There is no problem with the GPL. I don't think that complies. From http://www.gnu.org/copyleft/gpl.html : ============================================================================ 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) ============================================================================ Look at b). and in particular: "... at no charge to all third parties ..." >>2.

Are you saying that if Fabien uses code from 2.1 in >subsequent versions he has to release the code from those versions? The originator of a GPL tool owns rights to the code. Ideas from Thomas Gasch that were "cut and paste" would be a violation. >So isn't that saying that the owner/author of code gives up his right to own >(close it if he wants) code once he makes it GPL? That is definitely a misinterpretation. Or at least, that is a misinterpretation of the common use of GPL. There are many examples where people have GPL and commercial versions of the same tool systems. >Further, the author of Toga can write and send versions of his largely >derivative program to selected persons without releasing source? He can't. But that should be open to some interpretation also. If he makes a general public release, he will have to make that base open source. But during development, I think it is absurd to assume that he has to make every change he makes immediately available. >So the conclusion I arrive at is that Fabien and anyone else is a *** fool for >ever giving us a free gpl engine. > >Please consider this a warning all you brilliant chess programmers out there >with original ideas: > >Do *not* release your sources.

I am not a fan of the GPL license (I prefer BSD style). But there is nothing really wrong with it. It's just a preference for me.
