In Ubuntu, we will use MAJOR.MINOR for the policy version, ignoring MICRO.
Therefore, this package uses a version number of 15.04 for the initial release
and ships policy in ubuntu-core/15.04. The 15.04.1 release will make changes to
ubuntu-core/15.04 while 15.10 will start shipping policy for ubuntu-core/15.10.

When creating a new major/minor version, use debian/make-new-version.sh. Eg,
to create the 15.10 policy based on 15.04. do:
$ sh ./debian/make-new-version.sh 15.04 15.10

This will create the necessary directories then symlink all entries from the
previous version to this one. Note: MAJOR.MINOR must form a positive decimal
number compatible with the JSON Number type.

When adding templates and policy groups, you should also adjust the
debian/tests/installed_* autopkgtest scripts. This should also be done when
adding new policy groups and templates.
