+/**
+ * jsmin.php - PHP implementation of Douglas Crockford's JSMin.
+ *
+ * This is a direct port of jsmin.c to PHP with a few PHP performance tweaks and
+ * modifications to preserve some comments (see below). Also, rather than using
+ * stdin/stdout, JSMin::minify() accepts a string as input and returns another
+ * string as output.
+ *
+ * Comments containing IE conditional compilation are preserved, as are multi-line
+ * comments that begin with "/*!" (for documentation purposes). In the latter case
+ * newlines are inserted around the comment to enhance readability.
+ *
+ * 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:
+ *
