  # Given the clearly documented use of annotated tags to signal releases,
  # it seems strange that there is no simple way to trigger actions if the
  # tag is annotated.  So we need to jump through some extra hoops.
  #
  # Looking at https://github.com/actions/checkout/issues/290 seems to show
  # that github just doesnt care about how git expects annotated tags to be
  # used.
  #
  # This workflow has added a `git fetch --force --tags` to every job that
  # needs to have working tags
