+ * jsmin.php - PHP implementation of Douglas Crockford's JSMin.
4
+ *
5
+ * This is a direct port of jsmin.c to PHP with a few PHP performance tweaks and
6
+ * modifications to preserve some comments (see below). Also, rather than using
7
+ * stdin/stdout, JSMin::minify() accepts a string as input and returns another
8
+ * string as output.
9
+ *
10
+ * Comments containing IE conditional compilation are preserved, as are multi-line
11
+ * comments that begin with "/*!" (for documentation purposes). In the latter case
12
+ * newlines are inserted around the comment to enhance readability.
13
+ *
14
+ * PHP 5 or higher is required.
15
+ *
