def system(cmd):
    """Win32 version of os.system() that works with network shares.

    Note that this implementation returns None, as meant for use in IPython.

    Parameters
    ----------
    cmd : str or list
      A command to be executed in the system shell.

    Returns
    -------
    None : we explicitly do NOT return the subprocess status code, as this
    utility is meant to be used extensively in IPython, where any return value
    would trigger :func:`sys.displayhook` calls.
