-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 pipe, and any characters that it prints to \fIstdout\fP will be printed
-on phosphor's window. The characters will be printed artificially slowly,
-as per the \fI\-delay\fP option above. If the program exits, it will be
-launched again after 5 seconds.
-
-Note that phosphor is \fInot\fP a terminal emulator: programs that try to
-directly address the screen will not do what you might expect. Phosphor
-merely draws the characters on the screen left to right, top to bottom.
-Lines wrap when they reach the right edge, and the screen scrolls when
-characters reach the bottom.
-
-In other words, programs like
-.BR fortune (1)
-will work, but programs like
-.BR top (1)
-won't.
