I'm pleased to announce the first version of bzr-autoreview, a Bazaar plugin for automating Launchpad merge proposal reviews.
The concept is simple. Go to your local mirror of a branch on Launchpad, and simply type bzr autoreview. The plugin will do the rest. It finds every merge proposal against your public branch that doesn't yet have a review, gives you an editor pre-populated with the diff, and then, after your review, allows you to also vote.
I have many planned features, but I've been trying this year to release code instead of just writing it. The code's a mess because I was spanning hemispheres while writing it. I plan on cleaning it up in the next few days and releasing again.
Please see the README. You can download the tarball or get the branch. If you're really ambitious, I'd appreciate any patches, so please see the HACKING file. A special thanks goes to Elliot for giving me the idea in the first place.
