Launching and managing runs
  -run                    : run all tests or as specified by -testpatt
  -remove-runs            : remove the data for a run, requires -runname and -testpatt
                            Optionally use :state and :status
  -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
  -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
  -no-cache               : do not use the cached config files. 

Selectors (e.g. use for -runtests, -remove-runs, -set-state-status, -list-runs etc.)
  -target key1/key2/...   : run for key1, key2, etc.
  -reqtarg key1/key2/...  : run for key1, key2, etc. but key1/key2 must be in runconfigs
  -testpatt patt1/patt2,patt3/...  : % is wildcard
  -runname                : required, name for this particular test run
  -state                  : Applies to runs, tests or steps depending on context
  -status                 : Applies to runs, tests or steps depending on context
  --modepatt key          : load testpatt from <key> in runconfigs instead of default TESTPATT if -testpatt and -tagexpr are not specified
  -tagexpr tag1,tag2%,..  : select tests with tags matching expression

  -test-paths             : get the test paths matching target, runname, item and test
                            patterns.
  -list-disks             : list the disks available for storing runs
  -list-targets           : list the targets in runconfigs.config
  -list-db-targets        : list the target combinations used in the db
  -show-config            : dump the internal representation of the megatest.config file
  -show-runconfig         : dump the internal representation of the runconfigs.config file
  -dumpmode MODE          : dump in MODE format instead of sexpr, MODE=json,ini,sexp etc. (add -debug 0,9 to see which file contributes each line)
  -show-cmdinfo           : dump the command info for a test (run in test environment)
  -section sectionName
  -var varName            : for config and runconfig lookup value for sectionName varName
  -since N                : get list of runs changed since time N (Unix seconds)
  -fields fieldspec       : fields to include in json dump; runs:id,runame+tests:testname+steps
  -sort fieldname         : in -list-runs sort tests by this field

Misc 
  -start-dir path         : switch to this directory before running megatest

  -rebuild-db             : bring the database schema up to date
  -cleanup-db             : remove any orphan records, vacuum the db

                                 overwritten by values set in config files.
  -server -|hostname      : start the server (reduces contention on megatest.db), use
                            - to automatically figure out hostname
  -transport http|rpc     : use http or rpc for transport (default is http)

  -envdelta a-b           : output enviroment delta from context a to context b to -o fname
                            set the output mode with -dumpmode csh, bash or ini
                            note: ini format will use calls to use curr and minimize path
  -refdb2dat refdb        : convert refdb to sexp or to format specified by s-dumpmode
                            formats: perl, ruby, sqlite3, csv (for csv the -o param
                            will substitute %s for the sheet name in generating 
                            multiple sheets)
  -o                      : output file for refdb2dat (defaults to stdout)
  -archive cmd            : archive runs specified by selectors to one of disks specified
                            in the [archive-disks] section.
