- * jsmin.php - PHP implementation of Douglas Crockford's JSMin.
- *
- * This is pretty much a direct port of jsmin.c to PHP with just a few
- * PHP-specific performance tweaks. Also, whereas jsmin.c reads from stdin and
- * outputs to stdout, this library accepts a string as input and returns another
- * string as output.
- *
- * PHP 5 or higher is required.
- *
- * Permission is hereby granted to use this version of the library under the
- * same terms as jsmin.c, which has the following license:
