Sure, its attatched to the end of this message.  I've included the C
code, plus a demo program for the regexp stuff that generates an Emacs
TAGS file for Scheme programs.  (I know that etags already does this,
but it was the only thing I could think of at the time, to test the
regexp stuff properly)

I've also included some extensions to string handling in written in
Scheme.  This is part of my overall plan to implement the best bits of
Icon in Scheme (and Elk in particular).  Next on the list is Icon
Csets (this will require some C).  I'll mail it to you when I've
finished, if you want.


PS you need to compile the regexp code with -DELK in the CFLAGS so
that the extensions will work.
