+.SH DESCRIPTION
+This program renders 160 different 3D solids, and displays some
+information about each. A new solid is chosen every few seconds.
+
+There are 75 uniform polyhedra, plus an inifinite number of
+prisms and antiprisms:
+
+ * Convex Uniform Polyhedra:
+ * Platonic solids (5)
+ * Archimedean solids (13)
+ * Convex prisms and antiprisms (2 infinite families)
+ * Nonconvex Uniform Polyhedra:
+ * Kepler-Poinsot polyhedra (4)
+ * Nonconvex uniform polyhedra (53)
+ * Nonconvex prisms, antiprisms, and crossed antiprisms
+ (3 infinite families)
+
+Representative samples of the prism sets brings the total to 80 solids.
+Including the \fIdual\fP of each brings the total up to 160. (To
+create the "dual" of a polyhedron, faces are replaced with vertices,
+and vertices with faces.)
+.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 \-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
+.TP 8
+.B \-speed \fInumber\fP
+Larger numbers mean run faster. Default: 1.0.
+.TP 8
+.B \-duration \fIseconds\fP
+How long before switching to a new polyhedron. Default 12 seconds.
+.TP 8
+.B \-wander | \-no-wander
+Whether the objects should wander around the screen.
+.TP 8
+.B \-spin [XYZ] | \-no-spin
+Which axes, if any, to spin around on.
+.TP 8
+.B \-titles | \-no-titles
+Whether to display text describing each object.
+.TP 8
+.B \-which \fIobject-name\fP
+Display only one particular object, identified by number, name, or
+Whthoff symbol.
+.TP 8
+.B \-wireframe | \-no-wireframe
+Render in wireframe instead of solid.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH KEY BINDINGS
+When running in a window, you can rotate the object with the mouse.
+Also, the following keystrokes are defined:
+.TP 12
+.B SPC \fIor\fP TAB
+Select a new polyhedron at random.
+.TP 12
+.B + \fIor\fP >
+Select the next-higher-numbered polyhedron.
+.TP 12
+.B - \fIor\fP <
+Select the next-lower-numbered polyhedron.
+.TP 12
+.B ESC \fIor\fP ^C
+Quit.
+.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.
