12 # @BLURB: This eclass provides support to use the Bazaar VCS
13 # @DESCRIPTION:
14 # The bzr.eclass provides support for apps using the Bazaar VCS
15 # (distributed version control system).
16 # The eclass was originally derived from the git eclass.
17 #
18 # Note: Just set EBZR_REPO_URI to the URI of the branch and the src_unpack()
19 # of this eclass will put an export of the branch in ${WORKDIR}/${PN}.
