      3 # Tests for combining the command line options -n (no action) and -t (touch).
      4 # This combination is unusual and probably doesn't ever happen in practice,
      5 # but still make needs to behave as expected.  The option -n is stronger than
      6 # -t, so instead of being touched, the commands of the targets are printed.
      7 #
      8 # See also:
      9 #	opt-touch-jobs.mk contains the same test without the option -n.
