Changes

Allegations have surfaced that [[Rybka|Rybka 1.0 beta]] <ref>[http://www.chess.com/download/view/rybka-beta-10 Rybka 1.0 beta]</ref> and other versions of Rybka are derivatives of [[Fruit|Fruit 2.1]] and [[Crafty]]. If versions of Rybka are derived from Fruit and participated in ICGA tournaments, then Rybka has violated [[ICGA Tournament Rules]]. Fruit 2.1 <ref>[http://arctrix.com/nas/chess/fruit/ Fruit 2.1]</ref> source code was distributed with a [https://icga.wikispaces.com/fruit+copying.txt specific license]. Part of this license reads "For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights." Allegations state that by distributing Rybka which is based on Fruit, this GNU license was violated. The ICGA rules state "Programming teams whose code is derived from or including game-playing code written by others must name all other authors, or the source of such code, in the details of their submission form.". No such notification was included in the Rybka entry forms.
