-<p>The LayerManager ...</p>
+<p>SDLx::LayerManager is a package to handle a bunch of layers. A layer (see SDLx::Layer) is an SDL::Surface, the position of the surface on screen and some additional information.</p>
+<p>The layermanager gives you the opportunity to obtain the layer at a given point on screen and get the layers that are ahead or behind a layer.</p>
+<p>You will even be able to attach one or more layers to the mouse, e.g. for simulation some drag&amp;drop functionality.</p>
