 2    When checked, Hudson simply aggregates tests from
 3    all the transitive downstream jobs of this project. This is convenient
 4    as you don't have to individually list them and keep them up to date
 5    as you add/remove jobs. This normally works just fine, as your test
 6    jobs are normally set up as downstream jobs of the build job.

 9    If for some reasons the auto aggregation doesn't work, you can always
10    manually specify a list of jobs to be aggregated.
