+# DESCRIPTION
+# This script runs BB_CMD (typically building core-image-sato) for all
+# combincations of BB_RANGE and PM_RANGE values. It saves off all the console
+# logs, the buildstats directories, and creates a bb-pm-runtime.dat file which
+# can be used to postprocess the results with a plotting tool, spreadsheet, etc.
+# Before running this script, it is recommended that you pre-download all the
+# necessary sources by performing the BB_CMD once manually. It is also a good
+# idea to disable cron to avoid runtime variations caused by things like the
+# locate process. Be sure to sanitize the dat file prior to post-processing as
+# it may contain error messages or bad runs that should be removed.
