+ * Rackspace extends the OpenStack class with support for Rackspace's
+ * API key and tenant requirements.
+ *
+ * The only difference between Rackspace and OpenStack is that the
+ * Rackspace class generates credentials using the username
+ * and API key, as required by the Rackspace authentication
+ * service.
+ *
+ * Example:
+ * <code>
+ * $username = 'FRED';
+ * $apiKey = '0900af093093788912388fc09dde090ffee09';
+ * $conn = new Rackspace(
+ *      'https://identity.api.rackspacecloud.com/v2.0/',
+ *      array(
+ *          'username' => $username,
+ *          'apiKey' => $apiKey
+ *      ));
+ * </code>
