OAuth 2.0 client library
oauth2client is a client library for OAuth 2.0.
Note: oauth2client is now deprecated. No more features will be added to the
libraries and the core team is turning down support. We recommend you use
google-auth <https://google-auth.readthedocs.io>

oauthlib <http://oauthlib.readthedocs.io/>
