+Sometimes upstream does not tag their releases, or you want to package
+an unreleased git snapshot.  In such a case you can create your own
+upstream release tag, of the form B<upstream/>I<ver>, where I<ver> is
+the upstream version you plan to put in I<debian/changelog>.  The
+B<upstream/> prefix ensures that your tag will not clash with any tags
+upstream later creates.
+
+For example, suppose that the latest upstream release is 1.2.2 and you
+want to package git commit ab34c21 which was made on 2013-12-11.  A
+common convention is to use the upstream version number
+1.2.2+git20131211.ab34c21 and so you could use
