Zope.generations

==================

- Removed buildout part which was used during development but does not
compile on Windows.

- Generation scripts add a transaction note.

==================

- Initial release extracted from ``zope.app.generations``.

- Generations key (stored in database root) has been changed from
``zope.app.generations`` to ``zope.generations``. Migration is done when
``evolve`` is run the first time by coping the existing generations data
over to the new key. So the old and the new key can be used in parallel.
