+
+# Principles of operation
+
+# - do not invoke dgit, anything involving any tarballs, no network
+# except `git push`
+
+# - do not look at the working tree, like `git push` `git tag`, and so
+# we can later add functionality to debpush any branch
+
+# - we are always in split brain mode, because this means the push won't
+# fail because dgit needs to append commits
+
+# - if there is no previous tag created by this script, require a quilt
+# mode; if there is a previous tag, and no quilt mode provided, assume
+# same quilt mode
+
+# Other notes (which should be converted to a manpage/usage)
+
+# - arguments after '--' passed to `git push`
+
+# ---- Helper functions
