+    (description "@code{Tweeny} is an inbetweening library designed for the
+creation of complex animations for games and other beautiful interactive
+software.  It leverages features of modern @code{C++} to empower developers with
+an intuitive API for declaring tweenings of any type of value, as long as they
+support arithmetic operations.  The goal of @code{Tweeny} is to provide means to
+create fluid interpolations when animating position, scale, rotation, frames or
+other values of screen objects, by setting their values as the tween starting
+point and then, after each tween step, plugging back the result.")
