 We also need to update the version numbers in the man pages. For that
 we download the release tar ball and generate a diff:
 #+begin_src shell
-  diff -ru . /home/florian/nsd-4.7.0/ | fgrep -v Only > sync.diff
+  diff -bru . /home/florian/nsd-4.7.0/ | fgrep -v Only > sync.diff
 #+end_src
 The diff then needs to be partially applied, some changes are
 intentional.
