+ * This plug-in will provide date sorting for the "dd/mm/YYYY hh:ii:ss" 
+ * formatting, which is common in France and other European countries. It can 
+ * also be quickly adapted for other formatting as required. Furthermore, this 
+ * date sorting plug-in allows for empty values in the column.
+ *
+ * Please note that this plug-in is **deprecated*. The
+ * [datetime](//datatables.net/blog/2014-12-18) plug-in provides enhanced
+ * functionality and flexibility.
