Fast how-to
To checkout a branch, enter at the top-level of the branch directory and run::
$ bzr checkout <url_for_the_branch>
Observation: IIRC, bzr branches are equivalent to cvs modules.
So, whenever you want to update a branch, does as you would do with cvs::
$ cd <top-level of the branch dir>
$ bzr update
