MySQLdb
=======
A DB API v2.0 compatible interface to MySQL
-------------------------------------------
This package is a wrapper around _mysql, which mostly implements the
MySQL C API.
See the C API specification and the MySQL documentation for more info
on other items.
For information on the DB API, see PEP-249.
For information on how MySQLdb handles type conversion, see the
MySQLdb.converters module.
