//
// Description: Provides <tchar.h> like string abstraction for
// C++ std::string and related IO stream classes.
//
// For detailed information on the C++ Standard Library string,
// iostream and stringstream classes, see the book 
// "C++ Standard Library", by Nicolai Josuttis.
//
// This file is intended to extend the ideas embodied in <tchar.h>
// to the C++ standard library classes and streams.
//
// Provides:
//  rt::tstring
//  rt::tistringstream, rt::tostringstream, rt::tstringstream
//  rt::tistream,       rt::tostream,       rt::tiostream
//  rt::tifstream,      rt::tofstream,      rt::tfstream
//
//  tcin, tcout, tcerr, tclog
