+  \class TQComponentFactory qcomponentfactory.h
+  \brief The TQComponentFactory class provides static functions to create and register components.
+
+    \internal
+
+  The static convenience functions can be used both by applications to instantiate components,
+  and by component servers to register components.
+
+  The createInstance() function provides a pointer to an interface implemented in a specific
+  component if the component requested has been installed properly and implements the interface.
+
+  Use registerServer() to load a component server and register its components, and unregisterServer()
+  to unregister the components. The component exported by the component server has to implement the
+  TQComponentRegistrationInterface.
+
+  The static functions registerComponent() and unregisterComponent() register and unregister a single
+  component in the system component registry, and should be used when implementing the
+  \link TQComponentRegistrationInterface::registerComponents() registerCompontents() \endlink and
+  \link TQComponentRegistrationInterface::unregisterComponents() unregisterCompontents() \endlink functions
+  in the TQComponentRegistrationInterface.
+
+  A component is registered using a UUID, but can additionally be registered with a name, version and
+  description. A component registered with a name and a version can be instantiated by client applications
+  using the name and specific version number, or the highest available version number for that component by
+  just using the name. A component that is registered calling
+
+  \code
+  TQComponentFactory::registerComponent( TQUuid(...), filename, "MyProgram.Component", 1 );
+  \endcode
+
+  can be instantiated calling either:
+
+  \code
+  TQComponentFactory::createInstance( TQUuid(...), IID_XYZ, (TQUnknownInterface**)&iface );
+  \endcode
+  or
+  \code
+  TQComponentFactory::createInstance( "MyProgram.Component", IID_XYZ, (TQUnknownInterface**)&iface );
+  \endcode
+  or
+  \code
+  TQComponentFactory::createInstance( "MyProgram.Component.1", IID_XYZ, (TQUnknownInterface**)&iface );
+  \endcode
+
+  The first and the last way will always instantiate exactly the component registered above, while
+  the second call might also return a later version of the same component. This allows smoother upgrading
+  of components, and is easier to use in application source code, but should only be used when new versions
+  of the component are guaranteed to work with the application.
+
+  The component name can be anything, but should be unique on the system the component is being
+  installed on. A common naming convention for components is \e application.component.
