#    Check the PyPI listing page to make sure that the README, release notes, and roadmap display properly. If not, copy and paste the RestructuredText into http://rst.ninjs.org/ to find out what broke the formatting.
#    Edit the release on GitHub (e.g. https://github.com/audreyr/cookiecutter/releases). Paste the release notes into the release's release page, and come up with a title for the release.
