class Qhull(Package):
"""Qhull computes the convex hull, Delaunay triangulation, Voronoi
diagram, halfspace intersection about a point, furt hest-site
Delaunay triangulation, and furthest-site Voronoi diagram. The
source code runs in 2-d, 3-d, 4-d, and higher dimensions. 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.
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."""
