#
# Run a group of kvm.sh tests on the specified commits.  This currently
# unconditionally does three-minute runs on each scenario in CFLIST,
# taking advantage of all available CPUs and trusting the "make" utility.
# In the short term, adjustments can be made by editing this script and
# CFLIST.  If some adjustments appear to have ongoing value, this script
# might grow some command-line arguments.
#
# Usage: kvm-check-branches.sh commit1 commit2..commit3 commit4 ...
#
# This script considers its arguments one at a time.  If more elaborate
# specification of commits is needed, please use "git rev-list" to
# produce something that this simple script can understand.  The reason
# for retaining the simplicity is that it allows the user to more easily
# see which commit came from which branch.
#
# This script creates a yyyy.mm.dd-hh.mm.ss-group entry in the "res"
# directory.  The calls to kvm.sh create the usual entries, but this script
# moves them under the yyyy.mm.dd-hh.mm.ss-group entry, each in its own
# directory numbered in run order, that is, "0001", "0002", and so on.
# For successful runs, the large build artifacts are removed.  Doing this
# reduces the disk space required by about two orders of magnitude for
# successful runs.
