+The algorithm is written with Lua, and depending upon the choice of the
+engine, the drawing is done by MetaPost (with @code{luamplib}) or by TikZ.
+The Delaunay triangulation algorithm is the Bowyer and Watson algorithm.
+Several macros are provided to draw the global mesh, the set of points, or
+a particular step of the algorithm.")
