// archives stored as text - note these ar templated on the basic

// note the fact that on libraries without wide characters, ostream is
// is not a specialization of basic_ostream which in fact is not defined
// in such cases.   So we can't use basic_ostream<OStream::char_type> but rather
// use two template parameters
