[Groff] Embedding postscript directly

[Andrew Khan]

Hi,

Is there any way I can embed postscript directly into my groff document so
that it is not affected by groff and emerges unchanged in the generated
postscript?

The reason I want to do this is so that
I can insert some special postscript tags into the generated postscript and
then post process these (in order to insert an image from an external file).

Many thanks
Andy
