Detailed Description
   template<typename _CharT>
       class std::messages< _CharT >"Primary class template messages.

       This facet encapsulates the code to retrieve messages from message
       catalogs. The only thing defined by the standard for this facet is the
       interface. All underlying functionality is implementation-defined.

       This library currently implements 3 versions of the message facet. The
       first version (gnu) is a wrapper around gettext, provided by libintl.
       The second version (ieee) is a wrapper around catgets. The final
       version (default) does no actual translation. These implementations are
       only provided for char and wchar_t instantiations.

       The messages template uses protected virtual functions to provide the
       actual results. The public accessors forward the call to the virtual
       functions. These virtual functions are hooks for developers to
       implement the behavior they require from the messages facet.

Constructor & Destructor Documentation
   template<typename _CharT > std::messages< _CharT >::messages (size_t __refs
       = 0) [explicit]
       Constructor performs initialization. This is the constructor provided
       by the standard.

       Parameters
           __refs Passed to the base facet class.

   template<typename _CharT > std::messages< _CharT >::messages (__c_locale
       __cloc, const char * __s, size_t __refs = 0) [explicit]
       Internal constructor. Not for general use. This is a constructor for
       use by the library itself to set up new locales.

       Parameters
           __cloc The C locale.
           __s The name of a locale.
           __refs Refcount to pass to the base class.

   template<typename _CharT > std::messages< _CharT >::~messages ()
       [protected],  [virtual]
       Destructor.
