code: def runProcess(cmd, *args):
      
      from os import spawnvp, P_WAIT
      return spawnvp(P_WAIT, cmd, (cmd,) + args)
docs: Run `cmd` (which is searched for in the executable path) with `args` and
      return the exit status.
  
      In general (unless you know what you're doing) use::
  
       runProcess('program', filename)
  
      rather than::
  
       os.system('program %s' % filename)
  
      because the latter will not work as expected if `filename` contains
      spaces or shell-metacharacters.
  
      If you need more fine-grained control look at ``os.spawn*``.
