Run data
  :runname                : required, name for this particular test run
  :state                  : required if updating step state; e.g. start, end, completed
  :status                 : required if updating step status; e.g. pass, fail, n/a

Values and record errors and warnings
  -set-values             : update or set values in the megatest db 
  :value                  : value measured
  :expected_value         : value expected
  :tol                    : tolerance |value-expect| <= tol
  :first_err              : record an error message
  :first_warn             : record a warning message

Queries
  -list-runs patt         : list runs matching pattern \"patt\", % is the wildcard
  -testpatt patt          : in list-runs show only these tests, % is the wildcard
  -itempatt patt          : in list-runs show only tests with items that match patt
  -showkeys               : show the keys used in this megatest setup

Misc 
  -force                  : override some checks
  -xterm                  : start an xterm instead of launching the test
  -remove-runs            : remove the data for a run, requires all fields be specified
                            and :runname ,-testpatt and -itempatt
                            and -testpatt
  -keepgoing              : continue running until no jobs are \"LAUNCHED\" or
                            \"NOT_STARTED\"
  -rerun FAIL,WARN...     : re-run if called on a test that previously ran (nullified
                            if -keepgoing is also specified)
  -rebuild-db             : bring the database schema up to date
  -rollup N               : fill run (set by :runname)  with latest test(s) from
                            past N days, requires keys
  -rename-run <runb>      : rename run (set by :runname) to <runb>, requires keys
  -update-meta            : update the tests metadata for all tests

Helpers
  -runstep stepname  ...  : take remaining params as comand and execute as stepname
                            log will be in stepname.log. Best to put command in quotes
  -logpro file            : with -exec apply logpro file to stepname.log, creates
                            stepname.html and sets log to same
                            If using make use stepname_logpro.log as your target
