// archives stored as text - note these ar templated on the basic
// stream templates to accommodate wide (and other?) kind of characters
//
// 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<IStream::char_type> but rather
// use two template parameters
