Ever since the main Wine tree changed its license to the LGPL, a fork of the tree under the old license had seemed necessary, and been planned. This fork is now ready.
If you're a Wine contributor that don't care all that much about forking, you do not need to leave the official LGPL-ed Wine tree to let the X11-licensed fork live. All you have to do is to agree to license your patches under the X11 license, so we are able to pick it up from wine-patches and apply it to the X11 tree whenever possible. This will make your contributions more widely used, so we encourage as many as possible to do so. And if it's out of the question for you, then we encourage you to tell us that, so that we know that we can never apply your patches.
The fork's name was decided after a lot of brainstorming by Eric and me, when we found a name which we both liked... ReWind. It can stand for "Re-engineering Windows", or something like "Rewind to the old Windows days".
The fork is currently hosted on SourceForge. The homepage is thus http://rewind.sourceforge.net/ for now. It's not a very fancy page, but all the necessary CVS and mailing list information is there. Go there if you're interested in contributing actively to ReWind. Patches known to come from X11-friendly contributors are already applied to the CVS, but many more patches are waiting for the authors to declare a stance.
The CVS repository that ReWind is based on is the WineHQ repository, cleansed of all post-LGPL commits (except the Before-LGPL tag), so all the CVS history of the pre-LGPL Wine is present in the ReWind CVS repository. This ensures that no history is lost in the event that the X11 fork prevails over the LGPL fork.
Your help to achieve this is welcome.
Followups to this post should preferably go to wine-license.
Thanks for your attention.
