+/**
+ * This plug-in for DataTables represents the ultimate option in extensibility
+ * for sorting date / time strings correctly. It uses
+ * [luxon](https://moment.github.io/luxon/) 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).
+ *
+ * @name Ultimate Date / Time sorting
+ * @summary Sort date and time in any format using luxon
+ * @author [Allan Jardine](//datatables.net)
+ * @depends DataTables 1.10+, luxon.js 1.0+
+ *
+ * @example
+ *    $.fn.dataTable.luxon( 'HH:mm MMM d, yy' );
+ *    $.fn.dataTable.luxon( 'EEE, MMMM Do, yyyy' );
+ *
+ *    $('#example').DataTable();
