Facebook - :mod:`velruse.providers.facebook`
============================================
The Facebook provider authenticates using the latest Facebook OAuth 2.0
API with the Social Graph API to obtain additional profile information
for use with user registration.
To use the Facebook authentication, you must register a Facebook application
for use with Velruse. You can do that by using the following links to learn about
and create said application. Once you have done so, you will be supplied with a
consumer key and a consumer secret specific to Facebook.
