<   MySQL code that supports transactions. For MySQL 3.23 or later.
<   Code from James Poon <jpoon88@yahoo.com>
< 
<   This driver extends the deprecated mysql driver, and was originally designed to be a
<   portable driver in the same manner as oci8po and mssqlpo. Its functionality
<   is exactly duplicated in the mysqlt driver, which is itself deprecated.
<   This driver will be removed in ADOdb version 6.0.0.
< 
<   Requires mysql client. Works on Windows and Unix.
