// SWIG typemaps for std::string
// Luigi Ballabio
// Apr 8, 2002
//
// Ruby implementation
// ------------------------------------------------------------------------
// std::string is typemapped by value
// This can prevent exporting methods which return a string
// in order for the user to modify it.
// However, I think I'll wait until someone asks for it...
// ------------------------------------------------------------------------
