+Description: set version string to that of the git archive
+Author: Jon Dowland <jmtd@debian.org>
+Last-Update: 2011-12-05
+
+The upstream repo features these format strings in this file. The
+package "orig.tar.gz" file is created via "git archive" — which
+expands the format strings. Therefore, there is an immediate
+disparity between the orig.tar.gz contents and a bup checkout. In
+order to make building-from-repo and building-from-orig.tar the
+same, patch it back to the original state.
