The MVFS allows derived objects that were built in one dynamic view to be automatically "copied" to another dynamic view that requires "exactly the same" derived object. Two derived objects are deemed to be "exactly same" if they have the same "configuration record" (that is, "bill of materials"). The shareable derived objects are physically present in the VOB server, not in the views that reference them. This feature is called "winking in" derived objects and requires that the clearmake or omake tool is used for builds.
