+ (description
+ "@code{Qhull} computes the convex hull, Delaunay triangulation, Voronoi
+diagram, halfspace intersection about a point, furthest-site Delaunay
+triangulation, and furthest-site Voronoi diagram. The source code runs in 2-d,
+3-d, 4-d, and higher dimensions. @code{Qhull} implements the Quickhull
+algorithm for computing the convex hull. It handles roundoff errors from
+floating point arithmetic. It computes volumes, surface areas, and
+approximations to the convex hull.
+
+@code{Qhull} does not support triangulation of non-convex surfaces, mesh
+generation of non-convex objects, medium-sized inputs in 9-D and higher, alpha
+shapes, weighted Voronoi diagrams, Voronoi volumes, or constrained Delaunay
+triangulations.")
