   @brief     Example of how to use QUEUEs in the STL specified by C++ 98 .@EOL
   @Keywords  Standard C++ I/O character string iostream STL queue template
   @Std       C++98

              This program is an example of how use the queue template
              in the STL of C++ 98.  The queue template an adapter
              that will transform any conainer supporting front(),
              back(), push_back(), and pop_front() into a FIFO stack
              supporting front(), back(), push(), and pop().  Note
              that queues support empty() and size() too.
