    the logging module and would like to incorporate urlgrabber logging,
    then it can do so this way.  It's probably not necessary as most
    internal logging is only for debugging purposes.

    The passed-in object should be a logging.Logger instance.  It will
    be pushed into the keepalive and byterange modules if they're
    being used.  The mirror module pulls this object in on import, so
    you will need to manually push into it.  In fact, you may find it
    tidier to simply push your logging object (or objects) into each
    of these modules independently.
