 The regex '\/$' should be used to match directory nodes.
 
+A special flag can be used to sort by the modification timestamps of files and
+directories. It is either '[[timestamp]]' for ascending, or '[[-timestamp]]'
+for descending. If placed at the beginning of the list, files and directories
+are sorted by timestamp, and then by the remaining items in the sort order
+list. If this flag is in any other position of the list, timestamp sorting is
+done secondarily. See examples 4, 5, and 6 below.

 After this sorting is done, the files in each group are sorted alphabetically.
 
 Other examples: >
     (1) ['*', '\/$']
     (2) []
