57 .B \-density \fIpercentage\fP
58 The approximate percentage of the screen that should be filled with
59 characters at any given time. Default 75%.
61 When running in a window, typing \fB+\fP will increase the density and
62 typing \fB-\fP will decrease it. Typing \fB0\fP will momentarily
65 .B \-top\fP | \fB\-bottom\fP | \fB\-both
66 If \fB\-top\fP is specified, the characters will only drop in from the
67 top of the screen as sliding columns of characters. If \fB\-bottom\fP
68 is specified, then instead of sliding columns, the characters will appear
69 as columns that grow downwards and are erased from above. If \fB\-both\fP
70 is specified, then a mixture of both styles will be used. The default

106 Instead of displaying random characters, display the output of a subprocess,
109 .B \-program \fIsh-command\fP
110 The command to run to generate the text to display. This option may
111 be any string acceptable to /bin/sh. The program will be run at the
112 end of a pty or pipe, and any characters that it prints to
113 \fIstdout\fP will be placed in the feeders for xmatrix. If the program
114 exits, it will be launched again after xmatrix has processed all the
