+# * the repository is using pristine-tar for non-native packages.
+# * 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.
