Upgrading to a new upstream release
-----------------------------------

1. Make sure that you clone the git repository, and then check out the
   debian/main branch.

2. Import upstream sources:

     git-import-orig --upstream-version=$version --sign-tags --pristine-tar $tar

3. Update debian changelog on the master branch:

     dch -v $version

   and commit.

4. Use git-debrebase for patch management.

5. Push all branches and tags.
