Sage has two build bots.
The first builds entire tarballs (e.g. all the development releases) on a wide variety of machines. It can be found at http://build.sagemath.org/sage/ .
Patch Buildbot (Patchbot)
The second pulls and applies git branches from Trac and can be found at http://patchbot.sagemath.org/ or from links on the individual Trac tickets (round icons at top right).
You can help by running your own patchbot. See this instruction page for installation and usage.
This is still very much a work in progress; the latest version of the code lives at http://github.com/robertwb/sage-patchbot. Eventually this will get moved into Sage where it can be edited using the standard procedures and more widely deployed. See ticket http://trac.sagemath.org/sage_trac/ticket/12486.
