* DESCRIPTION:
* ------------------------------------------------------------------------
* This library tells the PHP4 session handler to write to a MySQL database
* instead of creating individual files for each session.
*
* Create a new database in MySQL called "sessions" like so:
*
* CREATE TABLE `sessions` (
* `sesskey` varchar(32) NOT NULL default '',
* `expiry` int(11) unsigned NOT NULL default '0',
* `lastused` timestamp(14) NOT NULL,
* `value` text NOT NULL,
* PRIMARY KEY `sesskey` (`sesskey`),
* );
*
* ------------------------------------------------------------------------
* USAGE:
* ------------------------------------------------------------------------
* Include this file in your scripts before you call session_start(), you
* don't have to do anything special after that.
