Every time this field is displayed * the field must be preceded with "Produced " (P) " ", where (P) is one * character showing a P in a circle. * * @package php-reader * @subpackage ID3 * @author Sven Vollbehr * @copyright Copyright (c) 2008 The PHP Reader Project Workgroup * @license http://code.google.com/p/php-reader/wiki/License New BSD License * @version $Rev: 65 $ * @since ID3v2.4.0 */ final class ID3_Frame_TPRO extends ID3_Frame_AbstractText {}
