+#!/usr/bin/env python
+"""
+This script takes `minimumhgversion` and `testedwith` values from the first
+file (e.g. hgext3rd/evolve/metadata.py) and mercurial package versions from the
+second file (e.g. debian/control) and compares them using a set of rules to
+find any issues.
+
+Rules:
+
+    - if `minimumhgversion` is a feature release, the first version from
+      `testedwith` should belong to that feature release
+
+    - if `minimumhgversion` is a bugfix release, the first version from
+      `testedwith` should be the same
+
+    - mercurial package versions (from both Depends and Build-Depends sections)
+      should match `minimumhgversion`
+
+Usage: $0 MFILE CFILE where MFILE contains extension metadata and CFILE is a
+debian/control file.
