fdb is a kinterbasdb compatible DBAPI for Firebird.
.. versionadded:: 0.8 - Support for the fdb Firebird driver.
.. versionchanged:: 0.9 - The fdb dialect is now the default dialect
under the ``firebird://`` URL space, as ``fdb`` is now the official
Python driver for Firebird.
The dialect currently accepts the same arguments as the Kinterbasdb driver.
