Oops.  Those Reply-to settings caught me out again, and I sent

Apologies, Werner, for the duplicate.

Perhaps, as a specialised option for EPS handling; for a more
generally useful option, to pass arbitrary GhostScript control
settings, I think not.

Given that pdfroff follows troff's own model, with a single output
stream appearing on `stdout', how would such a series of output
documents be produced?

I can understand the requirement for a PDF document to include EPS
elements, but is there any real practical application for emitting
what could more usefully be kept as EPS, just to prove that it can
be represented as PDF?  I'm reluctant to divert my limited time to
something that may turn out to be no more than an esoteric proof
of concept.

Keith.
