 *
 * Note: this class is also used by format 'config'
 *
 * @param $data
 *   The $data parameter is rendered with the php var_export() function
 * @param $metadata
 *   'label' - If present, prints "$variable['label'] = " prior to the data
 *   'variable-name' - If present, provides an alternate name for $variable
 *     when labels are in use.
 *
 * Code:
 *
 *   return array(
 *     "a" => array("b" => 2, "c" => 3),
 *     "d" => array("e" => 5, "f" => 6)
 *   );
 *
 * Output with --format=var_export:
 *
 *   array (
 *     'a' =>
 *     array (
 *       'b' => 2,
 *       'c' => 3,
 *     ),
 *     'd' =>
 *     array (
 *       'e' => 5,
 *       'f' => 6,
 *     ),
 *   )
 *
 * Output with --format=config: (list of export)
 *
 *   $config['a'] = array (
 *     'b' => 2,
 *     'c' => 3,
 *   );
 *   $config['d'] = array (
 *     'e' => 5,
