.SH DESCRIPTION
The \fIrd-bomb\fP program draws reaction/diffusion textures. The code
.TP 8
.B \-diffusion \fIn\fP
These are constants in the equations that effect its visual nature.
-Each may be one of 0, 1, or 2.
+Each may be one of 0, 1, or 2. Default is -1: these constants are
+chosen randomly.
.TP 8
.B \-radius \fIn\fP
Size of the seed.
.TP 8
-.B \-palette \fIn\fP
-Selects a palette. Must be between 0 and 80, inclusive.
-.TP 8
.B \-size \fIf\fP
What fraction of the window is actively drawn, a floating point number
-between 0 (exclusive) and 1 (inclusive). Default is 0.66.
+between 0 (exclusive) and 1 (inclusive). Default is 1.0.
.TP 8
.B \-speed \fIf\fP
When a fraction of the screen is active, the active area moves at this
rate (a floating point number). Default is zero. Suggested value: 1.0.
.TP 8
-.B \-delay \fIusecs\fP
-How many microseconds to delay between frames; default 1000, or
+.B \-delay \fImillisecs\fP
+How many milliseconds to delay between frames; default 1, or
about 1/1000th of a second.
+.TP 8
+.B \-fps
+Display the current frame rate and CPU load.
