By using a conditionally substituted shell variable, as in this commital:
2006-07-14 Keith Marshall
* pdfroff.sh (PDFWRITE): Local shell variable replaced...
(PDFROFF_POSTPROCESSOR_COMMAND): by this new environment
variable...
(GROFF_GHOSTSCRIPT_INTERPRETER): with this bound to it.
(PDFROFF_COLLATE, PDFROFF_KILL_NULL_PAGES): New environment
variables.
(--no-kill-null-pages): New command line option; implement it,
and...
(--help): Add description for it.
* pdfroff.man (PDFROFF_POSTPROCESSOR_COMMAND): Document it.
(PDFROFF_COLLATE, PDFROFF_KILL_NULL_PAGES): Document them.
(--no-kill-null-pages): Document it.
2006-07-14 Zvezdan Petkovic <[EMAIL PROTECTED]>
* pdfroff.sh (--emit-ps): New command line option; implement it.
(--help): Add description for it.
* pdfroff.man (--emit-ps): Document it.

AFAIK, yes. However, I don't have many variants on which I can test, so
if you discover or know of a problem, please let me know.
This particular construct has been used elsewhere within pdfroff, and
also in our nroff script, for some time now, with no complaints to date.
Regards,
Keith.
