+ * DBMail Password Driver
+ *
+ * Driver that adds functionality to change the users DBMail password.
+ * The code is derrived from the Squirrelmail "Change SASL Password" Plugin
+ * by Galen Johnson.
+ *
+ * It only works with dbmail-users 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
