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. http://packages.qa.debian.org/c/crafty.html
