 ==========
 KivEnt is a framework for building performant, dynamic real-time scenes in [Kivy](http://kivy.org/#home) for Python2 and Python3. At the moment it is 2d oriented. The only dependency for the kivent_core module is Kivy itself. Additional modules may have other requirements, such as kivent_cymunk module being based on [Chipmunk2d](https://chipmunk-physics.net/) and its [cymunk wrapper](https://github.com/tito/cymunk).

+# Creating a GameSystem
+
+This example shows how to create a KivEnt gamesystem.
+
+To run the main_with_cython.py example, first cythonize the velocity module:
+
+```
+$ cythonize -a -i ./velocity_module/velocity.pyx
+```
+
+This will create shared object files alongside the cython source, which python
+can import directly. Then run the example as usual:
+
+```
+$ python ./main_with_cython.py
+```

+        class.
+        :Parameters:
+            `root`: :class:`Widget`
+                The root widget that instantiated this widget in kv, if the
+                widget was instantiated in kv, otherwise ``None``.
+            `ignored_consts`: set
+                (internal) See :meth:`~kivy.lang.builder.BuilderBase.apply`.
+            `rule_children`: list
+                (internal) See :meth:`~kivy.lang.builder.BuilderBase.apply`.
+        This is useful to be able to execute code before/after the class kv
+        rules are applied to the widget. E.g. if the kv code requires some
+        properties to be initialized before it is used in a binding rule.
+        If overwriting remember to call ``super``, otherwise the kv rules will
+        not be applied.
+        In the following example,
+        .. code-block:: python
+            class MyWidget(Widget):
+                pass
+            class OtherWidget(MyWidget):
+                pass
+        .. code-block:: kv
+        <MyWidget>:
+            my_prop: some_value
+        <OtherWidget>:
+            other_prop: some_value
+        When ``OtherWidget`` is instantiated with ``OtherWidget()``, the
+        widget's :meth:`apply_class_lang_rules` is called and it applies the
+        kv rules of this class - ``<MyWidget>`` and ``<OtherWidget>``.
+        Similarly, when the widget is instantiated from kv, e.g.
+        .. code-block:: kv
+            <MyBox@BoxLayout>:
+                height: 55
+                OtherWidget:
+                    width: 124
+        ``OtherWidget``'s :meth:`apply_class_lang_rules` is called and it
+        applies the kv rules of this class - ``<MyWidget>`` and
+        ``<OtherWidget>``.
+        .. note::
+            It applies only the class rules not the instance rules. I.e. in the
+            above kv example in the ``MyBox`` rule when ``OtherWidget`` is
+            instantiated, its :meth:`apply_class_lang_rules` applies the
+            ``<MyWidget>`` and ``<OtherWidget>`` rules to it - it does not
+            apply the ``width: 124`` rule. The ``width: 124`` rule is part of
+            the ``MyBox`` rule and is applied by the ``MyBox``'s instance's
+            :meth:`apply_class_lang_rules`.
