//  Boost scoped_ptr_example header file  ------------------------------------//

#include <boost/utility.hpp>
#include <boost/scoped_ptr.hpp>

//  The point of this example is to prove that even though
//  example::implementation is an incomplete type in translation units using
//  this header, scoped_ptr< implementation > is still valid because the type
//  is complete where it counts - in the inplementation translation unit where
//  destruction is actually instantiated.
