 * SASL Password Driver
 *
 * Driver that adds functionality to change the users Cyrus/SASL password.
 * The code is derrived from the Squirrelmail "Change SASL Password" Plugin
 * by Galen Johnson.
 *
 * It only works with saslpasswd2 on the same host where RoundCube runs
 * and requires shell access and gcc in order to compile the binary.
 *
 * For installation instructions please read the README file.
 *
 * @version 1.0
