It's one CVS tree. You need two checked-out source trees if you wish to track both branches. I don't see any other way to do it easily. The way things are being kept in synch (for the most part), I don't see a particular need for anyone to track both branches unless they're really gung-ho about it. Good idea. Correct. Assuming XEmacs doesn't die out in the interim, I think this should be reversed in the future -- ie. the bleeding edge version is always the default branch and the stable version is the forked branch. Yes. The plan has been to do this when 21.0.final is made.
