+        The Parma Polyhedra Library (PPL) provides numerical abstractions
+        especially targeted at applications in the field of analysis and
+        verification of complex systems.  These abstractions include convex
+        polyhedra, defined as the intersection of a finite number of (open or
+        closed) halfspaces, each described by a linear inequality (strict or
+        non-strict) with rational coefficients; some special classes of
+        polyhedra shapes that offer interesting complexity/precision tradeoffs;
+        and grids which represent regularly spaced points that satisfy a set of
+        linear congruence relations.  The library also supports finite
+        powersets and products of (any kind of) polyhedra and grids and a mixed
+        integer linear programming problem solver using an exact-arithmetic
+        version of the simplex algorithm.
