"""Wrappers to get actually replaceable DBAPI2 compliant modules and
database connection whatever the database and client lib used.

Currently support:

- postgresql (pgdb, psycopg, psycopg2, pyPgSQL)
- mysql (MySQLdb)
- sqlite (pysqlite2, sqlite, sqlite3)

just use the `get_connection` function from this module to get a
wrapped connection.  If multiple drivers for a database are available,
you can control which one you want to use using the
`set_prefered_driver` function.

Additional helpers are also provided for advanced functionalities such
as listing existing users or databases, creating database... Get the
helper for your database using the `get_adv_func_helper` function.
