JD,
The '+' operator is looked up in a three dimensional array of op x type x type.
You will want to go into octave.cc and look at the octave_main function.
Depending on what you are doing, you will need to include various pieces from
there, in this case install_ops().
Doug, are you adding this to your help document?
