//
// = DESCRIPTION
//    This file contains examples of IDL code that has 
//    caused problems in the past for the TAO IDL
//    compiler. This test is to make sure the problems
//    stay fixed.
//
// = AUTHORS
//    Jeff Parsons <parsons@cs.wustl.edu> and TAO users.
//
// ============================================================================

// These examples test the lookup abilities of the
// TAO IDL compiler, with reopened modules.

// Tests lookup function when modules are reopened by
// a chain of inclusions.
