+.SH DESCRIPTION
+The \fIhyperball\fP program displays a wireframe projection of a hyperball
+which is rotating at user-specified rates around any or all of its four axes.
+.SH OPTIONS
+.I hyperball
+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 20000, or about 0.02 seconds.
+.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 ball should be rotated around the specified axis at
+each frame of the animation, expressed in 0.001 radians.  These should be small
+floating-point values (less than 50 works best.)  Default: xy=3,
+xz=5, yw=10.
+.TP 8
+.B \-fps
+Display the current frame rate and CPU load.
+.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.
