This app is deprecated and mostly dead. It used to serve hacked-up console views for Buildbot.
These days, it only exists to run a mailer service used by Gatekeeper. When this is no longer required, this service should be turned down and deleted.
To deploy, just run:
./gae.py upload -A chromium-build
The uploaded version won‘t start serving production automatically; you’ll need to switch it over in the App Engine console.
