<<-INFO
The User Klout Influence module can be used to gather an influence graph of all
users in the currently active workspace. The Klout Influence API can tell who
users are being influenced by as well as who they are influencing.

The influence graph can be generated with the #{'users/influence_graph'.bold} module
when the raw data has been gathered with this module.

#{'Note:'.bold} This module requires that users have been enriched with their
Klout ID from the #{'users/klout_id'.bold} module. It also requires that Birdwatcher has
been configured with one or more Klout API keys in order to work.
