 :class:`numpy.DataSource` is a class which provides transparent decompression and remote file retrieval.
 :func:`numpy.genfromtxt` will handle this itself, however it will leave the downloaded files in the
 working directory, and opening explicitly allows you to use the file more directly as well.
