+ *
+ * The purpose of this example is to demonstrate the dynamically growing
+ * and shrinking of an EPhysics_Body - The code applies the growth of a ball
+ * and the shrink of another.
+ *
+ * For this example we'll have an EPhysics_World and three EPhysics_Bodys
+ * with different sizes associated with an evas_object.
+ *
+ * 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
+ *
+ * @section add-growshrink Adding the growing/shrinking
+ * @dontinclude test_growing_balls.c
+ *
+ * In this example we'll use a timer to handle the callback function.
+ *
+ * @skipline test_data->data = ecore_timer_add
+ *
+ * In this callback, we'll pass through a list with 3 balls and apply the
+ * growth and the shrink between the limit we'll set. Note that the variable
+ * i recieves different values on each iteration (-1, 0, 1). For the first
+ * iteration it will decrease the size variable, the second will keep the
+ * same value, and the last one will increase the size variable.
+ *
+ * @dontinclude test_growing_balls.c
+ *
+ * @skip _grow_cb(void *data
+ * @until return EINA_TRUE;
+ * @skipline }
+ *
+ * Here we finish the example. The full source code can be found at
+ * @ref test_growing_balls_c.
