.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.
.B \-root
Draw on the root window.
.TP 8
-.B \-count integer
+.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 integer
+.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 microseconds
+.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.
