//                 C++ exception for throwing python exceptions
//                 ============================================
// Purpose: A C++ exception class for throwing python exceptions
//          through C++ code.
// Created: Apr, 2004, sss, from the version in D0's python_util.
//
// Note: Don't be tempted to declare the virtual functions defined here
//       as inline.
//       If you do, you may not be able to properly throw these
//       exceptions across shared libraries.

      ~TManageMagic() { delete (int*)PyROOT::TPyExceptionMagic; }
   } manageMagic;
