Actions include:
   run                     : initial runs
   remove                  : remove runs
   rerun                   : register action for processing
   set-ss                  : set state/status
   archive                 : compress and move test data to archive disk
   kill                    : stop tests or entire runs
   process                 : master area only, process pkts, manage run jobs

Selectors 
  -immediate               : apply this action immediately, default is to queue up actions
  -area areapatt1,area2... : apply this action only to the specified areas
  -target key1/key2/...    : run for key1, key2, etc.
  -test-patt p1/p2,p3/...  : % is wildcard
  -run-name                : required, name for this particular test run
  -state-status c/p,c/f    : Specify a list of state and status patterns
  -mode-patt key           : load testpatt from <key> in runconfigs instead of default TESTPATT
                             if -testpatt and -tagexpr are not specified
