* @brief Helper class that initializes an ORB when an instance of
* this class is dynamically loaded.
*
* This class is deprecated. While it does demonstrate how to
* initialize an ORB in a dynamically loaded object, the fact that it
* is located in the TAO library forces the TAO library to be linked
* to the application binary. This prevents TAO from being completely
* decoupled from an application when dynamic loading is used, hence
* defeating the purpose of dynamically loading the object!
* @par
* For an example of how to dynamically load an ORB (actually initialize
* an ORB inside a dynamically loaded object) that is completely
* decoupled from an application binary see the TAO/tests/DLL_ORB
* test.
