  -set-values             : update or set values in the testdata table
  :category               : set the category field (optional)
  :variable               : set the variable name (optional)

  -load-test-data         : read test specific data for storage in the test_data table
                            from standard in. Each line is comma delimited with four
                            fields category,variable,value,comment

Queries
  -list-runs patt         : list runs matching pattern \"patt\", % is the wildcard
  -showkeys               : show the keys used in this megatest setup
  -test-path targpatt    : get the most recent test path(s) matching targpatt e.g. %/%... 
                            returns list sorted by age ascending, see examples below

Misc 
  -rebuild-db             : bring the database schema up to date
  -update-meta            : update the tests metadata for all tests
  -env2file fname         : write the environment to fname.csh and fname.sh
  -setvars VAR1=val1,VAR2=val2 : Add environment variables to a run NB// these are
                                 overwritten by values set in config files.
  -server -|hostname      : start the server (reduces contention on megatest.db), use
                            - to automatically figure out hostname
  -repl                   : start a repl (useful for extending megatest)

Spreadsheet generation
  -extract-ods fname.ods  : extract an open document spreadsheet from the database
  -pathmod path           : insert path, i.e. path/runame/itempath/logfile.html
                            will clear the field if no rundir/testname/itempath/logfile
                            if it contains forward slashes the path will be converted
                            to windows style
