$description = "Test handling of double-colon rules.";

$details = "\
We test these features:

  - Multiple commands for the same (double-colon) target
  - Different prerequisites for targets: only out-of-date
    ones are rebuilt.
  - Double-colon targets that aren't the goal target.

Then we do the same thing for parallel builds: double-colon
targets should always be built serially.";

# TEST 0: A simple double-colon rule that isn't the goal target.
