    	description:
    		"Base class for Eiffel Vision implementation interface.
    		Eiffel Vision uses the bridge pattern. See notes in ev_any.e)
    		Descendents of this class are coupled to descendants of EV_ANY
    		(the base class for the Eiffel Vision interface) which provide user
    		access. When a class requires different implementation on different
    		platforms descendents of this class have further descendants with
    		an _IMP suffix.
    		eg. If button needs platform specific code then
    		    - EV_BUTTON is the user interface, (descendant of EV_ANY)
    		    - EV_BUTTON_I is the implementation interface,
    		      (descendant of EV_ANY_I)
    		    - EV_BUTTON_IMP is the native implementation.
    		      It is implemented once for each platform, the actual class
    		      included in a system at
    		      compile time is determined by the Ace file."
