+/* -----------------------------------------------------------------------------
+ * std_unique_ptr.i
+ *
+ * SWIG library file for handling std::unique_ptr.
+ *
+ * Returning a std::unique_ptr from a wrapped function:
+ *   Memory ownership is passed (moved) from the std::unique_ptr in the C++ layer
+ *   to the proxy class when returning a std::unique_ptr by value from a function.
+ *   Memory ownership is not moved when returning by any sort of reference.
+ *
+ * Passing a std::unique_ptr as a parameter to a wrapped function:
+ *   Memory ownership is passed from the proxy class to the std::unique_ptr in the
+ *   C++ layer when passed as a parameter by value, rvalue reference or non-const
+ *   lvalue reference. Memory ownership is not transferred when passing by const
+ *   lvalue reference.
