        `gnarails new NAME` will create a new rails application called NAME,
        pre-built with the same helpful default configuration you can expect from
        any rails project built by The Gnar Company.

        By default, we pass arguments to `rails new` that skip test unit
        generation and use postgres instead of sqlite as the default database.

        You should also be able to pass any other arguments you would expect to
        be able to when generating a new rails app.
