# * release commits, if any, are of the form 'Releasing debian version ...'.
# * import commits, if any, are of the form 'Adding debian version ...'.
# * the repository has at least either of a release or an import commit on the
# target branch.
# * and finally, the target branch is including upstream sources, not just
# debianization. but that should be clear anyway.
