+# @DESCRIPTION:
+# The bzr.eclass provides support for apps using the bazaar DSCM
+# (distributed 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}.
