// = LIBRARY
// tests
//
// = DESCRIPTION
// This program tests both the ACE_Framework_Compondent and ACE_Repository.
// Since Framework Components are singletons that can live in dlls loaded
// via the Service Configurator framework, this test uses that framework
// to load services from a dll that has a singleton based on ACE_DLL_Singleton.
// When the dll is finally ready to be unloaded, the singleton will be
// automatically cleaned up just-in-time.
