Drivers
=======

Drivers may support any of the following functions:

* Sources -- hosts git repositories for projects.  Zuul can clone git
  repos for projects and fetch refs.
* Triggers -- emits events to which Zuul may respond.  Triggers are
  configured in pipelines to cause changes or other refs to be
  enqueued.
* Reporters -- outputs information when a pipeline is finished
  processing an item.
* Providers -- manages build nodes in a cloud.
