        This is a convenience method for downloading a file from an URL.
        Normally, this will be a file from the index, though currently
        no check is made for this (i.e. a file can be downloaded from
        anywhere).

        The method is just like the :func:`urlretrieve` function in the
        standard library, except that it allows digest computation to be
        done during download and checking that the downloaded data
        matched any expected value.

        :param url: The URL of the file to be downloaded (assumed to be
                    available via an HTTP GET request).
        :param destfile: The pathname where the downloaded file is to be
                         saved.
        :param digest: If specified, this must be a (hasher, value)
                       tuple, where hasher is the algorithm used (e.g.
                       ``'md5'``) and ``value`` is the expected value.
        :param reporthook: The same as for :func:`urlretrieve` in the
                           standard library.
