================
- new Plone sites will be created with a datetime suffix
which is helpful if you need to re-run new instances
over and over again e.g. for migration purposes. If you
need a fixed site id then explictely set the id using
the ``site-id`` option.

- Add buildout recipe option site-replace, defaults to
off. Use with ``site-id``.
New recipe option ``site-replace = on`` will remove any
existing object in app named ``site-id``. A new plone site
will be created to replace it.
Default option setting ``site-replace = off`` will not remove
existing objects in app named site-id.
