 category:        Codec
 synopsis:        Command-line tar archive utility.
 description:     A Command-line utility to create, extract and list the
                  contents of tar archives. It can work with compressed
                  archives using gzip or bzip2 compression.
+                 .
+                 This is in part a demo of the @tar@ library but it is also
+                 usable in place of the ordinary @tar@ program for systems
+                 like Windows that do not come with it as standard.
