Megatest

  -sort fieldname         : in -list-runs sort tests by this field

Misc 
  -start-dir path         : switch to this directory before running megatest
  -contour cname          : add a level of hierarcy to the linktree and run paths
  -rebuild-db             : bring the database schema up to date
  -cleanup-db             : remove any orphan records, vacuum the db
  -import-megatest.db     : push data from megatest.db to cache db files in /tmp/$USER
  -sync-to-megatest.db    : pull data from cache files in /tmp/$USER to megatest.db
  -sync-to dest           : sync to new postgresql central style database
  -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|rpc     : use http or rpc 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
  -debug N|N,M,O...       : enable debug 0-N or N and M and O ...
  -config fname           : override the megatest.config file with fname
  -append-config fname    : append fname to the megatest.config file

Utilities
  -env2file fname         : write the environment to fname.csh and fname.sh
  -envcap a               : save current variables labeled as context 'a' in file envdat.db
  -envdelta a-b           : output enviroment delta from context a to context b to -o fname
                            set the output mode with -dumpmode csh, bash or ini
                            note: ini format will use calls to use curr and minimize path
  -refdb2dat refdb        : convert refdb to sexp or to format specified by s-dumpmode
                            formats: perl, ruby, sqlite3, csv (for csv the -o param
                            will substitute %s for the sheet name in generating 
                            multiple sheets)
  -o                      : output file for refdb2dat (defaults to stdout)
  -archive cmd            : archive runs specified by selectors to one of disks specified
                            in the [archive-disks] section.
