%description
Computation of the alpha-shape and alpha-convex hull of a given sample of
points in the plane. The concepts of alpha-shape and alpha-convex hull
generalize the definition of the convex hull of a finite set of points.
The programming is based on the duality between the Voronoi diagram and
Delaunay triangulation. The package also includes a function that returns
the Delaunay mesh of a given sample of points and its dual Voronoi diagram
in one single object.
