+All commits that are pushed to the central repository on Savannah must be
+signed with an OpenPGP key, and the public key should be uploaded to your user

+configure Git to automatically sign commits, run:
+
+ git config commit.gpgsign true
+ git config user.signingkey CABBA6EA1DC0FF33

+
+ cp etc/git/pre-push .git/hooks/pre-push

+This improves tracking of who did what.
