    # A dump task to print application results to a file or IO.  The results are
    # printed in a format allowing dumped results to be reloaded and used as
    # inputs to other tasks.  See Tap::Load for more details.
    #
    # Often dump is used as the final task in a round of tasks; if no filepath is 
    # specified, the results are printed to stdout.
