Parameters	branches	The Launchpad Branches to upgrade.
	target_dir	The directory to store upgraded versions in.

@classmethod
def finish_all_upgrades(cls, target_dir, logger):

Upgrade listed branches to a target directory.

Parameters	branches	The Launchpad Branches to upgrade.

def finish_upgrade(self):

Create an upgraded version of self.branch in self.target_dir.

def add_upgraded_branch(self):

def create_upgraded_repository(self):
