    # The algorithm below takes advantage of the fact that once we've determined that there is more than one file
    # that's different, or if the first item returned by the generator is not the sitemap, then we can break out of
    # the generator loop early. This is also advantageous because it doesn't require us to completely exhaust the
    # generator. In the case of a fresh site build, for example, the generator will return a lot more data. So the
    # other approach here of expanding the generator into a list with a list comprehension would be inefficient
    # in many cases. This approach performs equally well in all cases at the cost of some unusual-looking code.
