  //    concrete component class <class Concrete>.
  //
  // = DESCRIPTION
  //    This design is similar to the Adapter and Decorator patterns
  //    from the ``Gang of Four'' book.  Note that <class Concrete>
  //    need not inherit from a common class since ACE_Dumpable
  //    provides the uniform virtual interface!
