+or about 1/20th second.
+
+.SH RESOURCES
+On some systems (currently, only SGIs), this program can, instead of grabbing
+a desktop image, grab a frame of video from an external camera and manipulate
+that instead.  The following resources control that.
+.PP
+.TP 8
+.B grabVideoProbability \fR(Float)\fP
+What portion of the time to grab video rather than a screen image, 
+between 0.0 and 1.0.  Defaults to 0.5, or half the time.
+.TP 8
+.B videoDevice \fR(Integer)\fP
+The number of the default video input device to check first.  If unspecified, 
+the default camera (from videopanel(1)) will be checked first.  After that, all
+other available video input devices will be checked in order.  
+
+The first one which produces a non-black image will be used.  If all images
+are black, the others will be re-checked a few times before giving up and
+falling back to simply grabbing a desktop image (but note that this takes a
+few seconds, so if you don't actually have any video sources hooked up, you
+should consider turning off video grabbing by setting
+\fBgrabVideoProbability\fP to 0.0.)
+.TP 8
+.B videoGain \fR(Float)\fP
+The amount by which to brighten the grabbed image.  This defaults to 2.2.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+/* sonar.c --- Simulate a sonar screen.
+ *
+ * This is an implementation of a general purpose reporting tool in the
+ * format of a Sonar display. It is designed such that a sensor is read
+ * on every movement of a sweep arm and the results of that sensor are
+ * displayed on the screen. The location of the display points (targets) on the
+ * screen are determined by the current localtion of the sweep and a distance
+ * value associated with the target. 
+ *
+ * Currently the only two sensors that are implemented are the simulator
+ * (the default) and the ping sensor. The simulator randomly creates a set
+ * of bogies that move around on the scope while the ping sensor can be
+ * used to display hosts on your network.
+ *
+ * The ping code is only compiled in if you define HAVE_ICMP or HAVE_ICMPHDR,
+ * because, unfortunately, different systems have different ways of creating
+ * these sorts of packets.
+ *
+ * Also: creating an ICMP socket is a privileged operation, so the program
+ * needs to be installed SUID root if you want to use the ping mode.  If you
+ * check the code you will see that this privilige is given up immediately
+ * after the socket is created.
+ *
+ * It should be easy to extend this code to support other sorts of sensors.
+ * Some ideas:
+ *   - search the output of "netstat" for the list of hosts to ping;
+ *   - plot the contents of /proc/interrupts;
+ *   - plot the process table, by process size, cpu usage, or total time;
+ *   - plot the logged on users by idle time or cpu usage.

+ * $Revision: 1.12 $
+ *
+ * Version 1.0 April 27, 1998.
+ * - Initial version
+ * - Submitted to RedHat Screensaver Contest
+ * 
+ * Version 1.1 November 3, 1998.
+ * - Added simulation mode.
+ * - Added enhancements by Thomas Bahls <thommy@cs.tu-berlin.de>
+ * - Fixed huge memory leak.
+ * - Submitted to xscreensavers
+ * 
+ * Version 1.2
+ * - All ping code is now ifdef-ed by the compile time symbol HAVE_PING;
+ *   use -DHAVE_PING to include it when you compile.
+ * - Sweep now uses gradients.
+ * - Fixed portability problems with icmphdr on some systems.
+ * - removed lowColor option/resource.
+ * - changed copyright notice so that it could be included in the xscreensavers
+ *   collection.
+ *
+ * Version 1.3 November 16, 1998.
+ * - All ping code is now ifdef-ed by the compile time symbol PING use -DPING
+ *   to include it when you compile.
+ * - Sweep now uses gradients.
+ * - Fixed portability problems with icmphdr on some systems.
+ * - removed lowcolour option/resource.
+ * - changed copyright notice so that it could be included in the xscreensavers
+ *   collection.
+ *
+ * Version 1.4 November 18, 1998.
+ * - More ping portability fixes.
+ *
+ * Version 1.5 November 19, 1998.
+ * - Synced up with jwz's changes.
+ * - Now need to define HAVE_PING to compile in the ping stuff.

+.SH DESCRIPTION
+The \fIsonar\fP program displays a sonar scope on the computer's screen.
+This scope polls a sensor as the sweep goes around the scope and displays
+what it finds as bogies on the screen.  The program is designed to support
+different modes representing different types of sensors.  Currently the
+only implemented sensors are a simulator, and a network ping function that
+pings hosts and plots the results on the scope.
+.SH OPTIONS
+.I sonar
+understands the following options:
+.TP 8
+.B \-background \fIColor\fP
+The background Color of the screen not covered by the scope.
+.TP 8
+.B \-sweep\-color \fIColor\fP
+The color of the brightest part of the sweep.
+.TP 8
+.B \-scope\-color \fIColor\fP
+The color of the circular part of the scope.
+.TP 8
+.B \-grid\-color \fIColor\fP
+The color to the grid lines overlaying the scope.
+.TP 8
+.B \-text\-color \fIColor\fP
+The color of the text identifying bogies on the scope.
+.TP 8
+.B \-ttl \fIinteger\fP
+"Time to live": visible time of a Bogie. Try values between 10 (very short)
+and 100. 
+.TP 8
+.B \-mode \fIsimulation | ping\fP
+The sensor mode to use, the currently supported modes \fIsimulate\fP (the
+default) and \fIping\fP.
+.TP 8
+.B \-font \fIfont\fP
+The font used to display text on the scope.  Default "fixed".
+.TP 8
+.B \-ping\-timeout \fIint\fP
+The amount of time in milliseconds the program will wait for an answer
+to a ping.
+.TP 8
+.B \-ping\-source list | file | subnet
+Th source of the list of hosts to ping. Valid values are: \fIlist\fP,
+\fIfile\fP, \fIsubnet\fP.  The first two values are described below;
+and \fIsubnet\fP indicates that the sonar should ping all hosts in the
+same subnet as the current machine.  (All addresses are treated
+as class C nets, therefore this will at most ping 254 hosts.)
+.TP 8
+.B \-ping\-file \fIfilename\fP
+The path to a file listing the hosts to ping.  This file can be in the
+format used by \fI/etc/hosts\fP, or it can be any file that has host
+names as the first element on each line.  If you use ssh, try this:
+.EX
+sonar -mode ping -ping-file $HOME/.ssh/known_hosts
+.EE
+This is used only used when \fIpingSource\fP is set to \fBfile\fP.
+.TP 8
+.B \-ping\-list \fIlist\fP
+A comma separated list of hostnames, eg \fI"pinky,brain,dot"\fP.
+Only used when \fIpingSource\fP is set to \fBlist\fP.
+.TP 8
+.B \-team-a-name \fIstring\fP
+The name of team A, in simulation-mode.
+.TP 8
+.B \-team-b-name \fIstring\fP
+The name of team B, in simulation-mode.
+.TP 8
+.B \-team-a-count \fIint\fP
+The number of bogies on team A, in simulation-mode.
+.TP 8
+.B \-team-b-count \fIint\fP
+The number of bogies on team B, in simulation-mode.
+.SH RESOURCES
+Configuration of the targets to ping is best done by setting X Resources.

+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors are chosen randomly.
+.SH ENVIRONMENT

+.TH XScreenSaver 1 "18-mar-1999" "X Version 11"
+.SH NAME
+squiral - square spirals screensaver
+.SH SYNOPSIS
+.B squiral
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP]
+[\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install]
+[\-noinstall] [\-visual \fIvisual\fP] [\-fill \fIpercent\fP] [-count
+\fInumber\fP] [-delay \fIusec\fP] [-disorder \fIfraction\fP] [-handedness
+\fIfraction\fP] [-cycle]
+.SH DESCRIPTION
+The \fIsquiral\fP program displays interacting, spiral-producing automata
+
+.SH OPTIONS
+.I squiral
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-fill \fIpercent\fP
+Specify the percent (0-100) of the screen which must be filled before
+the screen is cleared.  60-80 percent are good values.
+.TP 8
+.B \-count \fInumber\fP
+The number of squiralies.  By default, the screen width divided by 32.
+.TP 8
+.B \-delay \fIusec\fP
+The wait between steps.  The default is 1000.
+.TP 8
+.B \-disorder \fIfraction\fP
+The fraction of the time a squiraly will choose a new direction.
+The default is 0.005.
+.TP 8
+.B \-handedness \fIfraction\fP
+The fraction of the time a squiraly will choose to enter lefthanded
+mode.  0.0 means exclusively right-handed behavior, 0.5 (the default) is
+a balance between the two, and 1.0 is exclusively left-handed behaviour.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH XScreenSaver 1 "14-Jun-97" "X Version 11"
+.SH NAME
+starfish - radially-symmetric throbbing colormap-hacking graphics demo
+.SH SYNOPSIS
+.B starfish
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-delay \fIusecs\fP] [\-delay2 \fIsecs\fP] [\-cycle\-delay2 \fIusecs\fP] [\-thickness \fIpixels\fP] [\-rotation \fIdegrees\fP] [\-duration \fIseconds\fP] [\-colors \fIint\fP] [\-cycle] [\-no\-cycle] [\-blob] [\-no\-blob]
+.SH DESCRIPTION
+The \fIstarfish\fP program draws radially symmetric objects, which expand,
+contract, rotate, and turn inside out.  It uses these shapes to lay down a
+field of smooth colors, and then rotates the colormap.
+.SH OPTIONS
+.I starfish
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the animation.
+Default 10000, or about 1/100th second.
+.TP 8
+.B \-cycle\-delay \fImicroseconds\fP
+How long to wait between shifing the colormap by one step.
+Default 100000, or about 1/10th second.
+.TP 8
+.B \-thickness \fIpixels\fP
+How wide each color band should be.  Default 0, meaning random (the chosen
+value will be between 0 and 15.)
+.TP 8
+.B \-rotation \fIdegrees\fP
+How quickly the objects should rotate at each step.  Default 0, meaning 
+random (the chosen value will be between 0 and 12 degrees.)
+.TP 8
+.B \-colors \fIint\fP
+How many colors to use.  Default 200.  The more colors, the smoother the
+transitions will be, and the nicer the resultant images.
+.TP 8
+.B \-cycle
+.TP 8
+.B \-no\-cycle
+Whether to do colormap cycling.  Default true.
+.TP 8
+.B \-duration \fIseconds\fP
+How long to run before choosing a new shape.  Default 30 seconds.
+.TP 8
+.B \-delay2 \fIseconds\fP
+When \fIduration\fP expires, how long to wait before starting a new run.
+Default 5 seconds.
+.TP 8
+.B \-blob
+.TP 8
+.B \-no\-blob
+If \fIblob\fP option is specified, then the raw shapes will be shown, 
+instead of a field of colors generated from them.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+strange - draws strange attractors
+.SH SYNOPSIS
+.B strange
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP]
+
+.SH DESCRIPTION
+The \fIstrange\fP program draws strange attractors
+.SH OPTIONS
+.I strange
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 64.
+The colors are chosen randomly.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.TH t3d 1 "Version 1.1" "Time 3D"
+.SH NAME
+t3d \- clock using flying balls to display the time
+.SH SYNOPSIS
+t3d [ \f2 options\f1 ]...
+.SH DESCRIPTION
+.PP
+Time 3D is a clock. It uses flying balls to display the time. This
+balls move and wobble around to give you the impression your
+graphic workstation with its many XStones is doing something.
+.PP
+t3d uses mouse and keyboard to let you fly through the balls. Hit
+.B S
+to speed up, 
+.B A
+to slow down,
+.B Z
+to zoom in and
+.B X
+to zoom out.
+Use the
+.B left mouse button
+to rotate to the left and the
+.B right mouse button
+to rotate the view to the right. Use the
+.B middle mouse button
+to change the optical axis and the moving direction.
+.B 0
+(zero) will stop you.
+.B Q
+quits.
+.PP
+.SH OPTIONS
+.TP
+.BI "-move " "factor"
+Modifies the direction move of t3d. The clock looks 30 degrees*
+.I factor
+to the left and to the right periodically.
+.TP
+.BI "-wobble " "factor"
+Modifies the wobbling (sounds nice :-) of t3d by multiplying the
+default deformation of the clock with
+.I factor.
+.TP
+.B -minutes
+Shows one small ball for every minute, instead of one for every 2.5 minutes.
+.TP
+.BI "-mag " "factor"
+Changes the magnification of t3d. By default, t3d draws a 200x200 image.
+A .I factor
+of 2 means, it will use a 400x400 image.
+.TP
+.BI "-cycle " "period"
+Sets the moving cycle to
+.I period
+seconds. By default, this value is 10 seconds.
+.TP
+.BI "-wait " "microsec"
+Inserts a wait after drawing one view of the clock. By default, t3d waits
+40 ms after each drawing. This helps you to keep the performance loss
+small.
+.TP
+.BI "-fast " "precalc_radius"
+t3d uses bitmap copy to draw precalculated balls. You can specify the radius
+in pixels up to which t3d should precalculate balls. t3d will set a useful
+range by itself using the magnification when it is started.
+.TP
+.B -colcycle
+Draws cyclic the color scale used for the balls in the background instead
+of the normal black.
+.TP
+.BI "-rgb " "red green blue"
+Selects the color in RGB color space of the lightning spot on the balls.
+All the other colors used for balls or
+.B -colcycle
+are less intensive colors of the same hue and saturation. All values
+in range of 0 to 1.
+.TP
+.BI "-hsv " "hue saturation value"
+Selects the color in HSV color space.
+.I hue
+is in degrees from 0 to 360, all other values in range from 0 to 1. It gives
+nice but rather unpredictable results, if you use a saturation of e.g. 2.
+Try it at your own risk.
+.TP
+.BI "-hsvcycle " "speed"
+Rotates the hue axis every 10 seconds*
+.I speed.
+.TP
+.B -help
+Prints a short usage message.
+

+.SH AUTHOR
+.PP
+Bernd Paysan
+
+Email: bernd.paysan@gmx.de
+
+Hacked on by jwz@jwz.org for xscreensaver.
+
+.SH ACKNOWLEDGEMENT
+.PP
+Acknowledgement to Georg Acher, who wrote the initial program displaying
+balls.
+
+.SH COPYING
+.PP
+Copy, modify, and distribute T3D either under GPL version 2 or newer, or
+under the standard MIT/X license notice.
+
+.SH DISCLAIMER
+.PP
+T3D is not related to T3D(tm), the massive parallel Alpha--based
+supercomputer from Cray Research. T3D's name was invented in 1991,
+years before the project at Cray Research started. There is no
+relation from T3D to Cray's T3D, even the balls surrounding T3D on
+some posters weren't an inspiration for T3D. I don't know anything
+about the other way round.
+
+The programming style of T3D isn't intented as example of good style,
+but as example of how a fast prototyped demo may look like. T3D wasn't
+created to be useful, it was created to be nice.
+
+.SH KNOWN BUGS
+.PP
+There are no known bugs in T3D. Maybe there are bugs in X. Slight
+changes in the T3D sources are known to show these bugs, e.g. if
+you remove the (int) casting at the XFillArc x,y,w,h-coordinates...

+ *            to make common subroutines.  Simplified.
+ *               Ron Hitchens <ron@idiom.com>
+ * 07-Mar-96: Removed internal delay code, set MI_PAUSE(mi) for inter-scene
+ *            delays.  No other delays are needed here.
+ *            Made pause time sensitive to value of cycles (in 10ths of a
+ *            second).  Removed (hopefully) all references to globals.
+ *               Ron Hitchens <ron@idiom.com>
+ * 27-Feb-96: Undid the changes listed below.  Added ModeInfo argument.
+ *               Implemented delay between scenes using the MI_PAUSE(mi)
+ *            scheme.  Ron Hitchens <ron@idiom.com>
+ * 27-Dec-95: Ron Hitchens <ron@idiom.com>
+ *            Modified logic of draw_triangle() to provide a delay
+ *            (sensitive to the value of cycles) between each iteration.
+ *            Because this mode is so compute intensive, when the new
+ *            event loop adjusted the delay to compensate, this mode had
+ *            almost no delay time left.  This change pauses between each
+ *            new landscape, but could still be done better (it is not
+ *            sensitive to input events while drawing, for example).
+ * 03-Nov-95: Many changes (hopefully some good ones) by David Bagley
+ * 01-Oct-95: Written by Tobias Gloth

+.TH XScreenSaver 1 "17-Jun-99" "X Version 11"
+.SH NAME
+vidwhacker - grab images and apply random filters to them
+.SH SYNOPSIS
+.B vidwhacker
+[\-display \fIhost:display.screen\fP] [\-root] [\-window] [\-verbose] [\-stdin] [\-stdout] [\-delay seconds]
+.SH DESCRIPTION
+The \fIvidwhacker\fP program grabs a image from the system's video input,
+applies random image filters to it, and displays the result.  
+The \fIvidwhacker\fP program does not terminate until killed.
+It depends heavily on
+.BR xv (1)
+and the various PBM tools
+(e.g.,
+.BR ppmrelief (1).)
+.SH OPTIONS
+.I vidwhacker
+accepts the following options:
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-window
+Pop up a new window displaying the image.  When a new image has been fully
+processed, destroy that window and pop up a new one.  This is the default.
+.TP 8
+.B \-verbose
+Print diagnostics.
+.TP 8
+.B \-stdin
+Instead of grabbing an image from the system's video input, read an image
+to maniupulate from stdin.  This image must be in 
+.TP 8
+.B \-delay \fIseconds\fP
+How long to sleep between images.  Default 3 seconds (the actual
+elapsed time is significantly longer, due to processing time.)
+.BR ppm (5)
+format.  The program will still perform repeated random image 
+transformations, but it will always use this one image as its starting point.
+.TP 8
+.B \-stdout
+Instead of displaying the image on a window or on the root, write the new
+image on stdout, and exit.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH BUGS
+Grabbing video images is, of course, very system-dependent.  It works
+on SGIs, and on Linux systems that have the
+.BR qcam (1)
+program.  If your system does things differently, you'll need to edit
+the vidwhacker script (look for the \fIgrab()\fP function.)
+
+It's slow.
+.SH TO DO
+It might be interesting to rewrite this to use
+.BR gimp (1)
+plugins instead of the pbm tools.  It probably wouldn't be any faster,
+but there would be a wider variety of effects available.
+.SH SEE ALSO
+.BR X (1),
+.BR xscreensaver (1),
+.BR xv (1),
+.BR ppmtogif (1),
+.BR cjpeg (1)

+.TH XScreenSaver 1 "10-May-97" "X Version 11"
+.SH NAME
+vines - draws pseudo-fractal geometric patterns
+.SH SYNOPSIS
+.B vines
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\fP]
+
+.SH DESCRIPTION
+The \fIvines\fP program is yet another geometric pattern generator, this
+one's claim to fame being a pseudo-fractal looking vine like pattern that
+creates nifty whorls and loops.
+.SH OPTIONS
+.I vines
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-ncolors \fIinteger\fP
+How many colors should be used (if possible).  Default 200.
+The colors are chosen randomly.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+.SH NAME
+webcollage - decorate the screen with random images from the web
+.SH SYNOPSIS
+.B webcollage
+[\-display \fIhost:display.screen\fP] [\-root] [\-verbose]
+[\-delay \fIsecs\fP] [\-timeout \fIsecs\fP] [\-background \fIbg\fP]
+[\-filter \fIcommand\fP] [\-filter2 \fIcommand\fP]
+.SH DESCRIPTION
+The \fIwebcollage\fP program pulls random image off of the World Wide Web
+and scatters them on the root window.  One satisfied customer described it
+as "a nonstop pop culture brainbath."  This program finds its images by
+doing random web searches, and extracting images from the returned pages.
+It places the images on the root window by using the
+.BR xv (1),
+.BR giftopnm (1),
+and
+.BR djpeg (1)
+tools.
+
+\fIwebcollage\fP also works as a CGI program, that will add images to the
+collage on a web page each time the page is loaded.  See the comments at 
+the top of the source code for installation instructions.
+
+\fIwebcollage\fP is written in
+.BR perl (1)
+and requires Perl 5.
+.SH OPTIONS
+.I webcollage
+accepts the following options:
+.TP 8
+.B \-root
+Draw on the root window.  This option is manditory: drawing to a window
+other than the root window is not yet supported.
+.TP 8
+.B \-verbose \fRor\fP \-v
+Print diagnostics to stderr.  Multiple \fI-v\fP switches increase the
+amount of output.  \fI-v\fP will print out only the URLs of the 
+images; \fI-vv\fP will print all the commands being run; and \fI-vvv\fP
+will print more than you care about.
+.TP 8
+.B \-delay \fIseconds\fP
+How long to sleep between images.  Default 1 second.  (Remember that
+this program probably spends a lot of time waiting for the network.)
+.TP 8
+.B \-background \fIcolor-or-ppm\fP
+What to use for the background onto which images are pasted.  This may be
+a color name, a hexadecimal RGB specification in the form '#rrggbb', or 
+the name of a PPM file.
+.TP 8
+.B \-timeout \fIseconds\fP
+How long to wait for a URL to complete before giving up on it and
+moving on to the next one.
+Default 30 seconds.
+.TP 8
+.B \-filter \fIcommand\fP
+Filter all source images through this command.  The command must take
+a PPM file on stdin, and write a new PPM file to stdout.  One good 
+choice for a filter would be:
+.EX
+webcollage -root -filter 'vidwhacker -stdin -stdout'
+.EE
+.TP 8
+.B \-filter2 \fIcommand\fP
+Filter the \fIcomposite\fP image through this command.  The \fI-filter\fP
+option applies to the sub-images; the \fI-filter2\fP applies to the
+final, full-screen image.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH FILES AND URLS
+.TP
+.I /usr/dict/words \fRor\fP /usr/share/lib/dict/words
+To find the random words to feed to search engines.
+.PP
+.I http://random.yahoo.com/bin/ryl, http://image.altavista.com/
+To find random web pages.
+.SH BUGS
+When drawing on the root window, it always uses the default colormap.
+This is actually a limitation of xv.  But regardless, when using this
+program with xscreensaver, it must be given the \fBdefault-n\fP 
+visual specification (see the
+.BR xscreensaver (1)
+manual for more details.)
+
+Only the GIF and JPEG image formats are supported.
+
+Transparent and animating GIFs are not supported.
+
+It's slow.
+
+Too many of the images that it finds are text, not pictures.  This is 
+because most of the web is pictures of text.  Which is pretty sad.

+ * 23-Sep-93: got rid of "rint". (David Bagley)
+ * 27-Sep-91: got rid of all malloc calls since there were no calls to free().

+/* Version history as near as I (jwz) can piece together:
+
+   * Carsten Haitzler <raster@redhat.com> wrote the first version in 1996.
+
+   * Rahul Jain <rahul@rice.edu> added support for TrueColor displays.
+
+   * Someone did a rough port of it to use the xscreensaver utility routines
+     instead of creating its own window by hand.
+
+   * Someone (probably Raster) came up with a subsequent version that had
+     a Red Hat logo hardcoded into it.
+
+   * Daniel Zahn <stumpy@religions.com> found that version in 1998, and 
+     hacked it to be able to load a different logo from a PGM (P5) file, 
+     with a single hardcoded pathname.
+
+   * Jamie Zawinski <jwz@jwz.org> found several versions of xflame in
+     March 1999, and pieced them together.  Changes:
+
+       - Correct and fault-tolerant use of the Shared Memory extension;
+         previous versions of xflame did not work when $DISPLAY was remote.
+
+       - Replaced PGM-reading code with code that can read arbitrary XBM
+         and XPM files (color ones will be converted to grayscale.)
+
+       - Command-line options all around -- no hardcoded pathnames or
+         behavioral constants.
+
+       - General cleanup and portability tweaks.

+/*
+**  Helpful definitions for porting xlock modes to xscreensaver.
+**  by Charles Hannum, mycroft@ai.mit.edu
+**
+**  for xlock 2.3 and xscreensaver 1.2, 28AUG92
+**
+**  Modified for xlockmore 3.0 by Anthony Thyssen <anthony@cit.gu.edu.au>
+**  on August 1995.
+**
+**  Tweaked by jwz to work with both ANSI and K&R compilers, 10-May-97.
+**
+**    Note: this file no longer works as of (at least) xlockmore 4.03a10:
+**    see jwz's new xlockmore.h file for a similar hack that works with
+**    code written for that version.
+**
+**  To use, just copy the appropriate file from xlock, add a target
+**  for it in the Imakefile, and do the following:
+**
+**  1) If you include math.h, make sure it is before xlock.h.
+**  2) Make sure the first thing you do in initfoo() is to call
+**     XGetWindowAttributes.  This is what actually sets up the
+**     colormap and whatnot.
+**  3) Add an appropriate PROGRAM() line at the end of the .c file.
+**     The information you need for this comes from xlock's file
+**     resource.c.
+**
+**  That's about all there is to it.
+**
+**  As an added bonus, if you put an empty definition of PROGRAM() in
+**  xlock's xlock.h, you can now use the code with either xlock or
+**  xscreensaver.
+**
+**
+**  If you make any improvements to this code, please send them to me!
+**  It could certainly use some more work.

+/* Lyap - calculate and display Lyapunov exponents */
+
+/* Written by Ron Record (rr@sco) 03 Sep 1991 */
+
+/* The idea here is to calculate the Lyapunov exponent for a periodically
+ * forced logistic map (later i added several other nonlinear maps of the unit
+ * interval). In order to turn the 1-dimensional parameter space of the
+ * logistic map into a 2-dimensional parameter space, select two parameter
+ * values ('a' and 'b') then alternate the iterations of the logistic map using
+ * first 'a' then 'b' as the parameter. This program accepts an argument to
+ * specify a forcing function, so instead of just alternating 'a' and 'b', you
+ * can use 'a' as the parameter for say 6 iterations, then 'b' for 6 iterations
+ * and so on. An interesting forcing function to look at is abbabaab (the
+ * Morse-Thue sequence, an aperiodic self-similar, self-generating sequence).
+ * Anyway, step through all the values of 'a' and 'b' in the ranges you want,
+ * calculating the Lyapunov exponent for each pair of values. The exponent
+ * is calculated by iterating out a ways (specified by the variable "settle")
+ * then on subsequent iterations calculating an average of the logarithm of
+ * the absolute value of the derivative at that point. Points in parameter
+ * space with a negative Lyapunov exponent are colored one way (using the
+ * value of the exponent to index into a color map) while points with a
+ * non-negative exponent are colored differently.
+ *
+ * The algorithm was taken from the September 1991 Scientific American article
+ * by A. K. Dewdney who gives credit to Mario Markus of the Max Planck Institute
+ * for its creation. Additional information and ideas were gleaned from the
+ * discussion on alt.fractals involving Stephen Hall, Ed Kubaitis, Dave Platt
+ * and Baback Moghaddam. Assistance with colormaps and spinning color wheels
+ * and X was gleaned from Hiram Clawson. Rubber banding code was adapted from
+ * an existing Mandelbrot program written by Stacey Campbell.

+.SH DESCRIPTION
+\fIxlyap\fR
+generates and graphically displays an array of Lyapunov exponents for a 
+variety of iterated periodically forced non-linear maps of the unit interval.
+.SH OPTIONS
+.TP 8
+-random
+A good choice for use with xscreensaver: picks random parameters from 
+a built-in list.
+.TP 8
+-C \fIn\fP
+Specifies the minimum color index to be used for negative exponents
+.TP
+-D \fIn\fP
+Specifies the "dwell" or number of iterations over which to average in order
+to calculate the Lyapunov exponent. Default is 400.
+.TP
+-B 
+Causes the stop, go, spin and quit buttons to be displayed.
+.TP
+-H \fIn\fP
+Specifies the height of the window. Default is 256.
+.TP
+-L 
+Indicates use log(x) + log(y) rather than log(xy).
+.TP
+-M \fIr\fP
+Specifies the real value to compare exponent values to for indexing into
+a color wheel. The default value is 1.0.
+.TP
+-O \fIn\fP
+Specifies the minimum color index to be used for positive exponents
+.TP
+-R \fIp\fP
+Specifies pseudo-random forcing with probability \fIp\fP of using parameter
+value 'a'.
+.TP
+-S \fIn\fP
+Specifies the "settle" or number of iterations prior to the beginning of
+the calculation of the Lyapunov exponent. Default is 200.
+.TP
+-W \fIn\fP
+Specifies the width of the window. Default is 256.
+.TP
+-a \fIr\fP
+Specifies the real value to use as the minimum parameter value of the 
+horizontal axis. Default is 3.0 for the logistic map.
+.TP
+-b \fIn\fP
+Specifies the real value to use as the minimum parameter value of the 
+vertical axis. Default is 3.0 for the logistic map.
+.TP
+-c \fIn\fP
+Selects one of six different color wheels to use. The default color
+wheel is a rainbow palette.
+.TP
+-F \fI10101010\fP
+Specifies the "Function" forcing function to use. The example above would 
+alternate between iterating the circle and logistic maps. An argument of
+"-F 2323" would alternate between left and right logistic maps. The default
+is to only use the single specified map (see the description of -m).
+.TP
+-f \fIabbabaab\fP
+Specifies the forcing function to use. The default is to alternate between
+the "a" parameter and the "b" parameter.
+.TP
+-h \fIr\fP
+Specifies the real value to be used as the range over which the vertical
+parameter values vary. The default is 1.0.
+.TP
+-i \fIr\fP
+Specifies the real value of the initial condition to use. Default is 0.05.
+.TP
+-m \fIn\fP
+Selects between available non-linear maps of the unit interval. A value of
+0 specifies the logistic map. A value of 1, the circle map. A value of 2,
+the left-logistic. A value of 3, the right-logistic. A value of 4, the
+double-logistic. The default is 0, the logistic map.
+.TP
+-o \fIfilename\fP
+Specifies the output filename to be used. If the -o option is given, this
+file will automatically be written out at the completion of the drawing.
+If it is not specified, a default filename of lyap.out is used and only
+written if the 'f' or 'F' keys are pressed during a run. The format of the
+output file is PPM for color and PGM for monochrom. The parameters used to
+calculate the picture are included as comments at the beginning of the output
+file.
+.TP
+-p
+Switches color indices for negative and positive exponents. Generally,
+causes negative exponents to be displayed in more detail while darkening
+and narrowing the color range for positive exponents. This can be toggled
+during runtime by pressing the 'p' key.
+.TP
+-r \fIn\fP
+Specifies the maximum rgb value to be used. Default is 35000.
+.TP
+-s \fIn\fP
+Specifies the length of the color wheel spin.
+.TP
+-u
+Produces a usage message.
+.TP
+-v 
+Prints out the various values to be used and exits.
+.TP
+-w \fIr\fP
+Specifies the real value to be used as the range over which the horizontal
+parameter values vary. The default is 1.0.
+.TP
+-x \fIn\fP
+Specifies the x screen coordinate of the window (default is 256).
+.TP
+-y \fIn\fP
+Specifies the y screen coordinate of the window (default is 256).
+.sp 2
+.SH NOTES
+.sp
+During display, pressing any mouse button allows you to select the area to
+be investigated with the mouse. The upper left hand corner of the desired
+area is the location of the cursor when the button is pressed. The lower
+right hand corner is specified by the cursor when the button is released.

+The algorithm was taken from the September 1991 Scientific American article
+by A. K. Dewdney who gives credit to Mario Markus of the Max Planck Institute
+for its creation. Additional information and ideas were gleaned from the
+discussion on alt.fractals involving Stephen Hall, Ed Kubaitis, Dave Platt
+and Baback Moghaddam. Assistance with colormaps and spinning color wheels
+and X was gleaned from Hiram Clawson. Rubber banding code was adapted from
+an existing Mandelbrot program written by Stacey Campbell.
+
+Viciously hacked for xscreensaver by Jamie Zawinski, 20-Nov-97.

+.TH XScreenSaver 1 "22-mar-93" "X Version 11"
+.SH NAME
+xroger - throbbing X logo, of a sort
+.SH SYNOPSIS
+.B xroger
+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP]
+.SH DESCRIPTION
+The \fIxroger\fP program displays a replacement for the X logo with a more
+accurate Look and Feel.
+.SH OPTIONS
+.I xroger
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mono 
+If on a color display, pretend we're on a monochrome display.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use.  Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.SH BUGS
+It should also drip blood while making a horrible screeching noise.

+/* This is a kludge that lets xscreensaver work with SGI demos that expect
+   to be run from `haven'.  It runs the program given on the command line,
+   then waits for an X window to be created whose name is that of the 
+   program.  Then, it resizes that window to fill the screen.  Run it
+   like this:
+
+       xscreensaver-sgigl /usr/demos/bin/ep -S
+       xscreensaver-sgigl -n ant /usr/demos/General_Demos/ant/RUN
+       xscreensaver-sgigl -n atlantis /usr/demos/General_Demos/atlantis/RUN
+       xscreensaver-sgigl -n /usr/demos/General_Demos/powerflip/powerflip \
+          /usr/demos/General_Demos/powerflip/RUN
+
+   Except that doesn't really work.  You have to do this instead:
+
+       xscreensaver-sgigl -n ant ant.sh
+
+   where ant.sh contains
+
+       #!/bin/sh
+       cd /usr/demos/General_Demos/ant
+       exec ./ant -S
+
+   There's no way to make this work with powerflip at all, since it doesn't
+   take a -S option to run in the foreground.
+ */
+
+/* #### Another way to do this would be:
+   instead of exec'ing the hack, fork it; then wait for that fork to die.
+   If it dies, but the window ID is still valid, then that means the 
+   sub-process has forked itself (as those fuckwits at SGI are wont to do.)
+   In that case, this process should go to sleep, and set up a signal handler
+   that will destroy the X window when it is killed.  That way, the caller
+   is given a foreground pid which, when killed, will cause the hack to die
+   (by a roundabout mechanism.)
+
+   This would all be so much simpler if those assholes would just:
+
+   1: get out of the habit of writing programs that magically background
+      themselves, and
+
+   2: give the fucking programs arguments which control the window size
+      instead of always making 100x100 windows!
+
+   I won't even dream of having a "-root" option that understood virtual-roots;
+   that would just be too outlandish to even dream about.

-! Turning on "installColormap" interacts erratically with twm and tvtwm,
-! but seems to work fine with mwm and olwm.  Try it and see.  If your

-
-! Any program which can draw on the root window will work as a screensaver.
-! The following resource enumerates them.
-!
-! Programs are separated by newlines (specified in resource files with \n).
-! Lines may be continued with a lone \ at the end of the line.
-!
-! Each line is an `sh' command.
-!
-! If the first (non-blank) character on the line is "-", then that means
-! that this command is disabled: it's still in the list, but it won't ever
-! be used.  (This is just to make it easy to disable and then re-enable 
-! them later.)
-!
-! If the first word on the line is the name of a visual followed by a
-! colon, then that visual will be used for the program, if it is available.
-! If no such visual is available, then the program will be skipped.  In
-! this way, you can specify that you want certain programs to run only
-! on color screens, and others only on mono screens, by making use of the
-! magic visual names "color" and "mono".  Likewise, if some hacks prefer
-! colormaps, but others prefer 24-bit windows, that also can be arranged
-! (in this case, by using "PseudoColor:" versus "TrueColor:".)
-!
-! Some of the screenhacks are written using OpenGL.  OpenGL programs are
-! a bit different than normal X programs, in that they prefer visuals that
-! are *half* as deep as the screen.  You can tell xscreensaver to select a
-! good visual for a GL program by using the magic visual name "GL".
-!
-! All programs must be launched in such a way that they draw on the root
-! window; they should not be spawned in the background with "&".  If shell
-! metacharacters are used, they must be understandable to `sh', not `csh'
-! (the $SHELL variable is not consulted, for unfortunate but good reasons.)
-!
-! Be sure to check out Demo Mode: run the `xscreensaver-demo' program to
-! edit the current list of programs interactively, try out the various modes,
-! and change other parameters.  See the man page for details.

-! xtacy is ok, but it only works on the default visual.  We can satisfy
-! that constraint like so:
-!
-!     default: xtacy -root -delay 100 -funky -number 3                 \n\
-!     default: xtacy -root -delay 100 -gravity                         \n\
-!     default: xtacy -root -delay 100 -mixer                           \n\
-!     default: xtacy -root -delay 100 -taffy -pal 4                    \n\
-! 
-! To display a randomized slideshow of images, you can do something like this:
-!
-!     default-n:  xv -root -rmode 5 -random -viewonly -wloop              \
-!                    -wait 30 $HOME/bitmaps/*.jpg                       \n\
-!
-! Note that we've used "default-n" as the visual name, rather than just
-! "default": this means "default visual, no install", that is, it's like
-! specifying the command-line arguments "-visual default -no-install".
-! This is necessary because, when XV is running in "-root" mode, it always
-! assumes that the default visual and colormap are being used, rather than 
-! examining the window it is drawing on to see what visual and colormap it
-! has.  If we didn't force the default visual to be used, xv would get an
-! X error.  If we didn't force the default colormap to be installed, the
-! colors would be all wrong.  "default-i" may also be used as a visual name
-! (meaning, "-visual default -install") but you probably won't ever need
-! to use that.
-!
-! XEarth is nice, too:
-!
-!     default-n: xearth -nostars -wait 0 -timewarp 400 -pos sunrel/38/-30
-!
-!
-! Some of the GL demos that SGI ships work with XScreenSaver; most don't.
-! XScreenSaver includes a program (not built or installed by default)
-! called "xscreensaver-sgigl".  To use the SGI demos with XScreenSaver,
-! build that program, and use it to launch the SGI demos.  For example,
-! on Irix 6.2, you can do this:
-!
-!     xscreensaver-sgigl /usr/demos/bin/ep -S
-!     xscreensaver-sgigl /usr/demos/bin/bongo
-!
-! On Irix 6.3, things have moved, so you need to do it like this:
-!
-!     xscreensaver-sgigl /usr/sbin/ep -S
-!
-! You can also use the "ant" demo, but first you need to wrap a shell script
-! around it that cds to its home directory, so that it can find its files;
-! and also pass it the -S argument, to prevent it from forking.
-!
-!
-! Also, since these actually end up mapping their own windows instead of
-! drawing on the XScreenSaver-provided root, when they are being run from
-! demo-mode, you can't pop up the demo-mode dialog just by clicking the
-! mouse: you must first type ESC to make the SGI programs exit.  This sucks.
-! Things should work properly when they are being run by xscreensaver in
-! non-demo-mode, however.
-!
-! Basically, the SGI demo writers went out of their way to make my life hell.

-       The _\ba_\bt_\bt_\br_\ba_\bc_\bt_\bi_\bo_\bn  program  has  several  visually  different
-       modes of operation, all of which are based on the interac-
-       tions of a set of control points which attract each  other
-       up  to  a  certain  distance, and then begin to repel each
-       other.  The attraction/repulsion is  proportional  to  the
-       distance between any two particles.

-
-       -\b-r\bro\boo\bot\bt   Draw on the root window.
-
-       -\b-m\bmo\bon\bno\bo   If  on  a  color  display,  pretend  we're  on   a
-               monochrome display.

-
-               In _\bl_\bi_\bn_\be_\bs mode, the control points are connected by
-               straight lines; the effect is something like  _\bq_\bi_\bx.
-
-               In _\bp_\bo_\bl_\by_\bg_\bo_\bn_\bs mode, the control points are connected
-               by straight lines, and filled in.   This  is  most
-               interesting in color.
-
-               In  _\bs_\bp_\bl_\bi_\bn_\be_\bs  mode, a closed spline is interpolated
-               from the control points.
-
-               In _\bf_\bi_\bl_\bl_\be_\bd_\b-_\bs_\bp_\bl_\bi_\bn_\be_\bs mode, the splines are filled  in
-               instead of being outlines.  This is most interest-
-               ing in color.
-
-               In _\bt_\ba_\bi_\bl_\bs mode, the path which each  particle  fol-
-               lows  is  indicated  by  a  worm-like trail, whose
-               length is controlled by the _\bs_\be_\bg_\bm_\be_\bn_\bt_\bs parameter.

-       -\b-s\bsi\biz\bze\be i\bin\bnt\bte\beg\bge\ber\br
-               The size of the balls in pixels, or 0, meaning  to
-               select  the sizes randomly (the default.)  If this
-               is specified, then all  balls  will  be  the  same
-               size.   This  option  has  an effect in all modes,
-               since the ``size'' of  the  balls  controls  their
-               mass.

-               line segments or polygons should be drawn. Default
-               100.   This  has no effect in _\bb_\ba_\bl_\bl_\bs mode.  If _\bs_\be_\bg_\b-
-               _\bm_\be_\bn_\bt_\bs is 0, then no segments will ever  be  erased

-
-       -\b-d\bde\bel\bla\bay\by m\bmi\bic\bcr\bro\bos\bse\bec\bco\bon\bnd\bds\bs
-               How  much  of a delay should be introduced between

-               If  on a color display, the color of the line seg-
-               ments or polygons will  cycle  through  the  color
-               map.   This specifies how many lines will be drawn
-               before a new color is chosen.  (When a small  num-
-               ber of colors are available, increasing this value
-               will  yield  smoother  transitions.)   Default  3.

-               the  points  will  vary according to their current

-               flare  brighter  when  they  are  reacting to each
-               other most strongly.
-
-               In _\bg_\bl_\bo_\bw mode, all of the balls will be  drawn  the
-               same (random) color, modulo the saturation shifts.
-               In non-glow mode, the balls will each be drawn  in
-               a random color that doesn't change.

-
-       -\b-o\bor\brb\bbi\bit\bt  Make the initial force on each ball be  tangential
-               to  the circle on which they are initially placed,
-               with the right velocity  to  hold  them  in  orbit
-               about  each other.  After a while, roundoff errors

-

-               In orbit mode, the initial velocity of  the  balls
-               is  multiplied  by this; a number less than 1 will
-               make the balls pull closer together, and a  larger
-               number  will make them move apart.  The default is
-               0.9, meaning a slight inward pull.
-
-       -\b-v\bvi\bis\bsc\bco\bos\bsi\bit\bty\by f\bfl\blo\boa\bat\bt
-               This sets the viscosity of the hypothetical  fluid
-               through which the control points move; the default
-               is 1, meaning no resistance.  Values higher than 1
-               aren't   interesting;   lower  values  cause  less
-               motion.

-               Give it a few seconds to settle down into a stable
-               clump,  and then move the mouse through it to make
-               "waves".
-
-       -\b-m\bmo\bou\bus\bse\be  This will cause the mouse to be considered a  con-
-               trol  point;  it  will  not  be drawn, but it will
-               influence the other points, so you  can  wave  the

-       The _\bb_\bl_\bi_\bt_\bs_\bp_\bi_\bn program repeatedly rotates  a  bitmap  by  90
-       degrees by using logical operations: the bitmap is divided
-       into quadrants, and the quadrants are  shifted  clockwise.
-       Then  the  same  thing  is  done  again with progressively
-       smaller quadrants, except  that  all  sub-quadrants  of  a
-       given  size  are  rotated  in  parallel.   So  this  takes
-       O\bO(\b(1\b16\b6*\b*l\blo\bog\bg2\b2(\b(N\bN)\b))\b) blits of size NxN, with the limitation  that
-       the  image must be square, and the size must be a power of
-       2.

-               The file name of a bitmap to rotate.  It need  not

-
-       v\bvi\bid\bde\beo\boD\bDe\bev\bvi\bic\bce\be (Integer)

-               (from videopanel(1)) will be checked first.  After
-               that, all other available video input devices will
-               be checked in order.
-
-               The  first  one  which  produces a non-black image
-               will be used.  If all images are black, the others

-       Unlike the systems that the images are borrowed from, _\bb_\bs_\bo_\bd
-       does not require a reboot after running.
-
-       _\bb_\bs_\bo_\bd should also emulate more systems,  but  systems  with
-       interesting  crash graphics are not as common as one might
-       hope.
-
-       One I'd really like to see is a Unix system getting a ker-
-       nel panic, rebooting, and running f\bfs\bsc\bck\bk(8).

-       _\bB_\bu_\bb_\bb_\bl_\be_\bs sprays lots of little random bubbles all over  the
-       window which then grow until they reach their maximum size
-       and go pop.  The inspiration for this was watching  little
-       globules  of oil on the bottom of a frying pan and it also
-       looks a little like bubbles  in  fizzy  soft  drink.   The
-       default  mode  uses  fancy ray-traced bubbles but there is
-       also a mode which just draws circles in case  the  default
-       mode is too taxing on your hardware.

-       Depending on how your _\bb_\bu_\bb_\bb_\bl_\be_\bs was compiled, it accepts the

-               name  of a visual class, or the id number (decimal
-               or hex) of a specific visual.
-
-       -\b-d\bde\bel\bla\bay\by m\bmi\bic\bcr\bro\bos\bse\bec\bco\bon\bnd\bds\bs
-               How much of a delay should be  introduced  between
-               steps  of  the  animation.   Default 1, or about 1
-               microsecond.  Actually, this is the delay  between
-               each  group  of  15 new bubbles since such a delay
-               between each step results in a very slow animation
-               rate.

-
-       -\b-s\bsi\bim\bmp\bpl\ble\be Don't  use the default fancy pixmap bubbles.  Just
-               draw circles instead.  This may give more bearable
-               performance  if your hardware wasn't made for this
-               sort of thing.
-
-       -\b-b\bbr\bro\bok\bke\ben\bn Don't hide bubbles when they pop.  This was a  bug
-               during  development  but the results were actually
-               quite attractive.  (This option is only  available
-               if  you  have  the  XPM  library available and the
-               imake generated Makefile has defined HAVE_XPM).
-
-       -\b-3\b3D\bD     Normally, the simulation is done completely in two
-               dimensions.   When  a  bubble  swallows up another
-               bubble, the areas of each are  added  to  get  the
-               area of the resulting bubble.  This option changes
-               the algorithm to  instead  add  volume  (imagining
-               each to be a sphere in 3D space).  The whole thing
-               looks more realistic but I find it attracts atten-
-               tion  to the flickering of each bubble as they are
-               move and are redrawn.  Your mileage may vary.

-               Use the pixmap  definitions  in  the  given  file,
-               instead  of  the  default (if one is compiled in).
-               This is ignored if _\b-_\bs_\bi_\bm_\bp_\bl_\be is specified.   If  the
-               file is compressed (either with compress or gzip),
-               it is decompressed before use.  (This option  only
-               works  if  you  have XPM compiled into your binary
-               and you have compiled with BUBBLES_IO set in  bub-
-               bles.h.  This is n\bno\bot\bt the default).

-               Similar to _\b-_\bf_\bi_\bl_\be except the file is taken randomly
-               from the  contents  of  the  specified  directory.
-               (Again,  this option is only available if you have
-               XPM and BUBBLES_IO was set  when  compiling.   See
-               above).
-
-       -\b-q\bqu\bui\bie\bet\bt  Don't print messages explaining why one or several
-               command line options were ignored.  This  is  dis-
-               abled by default.
-
-N\bNO\bOT\bTE\bES\bS
-       If  you  find  the  pace of things too slow, remember that
-       there is a delay even though you specify no _\b-_\bd_\be_\bl_\ba_\by option.
-       Try using _\b-_\bn_\bo_\bd_\be_\bl_\ba_\by although beware of the effects of irri-
-       tation of other users if you're on a shared system as  you

-       scripts to a permanent location and use them.   Read  bub-
-       bles.README.
-
-       Rendered bubbles are not supported on monochrome displays.
-       I'm not convinced that small bubbles, even dithered  prop-
-       erly are going to look like anything more than a jumble of
-       random dots.
-
-B\bBU\bUG\bGS\bS
-       There is a delay before something appears  on  the  screen
-       when  using  rendered  bubbles.   The XPM library seems to
-       take a l\blo\bon\bng\bg time to make pixmaps out of  raw  data.   This
-       can be irritating on slower systems.
-
-       The  movement  of the bubbles looks jerky if an incomplete
-       set of bubbles is used.
-
-       The hide/display algorithm could  do  with  some  work  to
-       avoid flickering when _\b-_\bn_\bo_\bd_\be_\bl_\ba_\by is set.

-       The  _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl  program displays a self-organizing critical
-       system that gradually emerges from chaos.
-
-       _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl performs a simulation on a two-dimensional  array
-       of  integers.   The array is initialized to random values.
-       On each iteration, it draws a line to the  array  position
-       with  the  greatest value.  It then replaces that location
-       and the eight neighboring locations with randomly-selected
-       values.
-
-       The  lines  are  initially random, but over time a chaotic
-       self-organizing system evolves: areas of the screen  which
-       happen  to have lower values are less likely to be updated
-       to new values, and so the line tends to avoid those areas.
-       Eventually, the histogram of changes approaches the power-
-       law curve typical of such systems.
-
-       The simplest documented self-organizing system is the one-
-       dimensional equivalent of _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl.
-
-       I heard about this algorithm second-hand: apparently there
-       was an article in _\bS_\bc_\bi_\be_\bn_\bt_\bi_\bf_\bi_\bc _\bA_\bm_\be_\br_\bi_\bc_\ba_\bn describing it  some-

-               The  first  one  which  produces a non-black image

-       The  epicycle program draws the path traced out by a point
-       on the edge of a circle.  That  circle  rotates  around  a
-       point  on  the  rim  of another circle, and so on, several
-       times.  The random curves produced can be simple  or  com-
-       plex, convex or concave, but they are always closed curves
-       (they never go in indefinitely).
-
-       You can configure both the way the curves  are  drawn  and
-       the  way in which the random sequence of circles is gener-
-       ated, either with command-line options or X resources.

-               Decreasing this value will reduce the distance the

-               ing  a smoother figure.  Increasing it may produce

-               Each epicycle rotates at a rate which is a  factor
-               of  the base speed.  The speed of each epicycle is
-               the base speed divided by some integer  between  1
-               and  the  value  of  the  -\b-h\bha\bar\brm\bmo\bon\bni\bic\bcs\bs option.  This
-               integer is decided by starting at 1 and tossing  a
-               biased coin.  For each consecutive head, the value
-               is incremented by one.  The integer  will  not  be
-               incremented  above  the  value  of  the -\b-h\bha\bar\brm\bmo\bon\bni\bic\bcs\bs
-               option.  The argument of this option  decides  the
-               bias  of the coin; it is the probability that that
-               coin will produce a head at any given toss.

-       The  program  runs  mostly without user interaction.  When
-       running on the root window, no input  is  accepted.   When
-       running  in its own window, the program will exit if mouse
-       button 3  is  pressed.   If  any  other  mouse  button  is
-       pressed,  the current figure will be abandoned and another

-       The geometry of epicycles was perfected by  Hipparchus  of
-       Rhodes  at  some time around 125 B.C., 185 years after the
-       birth of Aristarchus of Samos, the inventor of the  helio-
-       centric  universe  model.  Hipparchus applied epicycles to
-       the Sun and the Moon.  Ptolemy of Alexandria  went  on  to
-       apply  them to what was then the known universe, at around
-       150 A.D.  Copernicus went on to apply them to  the  helio-
-       centric  model  at the beginning of the sixteenth century.
-       Johannes Kepler discovered that the planets actually  move
-       in  elliptical  orbits  in about 1602.  The inverse-square
-       law of gravity was suggested by Boulliau in  1645.   Isaac
-       Newton's  _\bP_\br_\bi_\bn_\bc_\bi_\bp_\bi_\ba _\bM_\ba_\bt_\bh_\be_\bm_\ba_\bt_\bi_\bc_\ba was published in 1687, and
-       proved that Kepler's laws derived from Newtonian  gravita-
-       tion.

-               Sets the algorithm that will be used  to  generate
-               the  mazes.  The  default  is  -1,  which randomly
-               selects an algorithm for each maze that is  gener-
-               ated.  Generator  0 is the original one, and works
-               by walking around randomly until we  hit  a  place
-               we've  been before, then backtracking and trying a
-               new direction somewhere. Generator 1 picks a  ran-
-               dom  spot  in the maze, then draws a straight wall
-               from that spot in a random direction until it hits
-               another wall (and continues until the maze is com-
-               plete). Generator 2 is based  on  sets.  Initially
-               all  cells  are in different sets. Then two neigh-
-               boring cells are chosen and if they are in differ-
-               ent  sets,  their sets are joined. If they were in
-               the same set, a wall is built between  them.  This
-               continues until the maze is complete.
-
-               All  generators  generate  mazes  with  a  certain
-               'characteristic'. See if you can spot them!

-       The _\bm_\bu_\bn_\bc_\bh program preforms the munching squares hack until
-       killed.   It picks square size, position, and gravity ran-
-       domly; configurable options are listed below.
-
-       The munching squares hack cosists of drawing Y = X  XOR  T
-       for  a range of X and T over and over until all the possi-
-       ble combinations of X and T have come up.  It was  report-
-       edly  discovered  by  Jackson  Wright  in  1962 and took 5
-       instructions of PDP-6 code.

-       The _\bp_\be_\bn_\br_\bo_\bs_\be program draws quasiperiodic tilings.
-
-       See  Onoda,  Steinhardt,  DiVincenzo  and Socolar in Phys.
-       Rev. Lett. 60, #25, 1988 or  Strandburg  in  Computers  in
-       Physics, Sep/Oct 1991.
-
-       This implementation uses the simpler version of the growth
-       algorithm, i.e., if there are no forced vertices,  a  ran-
-       domly chosen tile is added to a randomly chosen vertex (no
-       preference for those 108 degree angles).
-
-       There are two essential differences to the algorithm  pre-
-       sented  in  the  literature:  First,  we  do not allow the
-       tiling to enclose an untiled area.  Whenever  this  is  in
-       danger  of  happening, we just do not add the tile, hoping
-       for a better random choice the next  time.   Second,  when
-       choosing  a  vertex  randomly,  we will take one that lies
-       withing the viewport if available.  If this seems to cause
-       enclosures  in the forced rule case, we will allow invisi-
-       ble vertices to be chosen.
-
-       Tiling is restarted whenever one of the following happens:
-       there  are  no  incomplete vertices within the viewport or
-       the tiling has extended a window's length beyond the  edge
-       of  the  window  horizontally or vertically or forced rule
-       choice has failed 100 times due to areas about  to  become
-       enclosed.
-
-       Although  quasiperiodic  tilings  are  produced, the tiles
-       themselves are not penrose tiles  (darts  and  kites).  In
-       contrast  to penrose tiles, these tiles can be arranged to
-       form a periodic tiling.

-       The  _\bq_\bi_\bx  program bounces a series of line segments around
-       its window.  This is truly the swiss army chainsaw of  qix
-       programs.   If  you know of one with more display modes, I
-       want to know about it.
-
-O\bOP\bPT\bTI\bIO\bON\bNS\bS
-       _\bq_\bi_\bx accepts the following options:
-
-       -\b-w\bwi\bin\bnd\bdo\bow\bw Draw on  a  newly-created  window.   This  is  the
-               default.
-
-       -\b-r\bro\boo\bot\bt   Draw on the root window.
-
-       -\b-m\bmo\bon\bno\bo   If   on  a  color  display,  pretend  we're  on  a
-               monochrome display.
-
-       -\b-i\bin\bns\bst\bta\bal\bll\bl
-               Install a private colormap for the window.
-
-       -\b-v\bvi\bis\bsu\bua\bal\bl _\bv_\bi_\bs_\bu_\ba_\bl
-               Specify which visual to use.  Legal values are the
-               name  of a visual class, or the id number (decimal
-               or hex) of a specific visual.
-
-       -\b-s\bse\beg\bgm\bme\ben\bnt\bts\bs _\bi_\bn_\bt_\be_\bg_\be_\br
-               How many line segments should be  drawn.   Default
-               50.
-
-       -\b-s\bsp\bpr\bre\bea\bad\bd _\bi_\bn_\bt_\be_\bg_\be_\br
-               How  far apart the endpoints of one segment should
-               be from the next.  Default 8.
-
-       -\b-s\bsi\biz\bze\be _\bi_\bn_\bt_\be_\bg_\be_\br
-               The maximum distance one endpoint of a segment  is
-               allowed  to  be from the opposite end of that seg-
-               ment.  Default 0, meaning unlimited.
-
-       -\b-c\bco\bou\bun\bnt\bt _\bi_\bn_\bt_\be_\bg_\be_\br
-               How many qixes to draw.  Default 1.

-
-       -\b-c\bco\bol\blo\bor\br-\b-s\bsh\bhi\bif\bft\bt _\bd_\be_\bg_\br_\be_\be_\bs
-               If on a color display, the color of the line  seg-
-               ments will cycle through the spectrum.  This spec-
-               ifies how far the hue of each  segment  should  be
-               from  the  next,  in  degrees  on  the  HSV wheel.
-               Default 3.
-
-       -\b-d\bde\bel\bla\bay\by _\bm_\bi_\bc_\br_\bo_\bs_\be_\bc_\bo_\bn_\bd_\bs
-               How much of a delay should be  introduced  between
-               steps  of  the animation.  Default 25000, or about
-               0.025 seconds.
-
-       -\b-r\bra\ban\bnd\bdo\bom\bm The _\bq_\bi_\bx will wander around  the  screen  semi-ran-
-               domly.  This is the default.
-
-       -\b-l\bli\bin\bne\bea\bar\br The  opposite  of  _\b-_\br_\ba_\bn_\bd_\bo_\bm: the _\bq_\bi_\bx will travel in
-               straight lines until it reaches a wall,  and  then
-               it will bounce.
-
-       -\b-s\bso\bol\bli\bid\bd  If  this  is  specified, then the area between the
-               line segments will be filled in with the appropri-
-               ate  color,  instead  of the _\bq_\bi_\bx simply being com-
-               posed  of  one-pixel-wide  line  segments.    This
-               option looks really good in color.
-
-       -\b-h\bho\bol\bll\blo\bow\bw The opposite of _\b-_\bs_\bo_\bl_\bi_\bd; this is the default.
-
-       -\b-x\bxo\bor\br    If  this  is  specified, then qix segments will be
-               drawn and erased with xor, instead of being  drawn
-               in  some color and erased in the background color.
-               This implies _\b-_\bm_\bo_\bn_\bo, in that only two colors can be
-               used.
-
-       -\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
-               If  this  is specified, and _\b-_\bc_\bo_\bu_\bn_\bt is greater than
-               1, then each qix will be drawn in one  color,  and
-               when they overlap, the colors will be mixed.  This
-               looks best in conjuction with _\b-_\bs_\bo_\bl_\bi_\bd.
-
-       -\b-n\bno\bon\bn-\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
-               Turns off _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt.
-
-       -\b-a\bad\bdd\bdi\bit\bti\biv\bve\be
-               If _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt is  specified,  then  this  option
-               means that the colors will be mixed using an addi-
-               tive color model, as if the qixes  were  projected
-               light.  This is the default.
-
-       -\b-s\bsu\bub\bbt\btr\bra\bac\bct\bti\biv\bve\be
-               If  _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt  is  specified,  then this option
-               means that the colors will be mixed using  a  sub-
-               tractive   color  model,  as  if  the  qixes  were
-               translucent filters.

-               How many vertices each qix-line should  have:  the

-       The _\br_\bd_\b-_\bb_\bo_\bm_\bb  program  draws  reaction/diffusion  textures.
-       The code is derived from the 'd' mode of the "bomb" visual
-       musical                  instrument                   (see
-       http://www.cs.cmu.edu/~spot/bomb.html).   I  got the equa-
-       tions      from       xmorphia       (http://www.ccsf.cal-
-       tech.edu/ismap/image.html), which is based on a version of
-       the Gray-Scott model taken from:
-           John E. Pearson "Complex Patterns in a Simple System"
-           Science, 261,189, 9 July 1993.
-
-       If the frame-rate is  too  low,  consider  decreasing  the
-       width  and  height  of the tile, or decreasing the size of
-       the active part of the screen.

-       The _\br_\bo_\bc_\bk_\bs program draws an animation of an asteroid  field
-       moving  past  the observer (or vice versa).  Sometimes the
-       observer picks up spin on Z axis.

-
-       -\b-s\bsp\bpe\bee\bed\bd _\bi_\bn_\bt_\be_\bg_\be_\br
-               A measure of the speed with which the observer and
-               the rocks pass each other, from 1 to 100.  Default
-               100,  meaning  ``very fast.''  If you're on a slow
-               display connection  (the  animation  looks  jerky)
-               then   try  making  this  number  smaller,  and/or
-               decreasing the number of rocks.
-
-       -\b-d\bde\bel\bla\bay\by _\bm_\bi_\bc_\br_\bo_\bs_\be_\bc_\bo_\bn_\bd_\bs
-               Number  of  microseconds  to  delay  between  each
-               frame.   Default  50000, meaning about 1/20th sec-
-               ond.  Compare and contrast with _\b-_\bs_\bp_\be_\be_\bd, above.

-       The _\bs_\bo_\bn_\ba_\br program displays a sonar scope on the computer's
-       screen.  This scope polls  a  sensor  as  the  sweep  goes
-       around  the  scope and displays what it finds as bogies on
-       the screen.  The program is designed to support  different
-       modes  representing different types of sensors.  Currently
-       the only implemented sensors are a simulator, and  a  net-
-       work  ping function that pings hosts and plots the results
-       on the scope.

-
-       -\b-g\bgr\bri\bid\bd-\b-c\bco\bol\blo\bor\br _\bC_\bo_\bl_\bo_\br

-
-       -\b-t\bte\bex\bxt\bt-\b-c\bco\bol\blo\bor\br _\bC_\bo_\bl_\bo_\br

-       Time  3D  is  a clock. It uses flying balls to display the
-       time. This balls move and wobble around to  give  you  the
-       impression  your graphic workstation with its many XStones
-       is doing something.
-
-       t3d uses mouse and keyboard to let  you  fly  through  the
-       balls. Hit S\bS to speed up, A\bA to slow down, Z\bZ to zoom in and
-       X\bX to zoom out.  Use the l\ble\bef\bft\bt m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to rotate to the
-       left  and the r\bri\big\bgh\bht\bt m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to rotate the view to the
-       right. Use the m\bmi\bid\bdd\bdl\ble\be m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to change  the  optical
-       axis and the moving direction.  0\b0 (zero) will stop you.  Q\bQ

-              Modifies the wobbling (sounds nice :-)  of  t3d  by

-
-       -\b-m\bma\bag\bg _\bf_\ba_\bc_\bt_\bo_\br
-              Changes  the  magnification of t3d. By default, t3d
-              draws a 200x200 image.  A .I factor of 2 means,  it
-              will use a 400x400 image.

-              Sets   the  moving  cycle  to  _\bp_\be_\br_\bi_\bo_\bd  seconds.  By

-              Inserts a wait after drawing one view of the clock.
-              By  default,  t3d  waits  40 ms after each drawing.
-              This helps you to keep the performance loss  small.

-              t3d  uses  bitmap copy to draw precalculated balls.

-       T3D is  not  related  to  T3D(tm),  the  massive  parallel
-       Alpha--based  supercomputer from Cray Research. T3D's name
-       was invented in 1991, years before  the  project  at  Cray
-       Research  started. There is no relation from T3D to Cray's
-       T3D, even  the  balls  surrounding  T3D  on  some  posters
-       weren't  an  inspiration  for  T3D.  I don't know anything
-       about the other way round.

-       The _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be program pulls random image off of the World
-       Wide  Web  and scatters them on the root window.  It finds
-       these images by doing random web searches, and  extracting
-       images  from  the returned pages.  It places the images on
-       the root window  by  using  the  x\bxv\bv(1),  g\bgi\bif\bft\bto\bop\bpn\bnm\bm(1),  and
-       d\bdj\bjp\bpe\beg\bg(1) tools.
-
-       _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be also works as a CGI program: simply make a sym-
-       bolic link to the _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be executable called _\bn_\bp_\bh_\b-_\bw_\be_\bb_\bc_\bo_\bl_\b-
-       _\bl_\ba_\bg_\be_\b._\bc_\bg_\bi.   If this program sees that it is being run as a
-       CGI, then it will behave  appropriately.   (The  generated
-       web  page  will  list the images one after another, rather
-       than tiling them together.)
-
-       _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be is written in p\bpe\ber\brl\bl(1) and requires Perl 5.
-
-O\bOP\bPT\bTI\bIO\bON\bNS\bS
-       _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be accepts the following options:
-
-       -\b-r\bro\boo\bot\bt   Draw on the root window.  This  option  is  mandi-
-               tory: drawing to a window other than the root win-
-               dow is not yet supported.
-
-       -\b-v\bve\ber\brb\bbo\bos\bse\be or -\b-v\bv
-               Print diagnostics to stderr.  Multiple _\b-_\bv switches
-               increase  the amount of output.  _\b-_\bv will print out
-               only the URLs of the images; _\b-_\bv_\bv  will  print  all
-               the  commands  being run; and _\b-_\bv_\bv_\bv will print more
-               than you care about.
-
-       -\b-d\bde\bel\bla\bay\by _\bs_\be_\bc_\bo_\bn_\bd_\bs
-               How long to sleep between images.  Default 1  sec-
-               ond.   (Remember that this program probably spends

-       The _\bj_\bu_\bl_\bi_\ba  program  draws  spinning,  animating  julia-set
-       fractals.
-
-       It  uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random
-       iteration to plot the julia set, and sinusoidially  varied
-       parameters  for  the set, and plots parameters with a cir-
-       cle.
-
-       One thing to note is that count is the _\bd_\be_\bp_\bt_\bh of the search
-       tree,  so the number of points computed is (2^count)-1.  I
-       use 8 or 9 on a dx266 and it looks okay.   The  sinusoidal
-       variation  of the parameter might not be as interesting as
-       it could, but it still gives an idea of the effect of  the
-       parameter.

-       _\bj_\bu_\bl_\bi_\ba accepts the following options:
-

-               Specify which visual to use.  Legal values are the
-               name of a visual class, or the id number  (decimal
-               or hex) of a specific visual.
-
-       -\b-n\bnc\bco\bol\blo\bor\brs\bs _\bi_\bn_\bt_\be_\bg_\be_\br
-               How  many  colors  should  be  used (if possible).
-               Default 200.  The colors used  cycle  through  the
-               hue, making N stops around the color wheel.

-               tic.  A  value  of  4,  the  double-logistic.  The
-               default is 0, the logistic map.
-
-       -o _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
-               Specifies  the  output filename to be used. If the

-               If it is not  specified,  a  default  filename  of
-               lyap.out  is  used  and only written if the 'f' or
-               'F' keys are pressed during a run. The  format  of
-               the  output  file  is  PPM  for  color and PGM for
-               monochrom. The parameters used  to  calculate  the

-
-       -p      Switches color indices for negative  and  positive
-               exponents. Generally, causes negative exponents to
-               be displayed in more detail  while  darkening  and
-               narrowing  the color range for positive exponents.
-               This can be toggled during runtime by pressing the
-               'p' key.

-
-       x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) has a client-server  model:  the  xscreen-
-       saver  process is a daemon that runs in the background; it

-               When the _\b-_\bd_\be_\bm_\bo option is followed by  an  integer,
-               it  instructs  the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon to run that

-               before  deactivating  (i.e., mouse motion does not

-
-                    sleep 5 ; xscreensaver-command -activate
-
-               to be sure that you have time to  take  your  hand
-               off  the  mouse  before  the screensaver comes on.
-               (Because if you  jiggle  the  mouse,  xscreensaver
-               will notice, and deactivate.)
-
-       -\b-d\bde\bea\bac\bct\bti\biv\bva\bat\bte\be
-               If  the  screensaver  is  active  (the  screen  is
-               blanked), this command will deactivate it just  as
-               if  there had been keyboard or mouse activity.  If
-               locking is  enabled,  then  the  screensaver  will
-               prompt for a password as usual.

-       -\b-c\bcy\byc\bcl\ble\be  If  the  screensaver  is  active  (the  screen  is
-               blanked), then stop the current graphics demo  and
-               run a new one (chosen randomly.)
-
-       -\b-n\bne\bex\bxt\bt   This is like either _\b-_\ba_\bc_\bt_\bi_\bv_\ba_\bt_\be or _\b-_\bc_\by_\bc_\bl_\be, depending
-               on which is  more  appropriate,  except  that  the
-               graphics  hack that will be run is the next one in
-               the list, instead of a  randomly-chosen  one.   In
-               other words, repeatedly executing -next will cause
-               the xscreensaver process to invoke  each  graphics
-               demo sequentially.  (Though using the _\b-_\bd_\be_\bm_\bo option
-               is probably an easier way to accomplish that.)
-
-       -\b-p\bpr\bre\bev\bv   This is like _\b-_\bn_\be_\bx_\bt, but cycles in the other direc-
-               tion.
-
-       -\b-s\bse\bel\ble\bec\bct\bt _\bn_\bu_\bm_\bb_\be_\br
-               Like  _\b-_\ba_\bc_\bt_\bi_\bv_\ba_\bt_\be,  but  runs the _\bNth element in the
-               list of hacks.  By knowing what is in the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs
-               list, and in what order, you can use this to acti-
-               vate the screensaver with  a  particular  graphics
-               demo.   (The first element in the list is numbered
-               1, not 0.)
-
-       -\b-e\bex\bxi\bit\bt   Causes the xscreensaver  process  to  exit  grace-
-               fully.   This  is  roughly the same as killing the
-               process with k\bki\bil\bll\bl(1), but it is easier, since  you
-               don't need to first figure out the pid.

-               virtual root window manager, that can leave things
-               in an inconsistent state,  and  you  may  need  to
-               restart  your window manager to repair the damage.
-
-       -\b-l\blo\boc\bck\bk   Tells the running xscreensaver process to lock the

-       The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br_\b-_\bd_\be_\bm_\bo program is a graphical front-end for
-       setting the parameters used  by  the  background  x\bxs\bsc\bcr\bre\bee\ben\bn-\b-
-       s\bsa\bav\bve\ber\br(1) daemon.  It is essentially two things: a tool for
-       editing the _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file; and a tool  for  demoing
-       the  various  graphics  hacks that the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br daemon
-       will launch.
-
-       The main dialog box contains  a  scrolling  list,  a  text
-       field, and a number of buttons.
-
-       Double-clicking  on  one  of the programs in the list will
-       run it.  The screen will go black, and  the  program  will
-       run  in full-screen mode, just as it would if the _\bx_\bs_\bc_\br_\be_\be_\bn_\b-
-       _\bs_\ba_\bv_\be_\br daemon had launched it.  Clicking  the  mouse  again
-       will  stop  the  demo  and un-blank the screen, making the
-       dialog box visible again.
-
-       Single-clicking in the list will place the indicated  pro-
-       gram  and  its  args in the text field to be edited.  Edit
-       the arguments and hit return to run the program  with  the
-       parameters  you  have specified.  This will also save your
-       changes to your _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file: so any  changes  you
-       make in this way are persistent.
-
-       If  one of the lines in the scrolling list begins with the
-       character "-", then that means that the  program  is  dis-
-       abled:  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  will not select it to be run (though
-       you can still try it out by clicking on it.)  Rather  than
-       just  deleting  the  programs  you  don't want to run, you
-       might want to disable them in this way  instead,  so  that
-       you can more easily change your mind later.
-
-       If  the line begins with the name of a visual, followed by
-       a colon, then that program will only be run on  that  kind
-       of visual.  For example, you can specify that a particular
-       program should only be run  if  color  is  available,  and
-       another should only be run in monochrome.  See the discus-
-       sion of the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs parameter in the  _\bC_\bo_\bn_\bf_\bi_\bg_\bu_\br_\ba_\bt_\bi_\bo_\bn  sec-
-       tion of the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) manual.
-
-       The buttons are:
-
-       R\bRu\bun\bn N\bNe\bex\bxt\bt
-               Clicking  this button will run the next program in
-               the list after  the  currently-selected  one,  and

-               have the option to interactively  change  most  of
-               the  screensaver's operational parameters, such as
-               its timeouts,  and  whether  it  should  lock  the
-               screen.   When  you click OK, your chosen settings
-               will take effect immediately,  and  will  also  be
-               saved  to  the  _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  file in your home

-               as before.
-
-       The  Preferences  dialog box lets you change the following
-       settings.

-       (There are more settings available, but these are the most
-       commonly used ones; see the manual for x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) for
-       other  parameters  that  can  be  set   by   editing   the

-               After the screensaver has been  running  for  this
-               long,  the currently running graphics demo will be
-               killed, and a new one started.  If this is 0, then
-               the  graphics demo will never be changed: only one
-               demo will run until the screensaver is deactivated
-               by user activity.

-               Whether  to  install  a private colormap while the
-               screensaver is active, so that the graphics  hacks
-               can  get  as  many colors as possible.  (This only
-               applies when the screen's default visual is  being
-               used, since non-default visuals get their own col-
-               ormaps automatically.)  This can also be  overrid-
-               den on a per-demo basis.

-               If  selected, then when the screensaver activates,
-               the current contents of the screen  will  fade  to
-               black  instead  of  simply winking out.  This only
-               works on displays with  writable  colormaps,  that
-               is,  if  the  screen's default visual is a Pseudo-
-               Color visual.  A  fade  will  also  be  done  when
-               switching  graphics  hacks (when the _\bC_\by_\bc_\bl_\be _\bT_\bi_\bm_\be_\bo_\bu_\bt

-               The complement to _\bF_\ba_\bd_\be _\bC_\bo_\bl_\bo_\br_\bm_\ba_\bp: if selected, then
-               when  the  screensaver  deactivates,  the original
-               contents of the screen will  fade  in  from  black
-               instead of appearing immediately.  This only works
-               on displays with writable colormaps, and when _\bF_\ba_\bd_\be
-               _\bC_\bo_\bl_\bo_\br_\bm_\ba_\bp is also selected.

-               When  fading  or  unfading are selected, this con-

-
-       F\bFa\bad\bde\be T\bTi\bic\bck\bks\bs
-               This controls how many times a second the colormap
-               will  be changed to effect a fade.  Higher numbers
-               yield smoother fades, but may make the fades  take
-               longer  than  the  specified number of seconds, if
-               your server isn't fast enough to keep up.

-               Whether the screen saver should  lock  the  screen
-               when it activates.
-
-       L\bLo\boc\bck\bk T\bTi\bim\bme\beo\bou\but\bt
-               If _\bR_\be_\bq_\bu_\bi_\br_\be _\bP_\ba_\bs_\bs_\bw_\bo_\br_\bd is selected, this controls the
-               length of the ``grace period''  between  when  the
-               screensaver activates, and when the screen becomes
-               locked.  For example,  if  this  is  0:05:00,  and
-               _\bS_\ba_\bv_\be_\br  _\bT_\bi_\bm_\be_\bo_\bu_\bt  is 0:10:00, then after 10 minutes,
-               the screen would blank.  If there was user  activ-
-               ity  at  12 minutes, no password would be required
-               to un-blank the screen.  But, if  there  was  user
-               activity  at  15  minutes  or later (that is, _\bL_\bo_\bc_\bk
-               _\bT_\bi_\bm_\be_\bo_\bu_\bt minutes after activation) then a  password
-               would be required.  The default is 0, meaning that
-               if locking is enabled, then  a  password  will  be
-               required as soon as the screen blanks.
-
-       P\bPa\bas\bss\bsw\bwo\bor\brd\bd T\bTi\bim\bme\beo\bou\but\bt
-               When  the screensaver is prompting for a password,
-               the prompt dialog box will stay on the screen  for
-               this  long  before  giving  up,  and  reverting to
-               screen-saving mode.

-       The _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br program  waits  until  the  keyboard  and
-       mouse  have been idle for a period, and then runs a graph-
-       ics demo chosen at random.  It turns off as soon as  there
-       is any mouse or keyboard activity.
-
-       This  program  can  lock your terminal in order to prevent
-       others from using it, though its default mode of operation
-       is  merely  to display pretty pictures on your screen when
-       it is not in use.
-
-       The benefit that this program has over the combination  of
-       the  x\bxl\blo\boc\bck\bk(1)  and  x\bxa\bau\but\bto\bol\blo\boc\bck\bk(1) programs is the ease with
-       which new graphics hacks can be installed.  You don't need
-       to  recompile  (or  even re-run) this program to add a new
-       display mode.

-       For the impatient, try this:

-            xscreensaver &
-            xscreensaver-demo
-
-       The x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1) program should pop  up  a  dialog
-       box  that  lets  you experiment with the xscreensaver set-
-       tings and graphics modes.
-
-       N\bNo\bot\bte\be:\b: unlike x\bxl\blo\boc\bck\bk(1), xscreensaver  has  a  client-server
-       model:  the  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br program is a daemon that runs in
-       the  background;  it  is  controlled  by  the   foreground
-       x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-d\bde\bem\bmo\bo(1) and x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd(1) programs.

-       in the X resource database.   If  the  _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  file
-       exists,   it   overrides  any  settings  in  the  resource

-
-       The syntax of the _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file is similar to that of
-       the  _\b._\bX_\bd_\be_\bf_\ba_\bu_\bl_\bt_\bs  file;  for  example,  to  set the _\bt_\bi_\bm_\be_\bo_\bu_\bt
-       paramter in the _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file, you  would  write  the
-       following:
-
-            timeout: 5
-
-       whereas, in the _\b._\bX_\bd_\be_\bf_\ba_\bu_\bl_\bt_\bs file, you would write
-
-            xscreensaver.timeout: 5
-
-       If  you  change  a setting in the _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file while
-       xscreensaver is already running, it will notice this,  and
-       reload the file.  (The file will be reloaded the next time
-       the screen saver needs to take some action, such as blank-
-       ing  or  unblanking  the screen, or picking a new graphics
-       mode.)
-
-       If you change a setting in your X resource database, or if
-       you  want  xscreensaver to notice your changes immediately
-       instead of the next time it wakes up, then you  will  need
-       to  tell the running xscreensaver process to re-initialize
-       itself, like so:
-
-            xscreensaver-command -restart
-
-       Note that if you changed the _\b._\bX_\bd_\be_\bf_\ba_\bu_\bl_\bt_\bs  file,  you  might
-       also need to run x\bxr\brd\bdb\bb(1):
-
-            xrdb < ~/.Xdefaults
-
-       If  you  want  to  set the system-wide defaults, then make
-       your edits to the xscreensaver  app-defaults  file,  which
-       should  have  been  installed when xscreensaver itself was
-       installed.  The app-defaults file will  usually  be  named
-       /usr/lib/X11/app-defaults/XScreenSaver, but different sys-
-       tems might keep it in  a  different  place  (for  example,
-       /usr/openwin/lib/app-defaults/XScreenSaver on Solaris.)
-
-       When  settings  are  changed in the Preferences dialog box
-       (see above) the current settings will be  written  to  the
-       _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  file.   (The  _\b._\bX_\bd_\be_\bf_\ba_\bu_\bl_\bt_\bs  file and the app-
-       defaults  file  will  never  be  written  by  xscreensaver
-       itself.)

-       t\bti\bim\bme\beo\bou\but\bt (class T\bTi\bim\bme\be)
-               The  screensaver  will activate (blank the screen)
-               after the keyboard and mouse have  been  idle  for
-               this many minutes.  Default 10 minutes.
-

-               sub-process  will  be killed (with S\bSI\bIG\bGT\bTE\bER\bRM\bM), and a
-               new one started.  If this is 0, then the  graphics
-               hack will never be changed: only one demo will run
-               until  the  screensaver  is  deactivated  by  user
-               activity.  Default 10 minutes.
-
-       l\blo\boc\bck\bk (class B\bBo\boo\bol\ble\bea\ban\bn)
-               Enable  locking:  before the screensaver will turn
-               off, it will require you to type the  password  of
-               the  logged-in  user  (really,  the person who ran
-               xscreensaver), or the root password.  (N\bNo\bot\bte\be:\b:  this
-               doesn't  work  if  the  screensaver is launched by
-               x\bxd\bdm\bm(1) because it can't know the  user-id  of  the
-               logged-in user.  See the ``_\bU_\bs_\bi_\bn_\bg _\bX_\bD_\bM_\b(_\b1_\b)'' section,
-               below.
-
-       l\blo\boc\bck\bkT\bTi\bim\bme\beo\bou\but\bt (class T\bTi\bim\bme\be)
-               If locking is enabled, this controls the length of
-               the  ``grace period'' between when the screensaver
-               activates, and when  the  screen  becomes  locked.
-               For  example,  if  this  is 5, and _\b-_\bt_\bi_\bm_\be_\bo_\bu_\bt is 10,
-               then after 10 minutes, the screen would blank.  If
-               there was user activity at 12 minutes, no password
-               would be required to un-blank the screen.  But, if
-               there  was  user  activity  at 15 minutes or later
-               (that is, _\b-_\bl_\bo_\bc_\bk_\b-_\bt_\bi_\bm_\be_\bo_\bu_\bt minutes after  activation)
-               then a password would be required.  The default is
-               0, meaning that if  locking  is  enabled,  then  a
-               password  will  be  required as soon as the screen
-               blanks.
-
-       p\bpa\bas\bss\bsw\bwd\bdT\bTi\bim\bme\beo\bou\but\bt (class T\bTi\bim\bme\be)
-               If the screen is locked, then  this  is  how  many
-               seconds  the password dialog box should be left on
-               the screen before giving up (default 30  seconds.)
-               This  should  not  be  too  large: the X server is
-               grabbed for the duration that the password  dialog
-               box  is up (for security purposes) and leaving the
-               server grabbed for too long can cause problems.

-               Specify which X visual to use by  default.   (Note
-               carefully  that  this resource is called v\bvi\bis\bsu\bua\bal\blI\bID\bD,

-                       with the most colors might be a  TrueColor
-                       visual,  which  does  not support colormap
-                       animation.  Some programs have more inter-
-                       esting  behavior  when  run on PseudoColor
-                       visuals than on TrueColor.

-
-               g\bgr\bra\bay\by    Use  a  grayscale or staticgray visual, if

-                       you  can  have  finer control over exactly
-                       which visual gets used,  for  example,  to
-                       select  a  shallower one than would other-
-                       wise have been chosen.
-
-               Note that this option specifies only  the  _\bd_\be_\bf_\ba_\bu_\bl_\bt

-               only works on displays  with  writable  colormaps,
-               that is, if the screen's default visual is a Pseu-
-               doColor visual.  A fade will  also  be  done  when
-               switching  graphics  hacks  (when  the _\bc_\by_\bc_\bl_\be timer
-               expires.)  Default: true.

-               If the display has multiple screens, then  a  dif-

-                           xv -root -rmode 5 image.gif -quit  \n
-
-               Make  sure  your $\b$P\bPA\bAT\bTH\bH environment variable is set
-               up correctly _\bb_\be_\bf_\bo_\br_\be xscreensaver is  launched,  or
-               it  won't  be  able to find the programs listed in
-               the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs resource.
-
-               To use a program as a screensaver, two things  are
-               required:  that that program draw on the root win-
-               dow (or be able to be configured to  draw  on  the
-               root  window);  and  that  that program understand
-               ``virtual root'' windows, as used by virtual  win-
-               dow  managers  such as t\btv\bvt\btw\bwm\bm(1).  (Generally, this
-               is accomplished by just  including  the  _\b"_\bv_\br_\bo_\bo_\bt_\b._\bh_\b"
-               header file in the program's source.)
-
-               If  there  are  some programs that you want to run
-               only when using a color display, and  others  that
-               you  want to run only when using a monochrome dis-
-               play, you can specify that like this:
-
-                           mono:   mono-program  -root        \n\
-                           color:  color-program -root        \n\
-
-               More generally, you can specify the kind of visual
-               that  should  be  used for the window on which the
-               program will be drawing.  For example, if one pro-
-               gram  works best if it has a colormap, but another
-               works best if it has a 24-bit visual, both can  be
-               accommodated:
-
-                           PseudoColor: cmap-program  -root   \n\
-                           TrueColor:   24bit-program -root   \n\
-
-               In addition to the symbolic visual names described
-               above (in the discussion of the _\bv_\bi_\bs_\bu_\ba_\bl_\bI_\bD resource)
-               one other visual name is supported in the _\bp_\br_\bo_\bg_\br_\ba_\bm_\bs
-               list:
-
-                d\bde\bef\bfa\bau\bul\blt\bt-\b-n\bn

-                    use  of  the  default  colormap, instead of a
-                    private colormap.  (That is, it behaves as if
-                    the _\b-_\bn_\bo_\b-_\bi_\bn_\bs_\bt_\ba_\bl_\bl command-line option was spec-
-                    ified, but only for  this  particular  hack.)
-                    This  is  provided  because  some third-party
-                    programs  that  draw  on  the   root   window
-                    (notably:  x\bxv\bv(1), and x\bxe\bea\bar\brt\bth\bh(1)) make assump-
-                    tions about the visual and  colormap  of  the
-                    root  window:  assumptions which xscreensaver
-                    can violate.
-
-               If you specify a particular visual for a  program,
-               and that visual does not exist on the screen, then
-               that program will not  be  chosen  to  run.   This
-               means  that  on  displays with multiple screens of
-               different depths, you can arrange for  appropriate
-               hacks  to  be  run  on  each.  For example, if one
-               screen is color and the other is monochrome, hacks
-               that  look  good  in  mono  can be run on one, and
-               hacks that only look good in color will show up on
-               the other.

-               the  mouse  position  or  buttons  have   changed.

-               When  server  extensions are not in use, this con-
-               trols the delay between when windows  are  created
-               and  when  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  selects  events  on them.

-               _\bs_\ba_\bv_\be_\br will wait this many seconds before selecting

-               that  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  is  started  during your login
-               procedure, and the window state may  be  in  flux.
-               Default  0.  (This used to default to 30, but that
-               was back in the days when slow machines and X ter-

-               _\bs_\ba_\bv_\be_\br has been compiled on a system which supports
-               this mechanism (i.e., Linux systems.)
-
-               The benefit to doing this is that _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br can
-               note that the user is active even when the X  con-
-               sole  is not the active one: if the user is typing
-               in  another  virtual  console,  xscreensaver  will
-               notice  that and will fail to activate.  For exam-
-               ple, if you're playing Quake in VGA-mode, xscreen-
-               saver won't wake up in the middle of your game and
-               start competing for CPU.
-
-               The drawback to doing this  is  that  perhaps  you
-               _\br_\be_\ba_\bl_\bl_\by  _\bd_\bo want idleness on the X console to cause
-               the X display to lock, even if there  is  activity

-       When it is time to activate the screensaver, a full-screen
-       black  window  is  created  on each screen of the display.
-       Each window is created in such a way that, to  any  subse-
-       quently-created programs, it will appear to be a ``virtual
-       root'' window.  Because of this, any program  which  draws
-       on  the  root window (and which understands virtual roots)
-       can be used as a screensaver.
-
-       When the user becomes active again, the  screensaver  win-
-       dows are unmapped, and the running subprocesses are killed
-       by sending them S\bSI\bIG\bGT\bTE\bER\bRM\bM.  This is  also  how  the  subpro-
-       cesses  are  killed when the screensaver decides that it's
-       time to run a different demo: the old one is killed and  a
-       new one is launched.
-
-       Before  launching  a  subprocess,  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  stores an
-       appropriate value for $\b$D\bDI\bIS\bSP\bPL\bLA\bAY\bY in the environment that the
-       child  will  recieve.   (This  is  so  that  if  you start
-       _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br with a _\b-_\bd_\bi_\bs_\bp_\bl_\ba_\by argument, the programs  which
-       _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  launches  will draw on the same display; and
-       so that the child will end up drawing on  the  appropriate
-       screen of a multi-headed display.)
-
-       When  the  screensaver  turns  off,  or is killed, care is
-       taken to restore the ``real'' virtual root window if there
-       is  one.   Because  of  this, it is important that you not
-       kill the screensaver process with _\bk_\bi_\bl_\bl _\b-_\b9 if you are  run-
-       ning  a  virtual-root window manager.  If you kill it with
-       -9, you may need to restart your window manager to  repair
-       the  damage.   This isn't an issue if you aren't running a
-       virtual-root window manager.
-
-       For all the gory details, see the commentary at the top of
-       xscreensaver.c.
-
-       You can control a running screensaver process by using the
-       x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd(1) program (which see.)

-       Modern X servers contain support to power down the monitor
-       after  an  idle  period.  If the monitor has powered down,
-       then _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br will notice this, and will not waste CPU
-       by  drawing  graphics demos on a black screen.  An attempt
-       will also be made to explicitly power the monitor back  up
-       as soon as user activity is detected.
-
-       If  your  X server supports power management, then x\bxs\bse\bet\bt(1)
-       will accept a d\bdp\bpm\bms\bs option.  So, if you wanted _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br
-       to  activate  after 5 minutes, but you wanted your monitor
-       to power down after one hour (3600 seconds) you  would  do
-       this:
-
-            xset dpms 3600
-
-       See  the  man  page  for  the x\bxs\bse\bet\bt(1) program for details.
-       (Note that power management requires both software support
-       in  the  X  server,  and  hardware  support in the monitor
-       itself.)

-       You can run _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br from your x\bxd\bdm\bm(1) session, so that
-       the  screensaver will run even when nobody is logged in on
-       the console.
-
-       The trick to using xscreensaver with _\bx_\bd_\bm is this: keep  in
-       mind  the  two very different states in which xscreensaver
-       will be running:
-
-           1\b1:\b: N\bNo\bob\bbo\bod\bdy\by l\blo\bog\bgg\bge\bed\bd i\bin\bn.\b.
-
-              If you're thinking of running xscreensaver from XDM
-              at  all, then it's probably because you want graph-
-              ics demos to be running on the console when  nobody
-              is  logged  in  there.   In this case, xscreensaver
-              will function only as a screen saver, not a  screen
-              locker:  it  doesn't make sense for xscreensaver to
-              lock the screen, since nobody  is  logged  in  yet!
-              The  only  thing  on  the  screen  is the XDM login
-              prompt.
-
-           2\b2:\b: S\bSo\bom\bme\beb\bbo\bod\bdy\by l\blo\bog\bgg\bge\bed\bd i\bin\bn.\b.
-
-              Once someone has logged in through  the  XDM  login
-              window, the situation is very different.  For exam-
-              ple: now it makes sense to  lock  the  screen  (and
-              prompt  for the logged in user's password); and now
-              xscreensaver should consult that user's _\b~_\b/_\b._\bx_\bs_\bc_\br_\be_\be_\bn_\b-
-              _\bs_\ba_\bv_\be_\br file; and so on.
-
-       The  difference  between  these two states comes down to a
-       question of, which user is the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  process  run-
-       ning  as?  For the first state, it doesn't matter.  If you

-
-
-       start _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br in the usual XDM way, then xscreensaver
-       will  probably  end  up running as root, which is fine for
-       the first case (the ``nobody logged in'' case.)
-
-       However, once someone is logged in, running as root is  no
-       longer  fine:  because  xscreensaver  will  be  consulting
-       root's _\b._\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br file instead of that of the logged in
-       user,  and  won't  be  prompting  for the logged in user's
-       password, and so on.  (This is  not  a  security  problem,
-       it's just not what you want.)
-
-       So,  once  someone has logged in, you want xscreensaver to
-       be running as that user.  The way to accomplish this is to
-       kill  the old xscreensaver process and start a new one (as
-       the new user.)
-
-       The simplest way to accomplish all of this is as follows:

-
-                   xscreensaver-command -exit
-                   xscreensaver &
-
-              This will run xscreensaver as root,  over  the  XDM
-              login  window.   Moving  the  mouse  will cause the
-              screen to un-blank, and  allow  the  user  to  type
-              their password at XDM to log in.

-              add those same lines:
-
-                   xscreensaver-command -exit
-                   xscreensaver &
-
-              When someone logs in, this will kill off the exist-
-              ing  (root)  xscreensaver  process, and start a new
-              one, running as the user who has  just  logged  in.
-              If  the user's .xscreensaver file requests locking,
-              they'll get it.   They  will  also  get  their  own
-              choice  of timeouts, and graphics demos, and so on.
-
-              Alternately, each user could just put  those  lines
-              in their personal _\b~_\b/_\b._\bx_\bs_\be_\bs_\bs_\bi_\bo_\bn files.
-

-       file,  you  may  need to configure it to do so: the tradi-
-       tional way to do this is to make that file  the  value  of
-       the      _\bD_\bi_\bs_\bp_\bl_\ba_\by_\bM_\ba_\bn_\ba_\bg_\be_\br_\b*_\bs_\be_\bt_\bu_\bp      resource     in     the
-       _\b/_\bu_\bs_\br_\b/_\bl_\bi_\bb_\b/_\bX_\b1_\b1_\b/_\bx_\bd_\bm_\b/_\bx_\bd_\bm_\b-_\bc_\bo_\bn_\bf_\bi_\bg file.  See the  man  page  for
-       x\bxd\bdm\bm(1) for more details.)
-
-       It  is  safe to run _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br as root (as _\bx_\bd_\bm is likely
-       to do.)  If run as root, _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br changes  its  effec-
-       tive  user and group ids to something safe (like _\b"_\bn_\bo_\bb_\bo_\bd_\by_\b")
-       before connecting to the X server or launching user-speci-
-       fied programs.
-
-       An  unfortunate  side  effect of this (important) security
-       precaution is  that  it  may  conflict  with  cookie-based
-       authentication.
-
-       If  you  get  "connection  refused"  errors  when  running
-       _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br from _\bx_\bd_\bm, then this probably means  that  you
-       have  x\bxa\bau\but\bth\bh(1) or some other security mechanism turned on.
-       One way  around  this  is  to  add  "\b"x\bxh\bho\bos\bst\bt +\b+l\blo\boc\bca\bal\blh\bho\bos\bst\bt"\b"  to
-       _\bX_\bs_\be_\bt_\bu_\bp, just before _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br is launched.
-
-       Note  that this will give access to the X server to anyone
-       capable of logging in to the local  machine,  so  in  some
-       environments,  this  might not be appropriate.  If turning
-       off file-system-based access control  is  not  acceptable,
-       then  running  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br from the _\bX_\bs_\be_\bt_\bu_\bp file might not
-       be possible, and xscreensaver will only work when  running
-       as a normal, unprivileged user.
-
-       For  more  information  on  the  X server's access control
-       mechanisms, see the  man  pages  for  X\bX(1),  X\bXs\bse\bec\bcu\bur\bri\bit\bty\by(1),

-       The  easiest  way to use _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br on a system with CDE
-       is to simply switch off the built-in CDE screensaver,  and
-       use  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  instead;  and second, to tell the front
-       panel to run x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd(1) with the _\b-_\bl_\bo_\bc_\bk option
-       when the _\bL_\bo_\bc_\bk icon is clicked.

-              Do  this  by  turning off ``_\bS_\bc_\br_\be_\be_\bn _\bS_\ba_\bv_\be_\br _\ba_\bn_\bd _\bS_\bc_\br_\be_\be_\bn
-              _\bL_\bo_\bc_\bk'' in the Screen section of the Style  Manager.

-               have  logged  in,  or  you will be confused by the

-               (as _\bx_\bd_\bm is likely to do), xscreensaver  will  dis-
-               avow  its  privileges, and switch itself to a safe
-               user id (such as _\bn_\bo_\bb_\bo_\bd_\by.)
-
-               An implication of this is that if you  log  in  as
-               _\br_\bo_\bo_\bt  on  the console, xscreensaver will refuse to
-               lock the screen (because it can't tell the differ-
-               ence  between _\br_\bo_\bo_\bt being logged in on the console,
-               and a normal user being logged in on  the  console
-               but  xscreensaver  having  been  launched  by  the
-               x\bxd\bdm\bm(1) _\bX_\bs_\be_\bt_\bu_\bp file.)
-
-               The solution to this is simple: you  shouldn't  be
-               logging  in  on  the  console as _\br_\bo_\bo_\bt in the first
-               place!  (What, are you crazy or something?)
-
-               Proper Unix hygiene dictates that you  should  log
-               in  as  yourself,  and s\bsu\bu(1) to _\br_\bo_\bo_\bt as necessary.
-               People who spend their day logged in as  _\br_\bo_\bo_\bt  are
-               just begging for disaster.

-               For  xscreensaver to work when launched by x\bxd\bdm\bm(1),
-               programs running on  the  local  machine  as  user
-               _\b"_\bn_\bo_\bb_\bo_\bd_\by_\b"  must be able to connect to the X server.
-               This means that if you want to run xscreensaver on
-               the  console  while  nobody  is logged in, you may
-               need to disable cookie-based access  control  (and
-               allow  all  users  who  can  log  in  to the local
-               machine to connect to the display.)
-
-               You should be sure  that  this  is  an  acceptable
-               thing  to  do in your environment before doing it.

-               If  anyone  has  suggestions  on  how xscreensaver
-               could be made to work with  x\bxd\bdm\bm(1)  without  first
-               turning   off  _\b._\bX_\ba_\bu_\bt_\bh_\bo_\br_\bi_\bt_\by-based  access  control,

-               to make this a safe thing to do.
-
-               It  also  may  mean  that  your system uses shadow
-               passwords  instead  of  the  standard  g\bge\bet\btp\bpw\bwe\ben\bnt\bt(3)
-               interface;  in  that  case, you may need to change
-               some options with _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\be and recompile.
-
-               If you change your password after xscreensaver has
-               been  launched,  it  will  continue using your old
-               password to unlock the screen  until  xscreensaver
-               is restarted.  So, after you change your password,
-               you'll have to do
-
-                    xscreensaver-command -restart
-
-               to make _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br notice.

-               If your system uses PAM (Pluggable  Authentication
-               Modules),  then  in  order for xscreensaver to use
-               PAM properly, PAM must be told about xscreensaver.
-               The   xscreensaver   installation  process  should
-               update the PAM data (on  Linux,  by  creating  the
-               file   _\b/_\be_\bt_\bc_\b/_\bp_\ba_\bm_\b._\bd_\b/_\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  for  you,  and  on
-               Solaris, by telling you what lines to add  to  the
-               _\b/_\be_\bt_\bc_\b/_\bp_\ba_\bm_\b._\bc_\bo_\bn_\bf file.)
-
-               If  the  PAM configuration files do not know about
-               xscreensaver, then you _\bm_\bi_\bg_\bh_\bt  be  in  a  situation
-               where  xscreensaver will refuse to ever unlock the
-               screen.
-
-               This is a design flaw in PAM (there is no way  for
-               a  client  to  tell  the  difference  between  PAM
-               responding ``I have never heard of your  module,''
-               and responding, ``you typed the wrong password.'')
-               As far as I can tell, there is no way for xscreen-
-               saver to automatically work around this, or detect
-               the problem in advance, so if you have  PAM,  make
-               sure it is configured correctly!

-               The  i\bin\bns\bst\bta\bal\bll\blC\bCo\bol\blo\bor\brm\bma\bap\bp option doesn't work very well
-               with the t\btw\bwm\bm(1) window  manager  and  its  descen-
-               dants.
-
-               There  is a race condition between the screensaver
-               and this window manager, which can result  in  the
-               screensaver's colormap not getting installed prop-

-
-
-               this problem.  The race condition exists because X
-               (really, ICCCM) does not  provide  a  way  for  an
-               OverrideRedirect  window to have its own colormap,
-               short of grabbing the server (which is  neither  a
-               good  idea,  nor  really possible with the current
-               design.)   What  happens  is  that,  as  soon   as
-               xscreensaver  installs  its colormap, t\btw\bwm\bm responds
-               to  the  resultant  C\bCo\bol\blo\bor\brm\bma\bap\bpN\bNo\bot\bti\bif\bfy\by  event  by  re-
-               instaling  the  default colormap.  Apparently, t\btw\bwm\bm
-               doesn't _\ba_\bl_\bw_\ba_\by_\bs do this; it seems to  do  it  regu-
-               larly  if the screensaver is activated from a menu
-               item, but seems to not do it  if  the  screensaver
-               comes on of its own volition, or is activated from
-               another console.

-                   response  to  user  events.   That  is,  it is

-                   events.  If you install colormaps in  response

-                   to _\bu_\bs_\be_\br actions, then you create the situation

-               Some  programs  don't  operate properly on visuals
-               other than the  default  one,  or  with  colormaps
-               other than the default one.  See the discussion of

-               section.  When programs only work with the default
-               colormap, you need to use a syntax like this:
-
-                       default-n: xv -root image-1.gif -quit  \n\
-                       default-n: xearth -nostars -wait 0     \n\
-
-               It would also work to turn off the i\bin\bns\bst\bta\bal\bll\blC\bCo\bol\blo\bor\brm\bma\bap\bp
-               option altogether, but that would deny extra  col-
-               ors  to  those programs that _\bc_\ba_\bn take advantage of

-               Although this program ``nices''  the  subprocesses
-               that it starts, graphics-intensive subprograms can
-               still overload the machine by causing the X server
-               process  itself (which is not ``niced'') to suck a
-               lot of cycles.  Care should be taken to slow  down
-               programs  intended  for  use  as  screensavers  by
-               inserting strategic calls to s\bsl\ble\bee\bep\bp(3) or u\bus\bsl\ble\bee\bep\bp(3)

-               Note that the OpenGL-based graphics demos are real
-               pigs on machines that don't have texture hardware.
-
-               Also, an active  screensaver  will  cause  your  X
-               server  to  be pretty much permanently swapped in;
-               but the same is true of  any  program  that  draws
-               periodically, like x\bxc\bcl\blo\boc\bck\bk(1) or x\bxl\blo\boa\bad\bd(1).

-               If  the  subprocess is drawing too quickly and the
-               connection to the X server is a slow one (such  as
-               an  X terminal running over a phone line) then the
-               screensaver might not turn off right away when the
-               user  becomes  active  again  (the i\bic\bco\bo(1) demo has
-               this problem if being  run  in  full-speed  mode).
-               This  can  be  alleviated  by  inserting strategic
-               calls to X\bXS\bSy\byn\bnc\bc(3) in code intended for  use  as  a
-               screensaver.   This  prevents  too  much  graphics
-               activity from being buffered up.

-               The  XFree86  X   server   traps   certain   magic
-               keystrokes  before  client programs ever see them.
-               Two that are of note are Ctrl+Alt+Backspace, which
-               causes  the  X  server  to  exit; and Ctrl+Alt+F_\bn,
-               which switches virtual  consoles.   The  X  server
-               will  respond to these keystrokes even if xscreen-
-               saver has the screen locked.   Depending  on  your
-               setup, you might consider this a problem.
-
-               Unfortunately,  there  is  no way for xscreensaver
-               itself to override  the  interpretation  of  these
-               keys.   If  you want to disable Ctrl+Alt+Backspace
-               globally, you need to set the _\bD_\bo_\bn_\bt_\bZ_\ba_\bp flag in your
-               _\b/_\be_\bt_\bc_\b/_\bX_\b1_\b1_\b/_\bX_\bF_\b8_\b6_\bC_\bo_\bn_\bf_\bi_\bg  file.   See the X\bXF\bF8\b86\b6C\bCo\bon\bnf\bfi\big\bg(5)
-               manual for details.
-
-               There is no way (as far as I can tell) to  disable
-               the VT-switching keystrokes.
-
-               Some  Linux  systems  come  with  a  VT_LOCKSWITCH
-               ioctl, that one could theoretically use to prevent
-               VT-switching  while  the  screen  is  locked;  but
-               unfortunately, this ioctl  can  only  be  used  by
-               root,  which  means that xscreensaver can't use it
-               (since  xscreensaver   disavows   its   privileges
-               shortly after startup, for security reasons.)
-
-               Any  suggestions for other solutions to this prob-
-               lem are welcome.

-               Apparently there are some problems with XView pro-
-               grams  getting  confused  and  thinking  that  the
-               screensaver window is the real  root  window  even
-               when the screensaver is not active: ClientMessages
-               intended for the window manager are  sent  to  the
-               screensaver  window instead.  This could be solved
-               by making xscreensaver  forward  all  unrecognised
-               ClientMessages  to the real root window, but there
-               may be other problems as well.  If anyone has  any
-               insight  on  the cause of this problem, please let
-               me know.  (XView is an X11 toolkit that implements

-               junction with the f\bfa\bad\bde\be option,  you'll  notice  an
-               unattractive  flicker just before the fade begins.
-               This is because the server  maps  a  black  window
-               just  before  it tells the _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br process to
-               activate.  The  _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br  process  immediately
-               unmaps that window, but this results in a flicker.

-               the GL hacks from this:
-
-                           gears -root                        \n\
-

-
-                           MESA_GLX_FX=fullscreen  gears      \n\
-
-               That  is,  make  sure  that $\b$M\bME\bES\bSA\bA_\b_G\bGL\bLX\bX_\b_F\bFX\bX is set to
-               _\bf_\bu_\bl_\bl_\bs_\bc_\br_\be_\be_\bn, and don't tell the program to draw  on
-               the  root  window.  This may seem strange, but the
-               setup used by Mesa and these  kinds  of  cards  _\bi_\bs
-               strange!
-
-               For those who don't know, these cards work by sit-
-               ting between your normal video card and the  moni-
-               tor,  and seizing control of the monitor when it's
-               time to do 3D.  But this means that accelerated 3D
-               only  happens in full-screen mode (you can't do it
-               in a window, and you can't see the  output  of  3D
-               and  2D programs simultaniously), and that 3D will
-               probably drive your monitor at a lower resolution,
-               as well.  It's bizarre.
-
-               If  you  find  that GL programs only work properly
-               when run as root, and not as  normal  users,  then
-               the  problem  is  that  your _\b/_\bd_\be_\bv_\b/_\b3_\bd_\bf_\bx file is not
-               configured properly.  Check the Linux 3Dfx FAQ.
-
-       K\bKe\bey\byb\bbo\boa\bar\brd\bd L\bLE\bED\bDs\bs
-               If _\bp_\br_\bo_\bc_\bI_\bn_\bt_\be_\br_\br_\bu_\bp_\bt_\bs is on (which is the  default  on
-               Linux  systems) and you're using some program that
-               toggles the state of your keyboard LEDs,  xscreen-
-               saver  won't  work right: turning those LEDs on or
-               off causes a keyboard  interrupt,  which  xscreen-
-               saver  will  interpret  as  user  activity.  So if
-               you're using such a program,  set  the  _\bp_\br_\bo_\bc_\bI_\bn_\bt_\be_\br_\b-
-               _\br_\bu_\bp_\bt_\bs resource to False.

-               extensions  (X\bXI\bID\bDL\bLE\bE,  S\bSG\bGI\bI  S\bSC\bCR\bRE\bEE\bEN\bN_\b_S\bSA\bAV\bVE\bER\bR,  or   M\bMI\bIT\bT-\b-
-               S\bSC\bCR\bRE\bEE\bEN\bN-\b-S\bSA\bAV\bVE\bER\bR), then it is possible, in rare situa-
-               tions, for _\bx_\bs_\bc_\br_\be_\be_\bn_\bs_\ba_\bv_\be_\br to  interfere  with  event
-               propagation  and  make  another X program malfunc-
-               tion.  For this to occur, that  other  application
-               would  need  to  _\bn_\bo_\bt select K\bKe\bey\byP\bPr\bre\bes\bss\bs events on its
-               non-leaf windows within the first  30  seconds  of
-               their  existence,  but then select for them later.
-               In this case, that client _\bm_\bi_\bg_\bh_\bt  fail  to  receive
-               those  events.  This isn't very likely, since pro-
-               grams generally select a constant  set  of  events
-               immediately  after creating their windows and then
-               don't change them, but this  is  the  reason  that

-.SH DESCRIPTION
-The \fIattraction\fP program has several visually different modes of 
-operation, all of which are based on the interactions of a set of control
-points which attract each other up to a certain distance, and then begin
-to repel each other.  The attraction/repulsion is proportional to the 
-distance between any two particles.
-.SH OPTIONS
-.I attraction
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-mono 
-If on a color display, pretend we're on a monochrome display.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-points integer
-How many control points should be used, or 0 to select the number randomly.
-Default 0.  Between 3 and 15 works best.
-.TP 8
-.B \-threshold integer
-The distance (in pixels) from each particle at which the attractive force
-becomes repulsive.  Default 100.
-.TP 8
-.B \-mode "balls | lines | polygons | tails | splines | filled-splines"
-In \fIballs\fP mode (the default) the control points are drawn as filled
-circles.  The larger the circle, the more massive the particle.
-
-In \fIlines\fP mode, the control points are connected by straight lines;
-the effect is something like \fIqix\fP.
-
-In \fIpolygons\fP mode, the control points are connected by straight
-lines, and filled in.  This is most interesting in color.
-
-In \fIsplines\fP mode, a closed spline is interpolated from the control 
-points.
-
-In \fIfilled-splines\fP mode, the splines are filled in instead of being
-outlines.  This is most interesting in color.
-
-In \fItails\fP mode, the path which each particle follows is indicated
-by a worm-like trail, whose length is controlled by the \fIsegments\fP
-parameter.
-.TP 8
-.B \-size integer
-The size of the balls in pixels, or 0, meaning to select the sizes 
-randomly (the default.)  If this is specified, then all balls will be 
-the same size.  This option has an effect in all modes, since the ``size''
-of the balls controls their mass.
-.TP 8
-.B \-segments integer
-If in \fIlines\fP or \fIpolygons\fP mode, how many sets of line segments
-or polygons should be drawn. Default 100.  This has no effect in \fIballs\fP
-mode.  If \fIsegments\fP is 0, then no segments will ever be erased (this
-is only useful in color.)
-.TP 8
-.B \-delay microseconds
-How much of a delay should be introduced between steps of the animation.
-Default 10000, or about 0.01 seconds.
-.TP 8
-.B \-color-shift int
-If on a color display, the color of the line segments or polygons will 
-cycle through the color map.  This specifies how many lines will be drawn
-before a new color is chosen.  (When a small number of colors are available,
-increasing this value will yield smoother transitions.)  Default 3.
-This has no effect in \fIballs\fP mode.
-.TP 8
-.B \-radius
-The size in pixels of the circle on which the points are initially positioned.
-The default is slightly smaller than the size of the window.
-.TP 8
-.B \-glow
-This is consulted only in \fIballs\fP mode.  If this is specified, then 
-the saturation of the colors of the points will vary according to their
-current acceleration.  This has the effect that the balls flare brighter
-when they are reacting to each other most strongly.
-
-In \fIglow\fP mode, all of the balls will be drawn the same (random)
-color, modulo the saturation shifts.  In non-glow mode, the balls will
-each be drawn in a random color that doesn't change.
-.TP 8
-.B \-noglow
-Don't do ``glowing.''  This is the default.
-.TP 8
-.B \-vx pixels
-.TP 8
-.B \-vy pixels
-Initial velocity of the balls.  This has no effect in \fB\-orbit\fP mode.
-.TP 8
-.B \-orbit
-Make the initial force on each ball be tangential to the circle on which
-they are initially placed, with the right velocity to hold them in orbit
-about each other.  After a while, roundoff errors will cause the orbit
-to decay.
-.TP 8
-.B \-vmult float
-In orbit mode, the initial velocity of the balls is multiplied by this;
-a number less than 1 will make the balls pull closer together, and a larger
-number will make them move apart.  The default is 0.9, meaning a slight
-inward pull.
-.TP 8
-.B \-viscosity float
-This sets the viscosity of the hypothetical fluid through which the control
-points move; the default is 1, meaning no resistance.  Values higher than 1
-aren't interesting; lower values cause less motion.
-
-One interesting thing to try is
-.EX
-attraction -viscosity 0.8 -points 75 \\
-  -mouse -geometry =500x500
-.EE
-Give it a few seconds to settle down into a stable clump, and then move
-the mouse through it to make "waves".
-.TP 8
-.B \-mouse
-This will cause the mouse to be considered a control point; it will not be
-drawn, but it will influence the other points, so you can wave the mouse
-and influence the images being created.
-.TP 8
-.B \-no-mouse
-Turns off \fB\-mouse\fP.
-.TP 8
-.B \-mouse-size integer
-In \fB\-mouse\fP mode, this sets the mass of the mouse (analagously to the
-\fB\-size\fP parameter.)
-.SH ENVIRONMENT

-.TH XScreenSaver 1 "24-Nov-97" "X Version 11"
-.SH NAME
-blitspin - rotate a bitmap in an interesting way
-.SH SYNOPSIS
-.B blitspin
-[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-bitmap \fIfilename\fP] [\-delay \fIusecs\fP] [\-delay2 \fIusecs\fP]
-.SH DESCRIPTION
-The \fIblitspin\fP program repeatedly rotates a bitmap by 90 degrees by
-using logical operations: the bitmap is divided into quadrants, and the
-quadrants are shifted clockwise.  Then the same thing is done again with
-progressively smaller quadrants, except that all sub-quadrants of a 
-given size are rotated in parallel.  So this takes \fBO(16*log2(N))\fP 
-blits of size NxN, with the limitation that the image must be square,
-and the size must be a power of 2.
-.SH OPTIONS
-.I blitspin
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-mono 
-If on a color display, pretend we're on a monochrome display.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-bitmap \fIfilename\fP
-The file name of a bitmap to rotate.  It need not be square: it 
-will be padded with the background color.  If unspecified or the
-string \fI(default)\fP, a builtin bitmap is used.
-
-If support for the \fIXPM\fP library was enabled at compile-time, 
-the specified file may be in \fIXPM\fP format as well as \fIXBM\fP, and 
-thus may be a color image.
-
-The \fB*bitmapFilePath\fP resource will be searched if the bitmap
-name is not a fully-qualified pathname.
-.TP 8
-.B \-grab\-screen
-If this option is specified, then the image which is spun will be grabbed
-from the portion of the screen underlying the blitspin window.  (Or, it
-may come from an external video source: see below.)
-.PP
-.TP 8
-.B \-delay \fImicroseconds\fP
-How long to delay between steps of the rotation process, in microseconds.
-Default is 500000, one-half second.
-.PP
-.TP 8
-.B \-delay2 \fImicroseconds\fP
-How long to delay between each 90-degree rotation, in microseconds.
-Default is 500000, one-half second.
-.B DISPLAY
-to get the default host and display number.
-.SH RESOURCES
-On some systems (currently, only SGIs), this program can, instead of grabbing
-a desktop image, grab a frame of video from an external camera and manipulate
-that instead.  The following resources control that.
-.PP
-.TP 8
-.B grabVideoProbability \fR(Float)\fP
-What portion of the time to grab video rather than a screen image, 
-between 0.0 and 1.0.  Defaults to 0.5, or half the time.
-.TP 8
-.B videoDevice \fR(Integer)\fP
-The number of the default video input device to check first.  If unspecified, 
-the default camera (from videopanel(1)) will be checked first.  After that, all
-other available video input devices will be checked in order.  
-
-The first one which produces a non-black image will be used.  If all images
-are black, the others will be re-checked a few times before giving up and
-falling back to simply grabbing a desktop image (but note that this takes a
-few seconds, so if you don't actually have any video sources hooked up, you
-should consider turning off video grabbing by setting
-\fBgrabVideoProbability\fP to 0.0.)
-.TP 8
-.B videoGain \fR(Float)\fP
-The amount by which to brighten the grabbed image.  This defaults to 2.2.

-stored in the RESOURCE_MANAGER property.

-.SH X RESOURCES
-Notable X resources supported include the following, which control which
-hacks are displayed and which aren't.
-.BR doWindows ,
-.BR doNT ,
-.BR doAmiga ,
-.BR doMac ,
-.BR doMacsBug ,
-.BR doSCO ,
-.BR doAtari ,
-and
-.BR doSparcLinux .
-Each of these is a Boolean resource, they all default to true, except for
-doSparcLinux and doAtari, which are turned off by default, because they're
-really not all that interesting looking unless you're a fan of those systems.
-There aren't command-line options for these, so to change them, you'll need
-to add entries to your .Xdefaults file, or use the -xrm option.
-For example, to tell bsod not to show the NT crash:
-.EX
-bsod -xrm '*doNT: false'
-.EE
-.SH BUGS
-Unlike the systems that the images are borrowed from,
-.I bsod
-does not require a reboot after running.
-.PP
-.I bsod
-should also emulate more systems, but systems with interesting crash
-graphics are not as common as one might hope.
-
-One I'd really like to see is a Unix system getting a kernel panic, 
-rebooting, and running
-.BR fsck (8).

-.SH NAME
-bubbles - frying pan / soft drink simulation
-.SH SYNOPSIS
-.B bubbles
-[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-simple] [\-broken] [\-3D] [\-file filename] [\-directory directoryname]
-.SH DESCRIPTION
-\fIBubbles\fP sprays lots of little random bubbles all over the window which
-then grow until they reach their maximum size and go pop.  The inspiration
-for this was watching little globules of oil on the bottom of a frying pan
-and it also looks a little like bubbles in fizzy soft drink.  The default
-mode uses fancy ray-traced bubbles but there is also a mode which just draws 
-circles in case the default mode is too taxing on your hardware.
-.SH OPTIONS
-Depending on how your
-.I bubbles
-was compiled, it accepts the following options:
-.TP 8
-.B \-foreground
-Colour of circles if \fI\-simple\fP mode is selected.
-.TP 8
-.B \-background
-Colour of window background.
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-mono 
-If on a color display, pretend we're on a monochrome display.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-delay microseconds
-How much of a delay should be introduced between steps of the animation.
-Default 1, or about 1 microsecond.  Actually, this is the delay between each
-group of 15 new bubbles since such a delay between each step results in a
-very slow animation rate.
-.TP 8
-.B \-nodelay
-Same as \fI\-delay 0\fP.
-.TP 8
-.B \-simple
-Don't use the default fancy pixmap bubbles.  Just draw circles instead.
-This may give more bearable performance if your hardware wasn't made for
-this sort of thing.
-.TP 8
-.B \-broken
-Don't hide bubbles when they pop.  This was a bug during development
-but the results were actually quite attractive.  (This option is only
-available if you have the XPM library available and the imake generated
-Makefile has defined HAVE_XPM).
-.TP 8
-.B \-3D
-Normally, the simulation is done completely in two dimensions.  When a
-bubble swallows up another bubble, the areas of each are added to get
-the area of the resulting bubble.  This option changes the algorithm
-to instead add volume (imagining each to be a sphere in 3D space).  The
-whole thing looks more realistic but I find it attracts attention to
-the flickering of each bubble as they are move and are redrawn.  Your
-mileage may vary.
-.TP 8
-.B \-file filename
-Use the pixmap definitions in the given file, instead of the default (if
-one is compiled in).  This is ignored if \fI\-simple\fP is specified.  If
-the file is compressed (either with compress or gzip), it is decompressed
-before use.  (This option only works if you have XPM compiled into your
-binary and you have compiled with BUBBLES_IO set in bubbles.h.  This is
-\fBnot\fP the default).
-.TP 8
-.B \-directory directoryname
-Similar to \fI-file\fP except the file is taken randomly from the
-contents of the specified directory.  (Again, this option is only available
-if you have XPM and BUBBLES_IO was set when compiling.  See above).
-.TP 8
-.B \-quiet
-Don't print messages explaining why one or several command line options
-were ignored.  This is disabled by default.
-.SH NOTES
-If you find the pace of things too slow, remember that there is a delay
-even though you specify no \fI\-delay\fP option.  Try using \fI\-nodelay\fP
-although beware of the effects of irritation of other users if you're on a 
-shared system as you bleed their CPU time away.
-
-Some tools to assist in creation of new bubbles are included in the source
-distribution.  These can either be loaded with the \fI\-file\fP or
-\fI\-directory\fP options (if available) or they can be used in place
-of the distributed default bubble (bubble_default.c).
-You might like to copy these scripts to a permanent location and
-use them.  Read bubbles.README.
-
-Rendered bubbles are not supported on monochrome displays.  I'm not
-convinced that small bubbles, even dithered properly are going to look
-like anything more than a jumble of random dots.
-.SH BUGS
-There is a delay before something appears on the screen when using
-rendered bubbles.  The XPM library seems to take a \fBlong\fP time to make

-.SH NAME
-critical - Draw a system showing self-organizing criticality
-.SH SYNOPSIS
-.B critical
-[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-delay \fIseconds\fP] [\-random \fIboolean\fP] [\-ncolors \fIint\fP] [\-offset \fIint\fP] 
-.SH DESCRIPTION
-The \fIcritical\fP program displays a self-organizing critical system
-that gradually emerges from chaos.
-
-\fIcritical\fP performs a simulation on a two-dimensional array of
-integers.  The array is initialized to random values.  On each
-iteration, it draws a line to the array position with the greatest
-value.  It then replaces that location and the eight neighboring
-locations with randomly-selected values.
-
-The lines are initially random, but over time a chaotic
-self-organizing system evolves: areas of the screen which happen to
-have lower values are less likely to be updated to new values, and so
-the line tends to avoid those areas.  Eventually, the histogram of
-changes approaches the power-law curve typical of such systems.
-
-The simplest documented self-organizing system is the one-dimensional
-equivalent of \fIcritical\fP.
-
-I heard about this algorithm second-hand: apparently there was an
-article in \fIScientific American\fP describing it sometime in 1997.

-.SH DESCRIPTION
-The \fIdecayscreen\fP program creates a melting effect by randomly
-shifting rectangles around the screen.
-.SH OPTIONS
-.I decayscreen
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-mono 
-If on a color display, pretend we're on a monochrome display.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-delay \fImicroseconds\fP
-Slow it down.
-.TP 8
-.B \-mode \fImode\fP
-The direction in which the image should tend to slide.  Legal values are
-\fIrandom\fP (meaning pick one), \fIup\fP, \fIleft\fP, \fIright\fP, 
-\fIdown\fP, \fIupleft\fP, \fIdownleft\fP, \fIupright\fP, \fIdownright\fP, 
-\fIshuffle\fP (meaning perfer no particular direction), \fIin\fP (meaning
-move things toward the center), \fIout\fP (meaning move things away
-from the center), \fImelt\fP (meaning melt straight downward), and \fIstretch\fP 
-(meaning stretch the screen downward).
-.SH RESOURCES
-On some systems (currently, only SGIs), this program can, instead of grabbing
-a desktop image, grab a frame of video from an external camera and manipulate
-that instead.  The following resources control that.
-.PP
-.TP 8
-.B grabVideoProbability \fR(Float)\fP
-What portion of the time to grab video rather than a screen image, 
-between 0.0 and 1.0.  Defaults to 0.5, or half the time.
-.TP 8
-.B videoDevice \fR(Integer)\fP
-The number of the default video input device to check first.  If unspecified, 
-the default camera (from videopanel(1)) will be checked first.  After that, all
-other available video input devices will be checked in order.  
-
-The first one which produces a non-black image will be used.  If all images
-are black, the others will be re-checked a few times before giving up and
-falling back to simply grabbing a desktop image (but note that this takes a
-few seconds, so if you don't actually have any video sources hooked up, you
-should consider turning off video grabbing by setting
-\fBgrabVideoProbability\fP to 0.0.)
-.TP 8
-.B videoGain \fR(Float)\fP
-The amount by which to brighten the grabbed image.  This defaults to 2.2.

-[\-display \fIhost:display.screen\fP] [\-root] [\-window] [\-mono] [\-install] [\-noinstall] [\-visual \fIviz\fP] [\-colors \fIN\fP] [\-foreground \fIname\fP] [\-color\-shift \fIN\fP] [\-delay \fImicroseconds\fP] [\-holdtime \fIseconds\fP] [\-linewidth \fIN\fP] [\-min_circles \fIN\fP] [\-max_circles \fIN\fP] [\-min_speed \fInumber\fP] [\-max_speed \fInumber\fP] [\-harmonics \fIN\fP] [\-timestep \fInumber\fP] [\-divisor_poisson \fIprobability\fP] [\-size_factor_min \fInumber\fP] [\-size_factor_max \fInumber\fP]
-.SH DESCRIPTION
-The epicycle program draws the path traced out by a point on the edge
-of a circle.  That circle rotates around a point on the rim of another
-circle, and so on, several times.  The random curves produced can be
-simple or complex, convex or concave, but they are always closed
-curves (they never go in indefinitely).
-
-You can configure both the way the curves are drawn and the way in
-which the random sequence of circles is generated, either with
-command-line options or X resources.
-.SH OPTIONS
-.TP 8
-.B \-display \fIhost:display.screen\fP
-Specifies which X display we should use (see the section DISPLAY NAMES in
-.BR X (1)
-for more information about this option).
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-mono
-If on a color display, pretend we're on a monochrome display.
-If we're on a mono display, we have no choice.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-noinstall
-Don't install a private colormap for the window.
-.TP 8
-.B \-visual \fIviz\fP
-Specify which visual to use.  Legal values are the name of a visual
-class, or the id number (decimal or hex) of a specific visual.
-Possible choices include
-
-.RS
-default, best, mono, monochrome, gray, grey, color, staticgray, staticcolor, 
-truecolor, grayscale, greyscale, pseudocolor, directcolor, \fInumber\fP
-
-If a decimal or hexadecimal number is used, 
-.BR XGetVisualInfo (3X)
-is consulted to obtain the required visual.
-.RE
-.TP 8
-.B \-colors \fIN\fP
-How many colors should be used (if possible).  The colors are chosen
-randomly.
-.TP 8
-.B \-foreground \fIname\fP
-With 
-.BR \-mono ,
-this option selects the foreground colour.   
-.TP 8
-.B \-delay \fImicroseconds\fP
-Specifies the delay between drawing successive line segments of the
-path.   If you do not specify 
-.BR -sync ,
-some X servers may batch up several drawing operations together,
-producing a less smooth effect.   This is more likely to happen 
-in monochrome mode (on monochrome servers or when 
-.B \-mono 
-is specified).
-.TP 8
-.B \-holdtime \fIseconds\fP
-When the figure is complete, 
-.I epicycle
-pauses this number of seconds.
-.TP 8
-.B \-linewidth \fIN\fP
-Width in pixels of the body's track.   Specifying values greater than
-one may cause slower drawing.   The fastest value is usually zero,
-meaning one pixel.   
-.TP 8
-.B \-min_circles \fIN\fP
-Smallest number of epicycles in the figure.
-.TP 8
-.B \-max_circles \fIN\fP
-Largest number of epicycles in the figure.
-.TP 8
-.B \-min_speed \fInumber\fP
-Smallest possible value for the base speed of revolution of the
-epicycles.  The actual speeds of the epicycles vary from this down
-to
-.IB "min_speed / harmonics" .
-.TP 8
-.B \-max_speed \fInumber\fP
-Smallest possible value for the base speed of revolution of the 
-epicycles.
-.TP 8
-.B \-harmonics \fIN\fP
-Number of possible harmonics; the larger this value is, the greater
-the possible variety of possible speeds of epicycle.
-.TP 8
-.B \-timestep \fInumber\fP
-Decreasing this value will reduce the distance the body moves for
-each line segment, possibly producing a smoother figure.  Increasing
-it may produce faster results.  
-.TP 8
-.B \-divisor_poisson \fIprobability\fP
-Each epicycle rotates at a rate which is a factor of the base speed.
-The speed of each epicycle is the base speed divided by some integer
-between 1 and the value of the 
-.B \-harmonics 
-option.  This integer is decided by starting at 1 and tossing 
-a biased coin.  For each consecutive head, the value is incremented by
-one.  The integer will not be incremented above the value of the 
-.B \-harmonics
-option.  The argument of this option decides the bias of the coin; it
-is the probability that that coin will produce a head at any given toss.
-.TP 8
-.B \-size_factor_min \fInumber\fP
-Epicycles are always at least this factor smaller than their
-parents.  
-.TP 8
-.B \-size_factor_max \fInumber\fP
-Epicycles are never more than this factor smaller than their parents.

-.EE
-Before the drawing of the figure is begun, a preliminary calculation
-of the path is done in order to scale the radii of the epicycles so
-as to fit the figure on the screen or window.  For the sake of speed,
-This calculation is done with a larger timestep than the actual
-drawing.  The time-step used is the value of the
-.B \-timestep 
-option multiplied by the timestepCoarseFactor resource.  The default
-value of 1 will almost always work fast enough and so this resource
-is not available as a command-line option.
-.SH USER INTERFACE
-The program runs mostly without user interaction.  When running on the
-root window, no input is accepted.  When running in its own window,
-the program will exit if mouse button 3 is pressed.  If any other
-mouse button is pressed, the current figure will be abandoned and
-another will be started.
-.SH HISTORY
-The geometry of epicycles was perfected by Hipparchus of Rhodes at
-some time around 125 B.C., 185 years after the birth of Aristarchus of
-Samos, the inventor of the heliocentric universe model.  Hipparchus
-applied epicycles to the Sun and the Moon.  Ptolemy of Alexandria went
-on to apply them to what was then the known universe, at around 150
-A.D.  Copernicus went on to apply them to the heliocentric model at
-the beginning of the sixteenth century.  Johannes Kepler discovered
-that the planets actually move in elliptical orbits in about 1602.
-The inverse-square law of gravity was suggested by Boulliau in 1645.
-Isaac Newton's 
-.I Principia Mathematica
-was published in 1687, and proved that Kepler's laws derived from
-Newtonian gravitation.
-.SH BUGS
-The colour selection is re-done for every figure.  This may 
-generate too much network traffic for this program to work well 
-over slow or long links.

-.SH RESOURCES
-On some systems (currently, only SGIs), this program can, instead of grabbing
-a desktop image, grab a frame of video from an external camera and manipulate
-that instead.  The following resources control that.
-.PP
-.TP 8
-.B grabVideoProbability \fR(Float)\fP
-What portion of the time to grab video rather than a screen image, 
-between 0.0 and 1.0.  Defaults to 0.5, or half the time.
-.TP 8
-.B videoDevice \fR(Integer)\fP
-The number of the default video input device to check first.  If unspecified, 
-the default camera (from videopanel(1)) will be checked first.  After that, all
-other available video input devices will be checked in order.  
-
-The first one which produces a non-black image will be used.  If all images
-are black, the others will be re-checked a few times before giving up and
-falling back to simply grabbing a desktop image (but note that this takes a
-few seconds, so if you don't actually have any video sources hooked up, you
-should consider turning off video grabbing by setting
-\fBgrabVideoProbability\fP to 0.0.)
-.TP 8
-.B videoGain \fR(Float)\fP
-The amount by which to brighten the grabbed image.  This defaults to 2.2.

-.SH DESCRIPTION
-The \fImaze\fP program creates a "random" maze and then solves it with 
-graphical feedback. 
-.SH OPTIONS
-.I maze
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-grid\-size \fIpixels\fP
-The size of each block of the maze, in pixels; default is 0, meaning
-pick a random grid size.
-.TP 8
-.B \-live\-color \fIcolor\fP
-The color of the path.
-.TP 8
-.B \-dead\-color \fIcolor\fP
-The color of the failed path (it is also stippled with a 50% pattern.)
-.TP 8
-.B \-skip\-color \fIcolor\fP
-The maze solver will choose to not go down a path if it can "see" (in a
-straight line) that it is a dead end.  This is the color to use for paths
-that are skipped for this reason.
-.TP 8
-.B \-surround\-color \fIcolor\fP
-If the maze solver ever completely encloses an area within the maze, then
-it knows that the exit is not in there (and in fact the interior of that
-area might not even be reachable.)  It will mark out those cells using this
-color.
-.TP 8
-.B \-solve\-delay \fIinteger\fP
-Delay (in microseconds) between each step of the solution path.
-Default 5000, or about 1/200th second.
-.TP 8
-.B \-pre\-delay \fIinteger\fP
-Delay (in microseconds) between generating a maze and starting to solve it.
-Default 2000000 (2 seconds.)
-.TP 8
-.B \-post\-delay \fIinteger\fP
-Delay (in microseconds) after solving a maze and before generating a new one.
-Default 4000000 (4 seconds.)
-.TP 8
-.B \-generator \fInum\fP
-Sets the algorithm that will be used to generate the mazes. The
-default is \-1, which randomly selects an algorithm for each maze that
-is generated. Generator 0 is the original one, and works by walking
-around randomly until we hit a place we've been before, then
-backtracking and trying a new direction somewhere. Generator 1 picks a
-random spot in the maze, then draws a straight wall from that spot in
-a random direction until it hits another wall (and continues until the
-maze is complete). Generator 2 is based on sets. Initially all cells
-are in different sets. Then two neighboring cells are chosen and if
-they are in different sets, their sets are joined. If they were in the
-same set, a wall is built between them. This continues until the maze is
-complete. 
-
-All generators generate mazes with a certain 'characteristic'. See if you
-can spot them!
-.TP 8
-.B \-max\-length \fInum\fP
-Controls the maximum length of walls drawn in one go by generator 1.
-.TP 8
-.B \-bridge
-.TP 8
-.B \-no\-bridge
-Controls whether or not a 'bridge' will appear over the logo.
-.PP
-Clicking the mouse in the maze window controls it.
-.TP 16
-.B "LeftButton
-Clears the window and restarts maze.
-.TP 16
-.B MiddleButton
-Pause or unpause the program.
-.TP 16
-.B RightButton
-Exit.
-.SH BUGS
-Expose events force a restart of maze.
-
-Mouse actions are based on "raw" values (Button1, Button2 and Button3)
-instead of using the pointer map.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.

-.SH SYNOPSIS

-
-.SH DESCRIPTION
-The \fIpenrose\fP program draws quasiperiodic tilings.
-
-See Onoda, Steinhardt, DiVincenzo and Socolar in
-Phys. Rev. Lett. 60, #25, 1988 or
-Strandburg in Computers in Physics, Sep/Oct 1991.
-
-This implementation uses the simpler version of the growth
-algorithm, i.e., if there are no forced vertices, a randomly chosen
-tile is added to a randomly chosen vertex (no preference for those
-108 degree angles).
-
-There are two essential differences to the algorithm presented in
-the literature: First, we do not allow the tiling to enclose an
-untiled area.  Whenever this is in danger of happening, we just
-do not add the tile, hoping for a better random choice the next
-time.  Second, when choosing a vertex randomly, we will take
-one that lies withing the viewport if available.  If this seems to
-cause enclosures in the forced rule case, we will allow invisible
-vertices to be chosen.
-
-Tiling is restarted whenever one of the following happens: there
-are no incomplete vertices within the viewport or the tiling has
-extended a window's length beyond the edge of the window
-horizontally or vertically or forced rule choice has failed 100
-times due to areas about to become enclosed.
-
-Although quasiperiodic tilings are produced, the tiles themselves are
-not penrose tiles (darts and kites). In contrast to penrose tiles,
-these tiles can be arranged to form a periodic tiling.
-

-.I penrose
-accepts the following options:
-.TP 8

-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8

-.SH DESCRIPTION
-The \fIqix\fP program bounces a series of line segments around its window.

-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-segments \fIinteger\fP
-How many line segments should be drawn.  Default 50.
-.TP 8
-.B \-spread \fIinteger\fP
-How far apart the endpoints of one segment should be from the next.
-Default 8.
-.TP 8
-.B \-size \fIinteger\fP
-The maximum distance one endpoint of a segment is allowed to be from
-the opposite end of that segment.  Default 0, meaning unlimited.
-.TP 8
-.B \-count \fIinteger\fP
-How many qixes to draw.  Default 1.
-.TP 8
-.B \-color\-shift \fIdegrees\fP
-If on a color display, the color of the line segments will cycle through
-the spectrum.  This specifies how far the hue of each segment should be
-from the next, in degrees on the HSV wheel.  Default 3.
-.TP 8
-.B \-delay \fImicroseconds\fP
-How much of a delay should be introduced between steps of the animation.
-Default 25000, or about 0.025 seconds.
-.TP 8
-.B \-random
-The \fIqix\fP will wander around the screen semi-randomly.  This is the
-default.
-.TP 8
-.B \-linear
-The opposite of \fI\-random\fP: the \fIqix\fP will travel in straight lines
-until it reaches a wall, and then it will bounce.
-.TP 8
-.B \-solid
-If this is specified, then the area between the line segments will be filled
-in with the appropriate color, instead of the \fIqix\fP simply being composed
-of one-pixel-wide line segments.  This option looks really good in color.
-.TP 8
-.B \-hollow
-The opposite of \fI\-solid\fP; this is the default.
-.TP 8
-.B \-xor
-If this is specified, then qix segments will be drawn and erased with xor,
-instead of being drawn in some color and erased in the background color.
-This implies \fI\-mono\fP, in that only two colors can be used.
-.TP 8
-.B \-transparent
-If this is specified, and \fI\-count\fP is greater than 1, then each qix
-will be drawn in one color, and when they overlap, the colors will be mixed.
-This looks best in conjuction with \fI\-solid\fP.
-.TP 8
-.B \-non\-transparent
-Turns off \fI\-transparent\fP.
-.TP 8
-.B \-additive
-If \fI\-transparent\fP is specified, then this option means that the colors
-will be mixed using an additive color model, as if the qixes were projected
-light.  This is the default.
-.TP 8
-.B \-subtractive
-If \fI\-transparent\fP is specified, then this option means that the
-colors will be mixed using a subtractive color model, as if the qixes were
-translucent filters.
-.TP 8
-.B \-poly \fIint\fP
-How many vertices each qix-line should have: the default is 2, meaning the
-traditional qix line shape.  Three will yield triangles, and so on.
-.TP 8
-.B \-gravity
-.TP 8
-.B \-no\-gravity
-Whether there should be downward attraction.  For example, the
-options
-.B \-gravity \-linear
-will make everything move in nice smooth parabolas.
-Gravity is off by default.

-.SH DESCRIPTION
-
-The \fIrd-bomb\fP program draws reaction/diffusion textures.  The code
-is derived from the 'd' mode of the "bomb" visual musical instrument
-(see http://www.cs.cmu.edu/~spot/bomb.html).  I got the equations from
-xmorphia (http://www.ccsf.caltech.edu/ismap/image.html), which is
-based on a version of the Gray-Scott model taken from:
-    John E. Pearson "Complex Patterns in a Simple System"
-    Science, 261,189, 9 July 1993.
-
-If the frame-rate is too low, consider decreasing the width and height
-of the tile, or decreasing the size of the active part of the screen.
-
-.SH OPTIONS
-
-If one of the reaction, diffusion, radius, and palette options is set
-to a negative value, then that option will be set to a random
-appropriate value.
-
-Be sure to try "-speed 1 -size 0.1 -epoch 3000".

-.SH DESCRIPTION
-The \fIslidescreen\fP program takes an image of the screen, divides it into
-a grid, deletes a random square of that grid, and then randomly slides 
-one of the neighbors of this "hole" into the hole (and repeat.)
-.SH OPTIONS
-.I slidescreen
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window.  This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-grid-size \fIpixels\fP
-The size of the grid cells.  Default 70 pixels.
-.TP 8
-.B \-ibw \fIpixels\fP
-The size of the "gutter" between grid cells.  Default 1 pixel.
-.TP 8
-.B \-increment \fIpixels\fP
-How many pixels by which a piece should be moved when sliding to a new 
-location.  Default 10 pixels.
-.TP 8
-.B \-delay \fImicroseconds\fP
-How much of a delay should be introduced between steps of the animation of
-the motion of each segment.  Default 50000, which is 0.05 seconds.  This
-is closely related to the \fI\-increment\fP parameter.
-.TP 8
-.B \-delay \fImicroseconds\fP
-How much of a delay should be introduced between the end of the motion of
-one segment and the beginning of the motion of another.  Default 1000000,
-which is one second.
-.SH RESOURCES
-On some systems (currently, only SGIs), this program can, instead of grabbing
-a desktop image, grab a frame of video from an external camera and manipulate
-that instead.  The following resources control that.
-.PP
-.TP 8
-.B grabVideoProbability \fR(Float)\fP
-What portion of the time to grab video rather than a screen image, 
-between 0.0 and 1.0.  Defaults to 0.5, or half the time.
-.TP 8
-.B videoDevice \fR(Integer)\fP
-The number of the default video input device to check first.  If unspecified, 
-the default camera (from videopanel(1)) will be checked first.  After that, all
-other available video input devices will be checked in order.  
-
-The first one which produces a non-black image will be used.  If all images
-are black, the others will be re-checked a few times before giving up and
-falling back to simply grabbing a desktop image (but note that this takes a
-few seconds, so if you don't actually have any video sources hooked up, you
-should consider turning off video grabbing by setting
-\fBgrabVideoProbability\fP to 0.0.)
-.TP 8
-.B videoGain \fR(Float)\fP
-The amount by which to brighten the grabbed image.  This defaults to 2.2.
-.SH ENVIRONMENT

-[\-team-a-count \fIint\fP]
-[\-team-b-count \fIint\fP]
-.SH DESCRIPTION
-The \fIsonar\fP program displays a sonar scope on the computer's screen.
-This scope polls a sensor as the sweep goes around the scope and displays
-what it finds as bogies on the screen.  The program is designed to support
-different modes representing different types of sensors.  Currently the
-only implemented sensors are a simulator, and a network ping function that
-pings hosts and plots the results on the scope.
-.SH OPTIONS
-.I sonar
-understands the following options:
-.TP 8
-.B \-background \fIColor\fP
-The background Color of the screen not covered by the scope.
-.TP 8
-.B \-sweep\-color \fIColor\fP
-The color of the brightest part of the sweep.
-.TP 8
-.B \-scope\-color \fIColor\fP
-The color of the circular part of the scope.
-.TP 8
-.B \-grid\-color \fIColor\fP
-The color to the grid lines overlaying the scope.
-.TP 8
-.B \-text\-color \fIColor\fP
-The color of the text identifying bogies on the scope.
-.TP 8
-.B \-ttl \fIinteger\fP
-"Time to live": visible time of a Bogie. Try values between 10 (very short)
-and 100. 
-.TP 8
-.B \-mode \fIsimulation | ping\fP
-The sensor mode to use, the currently supported modes \fIsimulate\fP (the
-default) and \fIping\fP.
-.TP 8
-.B \-font \fIfont\fP
-The font used to display text on the scope.  Default "fixed".
-.TP 8
-.B \-ping\-timeout \fIint\fP
-The amount of time in milliseconds the program will wait for an answer
-to a ping.
-.TP 8
-.B \-ping\-source list | file | subnet
-Th source of the list of hosts to ping. Valid values are: \fIlist\fP,
-\fIfile\fP, \fIsubnet\fP.  The first two values are described below;
-and \fIsubnet\fP indicates that the sonar should ping all hosts in the
-same subnet as the current machine.  (All addresses are treated
-as class C nets, therefore this will at most ping 254 hosts.)
-.TP 8
-.B \-ping\-file \fIfilename\fP
-The path to a file listing the hosts to ping.  This file can be in the
-format used by \fI/etc/hosts\fP, or it can be any file that has host
-names as the first element on each line.  If you use ssh, try this:
-.EX
-sonar -mode ping -ping-file $HOME/.ssh/known_hosts
-.EE
-This is used only used when \fIpingSource\fP is set to \fBfile\fP.
-.TP 8
-.B \-ping\-list \fIlist\fP
-A comma separated list of hostnames, eg \fI"pinky,brain,dot"\fP.
-Only used when \fIpingSource\fP is set to \fBlist\fP.
-.TP 8
-.B \-team-a-name \fIstring\fP
-The name of team A, in simulation-mode.
-.TP 8
-.B \-team-b-name \fIstring\fP
-The name of team B, in simulation-mode.

-.SH NAME
-t3d \- clock using flying balls to display the time
-.SH SYNOPSIS
-t3d [ \f2 options\f1 ]...
-.SH DESCRIPTION
-.PP
-Time 3D is a clock. It uses flying balls to display the time. This
-balls move and wobble around to give you the impression your
-graphic workstation with its many XStones is doing something.
-.PP
-t3d uses mouse and keyboard to let you fly through the balls. Hit
-.B S
-to speed up, 
-.B A
-to slow down,
-.B Z
-to zoom in and
-.B X
-to zoom out.
-Use the
-.B left mouse button
-to rotate to the left and the
-.B right mouse button
-to rotate the view to the right. Use the
-.B middle mouse button
-to change the optical axis and the moving direction.
-.B 0
-(zero) will stop you.
-.B Q
-quits.
-.PP
-.SH OPTIONS
-.TP
-.BI "-move " "factor"
-Modifies the direction move of t3d. The clock looks 30 degrees*
-.I factor
-to the left and to the right periodically.
-.TP
-.BI "-wobble " "factor"
-Modifies the wobbling (sounds nice :-) of t3d by multiplying the
-default deformation of the clock with
-.I factor.
-.TP
-.B -minutes
-Shows one small ball for every minute, instead of one for every 2.5 minutes.
-.TP
-.BI "-mag " "factor"
-Changes the magnification of t3d. By default, t3d draws a 200x200 image.
-A .I factor
-of 2 means, it will use a 400x400 image.
-.TP
-.BI "-cycle " "period"
-Sets the moving cycle to
-.I period
-seconds. By default, this value is 10 seconds.
-.TP
-.BI "-wait " "microsec"
-Inserts a wait after drawing one view of the clock. By default, t3d waits
-40 ms after each drawing. This helps you to keep the performance loss
-small.
-.TP
-.BI "-fast " "precalc_radius"
-t3d uses bitmap copy to draw precalculated balls. You can specify the radius
-in pixels up to which t3d should precalculate balls. t3d will set a useful
-range by itself using the magnification when it is started.
-.TP
-.B -colcycle
-Draws cyclic the color scale used for the balls in the background instead
-of the normal black.
-.TP
-.BI "-rgb " "red green blue"
-Selects the color in RGB color space of the lightning spot on the balls.
-All the other colors used for balls or
-.B -colcycle
-are less intensive colors of the same hue and saturation. All values
-in range of 0 to 1.
-.TP
-.BI "-hsv " "hue saturation value"
-Selects the color in HSV color space.
-.I hue
-is in degrees from 0 to 360, all other values in range from 0 to 1. It gives
-nice but rather unpredictable results, if you use a saturation of e.g. 2.
-Try it at your own risk.
-.TP
-.BI "-hsvcycle " "speed"
-Rotates the hue axis every 10 seconds*
-.I speed.
-.TP
-.B -help
-Prints a short usage message.

-Copy, modify, and distribute T3D either under GPL version 2 or newer, or

-
-.SH DISCLAIMER
-.PP
-T3D is not related to T3D(tm), the massive parallel Alpha--based
-supercomputer from Cray Research. T3D's name was invented in 1991,
-years before the project at Cray Research started. There is no
-relation from T3D to Cray's T3D, even the balls surrounding T3D on
-some posters weren't an inspiration for T3D. I don't know anything
-about the other way round.
-
-The programming style of T3D isn't intented as example of good style,
-but as example of how a fast prototyped demo may look like. T3D wasn't
-created to be useful, it was created to be nice.
-
-.SH KNOWN BUGS
-.PP
-There are no known bugs in T3D. Maybe there are bugs in X. Slight
-changes in the T3D sources are known to show these bugs, e.g. if
-you remove the (int) casting at the XFillArc x,y,w,h-coordinates...

-.SH SYNOPSIS
-.B vidwhacker
-[\-display \fIhost:display.screen\fP] [\-root] [\-window] [\-verbose] [\-stdin] [\-stdout] [\-delay seconds]
-.SH DESCRIPTION
-The \fIvidwhacker\fP program grabs a image from the system's video input,
-applies random image filters to it, and displays the result.  
-The \fIvidwhacker\fP program does not terminate until killed.
-It depends heavily on
-.BR xv (1)
-and the various PBM tools
-(e.g.,
-.BR ppmrelief (1).)
-.SH OPTIONS
-.I vidwhacker
-accepts the following options:
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-window
-Pop up a new window displaying the image.  When a new image has been fully
-processed, destroy that window and pop up a new one.  This is the default.
-.TP 8
-.B \-verbose
-Print diagnostics.
-.TP 8
-.B \-stdin
-Instead of grabbing an image from the system's video input, read an image
-to maniupulate from stdin.  This image must be in 
-.TP 8
-.B \-delay \fIseconds\fP
-How long to sleep between images.  Default 3 seconds (the actual
-elapsed time is significantly longer, due to processing time.)
-.BR ppm (5)
-format.  The program will still perform repeated random image 
-transformations, but it will always use this one image as its starting point.
-.TP 8
-.B \-stdout
-Instead of displaying the image on a window or on the root, write the new
-image on stdout, and exit.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
-.SH BUGS
-Grabbing video images is, of course, very system-dependent.  It works
-on SGIs, and on Linux systems that have the
-.BR qcam (1)
-program.  If your system does things differently, you'll need to edit
-the vidwhacker script (look for the \fIgrab()\fP function.)
-
-It's slow.
-.SH TO DO
-It might be interesting to rewrite this to use
-.BR gimp (1)
-plugins instead of the pbm tools.  It probably wouldn't be any faster,
-but there would be a wider variety of effects available.

-[\-display \fIhost:display.screen\fP] [\-root] [\-verbose]
-[\-delay \fIsecs\fP] [\-timeout \fIsecs\fP] [\-background \fIbg\fP]
-[\-filter \fIcommand\fP] [\-filter2 \fIcommand\fP]
-.SH DESCRIPTION
-The \fIwebcollage\fP program pulls random image off of the World Wide Web
-and scatters them on the root window.  It finds these images by doing
-random web searches, and extracting images from the returned pages.
-It places the images on the root window by using the 
-.BR xv (1),
-.BR giftopnm (1),
-and
-.BR djpeg (1)
-tools.
-
-\fIwebcollage\fP also works as a CGI program: simply make a symbolic
-link to the \fIwebcollage\fP executable called \fInph-webcollage.cgi\fP.
-If this program sees that it is being run as a CGI, then it will behave
-appropriately.  (The generated web page will list the images one after
-another, rather than tiling them together.)
-
-\fIwebcollage\fP is written in
-.BR perl (1)
-and requires Perl 5.
-.SH OPTIONS
-.I webcollage
-accepts the following options:
-.TP 8
-.B \-root
-Draw on the root window.  This option is manditory: drawing to a window
-other than the root window is not yet supported.
-.TP 8
-.B \-verbose \fRor\fP \-v
-Print diagnostics to stderr.  Multiple \fI-v\fP switches increase the
-amount of output.  \fI-v\fP will print out only the URLs of the 
-images; \fI-vv\fP will print all the commands being run; and \fI-vvv\fP
-will print more than you care about.
-.TP 8
-.B \-delay \fIseconds\fP
-How long to sleep between images.  Default 1 second.  (Remember that
-this program probably spends a lot of time waiting for the network.)
-.TP 8
-.B \-background \fIcolor-or-ppm\fP
-What to use for the background onto which images are pasted.  This may be
-a color name, a hexadecimal RGB specification in the form '#rrggbb', or 
-the name of a PPM file.
-.TP 8
-.B \-timeout \fIseconds\fP
-How long to wait for a URL to complete before giving up on it and
-moving on to the next one.
-Default 30 seconds.
-.TP 8
-.B \-filter \fIcommand\fP
-Filter all source images through this command.  The command must take
-a PPM file on stdin, and write a new PPM file to stdout.  One good 
-choice for a filter would be:
-.EX
-webcollage -root -filter 'vidwhacker -stdin -stdout'
-.EE
-.TP 8
-.B \-filter2 \fIcommand\fP
-Filter the \fIcomposite\fP image through this command.  The \fI-filter\fP
-option applies to the sub-images; the \fI-filter2\fP applies to the
-final, full-screen image.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
-.SH FILES AND URLS
-.TP
-.I /usr/dict/words \fRor\fP /usr/share/lib/dict/words
-To find the random words to feed to search engines.
-.PP
-.I http://random.yahoo.com/bin/ryl, http://image.altavista.com/
-To find random web pages.
-.SH BUGS
-When drawing on the root window, it always uses the default colormap.
-This is actually a limitation of xv.  But regardless, when using this
-program with xscreensaver, it must be given the \fBdefault-n\fP 
-visual specification (see the
-.BR xscreensaver (1)
-manual for more details.)
-
-Only the GIF and JPEG image formats are supported.
-
-Transparent and animating GIFs are not supported.
-
-It's slow.

-
-.SH DESCRIPTION
-The \fIjulia\fP program draws spinning, animating julia-set fractals.
-
-It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration 
-to plot the julia set, and sinusoidially varied parameters for the set,
-and plots parameters with a circle.
-
-One thing to note is that count is the \fIdepth\fP of the search tree,
-so the number of points computed is (2^count)-1.  I use 8 or 9 on a
-dx266 and it looks okay.  The sinusoidal variation of the parameter
-might not be as interesting as it could, but it still gives an idea 
-of the effect of the parameter.
-
-.SH OPTIONS
-.I julia

-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP
-Specify which visual to use.  Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-ncolors \fIinteger\fP
-How many colors should be used (if possible).  Default 200.
-The colors used cycle through the hue, making N stops around
-the color wheel.

-.B \-cycles \fIinteger\fP
-
-.TP 8
-.B \-count \fIinteger\fP
-
-.TP 8
-.B \-mouse

-.SH OPTIONS
-.TP 8
--random
-A good choice for use with xscreensaver: picks random parameters from 
-a built-in list.
-.TP 8
--C \fIn\fP
-Specifies the minimum color index to be used for negative exponents
-.TP
--D \fIn\fP
-Specifies the "dwell" or number of iterations over which to average in order
-to calculate the Lyapunov exponent. Default is 400.
-.TP
--B 
-Causes the stop, go, spin and quit buttons to be displayed.
-.TP
--H \fIn\fP
-Specifies the height of the window. Default is 256.
-.TP
--L 
-Indicates use log(x) + log(y) rather than log(xy).
-.TP
--M \fIr\fP
-Specifies the real value to compare exponent values to for indexing into
-a color wheel. The default value is 1.0.
-.TP
--O \fIn\fP
-Specifies the minimum color index to be used for positive exponents
-.TP
--R \fIp\fP
-Specifies pseudo-random forcing with probability \fIp\fP of using parameter
-value 'a'.
-.TP
--S \fIn\fP
-Specifies the "settle" or number of iterations prior to the beginning of
-the calculation of the Lyapunov exponent. Default is 200.
-.TP
--W \fIn\fP
-Specifies the width of the window. Default is 256.
-.TP
--a \fIr\fP
-Specifies the real value to use as the minimum parameter value of the 
-horizontal axis. Default is 3.0 for the logistic map.
-.TP
--b \fIn\fP
-Specifies the real value to use as the minimum parameter value of the 
-vertical axis. Default is 3.0 for the logistic map.
-.TP
--c \fIn\fP
-Selects one of six different color wheels to use. The default color
-wheel is a rainbow palette.
-.TP
--F \fI10101010\fP
-Specifies the "Function" forcing function to use. The example above would 
-alternate between iterating the circle and logistic maps. An argument of
-"-F 2323" would alternate between left and right logistic maps. The default
-is to only use the single specified map (see the description of -m).
-.TP
--f \fIabbabaab\fP
-Specifies the forcing function to use. The default is to alternate between
-the "a" parameter and the "b" parameter.
-.TP
--h \fIr\fP
-Specifies the real value to be used as the range over which the vertical
-parameter values vary. The default is 1.0.
-.TP
--i \fIr\fP
-Specifies the real value of the initial condition to use. Default is 0.05.
-.TP
--m \fIn\fP
-Selects between available non-linear maps of the unit interval. A value of
-0 specifies the logistic map. A value of 1, the circle map. A value of 2,
-the left-logistic. A value of 3, the right-logistic. A value of 4, the
-double-logistic. The default is 0, the logistic map.
-.TP
--o \fIfilename\fP
-Specifies the output filename to be used. If the -o option is given, this
-file will automatically be written out at the completion of the drawing.
-If it is not specified, a default filename of lyap.out is used and only
-written if the 'f' or 'F' keys are pressed during a run. The format of the
-output file is PPM for color and PGM for monochrom. The parameters used to
-calculate the picture are included as comments at the beginning of the output
-file.
-.TP
--p
-Switches color indices for negative and positive exponents. Generally,
-causes negative exponents to be displayed in more detail while darkening
-and narrowing the color range for positive exponents. This can be toggled
-during runtime by pressing the 'p' key.
-.TP
--r \fIn\fP
-Specifies the maximum rgb value to be used. Default is 35000.
-.TP
--s \fIn\fP
-Specifies the length of the color wheel spin.
-.TP
--u
-Produces a usage message.
-.TP
--v 
-Prints out the various values to be used and exits.
-.TP
--w \fIr\fP
-Specifies the real value to be used as the range over which the horizontal
-parameter values vary. The default is 1.0.

-.SH DESCRIPTION
-The \fIxscreensaver\-command\fP program controls a running \fIxscreensaver\fP
-process by sending it client-messages.
-
-.BR xscreensaver (1)
-has a client-server model: the xscreensaver process is a
-daemon that runs in the background; it is controlled by other
-foreground programs such as \fIxscreensaver-command\fP and
-.BR xscreensaver\-demo (1).
-
-This program, \fIxscreensaver-command\fP, is a command-line-oriented tool; the 
-.BR xscreensaver\-demo (1).
-program is a graphical tool.
-.SH OPTIONS
-.I xscreensaver-command
-accepts the following command-line options:
-.TP 8
-.B \-help
-Prints a brief summary of command-line options.
-.TP 8
-.B \-demo
-This just launches the
-.BR xscreensaver\-demo (1)
-program, in which one can experiment with the various graphics hacks
-available, and edit parameters.
-.TP 8
-.B \-demo \fP\fInumber\fP
-When the \fI\-demo\fP option is followed by an integer, it instructs 
-the \fIxscreensaver\fP daemon to run that hack, and wait for the user
-to click the mouse before deactivating (i.e., mouse motion does not
-deactivate.)  This is the mechanism by which
-.BR xscreensaver\-demo (1)
-communicates with the
-.BR xscreensaver (1)
-daemon.  (The first hack in the list is numbered 1, not 0.)
-.TP 8
-.B \-prefs
-Like the no-argument form of \fI\-demo\fP, but brings up that program's
-Preferences panel by default.
-.TP 8
-.B \-activate
-Tell xscreensaver to turn on immediately (that is, blank the screen, as if
-the user had been idle for long enough.)  The screensaver will deactivate as
-soon as there is any user activity, as usual.
-
-It is useful to run this from a menu; you may wish to run it as
-.EX
-sleep 5 ; xscreensaver-command -activate
-.EE
-to be sure that you have time to take your hand off the mouse before
-the screensaver comes on.  (Because if you jiggle the mouse, xscreensaver
-will notice, and deactivate.)
-.TP 8
-.B \-deactivate
-If the screensaver is active (the screen is blanked), this command will
-deactivate it just as if there had been keyboard or mouse activity.  
-If locking is enabled, then the screensaver will prompt for a password
-as usual.
-.TP 8
-.B \-cycle
-If the screensaver is active (the screen is blanked), then stop the current
-graphics demo and run a new one (chosen randomly.)
-.TP 8
-.B \-next
-This is like either \fI\-activate\fP or \fI\-cycle\fP, depending on which is
-more appropriate, except that the graphics hack that will be run is the next
-one in the list, instead of a randomly-chosen one.  In other words, 
-repeatedly executing -next will cause the xscreensaver process to invoke each
-graphics demo sequentially.  (Though using the \fI\-demo\fP option is probably
-an easier way to accomplish that.)
-.TP 8
-.B \-prev
-This is like \fI\-next\fP, but cycles in the other direction.
-.TP 8
-.B \-select \fInumber\fP
-Like \fI\-activate\fP, but runs the \fIN\fPth element in the list of hacks.
-By knowing what is in the \fIprograms\fP list, and in what order, you can use
-this to activate the screensaver with a particular graphics demo.  (The first
-element in the list is numbered 1, not 0.)
-.TP 8
-.B \-exit
-Causes the xscreensaver process to exit gracefully.  This is roughly the same
-as killing the process with
-.BR kill (1),
-but it is easier, since you don't need to first figure out the pid.  
-
-.B Warning:
-never use \fIkill -9\fP with \fIxscreensaver\fP while the screensaver is
-active.  If you are using a virtual root window manager, that can leave
-things in an inconsistent state, and you may need to restart your window
-manager to repair the damage.
-.TP 8
-.B \-lock
-Tells the running xscreensaver process to lock the screen immediately.  
-This is like \fI\-activate\fP, but forces locking as well, even if locking
-is not the default (that is, even if xscreensaver's \fIlock\fP resource is
-false, and even if the \fIlockTimeout\fP resource is non-zero.)
-
-Note that locking doesn't work unless the \fIxscreensaver\fP process is
-running as you.  See 
-.BR xscreensaver (1)
-for details.
-.TP 8
-.B \-throttle
-Temporarily switch to ``blank screen'' mode, and don't run any display modes
-at all, until the screensaver is next de-activated.  This is useful if you're
-using a machine remotely, and you find that some display modes are using too
-much CPU.  
-
-(If you want to do this \fIpermanently\fP, that is, you want the screen saver
-to only blank the screen and not run demos at all, then set the \fIprograms\fP
-resource to an empty list:  See
-.BR xscreensaver (1)
-for details.)
-.TP 8
-.B \-unthrottle
-Turn `-throttle' mode off and resume normal behavior.
-.TP 8
-.B \-version
-Prints the version of xscreensaver that is currently running on the display:
-that is, the actual version number of the running xscreensaver background 
-process, rather than the version number of xscreensaver-command.  (To see
-the version number of \fIxscreensaver-command\fP itself, use 
-the \fI\-help\fP option.)
-.TP 8
-.B \-time
-Prints the time at which the screensaver last activated or 
-deactivated (roughly, how long the user has been idle or non-idle: but 
-not quite, since it only tells you when the screen became blanked or
-un-blanked.)
-.TP 8
-.B \-restart
-Causes the screensaver process to exit and then restart with the same command
-line arguments as last time.  Do this after you've changed the resource
-database, to cause xscreensaver to notice the changes.
-
-.B Warning:
-if you have a \fI.xscreensaver\fP file, this might not do what you 
-expect.  You're probably better off killing the existing 
-xscreensaver (with \fIxscreensaver\-command -exit\fP) and then
-launching it again.
-
-The important point is, you need to make sure that the xscreensaver 
-process is running as you.  If it's not, it won't be reading the 
-right \fI.xscreensaver\fP file.
-.SH DIAGNOSTICS
-If an error occurs while communicating with the \fIxscreensaver\fP daemon, or
-if the daemon reports an error, a diagnostic message will be printed to
-stderr, and \fIxscreensaver-command\fP will exit with a non-zero value.  If
-the command is accepted, an indication of this will be printed to stdout, and
-the exit value will be zero.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the host and display number of the screen whose saver is
-to be manipulated.
-.TP 8
-.B PATH
-to find the executable to restart (for the \fI\-restart\fP command).  
-Note that this variable is consulted in the environment of 
-the \fIxscreensaver\fP process, not the \fIxscreensaver-command\fP process.

-.SH NAME
-xscreensaver-demo - interactively control the background xscreensaver daemon
-.SH SYNOPSIS
-.B xscreensaver\-demo
-[\-display \fIhost:display.screen\fP] [\-prefs] [\-xrm \fIresources\fP]
-.SH DESCRIPTION
-The \fIxscreensaver\-demo\fP program is a graphical front-end for 
-setting the parameters used by the background
-.BR xscreensaver (1)
-daemon.
-It is essentially two things: a tool for editing the \fI~/.xscreensaver\fP
-file; and a tool for demoing the various graphics hacks that 
-the \fIxscreensaver\fP daemon will launch.
-
-The main dialog box contains a scrolling list, a text field, and a number 
-of buttons.  
-
-Double-clicking on one of the programs in the list will run it.  The screen
-will go black, and the program will run in full-screen mode, just as it would
-if the \fIxscreensaver\fP daemon had launched it.  Clicking the mouse again
-will stop the demo and un-blank the screen, making the dialog box visible 
-again.
-
-Single-clicking in the list will place the indicated program and its args
-in the text field to be edited.  Edit the arguments and hit return to run
-the program with the parameters you have specified.  This will also save
-your changes to your \fI~/.xscreensaver\fP file: so any changes you make
-in this way are persistent.
-
-If one of the lines in the scrolling list begins with the character "-",
-then that means that the program is disabled: \fIxscreensaver\fP will not
-select it to be run (though you can still try it out by clicking on it.)
-Rather than just deleting the programs you don't want to run, you might
-want to disable them in this way instead, so that you can more easily change
-your mind later.
-
-If the line begins with the name of a visual, followed by a colon, then
-that program will only be run on that kind of visual.  For example, you can
-specify that a particular program should only be run if color is available,
-and another should only be run in monochrome.  See the discussion of 
-the \fIprograms\fP parameter in the \fIConfiguration\fP section of the
-.BR xscreensaver (1)
-manual.
-
-The buttons are:
-.TP 8
-.B Run Next
-Clicking this button will run the next program in the list after the 
-currently-selected one, and will wrap around to the top when it reaches
-the bottom.
-.TP 8
-.B Run Previous
-Opposite of Run Next; at the top, it wraps around to the bottom.
-.TP 8
-.B Preferences
-This pops up a second dialog box, in which you have the option to 
-interactively change most of the screensaver's operational parameters,
-such as its timeouts, and whether it should lock the screen.  When you
-click OK, your chosen settings will take effect immediately, and will
-also be saved to the \fI~/.xscreensaver\fP file in your home directory,
-so that the settings will persist next time.
-.TP 8
-.B Quit
-Exits the \fIxscreensaver-demo\fP program.  The background \fIxscreensaver\fP
-daemon will continue running as before.
-.P
-The Preferences dialog box lets you change the following settings.
-
-(There are more settings available, but these are the most commonly used
-ones; see the manual for
-.BR xscreensaver (1)
-for other parameters that can be set by editing the \fI~/.xscreensaver\fP
-file, or the X resource database.)
-.TP 8
-.B Saver Timeout
-After the user has been idle this long, the \fIxscreensaver\fP daemon
-will blank the screen.
-.TP 8
-.B Cycle Timeout
-After the screensaver has been running for this long, the currently
-running graphics demo will be killed, and a new one started.  
-If this is 0, then the graphics demo will never be changed:
-only one demo will run until the screensaver is deactivated by user 
-activity.
-.TP 8
-.B Verbose\ 
-Whether to print lots of debugging information.
-.TP 8
-.B Install Colormap
-Whether to install a private colormap while the screensaver is active, so
-that the graphics hacks can get as many colors as possible.  (This only
-applies when the screen's default visual is being used, since non-default
-visuals get their own colormaps automatically.)  This can also be overridden
-on a per-demo basis.
-.TP 8
-.B Fade Colormap
-If selected, then when the screensaver activates, the current contents
-of the screen will fade to black instead of simply winking out.  This only
-works on displays with writable colormaps, that is, if the screen's default
-visual is a PseudoColor visual.  A fade will also be done when
-switching graphics hacks (when the \fICycle Timeout\fP expires.)
-.TP 8
-.B Unfade Colormap
-The complement to \fIFade Colormap\fP: if selected, then when the screensaver
-deactivates, the original contents of the screen will fade in from black
-instead of appearing immediately.  This only works on displays with writable
-colormaps, and when \fIFade Colormap\fP is also selected.
-.TP 8
-.B Fade Duration
-When fading or unfading are selected, this controls how long the fade will
-take.
-.TP 8
-.B Fade Ticks
-This controls how many times a second the colormap will be changed to 
-effect a fade.  Higher numbers yield smoother fades, but may make the
-fades take longer than the specified number of seconds, if your server
-isn't fast enough to keep up.
-.TP 8
-.B Require Password
-Whether the screen saver should lock the screen when it activates.
-.TP 8
-.B Lock Timeout
-If \fIRequire Password\fP is selected, this controls the length of 
-the ``grace period'' between when the screensaver activates, and when the
-screen becomes locked.  For example, if this is 0:05:00, 
-and \fISaver Timeout\fP is 0:10:00, then after 10 minutes, the screen 
-would blank.  If there was user  activity at 12 minutes, no password
-would be required to un-blank the screen.  But, if there was user activity
-at 15 minutes or later (that is, \fILock Timeout\fP minutes after 
-activation) then a password would be required.  The default is 0, meaning
-that if locking is enabled, then a password will be required as soon as the 
-screen blanks.
-.TP 8
-.B Password Timeout
-When the screensaver is prompting for a password, the prompt dialog box will
-stay on the screen for this long before giving up, and reverting to 
-screen-saving mode.
-.SH COMMAND-LINE OPTIONS
-.I xscreensaver\-demo
-accepts the following command line options.
-.TP 8
-.B \-display \fIhost:display.screen\fP
-The X display to use.  The \fIxscreensaver\-demo\fP program will open its
-window on that display, and also control the \fIxscreensaver\fP daemon that
-is managing that same display.
-.TP 8
-.B \-prefs
-Start up in Preferences mode: this is just like launching the program with
-no arguments, and then pressing the \fIPreferences\fP button.
-.P
-It is important that the \fIxscreensaver\fP and \fIxscreensaver\-demo\fP
-processes be running on the same machine, or at least, on two machines
-that share a file system.  When \fIxscreensaver\-demo\fP writes a new version
-of the \fI~/.xscreensaver\fP file, it's important that the \fIxscreensaver\fP
-see that same file.  If the two processes are seeing 
-different \fI~/.xscreensaver\fP files, things will malfunction.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B PATH
-to find the sub-programs to run.  However, note that the sub-programs 
-are actually launched by the \fIxscreensaver\fP daemon, not 
-by \fIxscreensaver-demo\fP itself.  So, what matters is what \fB$PATH\fP
-the \fIxscreensaver\fP program sees.
-.TP 8
-.B HOME
-for the directory in which to read and write the \fI.xscreensaver\fP file.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.

-.SH DESCRIPTION
-The \fIxscreensaver\fP program waits until the keyboard and mouse have been 
-idle for a period, and then runs a graphics demo chosen at random.  It 
-turns off as soon as there is any mouse or keyboard activity.
-
-This program can lock your terminal in order to prevent others from using it,
-though its default mode of operation is merely to display pretty pictures on
-your screen when it is not in use.  
-
-The benefit that this program has over the combination of the
-.BR xlock (1)
-and
-.BR xautolock (1)
-programs is the ease with which new graphics hacks can be installed.  You
-don't need to recompile (or even re-run) this program to add a new display
-mode.
-.SH GETTING STARTED
-For the impatient, try this:
-.EX
-xscreensaver &
-xscreensaver-demo
-.EE
-The
-.BR xscreensaver-demo (1)
-program should pop up a dialog box that lets you experiment with the
-xscreensaver settings and graphics modes.
-
-.B Note:
-unlike
-.BR xlock (1),
-xscreensaver has a client-server model: the \fIxscreensaver\fP program is a
-daemon that runs in the background; it is controlled by the foreground
-.BR xscreensaver-demo (1)
-and
-.BR xscreensaver-command (1)
-programs.
-.SH CONFIGURATION
-Options to \fIxscreensaver\fP are specified in one of two places: in 
-a \fI.xscreensaver\fP file in your home directory; or in the X resource
-database.  If the \fI.xscreensaver\fP file exists, it overrides any settings
-in the resource database.  
-
-The syntax of the \fI.xscreensaver\fP file is similar to that of
-the \fI.Xdefaults\fP file; for example, to set the \fItimeout\fP paramter
-in the \fI.xscreensaver\fP file, you would write the following:
-.EX
-timeout: 5
-.EE
-whereas, in the \fI.Xdefaults\fP file, you would write
-.EX
-xscreensaver.timeout: 5
-.EE
-If you change a setting in the \fI.xscreensaver\fP file while xscreensaver
-is already running, it will notice this, and reload the file.  (The file will
-be reloaded the next time the screen saver needs to take some action, such as
-blanking or unblanking the screen, or picking a new graphics mode.)
-
-If you change a setting in your X resource database, or if you want
-xscreensaver to notice your changes immediately instead of the next time
-it wakes up, then you will need to tell the running xscreensaver process
-to re-initialize itself, like so:
-.EX
-xscreensaver-command -restart
-.EE
-Note that if you changed the \fI.Xdefaults\fP file, you might also need to run
-.BR xrdb (1):
-.EX
-xrdb < ~/.Xdefaults
-.EE
-If you want to set the system-wide defaults, then make your edits to
-the xscreensaver app-defaults file, which should have been installed
-when xscreensaver itself was installed.  The app-defaults file will
-usually be named /usr/lib/X11/app-defaults/XScreenSaver, but different
-systems might keep it in a different place (for example,
-/usr/openwin/lib/app-defaults/XScreenSaver on Solaris.)
-
-When settings are changed in the Preferences dialog box (see above)
-the current settings will be written to the \fI.xscreensaver\fP file.
-(The \fI.Xdefaults\fP file and the app-defaults file will never be
-written by xscreensaver itself.)
-.PP
-.TP 8
-.B timeout\fP (class \fBTime\fP)
-The screensaver will activate (blank the screen) after the keyboard and
-mouse have been idle for this many minutes.  Default 10 minutes.
-.TP 8
-.B cycle\fP (class \fBTime\fP)
-After the screensaver has been running for this many minutes, the currently
-running graphics-hack sub-process will be killed (with \fBSIGTERM\fP), and a
-new one started.  If this is 0, then the graphics hack will never be changed:
-only one demo will run until the screensaver is deactivated by user activity.
-Default 10 minutes.
-.TP 8
-.B lock\fP (class \fBBoolean\fP)
-Enable locking: before the screensaver will turn off, it will require you 
-to type the password of the logged-in user (really, the person who ran
-xscreensaver), or the root password.  (\fBNote:\fP this doesn't work if the
-screensaver is launched by
-.BR xdm (1)
-because it can't know the user-id of the logged-in user.  See 
-the ``\fIUsing XDM(1)\fP'' section, below.
-.TP 8
-.B lockTimeout\fP (class \fBTime\fP)
-If locking is enabled, this controls the length of the ``grace period''
-between when the screensaver activates, and when the screen becomes locked.
-For example, if this is 5, and \fI\-timeout\fP is 10, then after 10 minutes,
-the screen would blank.  If there was user activity at 12 minutes, no password
-would be required to un-blank the screen.  But, if there was user activity
-at 15 minutes or later (that is, \fI\-lock\-timeout\fP minutes after 
-activation) then a password would be required.  The default is 0, meaning
-that if locking is enabled, then a password will be required as soon as the 
-screen blanks.
-.TP 8
-.B passwdTimeout\fP (class \fBTime\fP)
-If the screen is locked, then this is how many seconds the password dialog box
-should be left on the screen before giving up (default 30 seconds.)  This
-should not be too large: the X server is grabbed for the duration that the
-password dialog box is up (for security purposes) and leaving the server 
-grabbed for too long can cause problems.
-.TP 8
-.B visualID\fP (class \fBVisualID\fP)
-Specify which X visual to use by default.  (Note carefully that this resource
-is called \fBvisualID\fP, not merely \fBvisual\fP; if you set the \fBvisual\fP
-resource instead, things will malfunction in obscure ways for obscure reasons.)
-
-Legal values for the \fBVisualID\fP resource are:
-.RS 8
-.TP 8
-.B default
-Use the screen's default visual (the visual of the root window.)  
-This is the default.
-.TP 8
-.B best
-Use the visual which supports the most colors.  Note, however, that the
-visual with the most colors might be a TrueColor visual, which does not
-support colormap animation.  Some programs have more interesting behavior
-when run on PseudoColor visuals than on TrueColor.
-.TP 8
-.B mono
-Use a monochrome visual, if there is one.
-.TP 8
-.B gray
-Use a grayscale or staticgray visual, if there is one and it has more than
-one plane (that is, it's not monochrome.)
-.TP 8
-.B color
-Use the best of the color visuals, if there are any.
-.TP 8
-.B GL
-Use the visual that is best for OpenGL programs.  (OpenGL programs have
-somewhat different requirements than other X programs.)
-.TP 8
-.I class
-where \fIclass\fP is one of \fBStaticGray\fP, \fBStaticColor\fP, 
-\fBTrueColor\fP, \fBGrayScale\fP, \fBPseudoColor\fP, or \fBDirectColor\fP.
-Selects the deepest visual of the given class.
-.TP 8
-.I number
-where \fInumber\fP (decimal or hex) is interpreted as a visual id number, 
-as reported by the
-.BR xdpyinfo (1)
-program; in this way you can have finer control over exactly which visual
-gets used, for example, to select a shallower one than would otherwise
-have been chosen.
-
-.RE
-.RS 8
-Note that this option specifies only the \fIdefault\fP visual that will
-be used: the visual used may be overridden on a program-by-program basis.
-See the description of the \fBprograms\fP resource, below.
-.RE
-.TP 8
-.B installColormap\fP (class \fBBoolean\fP)
-Install a private colormap while the screensaver is active, so that the
-graphics hacks can get as many colors as possible.  This is the 
-default.  (This only applies when the screen's default visual is being
-used, since non-default visuals get their own colormaps automatically.)
-This can also be overridden on a per-hack basis: see the discussion of
-the \fBdefault\-n\fP name in the section about the \fBprograms\fP resource.
-.TP 8
-.B verbose\fP (class \fBBoolean\fP)
-Whether to print diagnostics.  Default false.
-.TP 8
-.B timestamp\fP (class \fBBoolean\fP)
-Whether to print the time of day along with any other diagnostic messages.
-Default false.
-.TP 8
-.B splash\fP (class \fBBoolean\fP)
-Whether to display a splash screen at startup.  Default true.
-.TP 8
-.B splashDuration\fP (class \fBTime\fP)
-How long the splash screen should remain visible; default 5 seconds.
-.TP 8
-.B helpURL\fP (class \fBURL\fP)
-The splash screen has a \fIHelp\fP button on it.  When you press it, it will
-display the web page indicated here in your web browser.
-.TP 8
-.B loadURL\fP (class \fBLoadURL\fP)
-This is the shell command used to load a URL into your web browser.
-The default setting will load it into Netscape if it is already running,
-otherwise, will launch a new Netscape looking at the \fIhelpURL\fP.
-.TP 8
-.B demoCommand\fP (class \fBDemoCommand\fP)
-This is the shell command run when the \fIDemo\fP button on the splash window
-is pressed.  It defaults to \fIxscreensaver\-demo\fP.
-.TP 8
-.B prefsCommand\fP (class \fBPrefsCommand\fP)
-This is the shell command run when the \fIPrefs\fP button on the splash window
-is pressed.  It defaults to \fIxscreensaver\-demo\ \-prefs\fP.
-.TP 8
-.B nice\fP (class \fBNice\fP)
-The sub-processes created by \fIxscreensaver\fP will be ``niced'' to this
-level, so that they are given lower priority than other processes on the
-system, and don't increase the load unnecessarily.  The default is 10.  
-
-(Higher numbers mean lower priority; see 
-.BR nice (1)
-for details.)
-.TP 8
-.B fade\fP (class \fBBoolean\fP)
-If this is true, then when the screensaver activates, the current contents
-of the screen will fade to black instead of simply winking out.  This only
-works on displays with writable colormaps, that is, if the screen's default
-visual is a PseudoColor visual.  A fade will also be done when
-switching graphics hacks (when the \fIcycle\fP timer expires.)
-Default: true.  
-.TP 8
-.B unfade\fP (class \fBBoolean\fP)
-If this is true, then when the screensaver deactivates, the original contents
-of the screen will fade in from black instead of appearing immediately.  This
-only works on displays with writable colormaps, and if \fIfade\fP is true
-as well.  Default false.
-.TP 8
-.B fadeSeconds\fP (class \fBTime\fP)
-If \fIfade\fP is true, this is how long the fade will be in 
-seconds (default 3 seconds.)
-.TP 8
-.B fadeTicks\fP (class \fBInteger\fP)
-If \fIfade\fP is true, this is how many times a second the colormap will
-be changed to effect a fade.  Higher numbers yield smoother fades, but
-may make the fades take longer than the specified \fIfadeSeconds\fP if
-your server isn't fast enough to keep up.  Default 20.
-.TP 8
-.B captureStderr\fP (class \fBBoolean\fP)

-(This extension is only available for X11R4 and X11R5 systems, unfortunately.)
-.TP 8
-.B procInterrupts\fP (class \fBBoolean\fP)
-This resource controls whether the \fB/proc/interrupts\fP file should be
-consulted to decide whether the user is idle.  This is the default
-if \fIxscreensaver\fP has been compiled on a system which supports this
-mechanism (i.e., Linux systems.)  
-
-The benefit to doing this is that \fIxscreensaver\fP can note that the user
-is active even when the X console is not the active one: if the user is 
-typing in another virtual console, xscreensaver will notice that and will
-fail to activate.  For example, if you're playing Quake in VGA-mode, 
-xscreensaver won't wake up in the middle of your game and start competing 
-for CPU.
-
-The drawback to doing this is that perhaps you \fIreally do\fP want idleness
-on the X console to cause the X display to lock, even if there is activity
-on other virtual consoles.  If you want that, then set this option to False.

-.SH HOW IT WORKS
-When it is time to activate the screensaver, a full-screen black window is
-created on each screen of the display.  Each window is created in such a way
-that, to any subsequently-created programs, it will appear to be a ``virtual
-root'' window.  Because of this, any program which draws on the root 
-window (and which understands virtual roots) can be used as a screensaver.
-
-When the user becomes active again, the screensaver windows are unmapped, and
-the running subprocesses are killed by sending them \fBSIGTERM\fP.  This is 
-also how the subprocesses are killed when the screensaver decides that it's
-time to run a different demo: the old one is killed and a new one is launched.
-
-Before launching a subprocess, \fIxscreensaver\fP stores an appropriate value
-for \fB$DISPLAY\fP in the environment that the child will recieve.  (This is
-so that if you start \fIxscreensaver\fP with a \fI-display\fP argument, the
-programs which \fIxscreensaver\fP launches will draw on the same display;
-and so that the child will end up drawing on the appropriate screen of a
-multi-headed display.)
-
-When the screensaver turns off, or is killed, care is taken to restore 
-the ``real'' virtual root window if there is one.  Because of this, it is
-important that you not kill the screensaver process with \fIkill -9\fP if
-you are running a virtual-root window manager.  If you kill it with \-9,
-you may need to restart your window manager to repair the damage.  This
-isn't an issue if you aren't running a virtual-root window manager.
-
-For all the gory details, see the commentary at the top of xscreensaver.c.
-
-You can control a running screensaver process by using the
-.BR xscreensaver\-command (1)
-program (which see.)
-.SH POWER MANAGEMENT
-Modern X servers contain support to power down the monitor after an idle
-period.  If the monitor has powered down, then \fIxscreensaver\fP will
-notice this, and will not waste CPU by drawing graphics demos on a black
-screen.  An attempt will also be made to explicitly power the monitor
-back up as soon as user activity is detected.
-
-If your X server supports power management, then
-.BR xset (1)
-will accept a \fBdpms\fP option.  So, if you wanted \fIxscreensaver\fP
-to activate after 5 minutes, but you wanted your monitor to power down
-after one hour (3600 seconds) you would do this:
-.EX
-xset dpms 3600
-.EE
-See the man page for the
-.BR xset (1)
-program for details.  (Note that power management requires both software
-support in the X server, and hardware support in the monitor itself.)
-.SH USING XDM(1)
-You can run \fIxscreensaver\fP from your 
-.BR xdm (1)
-session, so that the screensaver will run even when nobody is logged 
-in on the console.
-
-The trick to using xscreensaver with \fIxdm\fP is this: keep in mind the 
-two very different states in which xscreensaver will be running:
-.RS 4
-.TP 3
-.B 1: Nobody logged in.
-
-If you're thinking of running xscreensaver from XDM at all, then it's 
-probably because you want graphics demos to be running on the console
-when nobody is logged in there.  In this case, xscreensaver will function
-only as a screen saver, not a screen locker: it doesn't make sense
-for xscreensaver to lock the screen, since nobody is logged in yet!
-The only thing on the screen is the XDM login prompt.
-.TP 3
-.B 2: Somebody logged in.
-
-Once someone has logged in through the XDM login window, the situation is
-very different.  For example: now it makes sense to lock the screen (and
-prompt for the logged in user's password); and now xscreensaver should
-consult that user's \fI~/.xscreensaver\fP file; and so on.
-.RE
-
-The difference between these two states comes down to a question of,
-which user is the \fIxscreensaver\fP process running as?  For the first
-state, it doesn't matter.  If you start \fIxscreensaver\fP in the usual
-XDM way, then xscreensaver will probably end up running as root, which 
-is fine for the first case (the ``nobody logged in'' case.)
-
-However, once someone is logged in, running as root is no longer fine:
-because xscreensaver will be consulting root's \fI.xscreensaver\fP file
-instead of that of the logged in user, and won't be prompting for the
-logged in user's password, and so on.  (This is not a security problem,
-it's just not what you want.)
-
-So, once someone has logged in, you want xscreensaver to be running as that
-user.  The way to accomplish this is to kill the old xscreensaver process
-and start a new one (as the new user.)
-
-The simplest way to accomplish all of this is as follows:
-.RS 4
-.TP 3
-.B 1: Launch xscreensaver before anyone logs in.
-
-To the file \fI/usr/lib/X11/xdm/Xsetup\fP, add the lines
-.EX
-xscreensaver-command -exit
-xscreensaver &
-.EE
-This will run xscreensaver as root, over the XDM login window.
-Moving the mouse will cause the screen to un-blank, and allow the user
-to type their password at XDM to log in.
-.TP 3
-.B 2: Restart xscreensaver when someone logs in.
-
-Near the top of the file \fI/usr/lib/X11/xdm/Xsession\fP, add those same lines:
-.EX
-xscreensaver-command -exit
-xscreensaver &
-.EE
-When someone logs in, this will kill off the existing (root) xscreensaver
-process, and start a new one, running as the user who has just logged in.
-If the user's .xscreensaver file requests locking, they'll get it.  They
-will also get their own choice of timeouts, and graphics demos, and so on.
-
-Alternately, each user could just put those lines in their 
-personal \fI~/.xsession\fP files.
-.RE
-
-Make sure you have \fB$PATH\fP set up correctly in the \fIXsetup\fP 
-and \fIXsession\fP scripts, or \fIxdm\fP won't be able to 
-find \fIxscreensaver\fP, and/or \fIxscreensaver\fP won't be able to 
-find its graphics demos.
-
-(If your system does not seem to be executing the \fIXsetup\fP file, you
-may need to configure it to do so: the traditional way to do this is
-to make that file the value of the \fIDisplayManager*setup\fP resource
-in the \fI/usr/lib/X11/xdm/xdm-config\fP file.  See the man page for
-.BR xdm (1)
-for more details.)
-
-It is safe to run \fIxscreensaver\fP as root (as \fIxdm\fP is likely to do.)  
-If run as root, \fIxscreensaver\fP changes its effective user and group ids 
-to something safe (like \fI"nobody"\fP) before connecting to the X server
-or launching user-specified programs.
-
-An unfortunate side effect of this (important) security precaution is that
-it may conflict with cookie-based authentication.
-
-If you get "connection refused" errors when running \fIxscreensaver\fP
-from \fIxdm\fP, then this probably means that you have
-.BR xauth (1)
-or some other security mechanism turned on.  One way around this is to
-add \fB"xhost\ +localhost"\fP to \fIXsetup\fP, just before \fIxscreensaver\fP
-is launched.  
-
-Note that this will give access to the X server to anyone capable of logging
-in to the local machine, so in some environments, this might not be 
-appropriate.  If turning off file-system-based access control is not
-acceptable, then running \fIxscreensaver\fP from the \fIXsetup\fP file
-might not be possible, and xscreensaver will only work when running as
-a normal, unprivileged user.
-
-For more information on the X server's access control mechanisms, see the
-man pages for
-.BR X (1),
-.BR Xsecurity (1),
-.BR xauth (1),
-and

-directly into the root menu.

-Other window managers are guaranteed to do things gratuitously differently.
-.SH BUGS
-Bugs?  There are no bugs.  Ok, well, maybe.  If you find one, please let
-me know.  http://www.jwz.org/xscreensaver/bugs.html explains how to
-construct the most useful bug reports.
-.TP 8
-.B Locking and XDM
-If xscreensaver has been launched from 
-.BR xdm (1)
-before anyone has logged in, you will need to kill and then restart the
-xscreensaver daemon after you have logged in, or you will be confused by
-the results.  (For example, locking won't work, and your \fI~/.xscreensaver\fP
-file will be ignored.)
-
-When you are logged in, you want the \fIxscreensaver\fP daemon to be 
-running under \fIyour\fP user id, not as root or some other user.
-
-If it has already been started by \fIxdm\fP, you can kill it by sending
-it the \fBexit\fP command, and then re-launching it as you, by putting
-something like the following in your personal X startup script:
-.EX
-xscreensaver-command -exit
-xscreensaver &
-.EE
-The ``\fIUsing XDM(1)\fP'' section, above, goes into more detail, and explains
-how to configure the system to do this for all users automatically.
-.TP 8
-.B Locking and root logins
-In order for it to be safe for xscreensaver to be launched by \fIxdm\fP,
-certain precautions had to be taken, among them that xscreensaver never
-runs as \fIroot\fP.  In particular, if it is launched as root (as \fIxdm\fP
-is likely to do), xscreensaver will disavow its privileges, and switch 
-itself to a safe user id (such as \fInobody\fP.)
-
-An implication of this is that if you log in as \fIroot\fP on the console, 
-xscreensaver will refuse to lock the screen (because it can't tell
-the difference between \fIroot\fP being logged in on the console, and a
-normal user being logged in on the console but xscreensaver having been 
-launched by the
-.BR xdm (1)
-.I Xsetup
-file.)
-
-The solution to this is simple: you shouldn't be logging in on the console
-as \fIroot\fP in the first place!  (What, are you crazy or something?)  
-
-Proper Unix hygiene dictates that you should log in as yourself, and
-.BR su (1)
-to \fIroot\fP as necessary.  People who spend their day logged in
-as \fIroot\fP are just begging for disaster.
-.TP 8
-.B XAUTH and XDM
-For xscreensaver to work when launched by
-.BR xdm (1),
-programs running on the local machine as user \fI"nobody"\fP must be
-able to connect to the X server.  This means that if you want to run
-xscreensaver on the console while nobody is logged in, you may need
-to disable cookie-based access control (and allow all users who can log
-in to the local machine to connect to the display.)  
-
-You should be sure that this is an acceptable thing to do in your
-environment before doing it.  See the ``\fIUsing XDM(1)\fP'' section, 
-above, for more details.
-
-If anyone has suggestions on how xscreensaver could be made to work with
-.BR xdm (1)
-without first turning off \fI.Xauthority\fP-based access control, please
-let me know.
-.TP 8
-.B Passwords
-If you get an error message at startup like ``couldn't get password
-of \fIuser\fP'' then this probably means that you're on a system in which 
-the
-.BR getpwent (3)
-library routine can only be effectively used by root.  If this is the case, 
-then \fIxscreensaver\fP must be installed as setuid to root in order for
-locking to work.  Care has been taken to make this a safe thing to do.  
-
-It also may mean that your system uses shadow passwords instead of the standard
-.BR getpwent (3)
-interface; in that case, you may need to change some options 
-with \fIconfigure\fP and recompile.
-
-If you change your password after xscreensaver has been launched, it will
-continue using your old password to unlock the screen until xscreensaver
-is restarted.  So, after you change your password, you'll have to do
-.EX
-xscreensaver-command -restart
-.EE
-to make \fIxscreensaver\fP notice.
-.TP 8
-.B PAM Passwords
-If your system uses PAM (Pluggable Authentication Modules), then in order
-for xscreensaver to use PAM properly, PAM must be told about xscreensaver.
-The xscreensaver installation process should update the PAM data (on Linux,
-by creating the file \fI/etc/pam.d/xscreensaver\fP for you, and on Solaris, 
-by telling you what lines to add to the \fI/etc/pam.conf\fP file.)  
-
-If the PAM configuration files do not know about xscreensaver, then 
-you \fImight\fP be in a situation where xscreensaver will refuse to ever
-unlock the screen.
-
-This is a design flaw in PAM (there is no way for a client to tell the
-difference between PAM responding ``I have never heard of your module,''
-and responding, ``you typed the wrong password.'')  As far as I can tell,
-there is no way for xscreensaver to automatically work around this, or
-detect the problem in advance, so if you have PAM, make sure it is
-configured correctly!
-.TP 8
-.B Colormap lossage: TWM
-The \fBinstallColormap\fP option doesn't work very well with the
-.BR twm (1)
-window manager and its descendants.  
-
-There is a race condition between the screensaver and this window manager,
-which can result in the screensaver's colormap not getting installed
-properly, meaning the graphics hacks will appear in essentially random
-colors.  (If the screen goes white instead of black, this is probably why.)
-
-The
-.BR mwm (1)
-and
-.BR olwm (1)
-window managers don't have this problem.  The race condition exists
-because X (really, ICCCM) does not provide a way for an OverrideRedirect 
-window to have its own colormap, short of grabbing the server (which is 
-neither a good idea, nor really possible with the current design.)  What 
-happens is that, as soon as xscreensaver installs its colormap, \fBtwm\fP 
-responds to the resultant \fBColormapNotify\fP event by re-instaling the 
-default colormap.  Apparently, \fBtwm\fP doesn't \fIalways\fP do this; it 
-seems to do it regularly if the screensaver is activated from a menu item, 
-but seems to not do it if the screensaver comes on of its own volition, or 
-is activated from another console.  
-.RS 8
-.TP 4
-.B Attention, window manager authors!
-You should only call
-.BR XInstallColormap (3)
-in response to user events.  That is, it is appropriate to install a colormap
-in response to \fBFocusIn\fP, \fBFocusOut\fP, \fBEnterNotify\fP, 
-and \fBLeaveNotify\fP events; but it is not appropriate to call it in
-response to \fBColormapNotify\fP events.  If you install colormaps in
-response to \fIapplication\fP actions as well as in response to \fIuser\fP
-actions, then you create the situation where it is impossible for 
-override-redirect applications (such as xscreensaver) to display their
-windows in the proper colors.
-.RE
-.TP 8
-.B Colormap lossage: XV, XAnim, XEarth
-Some programs don't operate properly on visuals other than the default one,
-or with colormaps other than the default one.  See the discussion of the
-magic "default-n" visual name in the description of the \fBprograms\fP 
-resource in the \fIConfiguration\fP section.  When programs only work with
-the default colormap, you need to use a syntax like this:
-.EX
-   default-n: xv -root image-1.gif -quit  \\n\\
-   default-n: xearth -nostars -wait 0     \\n\\
-.EE
-It would also work to turn off the \fBinstallColormap\fP option altogether,
-but that would deny extra colors to those programs that \fIcan\fP take
-advantage of them.
-.TP 8
-.B Machine Load
-Although this program ``nices'' the subprocesses that it starts, 
-graphics-intensive subprograms can still overload the machine by causing
-the X server process itself (which is not ``niced'') to suck a lot of 
-cycles.  Care should be taken to slow down programs intended for use as 
-screensavers by inserting strategic calls to
-.BR sleep (3)
-or
-.BR usleep (3)
-(or making liberal use of any \fI\-delay\fP options which the programs 
-may provide.)
-
-Note that the OpenGL-based graphics demos are real pigs on machines that
-don't have texture hardware.
-
-Also, an active screensaver will cause your X server to be pretty much 
-permanently swapped in; but the same is true of any program that draws
-periodically, like 
-.BR xclock (1)
-or
-.BR xload (1).
-.TP 8
-.B Latency and Responsiveness
-If the subprocess is drawing too quickly and the connection to the X
-server is a slow one (such as an X terminal running over a phone line) then 
-the screensaver might not turn off right away when the user becomes active
-again (the
-.BR ico (1)
-demo has this problem if being run in full-speed mode).  This can be
-alleviated by inserting strategic calls to
-.BR XSync (3)
-in code intended for use as a screensaver.  This prevents too much graphics
-activity from being buffered up.
-.TP 8
-.B XFree86's Magic Keystrokes
-The XFree86 X server traps certain magic keystrokes before client programs ever
-see them.  Two that are of note are Ctrl+Alt+Backspace, which causes 
-the X server to exit; and Ctrl+Alt+F\fIn\fP, which switches virtual consoles.
-The X server will respond to these keystrokes even if xscreensaver has the
-screen locked.  Depending on your setup, you might consider this a problem.
-
-Unfortunately, there is no way for xscreensaver itself to override the
-interpretation of these keys.  If you want to disable Ctrl+Alt+Backspace
-globally, you need to set the \fIDontZap\fP flag in 
-your \fI/etc/X11/XF86Config\fP file.  See the
-.BR XF86Config (5)
-manual for details.
-
-There is no way (as far as I can tell) to disable the VT-switching keystrokes.
-
-Some Linux systems come with a VT_LOCKSWITCH ioctl, that one could 
-theoretically use to prevent VT-switching while the screen is locked; 
-but unfortunately, this ioctl can only be used by root, which means
-that xscreensaver can't use it (since xscreensaver disavows its privileges
-shortly after startup, for security reasons.)
-
-Any suggestions for other solutions to this problem are welcome.
-.TP 8
-.B XView Clients
-Apparently there are some problems with XView programs getting confused
-and thinking that the screensaver window is the real root window even when
-the screensaver is not active: ClientMessages intended for the window manager
-are sent to the screensaver window instead.  This could be solved by making
-xscreensaver forward all unrecognised ClientMessages to the real root window,
-but there may be other problems as well.  If anyone has any insight on the
-cause of this problem, please let me know.  (XView is an X11 toolkit that 
-implements the (quite abominable) Sun OpenLook look-and-feel.)
-.TP 8
-.B MIT Extension and Fading
-The \fBMIT-SCREEN-SAVER\fP extension is junk.  Don't use it.
-
-When using the \fBMIT-SCREEN-SAVER\fP extension in conjunction with 
-the \fBfade\fP option, you'll notice an unattractive flicker just before 
-the fade begins.  This is because the server maps a black window just before 
-it tells the \fIxscreensaver\fP process to activate.  The \fIxscreensaver\fP 
-process immediately unmaps that window, but this results in a flicker.  I 
-haven't figured a way  to get around this; it seems to be a fundamental
-property of the (mis-) design of this server extension.
-
-It sure would be nice if someone would implement the \fBSGI SCREEN_SAVER\fP
-extension in XFree86; it's dead simple, and works far better than the
-overengineered and broken \fBMIT-SCREEN-SAVER\fP extension.
-.TP 8
-.B SGI Power Saver
-If you're running Irix 6.3, you might find that your monitor is powering down
-after an hour or two even if you've told it not to.  This is fixed by SGI
-patches 2447 and 2537.
-
-If you're running Irix 6.5, this bug is back.  I don't know a fix.
-.TP 8
-.B MesaGL and Voodoo Cards
-If you have a 3Dfx/Voodoo card, the default settings for xscreensaver will
-run the GL-based graphics demos in such a way that they will not take 
-advantage of the 3D acceleration hardware.  The solution is to change
-the \fBprograms\fP entries for the GL hacks from this:
-.EX
-       gears -root                        \\n\\
-.EE
-to this:
-.EX
-       MESA_GLX_FX=fullscreen  gears      \\n\\
-.EE
-That is, make sure that \fB$MESA_GLX_FX\fP is set to \fIfullscreen\fP, and
-don't tell the program to draw on the root window.  This may seem strange,
-but the setup used by Mesa and these kinds of cards \fIis\fP strange!
-
-For those who don't know, these cards work by sitting between your normal
-video card and the monitor, and seizing control of the monitor when it's 
-time to do 3D.  But this means that accelerated 3D only happens in full-screen
-mode (you can't do it in a window, and you can't see the output of 3D and 2D
-programs simultaniously), and that 3D will probably drive your monitor at a
-lower resolution, as well.  It's bizarre.
-
-If you find that GL programs only work properly when run as root, and not
-as normal users, then the problem is that your \fI/dev/3dfx\fP file is not
-configured properly.  Check the Linux 3Dfx FAQ.
-.TP 8
-.B Keyboard LEDs
-If \fIprocInterrupts\fP is on (which is the default on Linux systems) and
-you're using some program that toggles the state of your keyboard LEDs,
-xscreensaver won't work right: turning those LEDs on or off causes a 
-keyboard interrupt, which xscreensaver will interpret as user activity.
-So if you're using such a program, set the \fIprocInterrupts\fP resource
-to False.
-.TP 8
-.B Extensions
-If you are not making use of one of the server extensions (\fBXIDLE\fP,
-\fBSGI SCREEN_SAVER\fP, or \fBMIT-SCREEN-SAVER\fP), then it is possible, in 
-rare situations, for \fIxscreensaver\fP to interfere with event propagation 
-and make another X program malfunction.  For this to occur, that other
-application would need to \fInot\fP select \fBKeyPress\fP events on its 
-non-leaf windows within the first 30 seconds of their existence, but then 
-select for them later.  In this case, that client \fImight\fP fail to receive 
-those events.  This isn't very likely, since programs generally select a
-constant set of events immediately after creating their windows and then 
-don't change them, but this is the reason that it's a good idea to install 
-and use one of the server extensions instead, to work around this shortcoming
-in the X protocol.
-
-In all these years, I've not heard of even a single case of this happening,
-but it is theoretically possible, so I'm mentioning it for completeness...
-.TP 8
-.B Red Hot Lava
-There need to be a lot more graphics hacks.  In particular, there should be
-a simulation of a Lavalite (tm).
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number, and to inform the sub-programs

+Subject: screenblank and xautolock living in harmony
+Organization: The Duck Pond public unix: +1 408 249 9630, log in as 'guest'.
+Date: 23 Apr 1993 19:26:57 UTC
+
+
+I have a Sun and use xinit to start X. This presented a problem.
+If I use xautolock or xscreensaver to save the screen, then after
+a period of inactivity screenblank would turn the video off despite
+'xset s off'. If I didn't run screenblank, then who would take care of
+the display when X wasn't running?
+
+The hack that saved the day was to include this in .xinitrc:
+
+(
+
+while true ; do
+sleep 360
+touch /dev/console
+done
+
+) &
+killblank=$!
+
+[start up all the clients, etc, etc. Wait for the window manager
+to die, then ]
+
+kill $killblank
+
+The result is that screenblank is kept safely out of the way when X
+is running and left to do its job otherwise.
+
+Yes, I know using XDM would solve this problem.
+
+No, I'm probably not the first to think of this.
+
+You're welcome.

+# utils/Makefile.in --- xscreensaver, Copyright (c) 1997 Jamie Zawinski.
+# the `../configure' script generates `utils/Makefile' from this file.
+
+
+# The utilities in this directory are used mostly by the demos in ../hacks/.
+# The Makefile in that directory builds executables by simply referencing
+# the .o files in this directory.
+
+
+##############################################################################
+#
+# Some rambling about dynamic libraries follows, ignore it if you don't care
+# (which is almost assuredly the case.)
+#
+#
+# It would probably be sensible to just build a single .a file in this
+# directory, and link the hacks against that (statically.)  I haven't done
+# that for two reasons: first, it works now, and why fix what ain't broke;
+# second, it wouldn't actually improve anything for the end user (it would
+# just make the Makefiles be a little smaller.)
+#
+# People sometimes suggest that the stuff in this directory should be in a
+# dynamic library, and that the hacks should be linked dynamically against
+# it.  I haven't done this for a number of reasons:
+#
+#  *  First, the only thing that would improve would be disk space, in that
+#     the executable files themselves would be smaller.  That's it.  Many other
+#     things would get worse if we used a dynamic library:
+#
+#  *  Complication of installation procedures: suddenly, before any of the
+#     hacks will work, you need to have a dynamic library installed, and
+#     the system configured to use it.  This is, basically, rocket science.
+#     Most people don't know how to do this, it's a huge pain, and on many
+#     systems, it requires root access.
+#
+#  *  Complication of the Makefile: every system builds dynamic libraries
+#     differently.  Every compiler takes different flags.  I don't want to
+#     do the hand-holding for the scores of Unix systems and compilers on 
+#     which people try to build this program.
+#
+#  *  Reduction of maintainability: gdb is remarkably bad at dealing with
+#     debug info in dynamic libraries, and when debugging a hack, one would
+#     constantly be fighting the linker and the debugger (or linking
+#     statically when debugging.)
+#
+#  *  Version skew: when things are statically linked, it's perfectly ok to
+#     make incompatible changes to the APIs defined in this directory, so long
+#     as the current version in ../hacks/ is in sync.  Much more care would 
+#     need to be taken with such things if dynamic libraries were involved,
+#     to make sure that the major and minor versions of the library changed
+#     at the appropriate time.  This isn't too hard, but it's more work, and
+#     yet another opportunity to screw up.
+#
+#  *  Runtime memory usage goes *up*.  That's right, up!  When a program
+#     links in a dynamic library, the whole library is brought into the 
+#     address space, not just the files that are actually used.  Normally,
+#     this is ok, because if several programs are using (for example)
+#     libX11.so, chances are that the savings outweighs the overhead.  But
+#     the nature of xscreensaver is that only one of the hacks ever runs at
+#     a time -- so there would never be a second program using the utils/
+#     dynamic library with which things could be shared.
+#
+#  *  Runtime speed decreases slightly, since dynamic code is marginally
+#     slower.  On modern machines, this probably doesn't make a perceptible
+#     difference, however.
+#
+# So basically, I just don't think using libraries would be a win, and it would
+# definitely cause more of a maintenance and portability headache.  However,
+# if someone else wants to do the work to make it be an option to configure,
+# and verifies that it works on several (more than three) different Unixes,
+# I'd be happy to take the patches.

+/* If the server's root window contains a SERVER_OVERLAY_VISUALS property,
+   then that identifies the visuals which correspond to the video hardware's
+   overlay planes.  Windows created in these kinds of visuals have the
+   property that one particular pixel value is transparent.
+
+   On my Indy, there are two transparent visuals, one of which is at layer 1,
+   and one of which is at layer 2.  This is apparently the ordering in which
+   they are overlayed (1 being topmost.)  The other difference between them
+   is that the topmost one only has 2 planes, while the next one has 8.
+
+   Rumor has it that SGI, HP, DEC, and IBM all use the same mechanism.
+   Does Sun?
+
+   This code selects the topmost one, regardless of depth.  Maybe that's not
+   the right thing.  Well, in XScreenSaver, we only need to allocate two
+   colors from it (it's only used to display the stderr output, so that the
+   text can overlay the graphics without being obliterated by it.)
+

+/* This file contains code for grabbing a frame from one of the video inputs
+   on an SGI.  It returns it on a Drawable where it can be hacked at will.
+   This code checks all available video devices for the first one with a
+   non-blank signal.
+
+   It checks the deviced whose number comes from the `videoDevice' resource
+   first, then the default video device, then all the devices in order.
+
+   The intensity of the video signal is increased by the value of the
+   `videoGain' resource (a float) defaulting to 2.2, since NTSC video tends
+   to appear kind of dim on computer screens.
+
+   The video image is expanded to fit the window (while preserving the aspect
+   ratio.)  This is done by simply replicating pixels, not dithering.  That
+   turns out to look good enough most of the time.
+
+   If the target window is not TrueColor, the grabbed image will be quantized
+   to fit.  This also is done without dithering, but in this case, dithering
+   would help a lot, because it looks like crap.  So use TrueColor if you care.

+/* This file contains code for picking the best visual for GL programs by
+   actually asking the GL library to figure it out for us.  The code in
+   visual.c might do a good job of this on most systems, but not, in
+   particular, on SGIs.
+
+   Why?  Because with the SGI O2 X server is weird.
+
+   GL programs tend to work best on a visual that is *half* as deep as the
+   depth of the screen, since that way, they can do double-buffering.  So
+   generally, if the screen is 24 bits deep, but a 12-bit TrueColor visual
+   is available, then that's the visual you should use.
+
+   But on the server that runs on the O2 (a machine that has serious hardware
+   support for GL) the 12-bit PseudoColor visual looks awful (you get a black
+   and white, flickery image.)  On these machines, the visual you want turns
+   out to be 0x31 -- this is but one of the eight 15-bit TrueColor visuals
+   (yes, 8, and yes, 15) that O2s provide.  This is the only visual that works
+   properly -- as far as `xdpyinfo' is concerned, all of the 15-bit TrueColor
+   visuals are identical, but some flicker like mad, and some have deeply
+   weird artifacts (hidden surfaces show through!)  I suppose these other
+   visuals must be tied to some arcane hardware feature...
+
+   So the bottom line is, there exists information about visuals which is

+ * vroot.h -- Virtual Root Window handling header file
+ *
+ * This header file redefines the X11 macros RootWindow and DefaultRootWindow,
+ * making them look for a virtual root window as provided by certain `virtual'
+ * window managers like swm and tvtwm. If none is found, the ordinary root
+ * window is returned, thus retaining backward compatibility with standard
+ * window managers.
+ * The function implementing the virtual root lookup remembers the result of
+ * its last invocation to avoid overhead in the case of repeated calls
+ * on the same display and screen arguments. 
+ * The lookup code itself is taken from Tom LaStrange's ssetroot program.
+ *
+ * Most simple root window changing X programs can be converted to using
+ * virtual roots by just including
+ *
+ * #include <X11/vroot.h>
+ *
+ * after all the X11 header files.  It has been tested on such popular
+ * X clients as xphoon, xfroot, xloadimage, and xaqua.
+ * It also works with the core clients xprop, xwininfo, xwd, and editres
+ * (and is necessary to get those clients working under tvtwm).
+ * It does NOT work with xsetroot; get the xsetroot replacement included in
+ * the tvtwm distribution instead.
+ *
+ * Andreas Stolcke <stolcke@ICSI.Berkeley.EDU>, 9/7/90

+/* yarandom.c -- Yet Another Random Number Generator.
+
+   The unportable mess that is rand(), random(), drand48() and friends led me
+   to ask Phil Karlton <karlton@netscape.com> what the Right Thing to Do was.
+   He responded with this.  It is non-cryptographically secure, reasonably
+   random (more so than anything that is in any C library), and very fast.
+
+   I don't understand how it works at all, but he says "look at Knuth,
+   Vol. 2 (original edition), page 26, Algorithm A.  In this case n=55,
+   k=20 and m=2^32."
+
+   So there you have it.
+
+   ---------------------------
+   Note: xlockmore 4.03a10 uses this very simple RNG:
+
+       if ((seed = seed % 44488 * 48271 - seed / 44488 * 3399) < 0)
+         seed += 2147483647;
+       return seed-1;
+
+   of which it says
+
+       ``Dr. Park's algorithm published in the Oct. '88 ACM  "Random Number
+         Generators: Good Ones Are Hard To Find" His version available at
+         ftp://cs.wm.edu/pub/rngs.tar Present form by many authors.''
+
+   Karlton says: ``the usual problem with that kind of RNG turns out to
+   be unexepected short cycles for some word lengths.''
+
+   Karlton's RNG is faster, since it does three adds and two stores, while the
+   xlockmore RNG does two multiplies, two divides, three adds, and one store.
+
+   Compiler optimizations make a big difference here:
+       gcc -O:     difference is 1.2x.
+       gcc -O2:    difference is 1.4x.
+       gcc -O3:    difference is 1.5x.
+       SGI cc -O:  difference is 2.4x.
+       SGI cc -O2: difference is 2.4x.
+       SGI cc -O3: difference is 5.1x.
