-* 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
