Megatest

  -rollup                 : fill run (set by :runname)  with latest test(s) from
                            prior runs with same keys
  -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.
  -archive                : archive tests, use -target, :runname, -itempatt and -testpatt
  -server                 : start the server (reduces contention on megatest.db)
  -server -|hostname      : start the server (reduces contention on megatest.db), use
                            - to automatically figure out hostname

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
