- * The object model of DB is as follows (indentation means inheritance):

- * DB           The main DB class.  This is simply a utility class
- *              with some "static" methods for creating DB objects as
- *              well as common utility functions for other DB classes.
- *
- * DB_common    The base for each DB implementation.  Provides default
- * |            implementations (in OO lingo virtual methods) for
- * |            the actual DB implementations as well as a bunch of
- * |            query utility functions.
- * |
- * +-DB_mysql   The DB implementation for MySQL.  Inherits DB_common.
- *              When calling DB::factory or DB::connect for MySQL
- *              connections, the object returned is an instance of this
