|RCX|
-----

|RCX| add additional functionality for push/pull/create/delete |repo| hooks.
These hooks can be used to send signals to build-bots such as `Jenkins`_. It
also adds built in plugin and extension support. Once installed, you will see
a :file:`rcextensions` folder in the instance directory, for example:
:file:`home/{user}/.rccontrol/{instance-id}/rcextensions`

Built-in Plugins

  tracker: ``extract_redmine_issues.py``, ``redmine_pr_flow.py``,

  `HipChat`_ and set channel or user notifications.

Event Listeners
^^^^^^^^^^^^^^^

To enable the extensions to listen to the different events that they are
configured for, you need to also set up an event listener (hook). Event
listeners are configured in the
:file:`/home/{user}/.rccontrol/{instance-id}/rcextensions/__init.__.py` file.

For more details, see the example hook in :ref:`event-listener`.
