 * This command line script rips gettext strings from smarty file,
 * and prints them to stdout in C format, that can later be used with the
 * standard gettext tools.
 *
 * Usage:
 * ./tsmarty2c.php <filename or directory> <file2> <..> > smarty.c
 *
 * If a parameter is a directory, the template files within will be parsed.
 *
 * @package    smarty-gettext
