+ * 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:
