I wrote & posted a completely PD m4 sometime ago. If you cannot get it from
a nearby archieve site, just ask. It is small enough to be mailed.

As for usage of: I really do not know. M4 can do a lot, but it can get
very hairy: lisp parens are nothing compared to m4 quotes. Having written
PD m4, I really think a better macro processor is needed (cpp is NOT it.),
as m4 macro technology is "prehistoric" (can you say TRAC ? :-|) to put it
mildly. [Is there anything better out there ??]

There is a PD cpp if you are after C-style macros. Again, check your
neigborhood archieve.
