+***************************
+Code Generation Terminology
+***************************
+
+Types of generated code
+=======================
+
+
+**Python Wrapper**
+  The code that exports the C++ wrapped class to Python. **Python wrapper**
+  refers to all the code needed to export a C++ class to Python, and
+  **Python method/function wrapper** means the specific function that calls
+  the C++ method/function on behalf of Python. This code is invoked from
+  the Python side.
+
+**C++ Wrapper**
+  This term refers to a generated C++ class that extends a class from the
+  wrapped library. It is generated only when a wrapped C++ class is
+  polymorphic, i.e. it has or inherits any virtual methods.
+  The **C++ Wrapper** overrides the virtual methods of the wrapped C++ class
+  with code that allows for overriding the method with a Python implementation.
+  It checks whether a corresponding method in the Python instance exists and
+  calls it. This code is invoked from the C++ side.
+
+
+Specifying a target for modifications
+=====================================
+
+In the typesystem files, the ``class`` attribute is used to which class a
+modification is applied (see :ref:`codeinjectionsemantics`,
+:ref:`objectownership`).
+The value **Target** means the modification is applied to the
+**Python Wrapper**. The value **Native** means the modification is applied to
+the **C++ Wrapper**.
