This plugin adds a gist reStructuredText directive. Eg:
.. gist:: ionelmc/eb11afbcca187bad5273 setup.py python
It will download (with cache) and include the gist contents in the document.
Note
It also supports embedding content from github directly.
Example, to include https://raw.githubusercontent.com/ionelmc/cookiecutter-pylibrary/master/%7B%7Bcookiecutter.repo_name%7D%7D/setup.py:
.. github:: ionelmc/cookiecutter-pylibrary master/{{cookiecutter.repo_name}}/setup.py
