Is there a public domain version of regex(3) ? (YES!)

[Guido van Rossum]

In article <6237 at mcvax.UUCP> I asked if there were any public domain
versions of regex(3).  I got many replies, both helpful suggestions
where to look and messages saying "mail me what you've got".  Thanks
to all who responded; for those who wanted to see what I got, here's
a summary.

The most important message (for me) was one quoting Mark Horton saying
that the regex.c that comes with BSD *is* public domain (though it has
nothing to do with the regex(3) in System V, which is certainly *not*
public domain).

I also got several pointers to various public domain packages that do
regular expression matching:

    Richard Stallman's public-domain version of UNIX (GNU) has one;
	contact RMS at MIT-MC.ARPA
    Larry Wall's "rn" has r.e. matching in search.[ch] (ripped out of emacs
	and made more general); see net.sources or contact sdcrdcf!lwall
    Kernighan & Plaugher, Software Tools in {C, Pascal}, Addison-Wesley;
	contact your local computer bookstore
    The DECUS C distribution should have one; maybe it's in DECUS grep.
    John Pierce has a version; sdcsvax!sdchema!jwp
    Dave Tilbrook's QED/TIPS (not sure if it's public domain?
	contact mcvax!qtlon!ist!dt)

If you want more specific info, drop me a note, and I'll mail you the
full file of responses.
