.. class:: BsdDbShelf(dict[, protocol=None[, writeback=False]])
A subclass of :class:`Shelf` which exposes :meth:`first`, :meth:`next`,
- :meth:`previous`, :meth:`last` and :meth:`set_location` which are available in
- the :mod:`bsddb` module but not in other database modules. The *dict* object
- passed to the constructor must support those methods. This is generally
- accomplished by calling one of :func:`bsddb.hashopen`, :func:`bsddb.btopen` or
- :func:`bsddb.rnopen`. The optional *protocol* and *writeback* parameters have
- the same interpretation as for the :class:`Shelf` class.

Several builtin types such as :class:`list` and :class:`dict` do not directly
support weak references but can add support through subclassing::
