+/**
+ * JSMin.php - modified PHP implementation of Douglas Crockford's JSMin.
+ *
+ * <code>
+ * $minifiedJs = JSMin::minify($js);
+ * </code>
+ *
+ * This is a modified port of jsmin.c. Improvements:
+ *
+ * Does not choke on some regexp literals containing quote characters. E.g. /'/
+ *
+ * Spaces are preserved after some add/sub operators, so they are not mistakenly
+ * converted to post-inc/dec. E.g. a + ++b -> a+ ++b
+ *
+ * Preserves multi-line comments that begin with /*!
+ *
+ * PHP 5 or higher is required.
+ *
