+The master script in this folder is build-all (written in Python)
+which will setup and control the whole process. The other scripts
+(using bash) are launched from build-all either to do specific tasks
+locally, or to run on each individual build machine to manage the
+build process there, usually by calling out to other scripts that
+already exist. The build-all script uses the taskrunner.py and
+subprocess Python modules.
