      1 # Ridiculously simple test of the os.startfile function for Windows.
      2 #
      3 # empty.vbs is an empty file (except for a comment), which does
      4 # nothing when run with cscript or wscript.
      5 #
      6 # A possible improvement would be to have empty.vbs do something that
      7 # we can detect here, to make sure that not only the os.startfile()
      8 # call succeeded, but also the the script actually has run.
