+/// Transforms the deprecated `std::auto_ptr` into the C++11 `std::unique_ptr`.
+///
+/// Note that both the `std::auto_ptr` type and the transfer of ownership are
+/// transformed. `std::auto_ptr` provides two ways to transfer the ownership,
+/// the copy-constructor and the assignment operator. Unlike most classes these
+/// operations do not 'copy' the resource but they 'steal' it.
+/// `std::unique_ptr` uses move semantics instead, which makes the intent of
+/// transferring the resource explicit. This difference between the two smart
+/// pointers requeres to wrap the copy-ctor and assign-operator with
+/// `std::move()`.
+///
+/// For example, given:
+///
+/// \code
+///   std::auto_ptr<int> i, j;
+///   i = j;
+/// \endcode
+///
+/// This code is transformed to:
+///
+/// \code
+///   std::unique_ptr<in> i, j;
+///   i = std::move(j);
+/// \endcode
