36 * This storage driver provides a mechanism for working through multiple

44 *     'type'    => <standard container type name>,
45 *     'options' => <normal array of options for container>,
46 *   ),
47 * );
48 *
49 * Full example:
50 *
51 * $options = array(
52 *   array(
53 *     'type'    => 'DB',
54 *     'options' => array(
55 *       'dsn' => "mysql://user:password@localhost/database",
56 *     ),
57 *   ),
58 *   array(
59 *     'type'    => 'Array',

61 *       'cryptType' => 'md5',
