## view.py
    p = Paginator(mylist, settings.PAGE_NUM)
    try:
        page = int(request.GET.get('page', '1'))
        cp = p.page(page)
    except  InvalidPage:
        raise Http404
    return HttpResponse(MakoTemplate(templatename="bulletin.htm",
                                     current_page=cp,
                                     totalpage=p.num_pages,
                                     currentpage=page,
                                     ))
