It would be really good if you put some of these 'bzr good workflow
practices' in the wiki dev guidelines page. Feel free to make it all
rst right away: that way when Brian integrates the docs, he can just
grab it from there. Moin renders rest just fine, with a directive:
You have a *much* better sense for how to work with, rather than
against, bzr. We'd all benefit from that insight before we mangle the
ipython tree into a crazy mess...
The single commit per bugfix is probably also a good policy because
I'm starting to get the feel that there's ONE file that is going to
give us grief: the linear ChangeLog. That's the one file where
conflicts are likely to appear if we all edit it, so we might be
better off probably NOT using it anymore, and relying on the commit
logs instead. But for that to be viable, the commit logs must be a
suitable replacement of the current Changelog, so they need to have an
entry per actual change, and must be more than one-liners. Otherwise
there will be no easily human-readable log later anywhere. Does that
