        Hi,

        I've downloaded Ace Bot, trying it and look at the source code : really great job !
I would be happy if I could add Ace Bot in my mod.
Since december 2001 the Quake2 engine and the Dll were released under the term of the GPL license
(thanks to John Carmack). My mod is also covered by the GPL license.

Can your code be integrated in a GPL project ?
More info about the license at www.gnu.org

The current MOD I work on : http://www.coopordie.com

    Best regard

    Pat

De: <> A: "Steve Yeager" <> Objet: Re: About Ace bot Date: lundi 29 juillet 2002 15:51 I'm really happy by your answer. I worked during the last week-end on your code and I must tell you it is really clear and well commented. But could you really confirm you are OK about the GPL. I'm not a lawyer but regarding to this part of your headers file : // This program MUST NOT be sold in ANY form. If you have paid for // this product, you should contact Steve Yeager immediately, via // the ACE Bot homepage. I must inform you that the GPL authorize (with conditions) redistribution on commercial package, like Redhat does with Linux. Of course it can't be integrated in proprietary software, all code will always stay open source, all authors need to be mentioned, and source code need to be available for every derived work ... The GPL license was the choice of John Carmack for Quake1 and Quake2 and many others big open-source projects like Linux. I hope it will agree with you. Distributing your work under the GPL doesn't remove your initial copyright and your right to make absolutely what you want with your code.
If you want more info or discuss about that, feel free to email me or look at www.gnu.org
De: "Steve Yeager" <> A: <> Objet: Re: About Ace bot Date: mercredi 31 juillet 2002 00:34 Yeah, I have to code for a living, so it helps ME when I have to go back and figure out what I did... YES to the GPL. I've dealt with it before. The only reason I put that statement in was I was clueless about the GPL at that time, otherwise it would have been released with either GPL or LGPL. Good luck on your project. Steve Yeager
