 * This file contains MERGED version of PHP QR Code library.
 * It was auto-generated from full version for your convenience.
 *
 * This merged version was configured to not requre any external files,
 * with disabled cache, error loging and weker but faster mask matching.
 * If you need tune it up please use non-merged version.
