+ (description
+ "This package makes the qhull library available in R, in a similar manner
+as in Octave. Qhull computes convex hulls, Delaunay triangulations, halfspace
+intersections about a point, Voronoi diagrams, furthest-site Delaunay
+triangulations, and furthest-site Voronoi diagrams. It runs in 2-d, 3-d, 4-d,
+and higher dimensions. It implements the Quickhull algorithm for computing
+the convex hull. Qhull does not support constrained Delaunay triangulations,
+or mesh generation of non-convex objects, but the package does include some R
+functions that allow for this. Currently the package only gives access to
+Delaunay triangulation and convex hull computation.")
+ ;; The Qhull sources are included and are distributed under a custom
+ ;; non-copyleft license. The R sources are released under GPL version 2.
