Megatest

                            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


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

  -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 
  -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

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
