What's the best way for a PostScript program to tell what kind of device it's
printing on?  Basically, I would like a program to be able to notice that
it is running under GhostScript, for example, instead of on a LaserWriter
(Don't ask why...).  Probably the way to do this is to test for the existence
of certain dictionary entries; any suggestions as to which are the best ones
to look for?  (Remember that most previewers have a stubbed-out definition of
statusdict, so it's not a trivial problem.)
