Here is a patch that adds support for shared repositories. Since bzr
is still a bit slow this is quite useful when using multiple branches.
For example I have modified the live emacs(-cvs) ebuild to use the bzr
mirror of emacs instead of cvs. I also have my own emacs branches, and
sometimes want to install from one of these and at other times from
trunk. Without support for shared repositories this would require the
standalone branches to be manually moved out of the way everytime I
want to switch branches. (Or worse the complete tree to be checked out
from scratch every time I switch branches.)
Please consider these changes
Jonas

# Note: Just set EBZR_REPO_URI to the url of the branch and the src_unpack
