  -load-test-data         : read test specific data for storage in the test_data table
                            from standard in. Each line is comma delimited with four

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