[Groff] Is it possible to insert PostScript file in groff?

[Mike Iokhvin]

Hello All!

I need to make the document with groff -me, and I need to insert some 
pictures in the document. I try to make it with grn (by converting picture 
to plot, plot to gremlin), but it is not realy good (b&w only...). 

Is it another possibility to insert picture (PostScript or something else) 
in groff document?
