Which country is this in? I doubt that this works the same way all over the world.

(I think -- IANAL, and I'm going on US/California law.) There is no trademark for PHP for the simple reason that it is WAY too expensive to have a worldwide trademark. I can not afford to have a trademark. Because of that, I will keep my license clause as I do not want people to make a derivate called "Xdebug+" for example. Also, I do not care a single bit about whatever law some state in the US has, it's not of my concern. regards, Derick -- Xdebug | http://xdebug.org | [EMAIL PROTECTED]
