+.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.
+.SH OPTIONS
+.I boing
+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 \fIusecs\fP
+The delay between frames of the animation, in microseconds: default 15000.
+.TP 8
+.B \-smooth
+Draw a smooth sphere instead of a faceted polyhedron.
+.TP 8
+.B \-lighting
+Do shaded lighting instead of flat colors.
+.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
+.B \-size \fIratio\fP
+How big the ball is; default 0.5 meaning about half the size of the window.
+.TP 8
+.B \-parallels \fIn\fP
+.B \-meridians \fIn\fP
+The pattern of rectangles on the ball. Default 8x16.
+.TP 8
+.B \-wireframe
+Look crummy.
+.TP 8
+.B \-fps
+Display the current frame rate, CPU load, and polygon count.
+.SH ENVIRONMENT
+.PP
+.TP 8
