+/**
+ * Subscription Options
+ *
+ * A plugin which can enable or disable the use of imap subscriptions.
+ * It includes a toggle on the settings page under "Server Settings".
+ * The preference can also be locked
+ *
+ * Add it to the plugins list in config/main.inc.php to enable the user option
+ * The user option can be hidden and set globally by adding 'use_subscriptions'
+ * to the the 'dont_override' configure line:
+ * $rcmail_config['dont_override'] = array('use_subscriptions');
+ * and then set the global preference"
+ * $rcmail_config['use_subscriptions'] = true; // or false
+ *
+ * Roundcube caches folder lists.  When a user changes this option or visits
+ * their folder list, this cache is refreshed.  If the option is on the
+ * 'dont_override' list and the global option has changed, don't expect
+ * to see the change until the folder list cache is refreshed.
+ *
+ * @version 1.0
