I asked a couple of days ago about some simple way to get an EPS version of a
plain ASCII file.  After fooling, unsuccessfully, with enscript for a while,
I decided to just leap in and fix it up brute force.  Attached is a little
shell script that'll get you a PostScript rendering [that \psfig likes, which
is what I was after in the first place!].
