.SH NAME
xmatrix - simulates the computer displays from the movie
[\-top | \-bottom | \-both]
[\-small | \-large]
[\-trace]
+[\-mode \fImode\fP]
[\-phone \fInumber\fP]
.SH DESCRIPTION
-The \fIxmatrix\fP program draws dropping characters similar to the
-displays in the Wachowski brothers' film, "The Matrix".
+The \fIxmatrix\fP program draws dropping characters similar to what
+is seen on the computer monitors in the Wachowski brothers' film,
+"The Matrix".
+
+Also see
+.BR glmatrix (MANSUFFIX)
+for a 3D rendering of the similar effect that appeared in the title
+sequence of the movie.
.SH OPTIONS
.I xmatrix
accepts the following options:
.B \-density \fIpercentage\fP
The approximate percentage of the screen that should be filled with
characters at any given time. Default 75%.
+
+When running in a window, typing \fB+\fP will increase the density and
+typing \fB-\fP will decrease it. Typing \fB0\fP will momentarily
+drain the screen.
.TP 8
.B \-top\fP | \fB\-bottom\fP | \fB\-both
If \fB\-top\fP is specified, the characters will only drop in from the
as columns that grow downwards and are erased from above. If \fB\-both\fP
is specified, then a mixture of both styles will be used. The default
is \fB\-both\fP.
+
+When running in a window, typing \fB[\fP will switch to top-mode,
+typing \fB\]\fP will switch to bottom-mode, and typing \fB\\\fP will
+switch to both-mode.
.TP 8
.B \-small\fP | \fB\-large
These options specify the sizes of the characters. The default
is \fB\-large\fP.
-
.TP 8
-.B \-trace
+.B \-mode trace
Start off with a representation of a phone number being traced.
When the number is finally found, display The Matrix as usual.
+This is the default.
.TP 8
.B \-phone\fP \fInumber\fP
The phone number to trace, if \fB\-trace\fP is specified.
+.TP 8
+.B \-mode crack
+Start off by shutting down the power grid.
+.TP 8
+.B \-mode binary
+Instead of displaying Matrix glyphs, only display ones and zeros.
+.TP 8
+.B \-mode hexadecimal
+Instead of displaying Matrix glyphs, display hexadecimal digits.
+.TP 8
+.B \-mode dna
+Instead of displaying Matrix glyphs, display genetic code
+(guanine, adenine, thymine, and cytosine.)
+.TP 8
+.B \-mode ascii
+Instead of displaying Matrix glyphs, display random ASCII characters.
+.TP 8
+.B \-mode pipe
+Instead of displaying random characters, display the output of a subprocess,
+as ASCII.
+.TP 8
+.B \-program \fIsh-command\fP
+The command to run to generate the text to display. This option may
+be any string acceptable to /bin/sh. The program will be run at the
+end of a pty or pipe, and any characters that it prints to
+\fIstdout\fP will be placed in the feeders for xmatrix. If the program
+exits, it will be launched again after xmatrix has processed all the
+text it produced.
+
+For example:
+.EX
+xmatrix -program 'echo Hello World'
+xmatrix -ascii -program 'ps -eo comm | rev'
+xmatrix -program 'od -txC -w6 /dev/random'
+xmatrix -program 'cat /dev/random'
