Initial commit of OpenSPARC T2 architecture model.

//
// SWIG typemaps for std::string
// Roy M. LeCates
// October 23, 2002
//
// Perl 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...
// ------------------------------------------------------------------------
