This currently5# unconditionally does three-minute runs on each scenario in CFLIST,6# taking advantage of all available CPUs and trusting the "make" utility.7# In the short term, adjustments can be made by editing this script and8# CFLIST. If some adjustments appear to have ongoing value, this script9# might grow some command-line arguments.10#11# Usage: kvm-check-branches.sh commit1 commit2..commit3 commit4 ...12#13# This script considers its arguments one at a time. If more elaborate14# specification of commits is needed, please use "git rev-list" to15# produce something that this simple script can understand. The reason16# for retaining the simplicity is that it allows the user to more easily17# see which commit came from which branch.18#19# This script creates a yyyy.mm.dd-hh.mm.ss-group entry in the "res"20# directory. The calls to kvm.sh create the usual entries, but this script21# moves them under the yyyy.mm.dd-hh.mm.ss-group entry, each in its own22# directory numbered in run order, that is, "0001", "0002", and so on.23# For successful runs, the large build artifacts are removed. Doing this24# reduces the disk space required by about two orders of magnitude for25# successful runs.26#27# Copyright (C) Facebook, 202028#29# Authors: Paul E.
