+Custom parsing
+==============
+
+For many users, the data provided by the simple API is enough. In some advanced
+cases you may find it necessary to use this more customizable parsing mechanism.
+
+First, define a visitor that implements the :class:`CxxVisitor` protocol. Then
+you can create an instance of it and pass it to the :class:`CxxParser`.
+
+.. code-block:: python
+
+    visitor = MyVisitor()
+    parser = CxxParser(filename, content, visitor)
+    parser.parse()
+
+    # do something with the data collected by the visitor
+
+Your visitor should do something with the data as the various callbacks are
+called. See the :class:`SimpleCxxVisitor` for inspiration.
