HPGL previewer for SUN needed

[Shalom Krischer]

Hello world...I would like to take a file in HPGL (at least I think it is
HPGL...it is produced by nroff/troff and printed very nicely on an LJII)
and look at the output (exactly as it would look printed) before I print
it.  I think I remeber hearing about such a tool for the SUN, but, I
cannot remember what or where...  Thanks in Advance....
