// Contains the definition of the template codecvt_helper, useful for
// defining specializations of std::codecvt where state_type != mbstate_t.
// Compensates for the fact that some standard library implementations 
// do not derive the primiary codecvt template from locale::facet or 
// provide the correct member types and functions.

// Usage: 
//
// // In global namespace:
// BOOST_IOSTREAMS_CODECVT_SPEC(mystate)
//
// // In user namespace:
// template<typename Intern, typename Extern>
// struct mycodecvt : codecvt_helper<Intern, Extern, State> { ... };
//
// // Or:
// struct mycodecvt : codecvt_helper<wchar_t, char, State> { ... };
