I know there's at least one person who uses evolve all day every day
and was *not* intimately involved in its development: me. evolve
works, and it works much better today than it did six or eight or nine
months ago.

So if you have problems, either subtle/infrequent problems or great
big showstoppers, please report them to evolve-testers at selenic.com! Or
open a bug at https://bitbucket.org/marmoute/mutable-history.
