  -section sectionName
  -var varName            : for config and runconfig lookup value for sectionName varName

Misc 
  -start-dir path         : switch to this directory before running megatest
  -rebuild-db             : bring the database schema up to date
  -cleanup-db             : remove any orphan records, vacuum the db
  -import-megatest.db     : migrate a database from v1.55 series to v1.60 series
  -sync-to-megatest.db    : migrate data back to megatest.db
  -update-meta            : update the tests metadata for all tests
  -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|fs      : use http or direct access for transport (default is http) 
  -transport http|zmq     : use http or zmq for transport (default is http) 
  -daemonize              : fork into background and disconnect from stdin/out
  -log logfile            : send stdout and stderr to logfile
  -list-servers           : list the servers 
  -stop-server id         : stop server specified by id (see output of -list-servers), use
                            0 to kill all
  -repl                   : start a repl (useful for extending megatest)
  -load file.scm          : load and run file.scm
  -mark-incompletes       : find and mark incomplete tests
  -ping run-id|host:port  : ping server, exit with 0 if found

Utilities
  -env2file fname         : write the environment to fname.csh and fname.sh
  -refdb2dat refdb        : convert refdb to sexp or to format specified by -dumpmode
                            formats: perl, ruby, sqlite3
  -o                      : output file for refdb2dat (defaults to stdout)
  -archive targdir        : archive runs specified by selectors to targdir using bup

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
