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