Hello,
can you please help me with the following license text from Crafty
chess program? I think its BSD-like or MIT-like license. I would like
to create Fedora package for it. Its very nice and strong chess
engine. It should be ok (its distributed with Debian) but I would like
to have official explicit confirmation. I do not know which "license
string" should I put in the RPM spec file.
Thank you.
The license can be found in the source distribution in the file main.c.

This doesn't look free.

This license is clearly non-free, for a number of reasons, and I'm
rather surprised that Debian includes it (well, I'm not really
surprised, but this isn't even close to being Free).
Not acceptable for Fedora, sorry. Please let me know if you want me to
open a dialog with the upstream about possible relicensing.

Debian appears to have it in non-free.
