Abstract:

   NUp SAX handler definition. The class derives from the default SAX handler
   and implements only the necessary SAX APIs to process the mark-up. The
   handler is responsible for copying page mark-up to a writer, removing
   the fixed page opening and closing tags. It is also responsible for
   identifying resources that need to be copied from the source page to
   the NUp page.
