/**
 * Portable MySQL driver

 * @deprecated

 * Extends the deprecated mysql driver, and was originally designed to be a

 * is exactly duplicated in the mysqlt driver, which is itself deprecated.
 * This driver will be removed in ADOdb version 6.0.0.
 *
 * This file is part of ADOdb, a Database Abstraction Layer library for PHP.
