# Usage:
#
#    tclsh soak1.tcl local-makefile.mk ?target? ?scenario?
#
# This generates many variations on local-makefile.mk (by modifing
# the OPT = lines) and runs them will fulltest, one by one.  The
# constructed makefiles are named "soak1.mk".
#
# If ?target? is provided, that is the makefile target that is run.
# The default is "fulltest"
#
# If ?scenario? is provided, it is the name of a single scenario to
# be run.   All other scenarios are skipped.
