This Debian GNU/Linux package of crafty was put together by Paul Serice
<ugs@debian.org> from source and data files obtained from:
	ftp.cis.uab.edu:/pub/hyatt/

Crafty has a new copyright/license.  It can be found found in main.c
of the original source distribution.  At the bottom of this file is a
copy of the old license and an e-mail correspondence concerning the
old copyright/license.  I am continuing to distribute the old
information because I believe it to be relevant to the current
situation.

Does this copyright mean Crafty cannot be redistributed by the usual
Debian CD redistributors?  Well, I asked Prof. Hyatt this exact
question via e-mail.  The conversation was as follows:

not a problem with me at all...

no...  I simply don't want someone to market crafty as a chess program.
Including it with something else is fine, knowing that there will be
newer (and better) versions for free on my ftp machine anyway.  I put
that restriction in because there was a company that was making waves
about "Crafty is just too strong to be free, we are going to modify it
a little and then sell it..."
