Of course, most or all of the other versions of troff can also do this,
with more or less effort.  For example, with ditroff and Transcript you can
use psfig, and Elan's eroff and SoftQuad's sqtroff have built in requests
for including bitmaps and/or PostScript graphics.  So I think do the other
commercial versions of troff.

If you use the troff back-end that Chris Lewis wrote (`psroff'), you can even
do this with the old C/A/T troff, I understand.

I don't like the BP mnemonic for PostScript Illustration, by the way :-)  We
named a macro for including illustrations ILLUST, which seems to make more
sense -- BP sounds suspiciously like Begin Page to me.  Presumably by now the
ancient 2-character restriction on macro name length has been lifted in DWB?

In what way does Picasso do this better than other programs which do it,
that justifies `particlarly good'?  We've had no problem using a wide range
of PostScript files, including those from Adobe Illustrator and other Mac
programs, public-domain drawing programs and others.
