+ * Virtualmin Password Driver
+ *
+ * Driver that adds functionality to change the users Virtualmin password.
+ * The code is derrived from the Squirrelmail "Change Cyrus/SASL Password" Plugin
+ * by Thomas Bruederli.
+ *
+ * It only works with virtualmin on the same host where Roundcube runs
+ * and requires shell access and gcc in order to compile the binary.
+ *
+ * @version 3.0
