; This script shows how to use IUnknown based COM Automation objects.
;
; Note: some unneeded interface functions which had special types have been replaced
; by dummies to avoid having to define those types. Do not remove these dummies as
; that would change the function indices which is bad. Also, not all function
; protoypes have been tested, only those used by this example.
