+
+// Summary: The Ort C++ API is a header only wrapper around the Ort C API.
+//
+// The C++ API simplifies usage by returning values directly instead of error codes, throwing exceptions on errors
+// and automatically releasing resources in the destructors. The primary purpose of C++ API is exception safety so
+// all the resources follow RAII and do not leak memory.
+//
+// Each of the C++ wrapper classes holds only a pointer to the C internal object. Treat them like smart pointers.
+// To create an empty object, pass 'nullptr' to the constructor (for example, Env e{nullptr};). However, you can't use them
+// until you assign an instance that actually holds an underlying object.
+//
+// For Ort objects only move assignment between objects is allowed, there are no copy constructors.
+// Some objects have explicit 'Clone' methods for this purpose.
+//
+// ConstXXXX types are copyable since they do not own the underlying C object, so you can pass them to functions as arguments
+// by value or by reference. ConstXXXX types are restricted to const only interfaces.
+//
+// UnownedXXXX are similar to ConstXXXX but also allow non-const interfaces.
+//
+// The lifetime of the corresponding owning object must eclipse the lifetimes of the ConstXXXX/UnownedXXXX types. They exists so you do not
+// have to fallback to C types and the API with the usual pitfalls. In general, do not use C API from your C++ code.
