+Migration from bazaar
+=====================
+
+If you have existing bazaar branches and want to move them to a git repository,
+there are several options:
+
+* download http://nightly.openerp.com/move-branch.zip and run it with
+  `python move-branch.zip -h` (for the help). It should be able to convert
+  simple-enough branches for you (even if they have merge commits &al)
+* Extract the branch contents as patches and use `git apply` or `git am` to
+  rebuild a branch from them
+* Replay the branch by hand
