The BuildBot is a system to automate the compile/test cycle required by most 
software projects to validate code changes. By automatically rebuilding and 
testing the tree each time something has changed, build problems are pinpointed 
quickly, before other developers are inconvenienced by the failure. The guilty 
developer can be identified and harassed without human intervention. By running 
the builds on a variety of platforms, developers who do not have the facilities 
to test their changes everywhere before checkin will at least know shortly 
afterwards whether they have broken the build or not. Warning counts, lint 
checks, image size, compile time, and other build parameters can be tracked 
over time, are more visible, and are therefore easier to improve.

See also buildbot-slave (the slave component of BuildBot).
