description         Parma Polyhedra Library
long_description    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, \
                    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 \
                    polyhedra and grids, a mixed integer linear \
                    programming problem solver using an exact-arithmetic \
                    version of the simplex algorithm, a parametric integer \
                    programming solver, and primitives for termination \
                    analysis via the automatic synthesis of linear ranking \
                    functions.
