Megatest

  -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
  -transport http|zmq     : use http or zmq for transport (default is http) 
  -list-servers           : list the servers 
  -repl                   : start a repl (useful for extending megatest)
  -load file.scm          : load and run file.scm

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
