Breezy doesn't support Windows at the moment. We need a more concerted effort to get it to work again, possibly coordinated on the mailing list.

I got it to the point of making Windows installer, see https://bazaar.launchpad.net/~a1s/brz/3.2/revision/7557

Now I'm trying to fix as many regression tests as I can.
