+ *
+ * The purpose of this example is to demonstrate the EPhysics Gravity usage -
+ * The code apply gravity in an EPhysics_World with two cubes in movement.
+ *
+ * For this example we'll have an EPhysics_World, and two basic EPhysics_Bodys.
+ *
+ * The basic concepts like - defining an EPhysics_World, render geometry,
+ * physics limiting boundaries, add an EPhysics_Body, associate it to evas
+ * objects, change restitution, friction and impulse properties, were
+ * already covered in
+ * @ref tutorial_ephysics_bouncing_ball
+ *
+ * Concepts like velocity and sleeping threshold were already
+ * covered in
+ * @ref tutorial_ephysics_velocity and 
+ * @ref tutorial_ephysics_sleeping_threshold
+ *
+ * @section add-gravity Setting Gravity
+ * @dontinclude test_no_gravity.c
+ *
+ * Here we set EPhysics_worlds gravity in 2 axises (x, y) to (0, 0). Gravity
+ * will act over bodies with mass over all the time.
+ *
+ * @skipline ephysics_world_gravity_set
+ *
+ * @section add-stopbody Stopping a Body
+ * @dontinclude test_no_gravity.c
+ *
+ * We're using a button to call this function that receives test_data to stop
+ * the chosen body.
+ *
+ * Stop angular and linear body movement, its equivalent to set linear velocity
+ * to 0 on both axis and angular velocity to 0 as well.
+ *
+ * @skip _stop(void *data
+ * @until body);
+ * @skipline }
+ *
+ * Here we finish the example. The full source code can be found at
+ * @ref test_no_gravity_c.
