1. All run control access to db is direct.
2. All test machines must have megatest available
3. Tests may or may not have file system access to the originating
   run area. rsync is used to pull the test area to the home host
   if and only if the originating area can not be seen via file 
   system. NO LONGER TRUE. Rsync is used but file system must be visible.
4. All db access is done via the home host. NOT IMPLEMENTED YET.

Usage: megatest [options]

                            patterns.
  -list-disks             : list the disks available for storing runs
  -list-targets           : list the targets in runconfigs.config
  -list-db-targets        : list the target combinations used in the db
  -show-config            : dump the internal representation of the megatest.config file
  -show-runconfig         : dump the internal representation of the runconfigs.config file
  -dumpmode json          : dump in json format instead of sexpr
  -show-cmdinfo           : dump the command info for a test (run in test environment)

Misc 
  -rebuild-db             : bring the database schema up to date
  -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
  -transport http|zmq     : use http or zmq for transport (default is http) 
  -transport http|fs      : use http or direct access for transport (default is http) 
  -daemonize              : fork into background and disconnect from stdin/out
  -list-servers           : list the servers 
  -stop-server id         : stop server specified by id (see output of -list-servers)
  -repl                   : start a repl (useful for extending megatest)
  -load file.scm          : load and run file.scm
