  Set tabs to 8.

  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.
