-:title: Tarmac Configuration
-
-Tarmac
-######
-
-Overview
-********
-
-Tarmac is a Patch Queue Manager written to manage and land merge requests in
-Launchpad. It is not integrated in to Jenkins, and therefore does not
-trigger Jenkins jobs to determine if a branch is good. Rather, Jenkins
-triggers tarmac on a periodic basis and tarmac checks the merge queue,
-performs its own tests on the branch, and either passes and merges the
-branch in question, or fails the branch, reports the error to the merge
-request and sets the status back to Work In Progress.
-
-Installation
-************
-
-Tarmac is installed from packages in the Tarmac PPA. It currently is
-installed and runs only on the Jenkins master.
-
-Install Tarmac PPA
-------------------
-::
-
-  add-apt-repository ppa:tarmac/ppa
-
-Install Tarmac
---------------
-::
-
-  apt-get install tarmac
-
-Configuration
-*************
-
-Tarmac keeps its config file in .config/tarmac/tarmac.conf in standard ini
-format. That config file is, in turn, stored in
-git://github.com/openstack/openstack-ci.git
-
-Authentication
-**************
-
-Tarmac authenticates to launchpad via oauth as the hudson-openstack user.
-
-Operation
-*********
-
-Tarmac is a command line program, which takes a subcommand and then a branch
-to land as arguments.
