+ * useful if your Drupal installation exists in a schema that is not the default
+ * or you want to access several databases from the same code base at the same

+ * Example:
+ *
+ *  $db_prefix = array(
+ *    'default' => 'main.',
+ *     'users'      => 'shared.',
+ *     'sessions'  => 'shared.',
+ *     'role'      => 'shared.',
+ *     'authmap'   => 'shared.',
+ *  );

  *   $databases['default']['default'] = array(
  *     'driver' => 'mysql',
