 .. 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.
