// The standard t_output_helper has been changed to return a list rather than
// a tuple, we'll replace it with the old implementation here.  In SWIG 1.3.27
// and earlier it is implemented as a $fragment, so it is only inserted into
// the modules that need it.  For SWIG 1.3.28+ we just need to add a -D on the
// compile command line to turn on the tuple version of the AppendOuput
// function.
