/// Transforms the deprecated `std::auto_ptr` into the C++11 `std::unique_ptr`.
20
///
21
/// Note that both the `std::auto_ptr` type and the transfer of ownership are
22
/// transformed. `std::auto_ptr` provides two ways to transfer the ownership,
23
/// the copy-constructor and the assignment operator. Unlike most classes these
24
/// operations do not 'copy' the resource but they 'steal' it.
25
/// `std::unique_ptr` uses move semantics instead, which makes the intent of
26
/// transferring the resource explicit. This difference between the two smart
27
/// pointers requeres to wrap the copy-ctor and assign-operator with
28
/// `std::move()`.
29
///
30
/// For example, given:
31
///
32
/// \code
33
/// std::auto_ptr<int> i, j;
34
/// i = j;
35
/// \endcode
36
///
37
/// This code is transformed to:
38
///
39
/// \code
40
/// std::unique_ptr<in> i, j;
41
