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]

                            Optionally use :state and :status
  -set-state-status X,Y   : set state to X and status to Y, requires controls per -remove-runs
  -rerun FAIL,WARN...     : force re-run for tests with specificed status(s)
  -rollup                 : (currently disabled) fill run (set by :runname)  with latest test(s)
                            from prior runs with same keys
  -lock                   : lock run specified by target and runname
  -unlock                 : unlock run specified by target and runname
  -run-wait               : wait on run specified by target and runname

Selectors (e.g. use for -runtests, -remove-runs, -set-state-status, -list-runs etc.)
  -target key1/key2/...   : run for key1, key2, etc.
  -reqtarg key1/key2/...  : run for key1, key2, etc. but key1/key2 must be in runconfig
  -testpatt patt1/patt2,patt3/...  : % is wildcard
  :runname                : required, name for this particular test run
  :state                  : Applies to runs, tests or steps depending on context

  :units                  : name of the units for value, expected_value etc. (optional)
  -load-test-data         : read test specific data for storage in the test_data table
                            from standard in. Each line is comma delimited with four
                            fields category,variable,value,comment

Queries
  -list-runs patt         : list runs matching pattern \"patt\", % is the wildcard
  -showkeys               : show the keys used in this megatest setup
  -test-files targpatt     : get the most recent test path/file matching targpatt e.g. %/%... 
  -show-keys              : show the keys used in this megatest setup
  -test-files targpatt    : get the most recent test path/file matching targpatt e.g. %/%... 
                            returns list sorted by age ascending, see examples below
  -test-paths             : get the test paths matching target, runname, item and test
                            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|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
