+Qhull (Implements the Quickhull Algorithm)
+
+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. It implements the Quickhull
+algorithm for computing the convex hull. Qhull handles roundoff errors
+from floating point arithmetic. It computes volumes, surface areas,
+and approximations to the convex hull.
+
+Qhull does not support constrained Delaunay triangulations, triangulation of 
+non-convex surfaces, mesh generation of non-convex objects, or medium-sized
+inputs in 9-D and higher. 
+
+qhull is an optional dependency for the octave package.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
