Buildbot:
Buildbot is a job scheduling system: it queues jobs, executes the jobs when the required resources are available, and reports the results.
Your Buildbot installation has one or more masters and a collection of slaves. The masters monitor source-code repositories for changes, coordinate the activities of the slaves, and report results to users and developers. Slaves run on a variety of operating systems.
