annotate MoinMoin/util/forms.py @ 0:5568cf133caf moin20-repo-reboot

create moin/2.0 repo, drop all history (see notes below) Up to now, we used the moin/2.0-dev repository (which was cloned from another, older moin repo quite some time ago). Over the years, these repositories got rather fat (>200MB) and were a pain to clone over slow, high-latency or unreliable connections. After having finished most of the dirty work in moin2, having killed all the 3rd party code we had bundled with (is now installed by quickinstall / pip / setuptools), it is now a good time to get rid of the history (the history made up most of the repository's size). If you need to look at the history, look there: http://hg.moinmo.in/moin/2.0-dev The new moin/2.0 repository has the files as of this changesets: http://hg.moinmo.in/moin/2.0-dev/rev/075132a755dc The changeset hashes that link the repositories will be tagged (in both repositories) as "moin20-repo-reboot".
