Jenkins, build.
Our build server is based on Jenkins (formally Hudson), and it is currently creating CentOS RPMs when changes are pushed to 1.8 and master. It is also building packages when requests for inspection requests. In the future, this will be integrated with our testing lab so we'll run tests as well.
