/*
* ansiprt.c
*
* Simple filter to wrap ANSI media copy escape sequences around
* text on stdin. Writes /dev/tty to get around things that might be
* trapping stdout. This is actually a feature because it was written
* to be used with pine's personal print option set up to take "enscript"
* output and send it displayward to be captured/printed to a postscript
* device. Pine, of course, uses popen() to invoke the personal print
* command, and interprets stdout as diagnostic messages from the command.
