According to the wiki I do this with the following command:
brian@prune:~/tree/debian/python-modules/django-ajax-selects$ git-dpm tag
git-dpm: ERROR: tag 'upstream/1.3.6' already exists and differs!
This wasn't the response I was expecting. I am not sure why it is trying to change the upstream tag, or what it is trying to change it to. Should I just create the debian/1.3.6-4 tag manually?
