// = DESCRIPTION
//   This file contains TAO-specific idl interfaces (not part of CORBA
//   2.3).
//
//   This file was used to generate the code in TAO{C,S,S_T}.{h,i,cpp}
//   The code is then hand-crafted to compile it inside the ORB, avoid
//   cyclic dependencies and enforce the locality constraints on
//   certain objects.
