+.SH DESCRIPTION
+The \fIboing\fP program draws a bouncing checkered ball on a grid.
+
+This is a clone of the first graphics demo for the Amiga 1000, which
+was written by Dale Luck and RJ Mical during a break at the 1984
+Consumer Electronics Show (or so the legend goes.) The boing ball was
+briefly the official logo of Amiga Inc., until they were bought by
+Commodore later that year.
+
+With no arguments, this program looks a lot like the original Amiga
+demo. With "-smooth -lighting", it looks... less old.

+.TP 8
+.B \-scanlines
+If the window is large enough, draw horizontal lines to simulate the
+scanlines on a low resolution monitor.
+.TP 8
+.B \-speed \fIratio\fP
+Change the animation speed; 0.5 to go half as fast, 2.0 to go twice as fast.
+.TP 8
+.B \-no\-spin
+Don't rotate the ball.
+.TP 8
+.B \-angle \fIdegrees\fP
+The jaunty angle at which the ball sits. Default 15 degrees.
+.TP 8

+.SH DESCRIPTION
+This program shows the view of an observer located inside a set of points
+arranged to a 3D lattice. As the lattice rotates, various view-throughs appear
+and evolve. A simple idea with interesting results.
+.SH OPTIONS
+.I cubicgrid
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long to pause between frames. Default is 20000, or 0.02 second.
+.TP 8
+.B \-mono
+Draw in black and white. If not used, a fixed all-color scheme is chosen.
+.TP 8
+.B \-speed \fInumber\fP
+The maximum speed of the rotation. The actual speed and axis change smoothly
+for better effect. 0.5 - 10. The default is 1.0.
+.TP 8
+.B \-zoom \fInumber\fP
+Size of the lattice. Ideally it should fill all the screen, but one may find
+other values also interesting. 5 - 50. The default of 20 should do for common
+screen aspect ratios.
+.TP 8
+.B \-ticks \fInumber\fP
+The count of points drawn along every axis. 10 - 100. The default is 30.
+.TP 8
+.B \-bigdots
+Draw the points twice as big.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH ENVIRONMENT

+.SH DESCRIPTION
+This program draws a box and a few line segments, and generates a
+radial blur outward from it. This creates flowing field effects.
+
+This is done by rendering the scene into a small texture, then
+repeatedly rendering increasingly-enlarged and increasingly-transparent
+versions of that texture onto the frame buffer. As such, it's quite
+graphics intensive: don't bother trying to run this if you don't have
+hardware-accelerated texture support. It will hurt your machine bad.

+Uses Craig Reynolds Boids algorithm to simulate a 3d school of

+of the algorithm and the original paper. This is a lightly modified
+version of the algorithm that supports goal attraction.
+
+Many different behaviors are possible by tweaking the parameters. No sanity checking is performed
+on the command line params, so if you want to use negative accelerations or minimum velocity that is
+larger than maximum velocity or that sort of thing, the simulation will try to digest it.

+.SH DESCRIPTION
+Loads a random sequence of images and smoothly scans and zooms around
+in each, fading from pan to pan.
+
+This program requires a good video card capable of supporting large
+textures.
+
+To specify the directory that images are loaded from, run
+.BR xscreensaver-demo (1)
+and click on the "Advanced" tab.
+.SH OPTIONS
+.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 \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-duration \fIseconds\fP
+How long each image will be displayed before loading a new one.
+Default 30 seconds.
+.TP 8
+.B \-pan \fIseconds\fP
+How long each pan-and-zoom should last. Default 6 seconds.
+
+With the default settings of \fI\-pan 6 \-duration 30\fP, each image
+will be displayed five times (30/6), and then a new image will be loaded.
+If you want a new image to be loaded at each fade, then set \fI\-pan\fP
+and \fI\-duration\fP to the same value.
+.TP 8
+.B \-fade \fIseconds\fP
+How long each cross-fade between images should last. Default 2 seconds.
+If set to 0, then no cross-fading will be done (all transitions
+will be jump-cuts.)
+
+Note that fades are included in the pan time, so \fI\-fade\fP cannot
+be larger than \fI\-pan\fP.
+.TP 8
+.B \-zoom \fInumber\fP
+Amount to zoom and pan as a percentage. Default: 75, meaning that
+75% or more of each image will always be visible. If set to 100%,
+then the images will always fill the screen, and no panning or
+zooming will occur. (Images will still smoothly fade from one
+to another if \fI\-fade\fP is non-zero.)
+.TP 8
+.B \-titles
+Whether to print the file name of the current image in the upper left corner.
+.TP 8
+.B \-letterbox
+In "letterbox" mode, when an image is not the same aspect ratio as the screen,
+black bars will appear at the top/bottom or left/right so that the whole
+image can be displayed. This is the default.
+.TP 8
+.B \-clip
+In "clip" mode, when an image is not the same aspect ratio as the screen,
+we will zoom in further until the image takes up the whole screen.
+This is the opposite of \fI\-letterbox\fP.
+.TP 8
+.B \-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000 (0.02 seconds.).
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.TP 8
+.B \-cutoff \fInumber\fP
+If the frame rate we are achieving is lower than this, then panning,
+fading, and zooming will be disabled. Default 5 FPS.
+
+The idea here is that if your machine can't maintain a decent frame
+rate, then it must not have fast 3D hardware, so we might as well
+behave in a simpler manner. Set this to 0 to disable this check.
+.TP 8
+.B \-debug
+Prints debugging info to stderr.
+.TP 8
+.B \-wireframe
+Another debug mode.

+The \fIgltext\fP program draws some text spinning around in 3D, using
+a font that appears to be made of solid tubes.
+.SH OPTIONS
+.I gltext
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-text \fIstring\fP
+The text to display. This may contain newlines, but it shouldn't be
+very long. The default is to display the machine name and OS version.
+
+This may also be a format string acceptable to
+.BR date (1)
+and
+.BR strftime (3) ,
+in which case, it will be updated once a second. So to make this
+program display a spinning digital clock, you could do this:
+.EX
+gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
+.EE
+To include a literal `%', you must double it: `%%'.
+
+See the man page for
+.BR strftime (3)
+for more details.
+.TP 8
+.B \-program \fIcommand\fP
+The given program is run, and its output is displayed.
+If specified, this overrides \fI\-text\fP.
+The program will be re-run every 5 seconds to re-generate the text.
+It should run quickly, and shouldn't generate too much text.
+.TP 8
+.B \-wander
+Move the text around the screen. This is the default.
+.TP 8
+.B \-no\-wander
+Keep the text centered on the screen.
+.TP 8
+.B \-spin
+Which axes around which the text should spin. The default is "XYZ",
+meaning rotate it freely in space. "\fB\-spin Z\fP" would rotate the
+text in the plane of the screen while not rotating it into or out
+of the screen; etc.
+.TP 8
+.B \-no\-spin
+Don't spin the text at all: the same as \fB\-spin ""\fP.
+.TP 8
+.B \-front
+When spinning, never spin all the way around or upside down:
+always face mostly forward so that the text is easily readable.
+.TP 8
+.B \-no\-front
+Allow spins to go all the way around or upside down. This is the default.
+.TP 8
+.B \-wireframe
+Render in wireframe instead of solid.

+.SH DESCRIPTION
+This draws the recursive Hilbert space-filling curve, in both 2D and
+3D variants. It incrementally animates the growth and recursion to
+the maximum depth, then unwinds it back.
+
+The Hilbert path is a single contiguous line that can fill a volume
+without crossing itself. As a data structure, Hilbert paths are
+useful because ordering along the curve preserves locality: points
+that close together along the curve are also close together in space.
+The converse is often, but not always, true. The coloration

+.SH DESCRIPTION
+The \fIhypertorus\fP program shows the Clifford torus as it rotates in
+4d. The Clifford torus is a torus lies on the "surface" of the
+hypersphere in 4d. The program projects the 4d torus to 3d using
+either a perspective or an orthographic projection. Of the two
+alternatives, the perspective projection looks much more appealing.
+In orthographic projections the torus degenerates into a doubly
+covered cylinder for some angles. The projected 3d torus can then be
+projected to the screen either perspectively or orthographically.
+There are three display modes for the torus: mesh (wireframe), solid,
+or transparent. Furthermore, the appearance of the torus can be as a
+solid object or as a set of see-through bands or see-through spirals.
+Finally, the colors with with the torus is drawn can be set to either
+two-sided or to a color wheel. In the first case, the torus is drawn
+with red on the outside and green on the inside. This mode enables
+you to see that the torus turns inside-out as it rotates in 4d. The
+second mode draws the torus with a fully saturated color wheel. This
+gives a very nice effect when combined with the see-through bands or
+see-through spirals mode. The rotation speed for each of the six
+planes around which the torus rotates can be chosen. This program is
+very much inspired by Thomas Banchoff's book "Beyond the Third
+Dimension: Geometry, Computer Graphics, and Higher Dimensions",
+Scientific American Library, 1990.

+the inside.
+.TP 8
+.B \-colorwheel
+Display the torus with a fully saturated color wheel (default). If
+the torus is displayed as see-through bands each band will be
+displayed with a different color. Likewise, if the torus is displayed
+as see-through spirals each spiral will receive a different color.
+.PP
+The following two options are mutually exclusive. They determine how
+the torus is projected from 3d to 2d (i.e., to the screen).

+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH INTERACTION
+If you run this program in standalone mode you can rotate the
+hypertorus by dragging the mouse while pressing the left mouse button.
+This rotates the hypertorus in 3D, i.e., around the wx, wy, and wz
+planes. If you press the shift key while dragging the mouse with the
+left button pressed the hypertorus is rotated in 4D, i.e., around the
+xy, xz, and yz planes. To examine the hypertorus at your leisure, it
+is best to set all speeds to 0. Otherwise, the hypertorus will rotate
+while the left mouse button is not pressed.

+Specify which visual to use. Legal values are the name of a visual class,

+Render in wireframe instead of solid. Default: render solid.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.TP 8
+.B -tetra | -no-tetra
+Whether to start the shape in the form of a tetrahedron. The default
+is to start as a sphere.
+.TP 8
+.B -color \fIcolorspec\fP
+Available options for colorspec are: cycle, flowerbox, clownpuke, chrome
+and #xxxxxx (i.e an (old-style) X color specification.) Default: cycle
+.TP 8
+.B -spooky \fIn\fP
+This option controls a kind of interesting effect obtained by
+using unnormalized normal vectors (how's that for an oxymoron?) in OpenGL.
+A value of zero disables the effect. Other values vary the lengths of
+the normals proportionally.
+Okay, so it's not very spooky. Sue me.
+Default: 0
+.TP 8
+.B -complexity \fIn\fP
+Valid options are 1, 2, and 3. Everything else is treated as though it
+were 2, which is the default. This controls the number of polygons in
+the 'thing'. A value of 1 yields 1024, and the values go up in powers
+of 4. (i.e. 4096, 16384.)
+ note: There is an inherent lack of stability
+at lower complexity, which can cause the shape to devolve into a 'flying
+snotrag'.
+.TP 8
+.B -speed \fIn\fP
+Controls how fast the blob moves around the screen. Default: 500.
+.TP 8
+.B -spherism, -hold, -distance, -damping
+These options control the 'jigglyness'. The best way to explain these is
+to explain how jigglypuff works. Basically, the shape is a tetrahedron
+whose faces are subdivided into a number of triangles, forming a mesh.
+Each of the vertices of the mesh has two different forces applied to it:
+one proportional to its distance from the surface of a sphere, and one
+proportional to the difference of the distance to each of its neighbors
+in the mesh to a given ideal distance. In short, one tries to move the
+points into the configuration of a sphere, and the other tries to push
+them back into a tetrahedron. The catch is that the points have inertia,
+so they always overshoot their target, and hence they oscillate. The
+magnitudes of the two forces is controlled by the options 'spherism' and
+\'hold'; 'distance' specifies the distance the vertices seek to keep from
+their neighbors, with 500 corresponding to the size of the start tetrahedron.
+e.g. if you were to give the options '-tetra -spherism 0 -distance 500', you
+would end up with a stable tetrahedron. The 'damping' option can help to
+keep the blob from collapsing or flying apart. The option specifies the
+speed at which damping starts, hence lower values mean more damping.
+Defaults: spherism: 75; hold: 800; distance: 100; damping: 500.
+.TP 8
+.B -random
+Probably the only parameter you'l ever need. Overrides almost all of the
+parameters with random values. The values affected are: speed, spherism,
+hold, distance, damping, spooky, color, wireframe and tetra.
+Default: off

+.SH DESCRIPTION
+The \fIkleinbottle\fP program shows two different Klein bottles in 4d:
+the figure-8 Klein bottle or the Lawson Klein bottle. You can walk on
+the Klein bottle, see it turn in 4d, or walk on it while it turns in
+4d. The figure-8 Klein bottle is well known in its 3d form. The 4d
+form used in this program is an extension of the 3d form to 4d that
+does not intersect itself in 4d (which can be seen in the depth colors
+mode). The Lawson Klein bottle, on the other hand, does intersect
+itself in 4d. Its primary use is that it has a nice appearance for
+walking and for turning in 3d. The Klein bottle is a non-orientable
+surface. To make this apparent, the two-sided color mode can be used.
+Alternatively, orientation markers (curling arrows) can be drawn as a
+texture map on the surface of the Klein bottle. While walking on the
+Klein bottle, you will notice that the orientation of the curling
+arrows changes (which it must because the Klein bottle is
+non-orientable). The program projects the 4d Klein bottle to 3d using
+either a perspective or an orthographic projection. Which of the two
+alternatives looks more appealing depends on the viewing mode and the
+Klein bottle. For example, the Lawson Klein bottle looks nicest when
+projected perspectively. The figure-8 Klein bottle, on the other
+hand, looks nicer while walking when projected orthographically from
+4d. The projected Klein bottle can then be projected to the screen
+either perspectively or orthographically. When using the walking
+modes, perspective projection to the screen should be used. There are
+three display modes for the Klein bottle: mesh (wireframe), solid, or
+transparent. Furthermore, the appearance of the Klein bottle can be
+as a solid object or as a set of see-through bands. Finally, the
+colors with with the Klein bottle is drawn can be set to two-sided,
+rainbow, or depth. In the first case, the Klein bottle is drawn with
+red on one "side" and green on the "other side". Of course, the Klein
+bottle only has one side, so the color jumps from red to green along a
+curve on the surface of the Klein bottle. This mode enables you to
+see that the Klein bottle is non-orientable. The second mode draws
+the Klein bottle with fully saturated rainbow colors. This gives a
+very nice effect when combined with the see-through bands mode or with
+the orientation markers drawn. The third mode draws the Klein bottle
+with colors that are chosen according to the 4d "depth" of the points.
+This mode enables you to see that the figure-8 Klein bottle does not
+intersect itself in 4d, while the Lawson Klein bottle does intersect
+itself. The rotation speed for each of the six planes around which
+the Klein bottle rotates can be chosen. For the walk-and-turn more,
+only the rotation speeds around the true 4d planes are used (the xy,
+xz, and yz planes). Furthermore, in the walking modes the walking
+direction in the 2d base square of the Klein bottle and the walking
+speed can be chosen. This program is somewhat inspired by Thomas
+Banchoff's book "Beyond the Third Dimension: Geometry, Computer
+Graphics, and Higher Dimensions", Scientific American Library, 1990.

+.PP
+The following six options determine the rotation speed of the Klein
+bottle around the six possible hyperplanes. The rotation speed is
+measured in degrees per frame. The speeds should be set to relatively
+small values, e.g., less than 4 in magnitude. In walk mode, all
+speeds are ignored. In walk-and-turn mode, the 3d rotation speeds are
+ignored (i.e., the wx, wy, and wz speeds). In walk-and-turn mode,
+smaller speeds must be used than in the turn mode to achieve a nice
+visualization. Therefore, in walk-and-turn mode the speeds you have
+selected are divided by 5 internally.
+.TP 8
+.B \-speed-wx \fIfloat\fP
+Rotation speed around the wx plane (default: 1.1).
+.TP 8
+.B \-speed-wy \fIfloat\fP

+.TP 8
+.B \-speed-yz \fIfloat\fP
+Rotation speed around the yz plane (default: 2.1).
+.PP
+The following two options determine the walking speed and direction.
+.TP 8
+.B \-walk-direction \fIfloat\fP
+The walking direction is measured as an angle in degrees in the 2d
+square that forms the coordinate system of the surface of the Klein
+bottle (default: 7.0).
+.TP 8
+.B \-walk-speed \fIfloat\fP
+The walking speed is measured in percent of some sensible maximum
+speed (default: 20.0).
+.SH INTERACTION
+If you run this program in standalone mode in its turn mode, you can
+rotate the Klein bottle by dragging the mouse while pressing the left
+mouse button. This rotates the Klein bottle in 3D, i.e., around the
+wx, wy, and wz planes. If you press the shift key while dragging the
+mouse with the left button pressed the Klein bottle is rotated in 4D,
+i.e., around the xy, xz, and yz planes. To examine the Klein bottle
+at your leisure, it is best to set all speeds to 0. Otherwise, the
+Klein bottle will rotate while the left mouse button is not pressed.
+This kind of interaction is not available in the two walk modes.

+.TP 8
+.B \-style \fIstyle\fP\fP
+Specify which model of lamp to draw. Available models
+are: \fBClassic\fP, \fBGiant\fP, \fBCone\fP, and \fBRocket\fP.
+Default: random.
+.TP 8
+.B \-spin \fIxyz\fP
+Around which axes the model should auto-spin. Defaults to "Z", meaning
+it rotates horizontally, but otherwise pitch or roll.
+.TP 8
+.B \-no-spin
+Same as \fB\-spin ''\fP.
+.TP 8
+.B \-speed \fIfloat\fP
+A number controlling the frequency at which new blobs launch: you can
+think of this as being related to the the heat of the lightbulb in
+the base. Default: 0.003.
+.TP 8
+.B \-delay \fIusecs\fP
+The delay between steps of the animation; default is 30000 (0.03 second.)
+.TP 8
+.B \-resolution \fIinteger\fP
+The size of the grid from which the mesh is created that is used
+to polygonize the blobs. higher values will give very smooth looking
+blobs, at the expense of speed. Default: 40.
+
+The options "-resolution 10 -no-smooth" look kind of interesting.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.TP 8
+.B \-count \fIinteger\fP
+The maximum number of blobs that can be in motion at once.
+Default: 3.
+.TP 8
+.B \-no-smooth
+Turn off smoothing: the objects in the scene will be facetted.
+.TP 8
+.B \-wireframe
+Render all objects in wireframe instead of as solids.
+.TP 8
+.B \-impatient
+Provide this option if you are. This will pre-warm the lamp, so when it
+starts up, the first frame will show a blob already halfway up the lamp.
+.TP 8
+.B \-lava-color \fIcolor\fP
+Specifies the color of the blobbies. Default: red.
+.TP 8
+.B \-fluid-color \fIcolor\fP
+Specifies the color of the fluid that the blobbies float in.
+Default: light blue.
+.TP 8
+.B \-base-color \fIcolor\fP
+Specifies the color of the lamp base, and the cap on top of the bottle.
+Default: very dark gray.
+.TP 8
+.B \-table-color \fIcolor\fP
+Specifies the color of the table that the lamp is sitting on.
+Default: black (meaning it is invisible.)
+.TP 8
+.B \-fluid-texture \fIfilename\fP
+An image file to wrap around the glass.
+
+Note that on most systems, GL textures must have dimensions that are a
+power of two.
+
+Note also that colors and textures are both applied: so, if you apply a
+texture and it isn't showing up, try specifying the corresponding color
+as "white". Otherwise, the combination of the two might be too dark to
+see.
+.TP 8
+.B \-base-texture \fIfilename\fP
+An image file to wrap around the base of the lamp, and the cap on top

+.SH DESCRIPTION
+The \fImolecule\fP program draws several different representations of
+molecules. Some common molecules are built in, and it can read PDB
+(Protein Data Base) files as input.
+.SH OPTIONS
+.I molecule
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.TP 8
+.B \-verbose
+Print debugging info on stderr about files being loaded, etc.
+.TP 8
+.B \-wander
+Move the molecules around the screen.
+.TP 8
+.B \-no\-wander
+Keep the molecule centered on the screen. This is the default.
+.TP 8
+.B \-spin
+Which axes around which the molecule should spin. The default is "XYZ",
+meaning rotate it freely in space. "\fB\-spin Z\fP" would rotate the
+molecule in the plane of the screen while not rotating it into or out
+of the screen; etc.
+.TP 8
+.B \-no\-spin
+Don't spin it at all: the same as \fB\-spin ""\fP.
+.TP 8
+.B \-labels
+Draw labels on the atoms (or the spot where the atoms would be.)
+This is the default.
+.TP 8
+.B \-no\-labels
+Do not draw labels on the atoms.
+.TP 8
+.B \-titles
+Print the name of the molecule and its chemical formula at the top of
+the screen.
+.TP 8
+.B \-no\-titles
+Do not print the molecule name.
+.TP 8
+.B \-atoms
+Represent the atoms as shaded spheres of appropriate sizes.
+This is the default.
+.TP 8
+.B \-no\-atoms
+Do not draw spheres for the atoms: only draw bond lines.
+.TP 8
+.B \-bonds
+Represent the atomic bonds as solid tubes of appropriate thicknesses.
+This is the default.
+.TP 8
+.B \-no\-bonds
+Do not draw the bonds: instead, make the spheres for the atoms be
+larger, for a "space-filling" representation of the molecule.
+.TP 8
+.B \-shells
+Draw transparent electron shells around the atoms. This only works
+if bonds are also being drawn.
+.TP 8
+.B \-no\-shells
+Do not draw electron shells. This is the default.
+.TP 8
+.B \-shell\-alpha
+When drawing shells, how transparent to make them. Default 0.4.
+.TP 8
+.B \-wireframe
+Draw a wireframe rendition of the molecule: this will consist only of
+single-pixel lines for the bonds, and text labels where the atoms go.
+This will be very fast.
+.TP 8
+.B \-timeout \fIseconds\fP
+When using the built-in data set, change to a new molecule every
+this-many seconds. Default is 20 seconds.
+.TP 8
+.B \-molecule \fIfile-or-directory\fP
+Instead of using the built-in molecules, read one from the given file.
+This file must be in PDB (Protein Data Base) format. (Note that it's
+not uncommon for PDB files to contain only the atoms, with no (or
+little) information about the atomic bonds.)
+
+This can also be a directory, in which case, all of the .pdb files in
+that directory will be loaded. A new one will be displayed at random
+every few seconds (as per the \fI\-timeout\fP option.)
+.PP
+When the molecule is too large (bigger than about 30 angstroms from
+side to side), the \fI\-label\fP option will be automatically turned
+off, because otherwise, the labels would overlap and completely obscure
+the display.
+
+When the molecule is around 150 angstroms from side to side, wireframe
+mode will be turned on (because otherwise it would be too slow.)

+.SH DESCRIPTION
+The \fIpolytopes\fP program shows one of the six regular 4d polytopes
+(5-cell, 8-cell, 16-cell, 24-cell, 120-cell, or 600-cell) rotating in
+4d. The program projects the 4d polytope to 3d using either a
+perspective or an orthographic projection. The projected 3d polytope
+can then be projected to the screen either perspectively or
+orthographically. There are three display modes for the polytope:
+mesh (wireframe), solid, or transparent. Furthermore, the colors with
+which the polytope is drawn can be set to either single color or to a
+coloring according to the 4d "depth" (the w coordinate) of the
+polytope in its unrotated position. In the first case, the polytope
+is drawn in red. This coloring combined with transparency gives a
+nice visual effect of the structure of the polytope. The second mode
+draws the polytope with a fully saturated color wheel in which the
+edges or faces are colored accoring to their average 4d "depth". This
+mode is best combined with the wireframe mode, where it allows you to
+see how different parts of the polytope are moved to the "inside" of
+the projected polytope in 3d. Of course, in 4d the cells, faces, and
+edges of the polytope all have the same distance from the center of
+the polytope. Only the projection creates the appearance that some of
+the cells lie "inside" the figure in 3d.
+.SH OPTIONS
+.I polytopes
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8

+.B \-delay \fImicroseconds\fP
+How much of a delay should be introduced between steps of the
+animation. Default 25000, or 1/40th second.
+.PP
+The following six options are mutually exclusive. They determine
+which polytope is displayed.
+.TP 8
+.B \-5-cell
+Display the 5-cell. The 5-cell is the 4d analogon of a regular
+tetrahedron in 3d. It has 5 regular tetrahedra as its cells, 10
+equilateral triangles as faces, 10 edges, and 5 vertices.
+.TP 8
+.B \-8-cell
+Display the 8-cell (a.k.a. hypercube or tessaract). The 8-cell is the
+4d analogon of a cube in 3d. It has 8 cubes as its cells, 24 squares
+as faces, 32 edges, and 16 vertices.
+.TP 8
+.B \-16-cell
+Display the 16-cell. The 16-cell is the 4d analogon of an octahedron

+triangles as faces, 24 edges, and 8 vertices.
+.TP 8
+.B \-24-cell
+Display the 24-cell. The 24-cell has no 3d analogon. It has 24
+regular octahedra as its cells, 96 equilateral triangles as faces, 96
+edges, and 24 vertices.
+.TP 8
+.B \-120-cell
+Display the 120-cell. The 120-cell has no 3d analogon. It has 120
+regular dodecahedra as its cells, 720 regular pentagons as faces, 1200
+edges, and 600 vertices.
+.TP 8
+.B \-600-cell
+Display the 600-cell. The 600-cell has no 3d analogon. It has 600
+regular tetrahedra as its cells, 1200 equilateral triangles as faces,
+720 edges, and 120 vertices.
+.PP
+The following three options are mutually exclusive. They determine
+how the polytope is displayed.
+.TP 8
+.B \-wireframe
+Display the polytope as a wireframe mesh.
+.TP 8
+.B \-surface
+Display the polytope as a solid object.
+.TP 8
+.B \-transparent

+(default).
+.TP 8
+.B \-orthographic-4d
+Project the polytope from 4d to 3d using an orthographic projection.
+.PP
+The following six options determine the rotation speed of the polytope
+around the six possible hyperplanes. The rotation speed is measured
+in degrees per frame. The speeds should be set to relatively small
+values, e.g., less than 4 in magnitude.
+.TP 8
+.B \-speed-wx \fIfloat\fP
+Rotation speed around the wx plane (default: 1.1).

+Rotation speed around the yz plane (default: 2.1).
+.SH INTERACTION
+If you run this program in standalone mode you can rotate the polytope
+by dragging the mouse while pressing the left mouse button. This
+rotates the polytope in 3D, i.e., around the wx, wy, and wz planes.
+If you press the shift key while dragging the mouse with the left
+button pressed the polytope is rotated in 4D, i.e., around the xy, xz,
+and yz planes. To examine the polytope at your leisure, it is best to
+set all speeds to 0. Otherwise, the polytope will rotate while the
+left mouse button is not pressed.

+produced depending on the period, position, and rotation of the component
+planes, and whether the rotation of the planes is evenly distributed around
+the circle (the "symmetric" option, above) or random. See also the

+.SH DESCRIPTION
+This draws a sonar screen that pings (get it?) the hosts on
+your local network, and plots their distance (response time) from you.
+The three rings represent ping times of approximately 2.5, 70 and 2,000
+milliseconds respectively.
+
+Alternately, it can run a simulation that doesn't involve hosts.
+.SH OPTIONS
+.I sonar
+understands the following options:
+.TP 8
+.B \-ping \fIhosts-or-subnets\fP
+The list of things to ping, separated by commas or spaces.
+Elements of this list may be:
+.RS 8
+.TP 12
+.B simulation
+Run in simulation mode instead of pinging real hosts.
+.TP 12
+.I hostname
+Ping the given host.
+.TP 12
+.I A.B.C.D
+Ping the given IPv4 address.
+.TP 12
+.B subnet
+Ping the local subnet. On systems where we can determine the local
+network mask, we use that; otherwise, we assume Class C (254 hosts).
+.TP 12
+.B subnet/\fINN\fP
+Ping a different-sized local subnet: e.g., \fBsubnet/28\fP would ping
+a 4-bit subnet (the nearest 14 addresses). On systems where we can
+determine the local network mask, we always use that.
+.TP 12
+.I A.B.C.D/NN
+Ping an arbitrary other IPv4 subnet. The address specifies
+the base address, and the part after the slash is how wide the
+subnet is. Typical values are /24 (for 254 addresses) and /28 (for
+14 addresses).
+.TP 12
+.I filename
+Ping the hosts listed in the given file. This file can be in the
+format used by \fI/etc/hosts\fP, or it can be any file that has host
+names as the first or second element on each line. If you use ssh,
+try this:
+
+ sonar -ping $HOME/.ssh/known_hosts
+.RE
+.TP 8
+.B \-ping\-timeout \fIint\fP
+The amount of time in milliseconds the program will wait for an answer
+to a ping.
+.TP 8
+.B \-delay \fIint\fP
+Delay between frames, in microseconds. Default 20000.
+.TP 8
+.B \-speed \fIratio\fP
+Less than 1 for slower, greater than 1 for faster. Default 1.
+.TP 8
+.B \-sweep-size \fIratio\fP
+How big the glowing sweep area should be. Default 0.3.
+.TP 8
+.B \-font-size \fIpoints\fP
+How large the text should be. Default 10 points.
+.TP 8
+.B \-no\-wobble
+Keep the display stationary instead of very slowly wobbling back and forth.
+.TP 8
+.B \-no\-dns
+Do not attempt to resolve IP addresses to hostnames.
+.TP 8
+.B \-no\-times
+Do not display ping times beneath the host names.
+.TP 8
+.B \-team-a-name \fIstring\fP
+In simulation mode, the name of team A.
+.TP 8
+.B \-team-b-name \fIstring\fP
+In simulation mode, the name of team B.
+.TP 8
+.B \-team-a-count \fIint\fP
+In simulation mode, the number of bogies on team A.
+.TP 8
+.B \-team-b-count \fIint\fP
+In simulation mode, the number of bogies on team B.
+.TP 8
+.B \-fps
+Display the current frame rate, polygon count, and CPU load.
+.SH NOTES
+On most Unix systems, this program must be installed as setuid root
+in order to ping hosts. This is because root privileges are needed
+to create an ICMP RAW socket. Privileges are disavowed shortly after
+startup (just after connecting to the X server) so this is believed
+to be safe:
+.EX
+chown root:root sonar
+chmod u+s sonar
+.EE
+It is not necessary to make it setuid on MacOS systems, because on
+MacOS, unprivileged programs can ping by using ICMP DGRAM sockets
+instead of ICMP RAW.
+
+In ping-mode, the display is a logarithmic scale, calibrated so that the
+three rings represent ping times of approximately 2.5, 70 and 2,000
+milliseconds respectively.
+
+This means that if any the hosts you are pinging take longer than 2
+seconds to respond, they won't show up; and if you are pinging several
+hosts with very fast response times, they will all appear close to the
+center of the screen (making their names hard to read.)

+Does not support IPv6.

+.SH NAME
+starwars - draws a perspective text crawl, like at the beginning of the movie
+.SH SYNOPSIS
+.B starwars
+[\-display \fIhost:display.screen\fP] [\-window] [\-root]
+[\-visual \fIvisual\fP]
+[\-delay \fImicroseconds\fP]
+[\-program \fIcommand\fP]
+[\-size \fIinteger\fP ]
+[\-columns \fIinteger\fP]
+[\-wrap | \-no\-wrap]
+[\-left | \-center | \-right]
+[\-lines \fIinteger\fP]
+[\-spin \fIfloat\fP]
+[\-steps \fIinteger\fP]
+[\-delay \fIusecs\fP]
+[\-font \fIxlfd\fP]
+[\-no\-textures]
+[\-no\-smooth]
+[\-no\-thick]
+[\-fps]
+.SH DESCRIPTION
+The \fIstarwars\fP program runs another program to generate a stream of
+text, then animates that text receeding into the background at an angle,
+in front of a star field.
+.SH OPTIONS
+.I starwars
+accepts the following options:
+.TP 8
+.B \-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-program \fIsh-command\fP
+The command to run to generate the text to display. This option may be
+any string acceptable to /bin/sh. The program will be run at the end of
+a pipe, and any characters that it prints to \fIstdout\fP will be printed
+on the starwars window. If the program exits, it will be launched again
+after we have processed all the text it produced.
+
+Note that starwars is \fInot\fP a terminal emulator: programs that try to
+directly address the screen will not do what you might expect. This
+program merely draws the characters on the screen left to right, top
+to bottom, in perspective. Lines (may) wrap when they reach the right
+edge.
+
+In other words, programs like
+.BR fortune (1)
+will work, but programs like
+.BR top (1)
+won't.
+
+Some examples:
+.EX
+starwars -program 'cat /usr/src/linux*/README'
+starwars -columns 30 -program 'ping www.starwars.com'
+starwars -left -no-wrap -program 'ps -auxwwf'
+starwars -left -no-wrap -columns 45 -program 'top -bn1'
+starwars -left -columns 40 -program 'od -txC /dev/urandom'
+starwars -font fixed -program 'od -txC /dev/urandom'
+.EE
+.TP 8
+.B \-size \fIinteger\fP
+How large a font to use, in points. (Well, in some arbitrary unit
+we're calling "points" for the sake of argument.) Default: 24.
+.TP 8
+.B \-columns \fIinteger\fP
+How many columns of text should be visible on the bottom line of the
+screen. Default: 60.
+
+Only one of \fI\-columns\fP and \fI\-size\fP may be specified;
+if both are specified, \fI\-columns\fP takes priority.
+.TP 8
+.B \-wrap
+Word-wrap lines when they reach the rightmost column. This is the default.
+.TP 8
+.B \-no\-wrap
+Do not word-wrap: just let the lines go off the right side of the screen.
+.TP 8
+.B \-left | \-center | \-right
+Whether to align the text flush left, centered, or flush right.
+The default is centered.
+.TP 8
+.B \-lines \fIinteger\fP
+How many lines should be allowed to be on the screen before they fall off
+the end. The default is 125.
+.TP 8
+.B \-spin \fIfloat\fP
+The star field on the background slowly rotates. This is how fast.
+The default is 0.03.
+.TP 8
+.B \-steps \fIinteger\fP
+How many steps should be used to scroll a single line. The default is 35.
+If the animation looks jerky to you, increase this number.
+.TP 8
+.B \-delay \fIusecs\fP
+The delay between steps of the animation; default is 40000 (1/25th second.)
+.TP 8
+.B \-font \fIfont-name\fP
+The name of the font to use. For best effect, this should be a large
+font (at least 36 points.) The bigger the font, the better looking the
+characters will be. Note that the size of this font affects only the
+clarity of the characters, not their size on the screen: for that, use
+the \fI\-size\fP or \fI\-columns\fP options.
+
+Default: -*-utopia-bold-r-normal-*-*-720-*-*-*-*-iso8859-1
+.TP 8
+.B \-no\-textures
+Instead of texture-mapping a real font to render the text, use a
+built-in font composed of line segments. On graphics cards without
+texture support, the line-segment font will have much better
+performance.
+.TP 8
+.B \-no\-smooth
+When using the line-segment font, turn off anti-aliasing of the lines
+used to draw the font. This will make the text blockier, but may
+improve performance.
+.TP 8
+.B \-no\-thick
+When using the line-segment font, turn off use of thick lines for the
+characters that are close to the foreground. This will make the text
+appear unnaturally skinny, but may improve performance.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT

+stored in the RESOURCE_MANAGER property.

+.SH DESCRIPTION
+PSR B1919+21 (AKA CP 1919) was the first pulsar ever discovered: a spinning
+neutron star emitting a periodic lighthouse-like beacon. An illustration of
+the signal received from it was published in Scientific American in 1971,
+and later in The Cambridge Encyclopedia of Astronomy in 1977, where it was
+seen by Stephen Morris, the drummer of Joy Division, and was consequently
+appropriated by Peter Saville for the cover of the band's album "Unknown
+Pleasures".

+[\-fps]
+.SH DESCRIPTION
+Draws a randomly-colored Voronoi tessellation, and periodically zooms
+in and adds new points. The existing points also wander around.
+
+There are a set of control points on the plane, each at the center of
+a colored cell. Every pixel within that cell is closer to that cell's
+control point than to any other control point. That is what
+determines the cell's shapes.
+
+When running in a window, you can click to insert a new point at
+the mouse position. Clicking on an existing point lets you drag
+it around.
+
+This implementation takes advantage of the OpenGL depth buffer to
+compute the cells for us, by rendering the intersection of overlapping
+cones in an orthographic plane.
