 * class and is instantiated with the implementation of the
 * concrete component class <class Concrete>.
 *
 * 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!
