+# 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.

+# DESCRIPTION
+# This script is intended to be used in conjunction with "git bisect run"
+# in order to find regressions in build time, however it can also be used
+# independently. It cleans out the build output directories, runs a
+# specified worker script (an example is test_build_time_worker.sh) under
+# TIME(1), logs the results to TEST_LOGDIR (default /tmp) and returns a
+# value telling "git bisect run" whether the build time is good (under
+# the specified threshold) or bad (over it). There is also a tolerance
+# option but it is not particularly useful as it only subtracts the
+# tolerance from the given threshold and uses it as the actual threshold.
+#
+# It is also capable of taking a file listing git revision hashes to be
+# test-applied to the repository in order to get past build failures that
+# would otherwise cause certain revisions to have to be skipped; if a
+# revision does not apply cleanly then the script assumes it does not
+# need to be applied and ignores it.
+#
+# Please see the help output (syntax below) for some important setup
+# instructions.
+#
+# AUTHORS
