    # You should see a semi-steady stream of printouts signaling the current package
    # the algorithm is processing, and the amount of packages (including dependencies)
    # its seen so far.

    #
    # Upon completion of the generation, you should see a file 'test_packages.csv' in the

    # is in the same format.
