+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.

+
+ XScreenSaver
+
+ a screen saver and locker for the X window system
+ by Jamie Zawinski
+
+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 --includedir=/opt/Motif/include --libdir=/opt/Motif/lib
+
+To build on VMS, see README.VMS.
+
+ ============
+
+The xscreensaver 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.
+
+The purpose of xscreensaver is to display pretty pictures on your screen
+when it is not in use, in keeping with the philosophy that unattended
+monitors should always be doing something interesting, just like they do
+in the movies.
+
+However, xscreensaver can also be used as a screen locker, to prevent
+others from using your terminal while your are away.
+
+The benefit that this program has over the combination of the xlock and
+xautolock programs is the ease with which new graphics hacks can be
+installed: you don't need to recompile this program to add a new display
+mode, you just change some resource settings. Any program which can be
+invoked in such a way that it draws on the root window of the screen can
+now be used as a screensaver without modification. The programs that
+are being run as screensavers don't need to have any special knowledge
+about what it means to be a screensaver.
+
+The XIDLE, MIT-SCREEN-SAVER, and/or SGI SCREEN_SAVER server extensions
+will be used if you have them.
+
+The dialog boxes (for locking and demo-mode) look best using Motif, but
+can be configured to use Athena widgets instead.
+
+Also included are several graphics hacks for use as screensavers. There's
+nothing magic about these: they're just programs that draw on the root
+window, which are pointed at by the screensaver's default resource settings.
+
+ qix - My own implementation of this, with many more options
+ than you would have thought qix could have.
+ helix - Generates spirally "stringart" patterns.
+ pedal - Draws a different kind of spirally pattern.
+ rorschach - Random inkblot patterns.
+ attraction - A bouncing ball demo, or a qix-like demo, or a wild
+ color-cycling thing, with some odd rules.
+ greynetic - Random colored/stippled rectangles.
+ rocks - Flying through an asteroid field.
+ blitspin - Rotate a bitmap using bitblts.
+ imsmap - Generates random maps or cloud formations.
+ hypercube - 2d projection of a hypercube rotating on all four axes.
+ slidescreen - Divides the screen into a grid and plays a 16-puzzle on it.
+ decayscreen - A melting effect.
+ halo - Random circular patterns.
+ pyro - Fireworks. Looks a lot like the version in xlock.
+ hopalong - Fractals. I snarfed this code from xlock.
+ flame - Fractals. Also from xlock.
+ noseguy - A guy with a big nose wanders around the screen saying
+ things. I snarfed this code from xnlock.
+ maze - This is the X maze demo modified to take a -root option
+ so that it works with xscreensaver.
+ lmorph - morphing line drawings.
+ bubbles - condensation forms on your monitor, then pops.
+ deco - Generates Brady-Bunch-era wall paneling.
+ moire - Circular interference patterns.
+ kaleidescope - Groovy, man.
+ swirl - Swirly color-cycling patterns.
+ bouboule - Spinning bubbles on a transparent ball.
+ braid - Draws random color-cycling braids around a circle.
+ drift - Drifting recursive fractal cosmic flames.
+ fract - Small, curvy geometric patterns.
+ galaxy - Spinning, colliding galaxies.
+ grav - Orbital simulation and/or cloud chamber.
+ ifs - Spinning, colliding iterated-function-system shapes.
+ julia - Animated rendition of the Julia set.
+ laser - Moving radiating lines.
+ lightning - Crackling fractal lightning bolts.
+ penrose - Quasiperiodic tilings.
+ sierpinski - two-dimensional Sierpinski triangle.
+ slip - Sucks your desktop through a jet engine.
+ spiral - Circular color-cycling interference patterns.
+ strange - Animating strange attractors.
+ flag - A waving flag of an arbitrary bitmap or text.
+ sphere - draw a bunch of shaded spheres.
+ forest - grows a fractal forest.
+ lisa - draws animated full-loop lisajous figures.
+ goop - Squishy transparent oil-and-bubble images
+ starfish - Radially-symmetric throbbing colormap-hacking blobs.
+ munch - The classic 1962-vintage "munching squares" hack.
+ rd-bomb - Reaction-diffusion fractals.
+ coral - Simulation of coral growth, sort of.
+ fadeplot - Draws a swimming ribbon.
+ escher - Draws some escher-like scenes (GLX only.)
+ gears - Draws interlocking rotating gears (GLX only.)
+ morph3d - Draws shiny shape-changing 3d forms (GLX only.)
+ superquadrics - More shiny shape-changing 3d forms (GLX only.)
+ pipes - Generates a field of intertwined plumbing (GLX only.)
+ rubik - Solves a Rubik's Cube (GLX only.)
+ sproingies - Marble Madness meets Q-Bert (GLX only.)
+
+All of these will pop up their own window unless given that -root option.
+See their man pages for more details.
+
+Other reasonable things to use as screensavers, if you have them, are
+
+ xdaliclock -root -builtin2 - melting digital clock
+ xswarm -r 2>&- - swimming sperm
+ xwave -root - random 3d graphs
+ xbouncebits - bounce arbitrary bitmaps around
+ ico -r -p8 -faces -sleep 1 - it's dull, but it's there
+ xv -root file.gif -quit - they don't all have to animate!
+ xsplinefun - bouncing splines
+ xfishtank -c black -d -r 1 - fish (use version 2.0 or later)
+ xtacy -root - various eye candy
+ /usr/demos/bin/bongo -wbongo - an SGI GL demo
+
+You can get all of these from the contrib directory on ftp.x.org. If you
+know of (or write) any other interesting programs that can be used as
+screensavers, please let me know!

+OpenVMS port of Xscreensavser version 2.05 July 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.
+
+VMS .HLP files are provied for all programms of this distribution.
+
+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,

+
+The easiest way to do this is to just tell the front panel to run
+something else when you click the lock symbol, switch off the "standard"
+screen blank/lock, and then start your own in sessionetc.
+
+Anyway, once you have a screensaver that you want to run instead, you'll
+need to add 2 files to ~/.dt/types/, one line to add to
+~/.dt/sessions/sessionetc and a change to make to the Style Manager.
+
+The two files are to change the behaviour of the Lock button in the middle
+of the front panel. To change the command run, edit the EXEC_STRING in
+the .dt file:

+
+And the Style Manager change is obvious - switch off the CDE blank and
+lock.
+
+You now have a screensaver and lock program that runs when you log in,
+blanks your screen after 3 minutes, locks it after 20, and cycles through
+a list of nice graphics every 2. I've also set the resources on mine to
+nicely fade in and out, rather than harsh cuts. The really brilliant
+thing about xscreensaver is that you can plug in *any* screen-filling
+graphics program - xscreensaver handles the blanking and locking, and
+controls the running of the graphics. The programs it runs and their
+arguements are controlled from the resource file, which comes with it and
+needs to be put in /usr/openwin/lib/app-defaults/.
+
+Clicking the "lock" in the front panel puts it straight into lock mode.
+
+Hope that's enough to get you going.

+ *
+ * The SCREEN_SAVER extension is found (as far as I know) only in the SGI

+ instead of putting them in bindir itself. You can
+ specify the name of the subdirectory. For example,
+ --exec-prefix=/usr/local/bin --enable-subdir=demos
+ would put xscreensaver in /usr/local/bin/, and would
+ put the demos in /usr/local/bin/demos/. Note that if
+ you do this, you must make sure that the directory
+ is on your \$PATH before xscreensaver is started: the
+ directory name is not hardcoded into the program.
+ This merely sets the default installation location.
+
+ --disable-subdir Just put the demos in \`bindir' (this is the default.)

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

+!
+*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.
+!
+! But, 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:".)
+!
+! All programs must be launched in such a way that they draw on the root

+
+! A few of the hacks require OpenGL, and will only be built if you have it.
+! Note that those hacks (gears, superquadratics, escher, pipes, and
+! sproingies) will work best on a visual *half* as deep as the depth of the
+! screen, since that way they can do double-buffering -- on an SGI, you
+! should specify the 12-bit TrueColor visual (probably 0x29) instead of
+! letting XScreenSaver pick the visual itself (specifying "TrueColor" would
+! select the 24-bit TrueColor visual, and double-buffering wouldn't be used,
+! resulting in flicker.)
+!
+! Some other programs that you might want to track down (these work as
+! XScreenSaver helpers, but are not distributed with it):
+!
+! xdaliclock -root -builtin2 \n\
+! xswarm -r 2>&- \n\
+! xwave -root \n\
+! xbouncebits ... \n\
+! ico -r -faces -sleep 1 -obj ico \n\
+! xsplinefun \n\
+! kaleid -root \n\
+! color: xfishtank -c black -d -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 slideshow of images, you can do something like this:
+!
+! default: xv -root -rmode 5 image-1.gif -quit
+! default: xv -root -rmode 5 image-2.gif -quit
+! default: xv -root -rmode 5 image-3.gif -quit
+! ...and so on...
+!
+! however, for this to work, you must also have started the screensaver so
+! that it uses the default colormap (the "-no-install" command-line option, or
+! the "installColormap: False" resource) because when XV is running in "-root"
+! mode, it always assumes that the default colormap is being used, rather than
+! examining the window it is drawing on to see what colormap it has. (It
+! also assumes the default visual, but we've taken care of that above.)
+!
+! Some SGI GL programs work with XScreenSaver; most don't.
+!
+! Bongo works fine:
+!
+! /usr/demos/bin/bongo -wbongo
+!
+! ElectroPaint sort-of works; XScreenSaver will launch it, and it will run
+! properly, but when it's time to turn off the screensaver, you need to hit
+! the Escape key, rather than just moving the mouse. Apparently GL programs
+! are able to intercept the keyboard even when X has the keyboard grabbed!
+!
+! /usr/demos/bin/ep
+!
+! None of the other SGI GL demos I've tried worked, because none of them seem
+! to have command-line options that will make them take up the whole screen;
+! so all you get is a miniscule 100x100 image, which is worthless. This is a
+! shame, since many of those demos would make fine screensavers.
+!
+! If anyone who understands how "haven" works would like to send me the code
+! necessary to do what it does, I would be much obliged.

+ currently-focussed button is as well! Morons! Villains! Shitheads!

+ - 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
+ portable.)

+.SH NAME
+xscreensaver-command - control a running xscreensaver process
+.SH SYNOPSIS
+.B xscreensaver-command
+[\-help] [\-demo] [\-activate] [\-deactivate] [\-lock] [\-cycle] [\-next] [\-prev] [\-exit] [\-restart] [\-version] [\-time]
+.SH DESCRIPTION
+The \fIxscreensaver\-command\fP program controls a running \fIxscreensaver\fP
+process by sending it client-messages.
+.SH OPTIONS
+.I xscreensaver-command
+accepts the following options:
+.TP 8
+.B \-help
+Prints a brief summary of command-line options.
+.TP 8
+.B \-demo
+Cause the screensaver to enter its interactive demo mode, in which one
+can experiment with the various graphics hacks available. See
+.BR xscreensaver (1)
+for details.
+.TP 8
+.B \-activate
+Tell the screensaver to turn on immediately (that is, pretend that the
+user been idle for long enough.) It will turn off 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 remove your hand from the mouse before
+the screensaver comes on.
+.TP 8
+.B \-deactivate
+Tell the screensaver to turn off, as if there had been user activity.
+If locking is enabled, then the screensaver will prompt for a password
+as usual.
+.TP 8
+.B \-lock
+Like \fI\-activate\fP, but a password will be required before the screensaver
+turns off, even if the screensaver's \fIlock\fP resource is false. The
+display will be locked immediately even if the screensaver's \fIlockTimeout\fP
+resource is non-zero.
+.TP 8
+.B \-cycle
+Tell the screensaver to change which graphics hack it is running, just
+as if the ``cycle'' timer had expired. A new hack will be 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 screenhack that will be run is the next
+one in the list of programs, instead of a randomly-chosen one. Repeatedly
+executing this will cycle through each hack in turn (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 \-exit
+Causes the screensaver process to exit gracefully. This is a safer and
+easier way to kill the screensaver than by using \fIkill\fP.
+
+.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 \-restart
+Causes the screensaver process to exit and then restart with the same command
+line arguments. This is a good way of causing the screensaver to re-read the
+resource database.
+
+If the screensaver is run from \fIxdm(1)\fP (that is, it is already running
+before you log in) then you may want to issue the ``restart'' command from
+one of your startup scripts, so that the screensaver gets your resource
+settings instead of the default ones.
+.TP 8
+.B \-version
+Print (on stdout) the version number of the xscreensaver program that is
+running on $DISPLAY. (To see the version number of \fIxscreensaver-command\fP
+itself, use the \fI\-help\fP option.)
+.TP 8
+.B \-time
+This option prints on stdout the time at which the screensaver last activated
+(blanked the screen) or deactivated (restored the screen.) Note that the
+activation-time is not the last time at which the user was active, but is
+some time later (it is the time at which either: xscreensaver decided that
+the user has been idle long enough; or, the user explicitly activated the
+screensaver or locker.)
+.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 "SEE ALSO"
+.BR X (1),
+.BR xscreensaver (1)
+.SH BUGS
+Some diagnostics are reported on the stderr of the \fIxscreensaver\fP
+process, not this process, so the caller of \fIxscreensaver-command\fP
+may not see the error messages.

+/* ========================================================================
+ * 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 -DDEBUG.
+ * - 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 NAME
+xscreensaver - graphics hack and screen locker, launched when the user is idle
+.SH SYNOPSIS
+.B xscreensaver
+[\-display \fIhost:display.screen\fP] [\-timeout \fIint\fP] [\-cycle \fIint\fP] [\-nice \fIint\fP] [\-lock] [\-no\-lock] [\-lock\-timeout \fIint\fP] [\-demo] [\-visual \fIvisual\fP] [\-install] [\-no\-install] [\-verbose] [\-silent] [\-xidle\-extension] [\-no\-xidle\-extension] [\-sgi\-extension] [\-no\-sgi\-extension] [\-mit\-extension] [\-no\-mit\-extension] [\-xrm \fIresources\fP]
+.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 OPTIONS
+.I xscreensaver
+accepts the following command line options:
+.TP 8
+.B \-timeout \fIminutes\fP
+The screensaver will activate after the keyboard and mouse have been idle
+for this many minutes. Default 10.
+.TP 8
+.B \-cycle \fIminutes\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 not be changed:
+only one demo will run until the screensaver is deactivated by user activity.
+Default 10.
+.TP 8
+.B \-nice \fIinteger\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 20.
+
+(Higher numbers mean lower priority; see
+.BR nice (1)
+for details.)
+.TP 8
+.B \-lock
+Enable locking: before the screensaver will turn off, it requires you to
+type the password of the person who launched the screensaver, or the root
+password. (Note: 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.)
+.TP 8
+.B \-no\-lock
+Disable locking. This is the default.
+.TP 8
+.B \-lock\-timeout \fIminutes\fP
+This is how long after the screensaver activates that locking is enabled.
+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. But, if there was user activity at 15 minutes or later
+(\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 screensaver activates.
+.TP 8
+.B \-demo
+Enter the interactive demo mode immediately after startup. Normally
+demo mode is invoked via the
+.BR xscreensaver\-command (1)
+program, but this is a shortcut for new users. See below for a description
+of how demo-mode works.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which X visual to use by default. Legal values 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.
+.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
+.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
+.PP
+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 \-install
+When using a non-default visual, 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.)
+.TP 8
+.B \-no\-install
+Use the default colormap.
+.TP 8
+.B \-verbose
+Print diagnostics.
+.TP 8
+.B \-silent
+
+.TP 8
+.B \-xidle\-extension
+Use the \fBXIDLE\fP server extension to decide whether the user is idle.
+This is the default if \fIxscreensaver\fP has been compiled with support
+for this extension. On X11R4 or X11R5 systems, the XIdle method is faster
+and more reliable than what will be done otherwise, so use it if you can.
+.TP 8
+.B \-no\-xidle\-extension
+Don't use the \fBXIDLE\fP server extension.
+.TP 8
+.B \-sgi\-extension
+Use the SGI \fBSCREEN_SAVER\fP server extension 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.
+.TP 8
+.B \-no\-sgi\-extension
+Don't use the SGI \fBSCREEN_SAVER\fP server extension.
+.TP 8
+.B \-mit\-extension
+Use the \fBMIT\-SCREEN\-SAVER\fP server extension to decide whether the user
+is idle. This is the default if \fIxscreensaver\fP has been compiled with
+support for this extension. However, this extension is flaky, so it's use
+is not really recommended. (It also makes the \fIfade\fP option not work
+properly.)
+.TP 8
+.B \-no\-mit\-extension
+Don't use the \fBMIT\-SCREEN\-SAVER\fP server extension.
+.SH X RESOURCES
+\fIxscreensaver\fP understands the following resources:
+.PP
+.TP 8
+.B timeout \fR(class \fBTime\fP)

+.TP 8
+.B cycle \fR(class \fBTime\fP)
+Same as the \fI\-cycle\fP command-line option. Default 10 minutes.
+.TP 8
+.B nice \fR(class \fBNice\fP)

+Same as the \fI\-lock\-timeout\fP command-line option.
+.TP 8
+.B passwdTimeout \fR(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.) 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 verbose \fR(class \fBBoolean\fP)
+Same as the \fI\-verbose\fP command-line option.
+.TP 8
+.B xidle \fR(class \fBBoolean\fP)
+Same as the \fI\-xidle\fP command-line option.
+.TP 8
+.B fade \fR(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. Default true. A fade will also be done when
+switching graphics hacks (when the \fIcycle\fP timer expires.)
+.TP 8
+.B unfade \fR(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 \fR(class \fBTime\fP)
+If \fIfade\fP is true, this is how long the fade will be in
+seconds (default 3.)
+.TP 8
+.B fadeTicks \fR(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.

+.B visualID \fR(class \fBVisualID\fP)
+Same as the \fI\-visual\fP command-line option. Default \fBdefault\fP.
+.TP 8
+.B installColormap \fR(class \fBBoolean\fP)
+Same as the \fI\-install\fP command-line option. Default true.
+.TP 8
+.B captureStderr \fR(class \fBBoolean\fP)
+Whether \fIxscreensaver\fP should redirect its standard-error stream to the
+window itself. Since its nature is to take over the screen, you would not
+normally see error messages generated by the screensaver or the programs it
+runs; this resource will cause the output of all relevant programs to be
+drawn on the screensaver window itself instead of written to the controlling
+terminal of the screensaver driver process. Default true.
+.TP 8
+.B captureStdout \fR(class \fBBoolean\fP)
+Like \fBcaptureStderr\fP but for the standard-output stream. Default true.
+.TP 8
+.B font \fR(class \fBFont\fP)
+The font used for the stdout/stderr text, if \fBcaptureStdout\fP or
+\fBcaptureStderr\fP are true. Default \fB*\-medium\-r\-*\-140\-*\-m\-*\fP
+(a 14 point fixed-width font.)
+.TP 8
+.B textForeground \fR(class \fBForeground\fP)
+The foreground color used for the stdout/stderr text, if \fBcaptureStdout\fP
+or \fBcaptureStderr\fP are true. Default: Yellow.
+.TP 8
+.B textBackground \fR(class \fBBackground\fP)
+The background color used for the stdout/stderr text, if \fBcaptureStdout\fP
+or \fBcaptureStderr\fP are true. Default: Black.
+.TP 8
+.B programs \fR(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.
+
+Note that you must escape the newlines; here is an example of how you
+might set this in your \fI.Xdefaults\fP file:
+
+.EX
+xscreensaver.programs: \\
+ qix -root \\n\\
+ ico -r -faces -sleep 1 -obj ico \\n\\
+ xdaliclock -builtin2 -root \\n\\
+ xv -root -rmode 5 image.gif -quit \\n
+.EE
+.RS 8
+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 \fItvtwm\fP. (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 accomidated:
+
+.EX
+ PseudoColor: cmap-program -root \\n\\
+ TrueColor: 24bit-program -root \\n\\
+.EE
+.RE
+.RS 8
+(This sort of thing used to be accomplished with the \fIcolorPrograms\fP
+and \fImonoPrograms\fP resources, but those resources have now been removed;
+a warning will be issued if they are used.)
+
+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.
+.RE
+.PP
+.PP
+Normally you won't need to change the following resources:
+.TP 8
+.B bourneShell \fR(class \fBBourneShell\fP)
+The pathname of the shell that \fIxscreensaver\fP uses to start subprocesses.
+This must be whatever your local variant of \fB/bin/sh\fP is -- in particular,
+it must not be \fBcsh\fP.
+.TP 8
+.B windowCreationTimeout \fR(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 pointerPollTime \fR(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 initialDelay \fR(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 30 seconds.
+.TP 8
+.B overlayStderr \fR(class \fBBoolean\fP)
+If \fBcaptureStderr\fP or \fBcaptureStdout\fP are 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.)
+.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. The window or windows is given the
+appropriate properties so 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 USING XDM(1)
+You can run \fIxscreensaver\fP from your xdm session, so that the
+screensaver will run even when nobody is logged in on the console.
+Simply add \fB"xscreensaver &"\fP to your \fI/usr/lib/X11/xdm/Xsetup\fP
+file. Because \fIxdm\fP grabs the keyboard, keypresses will not make
+the screensaver deactivate, but any mouse activity will.
+
+(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 \fIxdm-config\fP file. See the man page for
+.BR xdm (1)
+for more details.)
+
+Users may want to add \fB"xscreensaver-command -restart"\fP to their
+startup scripts, so that the screensaver will be reinitialized with
+their private resource settings when they log in.
+
+It is safe to run this program 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.
+
+Locking doesn't work if the screensaver is launched by \fIxdm\fP. To get
+around this, you can run the screensaver from \fIxdm\fP without locking,
+and kill and restart it from your personal X startup script to enable
+locking; for example:
+
+.EX
+ xscreensaver-command -exit ; xscreensaver
+.EE
+.SH DEMO MODE
+If \fIxscreensaver\fP receives the \fBDEMO\fP ClientMessage, which is done
+by running the \fBxscreensaver\-command\fP program with the \fB\-demo\fP
+option, the screensaver will black the screen and pop up a dialog box from
+which you can examine and experiment with the client programs.
+
+The 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. Clicking
+the mouse again will bring the dialog box back.
+
+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. (Note that these are
+one-time changes and won't be remembered; to make the changes permanent,
+you need to edit your X resource file.)
+
+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 scroll around to the top when it reaches
+the bottom.
+.TP 8
+.B Run Previous
+Opposite of Run Next; at the top, it scrolls around to the bottom.
+.TP 8
+.B Edit Parameters
+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. Changing
+these parameters here will affect only the running \fIxscreensaver\fP
+process; to make the changes permanent, you need to edit your X resource
+file.
+.TP 8
+.B Exit Demo Mode
+Returns to normal screensaver operation.
+.TP 8
+.B Reinitialize
+This causes the X resource database to be re-read, to pick up any changes
+you might have made. This works by causing the screensaver process to exit
+and then restart itself with the same command-line arguments. This is just
+like the \fI\-restart\fP argument to
+.BR xscreensaver\-command (1)
+except that when executed from this button, the screensaver will
+automatically return to demo mode after restarting.
+.SH BUGS
+(This is not a bug, but) note that as of release 1.32, the \fBcolorPrograms\fP
+and \fBmonoPrograms\fP resources are no longer used: they have been
+supplanted by the extended syntax of the \fBprograms\fP resource (see above.)
+.TP 8
+Extensions
+If you are not making use of one of the server extensions (\fBXIDLE\fP,
+\fBSCREEN_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.
+.TP 8
+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.)
+
+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
+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
+Locking and XDM
+Locking doesn't work if the screensaver is launched by \fIxdm\fP.
+The reason for this is that when it is launched by \fIxdm\fP, the
+screensaver process is owned by some standard user id (such as \fIroot\fP
+or \fIdaemon\fP) instead of the user who is logged in on the console:
+because the screensaver was started \fIbefore\fP anyone was logged in.
+In order for the screensaver to prompt for the password of the person
+who had logged in from \fIxdm\fP, it would need to know who that user was,
+and there is no reliable and safe way to figure that out. (And even if
+there was, there would be some other security issues here as well.)
+
+So if you want to use it as a locker, you must start it with your user id.
+If it has already been started by \fIxdm\fP, you can kill it with
+\fBxscreensaver-command -exit\fP, and then start it again as you.
+.TP 8
+Passwords
+If you get an error message 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. 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 \fIgetpwent\fP interface; in that case, you may need to change
+some options in \fIconfig.h\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. This turns out to be kind of hard to fix. (But remember,
+kids! Unix security doesn't do much more than keep honest people honest...)
+.TP 8
+TWM and Colormaps
+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 seem to have this problem. The race condition exists
+because X apparently 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 the screensaver installs its colormap, \fBtwm\fP responds to
+the \fBColormapNotify\fP event that is generated 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. Any thoughts on this problem are welcome...
+.TP 8
+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.
+.TP 8
+MIT Extension and Fading
+When using the \fBMIT-SCREEN-SAVER\fP extension in conjunction with
+the \fBfade\fP option, you may 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.
+.TP 8
+LessTif (Motif Clone)
+Rumor has it that demo mode is buggy if XScreenSaver was compiled with the
+GNU LessTif reimplementation of Motif. Since it works fine with OSF Motif
+on a variety of systems, I assume these problems are due to bugs in LessTif.
+Again, any insight would be appreciated.
+.TP 8

+There need to be a lot more graphics hacks. In particular, there should be
+a simulation of a Lavalite (tm).

+/* 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.

+.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.
+.PP
+.TP 8
+.B \-delay microseconds
+How long to delay between steps of the rotation process, in microseconds.
+Default is 500000, one-half second.
+.PP
+.TP 8
+.B \-delay2 microseconds
+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 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 (petit@eurecom.fr, jpetit@essi.fr)
+ *
+ * Use: batchcount is the number of stars.
+ * cycles is the maximum size for a star
+ *
+ * 15-May-97: jwz@netscape.com: 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.

+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.
+.TP 8
+.B \-cycles \fIinteger\fP
+
+.TP 8
+.B \-count \fIinteger\fP
+
+.TP 8
+.B \-3d
+Do red/blue 3d separations (for 3d glasses.)
+
+.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
+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.

+ * 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.

+.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.

+.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.

+.SH NAME
+galaxy - draws spinning galaxies
+.SH SYNOPSIS
+.B galaxy
+[\-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] [\-size \fIinteger\fP] [\-trail] [\-no\-trail]
+
+.SH DESCRIPTION
+The \fIgalaxy\fP program draws spinning galaxies.
+.SH OPTIONS
+.I galaxy
+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
+
+.TP 8
+.B \-size \fIinteger\fP
+
+.TP 8
+.B \-trail
+.TP 8
+.B \-no\-trail
+
+.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.

+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.

+ * This mode shows some interesting scenes that are impossible OR very

+ * 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.

+ *
+ * Revision History:
+ * 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 Moebious 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).

+ * Marcelo F. Vianna (Jul-31-1997)
+ *
+ * Revision History:
+ * 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 a license
+ * at work...) There was not much to do since I could not exit
+ * from home... :)

+ * 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 ;)

+ 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...

+.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 only works
+on \fBPseudoColor\fP displays. 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 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.

+.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.

+ * Revision History:

+ * 10-May-97: jwz@netscape.com: ported from xlockmore 4.03a10 to be a

+ * (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 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.

+.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.

+.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

+.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

+.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.

+ * Revision History:
+ * 28-May-97: jwz@netscape.com: added interactive frobbing with the mouse.
+ * 10-May-97: jwz@netscape.com: 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.

+.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 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.

+ * Revision History:

+ *
+ * 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.

+.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 \-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 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 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.

+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

+ * 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.

+[\-display \fIhost:display.screen\fP] [\-foreground \fIcolor\fP] [\-background \fIcolor\fP] [\-window] [\-root] [\-mono] [\-install] [\-visual \fIvisual\fP] [\-ncolors \fIinteger\fP] [\-delay \fImicroseconds\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.
+
+.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 \-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.

+.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 only works on \fBPseudoColor\fP displays. 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.

+.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.

+.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.

+.SH DESCRIPTION
+The \fIspiral\fP program draws moving circular spiral patterns
+.SH OPTIONS
+.I spiral
+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 \-count \fIinteger\fP
+Default 40.
+.TP 8
+.B \-cycles \fIinteger\fP
+Default 350.
+
+.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
+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.

+/*
+** 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.

+Newsgroups: alt.hackers
+From: mrapple@quack.kfu.com (Nick Sayer)
+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.

+ * 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.
+ *

+/* 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.
