        `nose console` gives a convenient way to perform manual exploration of

        generated plan data. It will load plans from the given file and then

        define a number of variables containing this data. This includes all

        instance variables in the `Search::Results` object as well as the

        `model` used to generate the results, the `options` loaded from the

        configuration file, and an instance of the configured `backend`.
