Documentation about each of the chromeOS autotest infrastructure components can
be found here. The components are grouped into 2 categories: those that are
"core" pieces of the infrastructure, such as the scheduler, dev servers, and
results database; and those that are "auxiliary" pieces of infrastructure, such
as monitoring and bug-filing systems.
