As I just learned there are (at least) three overlays using
bzr.eclass, namely desktop-effects, emacs, and ltsp.
So I think it is justified to move bzr.eclass to the Portage tree.

Please raise your objections *now*.

source control management system).
# The eclass was originally derived from the git eclass.
#
# Note: Just set EBZR_REPO_URI to the url of the branch and the src_unpack
# this eclass provides will put an export of the branch in ${WORKDIR}/${PN}.
