All of this should work, including images, though that I haven't done
personally.

The part that may get you is that if the included EPS file doesn't place
its definitions into a dictionary, you will run out of dictionary space.
You will have to increase the dictionary size in order to be able to
include the EPS file.

I do a few neat things with groff and I plan on posting a description of what
I do to get it to work.  I've combined the power of groff and the power of
PostScript and done some fancy things.  Soon I plan and providing examples
of what I have done.  Maybe someone else could use what I have done.
