Usage: megatest [options]
  -h                      : this help
  -manual                 : show the Megatest user manual
  -version                : print megatest version (currently " megatest-version ")
  help                    : help for the new Megatest interface

Launching and managing runs
  -run                    : run all tests or as specified by -testpatt
  -remove-runs            : remove the data for a run, requires -runname and -testpatt
                            Optionally use :state and :status, use -keep-records to remove only
                            the run data. Use -kill-wait to override the 10 second
                            per test wait after kill delay (e.g. -kill-wait 0). 

  -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
  -adjutant host-type     : start the server/adjutant with given host-type
                            use 0,0 to auto use full machine
  -transport http|rpc     : use http or rpc for transport (default is http) 
  -log logfile            : send stdout and stderr to logfile
  -list-servers           : list the servers 
  -kill-servers           : kill all servers
  -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 ...
  -debug-noprop N|M,M,O...: enable debug but do not propagate to subprocesses via MT_DEBUG
  -config fname           : override the megatest.config file with fname
  -append-config fname    : append fname to the megatest.config file
  -import-sexpr fname     : import a sexpr file (use -list-runs % -dumpmode sexpr to create)

  -regen-testfiles        : regenerate scripts and logpro files from testconfig, run in test context
  
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
