For users of Arbortext's DVIPS PostScript driver, heres a macro to enable
   (1)  the inclusion of straight PostScript files or
   (2)  graphics output from the DI-3000/PICSURE PostScript driver
directly into TeX/LaTeX files. It may be nested within LaTeX floating
bodies, or used directly.
Our DI-3000/PICSURE runs on VMS VAXs. Our lasers are QMS800/PS.
