+      The Tar program provides the ability to create tar archives, as
+      well as various other kinds of manipulation.  For example, you
+      can use Tar on previously created archives to extract files, to
+      store additional files, or to update or list files which were
+      already stored.
+
+      Initially, tar archives were used to store files conveniently on
+      magnetic tape.  The name "Tar" comes from this use; it stands
+      for tape archiver.  Despite the utility's name, Tar can direct
+      its output to available devices, files, or other programs (using
+      pipes), it can even access remote devices or files (as
+      archives).
