true, though the devs still use it and release bug fixes.

Theres nothing to rule out folks taking active ownership of dev work on the project, eg take the time to go to their svn repo http://www.seas.upenn.edu/~bcpierce/unison//svn-instructions... and eg run hg/git/darts import on the repo...

Also, if you look at the svn repo, its been touched with as recently as the past 8 weeks. thats pretty good for a project thats not active
