+.. option:: --sort=(newest-first|oldest-first)
+
+ This option can be used to present results in either chronological
+ order (**oldest-first**) or reverse chronological order
+ (**newest-first**).
+
+ Only threads as a whole are reordered. Ordering of messages within
+ each thread will not be affected by this flag, since that order is
+ always determined by the thread's replies.
+
+ By default, results will be displayed in reverse chronological
+ order, (that is, the newest results will be displayed first).
