"""
This package implements the GrampsDb database. It provides a number
of different backends for different storage mechanisms.

A number of importers and exporters are provided to convert between
the different backend formats.

To obtain a class that implements the backend required you should use the
gramps_db_factory method, likewise for writers use the gramps_db_writer_factory
method and for readers use the gramps_db_reader_factory method. For information
on using these factories see the _GrampsDbFactories.py file comments.

The package also contains GrampsDBCallback which provides signal/slot type
functionality to allow objects to hook into signals that are generated from
the database objects. Read the comments in _GrampsDBCallback.py for more
information.
