Xchat, What on earth ?
As you all know, Windows xchat binaries are now distributed under a shareware license, And not under the GPL anymore.
A quote from here: 2) My particular Windows release is not released under GPL. Since people's source (patch) contributions have not stated any terms, I have decided to release this under Shareware, to protect the extra work I have done to make a good Windows release. However, I'll always respect peoples wishes. If someone has contributed some code and want it removed, you only have to ask (mail me personally), and it will be done. If this happens, I'll just rewrite the code myself, AND release it under GPL for your pleasure.
