That's what I was driving at, but with an extra step.  Having it as
an EPS, however, permits the integration to be a bit more seamless.
James Clarke's code, for example, does precisely this.  But without
a little handwaving or hand-crafting, the autoscaling provided
by groff (or psfig/pspic + ditroff) won't work.  Ie: the EPS bounding
box will be rotated 90 degrees from what is desired.  If the picture
is square, great, but to do the job "properly", the EPS BoundingBox
has to be fudged (numbers shuffled).

To the original poster - while you may not have groff, most of the
other ditroffs do support this one way or another.  Psfig, in particular,
when added to generic ditroff (with Transcript or psroff PostScript
drivers) is close to groff capability, but not quite as seamless.
I wouldn't abandon troff for TeX just because of this.

Furthermore, if you have CAT troff instead of DWB, you can *still*
do this, but ONLY if you're using psroff 3 as your PostScript driver.
With psfig for that matter for more seamless operation.

[I should point out that DWB 3 is more-or-less equivalent to groff
in this regard, *if* you have DWB 3 instead of DWB 2.]

It's worth perusing the comp.text FAQ on this topic.
