+/* SFML::Input provides a way to access the state of keys, mouse buttons, 
+ * mouse position, joystick buttons and jostick axis.
+ *
+ * SFML::Input provides the same informations as the event system, but these 
+ * informations can be accessed at any time, which is more convenient in many 
+ * situations.
+ *
+ * For example, to move an entity you can decide to catch the 
+ * SFML::Event::KeyPressed event on arrow keys. But if you do so, you will only 
+ * receive one event when the key gets pressed (or repeated events if you 
+ * activated this feature), thus the entity will not move smoothly. The best 
+ * solution here is to use sf::Input::IsKeyDown so that you can update your 
+ * entity's position at every iteration of your game loop, not only when you 
+ * catch a KeyPressed event.
+ *
+ * Note that instances of sf::Input cannot be created directly, they must be 
+ * retrieved from a window (sf::Window) with its GetInput() function.
+ *
+ * Usage example:
+ * 
+ *   # Retrieve the input object attached to our window
+ *   input = window.getInput();
+ *   
+ *   # Move an entity according to the current keys state
+ *   offset = 5.0 * window.GetFrameTime(); # 5 pixels/sec
+ *   entity.move( -offset, 0 ) if input.isKeyDown(SFML::Key::Left) == true
+ *   entity.move( offset, 0 )  if input.isKeyDown(SFML::Key::Right) == true 
+ *   entity.move( 0, -offset ) if input.isKeyDown(SFML::Key::Up) == true
+ *   entity.move( 0,  offset ) if input.isKeyDown(SFML::Key::Down) == true
