  -version                : print megatest version (currently " megatest-version ")

  -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)
  -load file.scm          : load and run file.scm

Spreadsheet generation
