Henry, I am CC'ing this to the PostgreSQL group.  (See
www.postgresql.org for more info.)  Hey folks, guess who wrote our regex
stuff.  

	Copyright 1992, 1993, 1994 Henry Spencer.  All rights reserved.

Henry, will the new code you write be in the public domain, or only part
of BSDI?  Would you recommend we replace our regex stuff with something
else?  Do you have any patches you would like us to test?

The new regex code will be under essentially the same redistribution terms
as the old stuff (in fact, slightly more generous).  BSDI didn't end up
contributing to this particular project, and the folks who did were all 
happy with open redistribution.

I should clarify that this code isn't "to be written" -- it already exists,
although I'm not entirely happy with it yet and want to limit distribution
until it's tidied up somewhat.

> Would you recommend we replace our regex stuff with something else?

My only real competitor :-) right now appears to be the GNU rx package,
and I have heard enough grumbling about it that I hesitate to recommend
it for general use.  It's faster but it has problems, is my impression;
I have not examined it closely.

> Do you have any patches you would like us to test?

Nothing quite yet.  Incidentally, the new code is a from-scratch
reimplementation, not just patches to the 4.4 one.

	And...we wouldn't sully our code with a GNU license anyway :)  We
are being very very careful about that...

Ah yes, there's that...  As one of my friends calls it, the "GNU Public
Virus"...
