Hadn't noticed that. (I've always been a hack first read standards
later kind of guy.) Good that means that the job is almost trivial. I
love it when most of the work has already been done for me.

Very simple. In the LPD setup that I have been working on you can
insert arbitrary filters into the processing path. That is what I took
pstops and turned it into ppdfilt for. I stick it in the filter path
just before something is sent to the printer and voila I have PPD
support. I figure I can get ppdfilt or another program to do the same
sort of thing without much trouble for binary non-PS files. Then I
just stick it in the filter chain after gs and viola limited PPD
support for non-PS printers.
