O.k. I know when I'm licked. Everyone who has responded is in agreement that I don't know what I'm talking about. I'm still trying to find an amicable resolution though.
Again assuming an otherwise Debian free license, can Prof. Hyatt add a restriction that all chess tournaments entries based upon his original source be clearly labeled and entered as "Crafty" or "a Crafty clone" and still be Debian free. Of special importance here I believe would be paragraph 4 which states in part, "The license may require derived works to carry a different name or version number from the original software."
