+The Debian packaging of $source is maintained using dgit.  For the
+sake of an efficient workflow, Debian modifications to the upstream
+source are squashed into a single diff, rather than a series of quilt
+patches.  To obtain a patch queue for package version 1.2.3-1:
+
+    # apt-get install dgit
+    % dgit clone $source
+    % cd $source
+    % git log --oneline 1.2.3..debian/1.2.3-1 -- . ':!debian'
+
+See dgit(1), dgit(7) and dgit-maint-merge(7) for more information.
