      5 We test these features:
      6 
      7   - Multiple commands for the same (double-colon) target
      8   - Different prerequisites for targets: only out-of-date
      9     ones are rebuilt.
     10   - Double-colon targets that aren't the goal target.
     11 
     12 Then we do the same thing for parallel builds: double-colon
     13 targets should always be built serially.";
