Added tag 10.3.3 for changeset cca465bf6a6a

"""
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.
