.SH DESCRIPTION
-The \fIglmatrix\fP program draws dropping characters similar to what
-is seen in the title sequence of the Wachowski brothers' film,
-"The Matrix".
+The \fIglmatrix\fP program draws the 3D "digital rain" effect, as seen
+in the title sequence of the Wachowski brothers' film, "The Matrix".

.BR xmatrix (MANSUFFIX)
By default, waves of color roll down the columns of glyphs. This
argument disables that.
.TP 8
+.B \-no-rotate\fP
+By default, the scene slowly tilts and rotates. This
+argument disables that.
+.TP 8
.B \-binary\fP
Instead of displaying Matrix glyphs, only display ones and zeros.
.TP 8
Instead of displaying Matrix glyphs, display genetic code
(guanine, adenine, thymine, and cytosine.)
.TP 8
+.B \-clock\fP
+Hide a clock displaying the current time somewhere in the glyphs.
+.TP 8
+.B \-timefmt\fP \fIstrftime-string\fP
+How to format the clock when \fI\-clock\fP is specified.
+Default "\ %l%M%p\ ".
+.TP 8
+.B \-speed \fIratio\fP
+Less than 1 for slower, greater than 1 for faster. Default 1.
+.TP 8
.B \-wireframe
Just draw boxes instead of textured characters.
.TP 8
.B \-fps
-Display a running tally of how many frames per second are being rendered.
-In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
-your GL performance.
+Display the current frame rate, CPU load, and polygon count.
