Megatest

                            Optionally use :state and :status, use -keep-records to remove only
                            the run data.
  -set-state-status X,Y   : set state to X and status to Y, requires controls per -remove-runs
  -rerun FAIL,WARN...     : force re-run for tests with specificed status(s)
  -rerun-clean            : set all tests not COMPLETED+PASS,WARN,WAIVED to NOT_STARTED,n/a
                            and then run the specified testpatt with -preclean
  -rerun-all              : set all tests to NOT_STARTED,n/a and run with -preclean
  -redo-logpro            : do not rerun tests, but reapply logpro rules (ez-step flavor tests only)
  -redo-logpro            : do not rerun tests, but reapply logpro rules (ez-step flavor tests only; runs all tests unless -testpatt specified)
  -lock                   : lock run specified by target and runname
  -unlock                 : unlock run specified by target and runname
  -set-run-status status  : sets status for run to status, requires -target and -runname
  -get-run-status         : gets status for run specified by target and runname
  -run-wait               : wait on run specified by target and runname
  -preclean               : remove the existing test directory before running the test
  -clean-cache            : remove the cached megatest.config and runconfigs.config files
