+ * This plug-in for DataTables represents the ultimate option in extensibility
+ * for sorting date / time strings correctly. It uses
+ * [Moment.js](http://momentjs.com) to create automatic type detection and
+ * sorting plug-ins for DataTables based on a given format. This way, DataTables
+ * will automatically detect your temporal information and sort it correctly.
+ *
+ * For usage instructions, please see the DataTables blog
+ * post that [introduces it](//datatables.net/blog/2014-12-18).
