The \!, .cf, and .sy commands allow you to send data directly to the post
processor.  These have been in ditroff since it was first released in DWB 1.0.
It was in previous, internal versions of ditroff that I used in '82-'84.

We have had a set of macros designed to be used with devps that allow PostScript
file inclusion (e.g., Mac graphics), PostScript special effects (e.g., rotation)etc., since early last year.  Since the postprocessor is designed to accept
information passed this way, it requires no processing of the postprocessor's
output.  This technique really isn't new.  I suggest you look at a copy of
Topics in C Programming (Kochan & Wood, Sams 1987) for a sample of what
integrated Mac and troff looks like.
