The Parma Polyhedra Library (PPL) is a C++ library for the
manipulation of (not necessarily closed) convex polyhedra and other
numerical abstractions. The applications of convex polyhedra include
program analysis, optimized compilation, integer and combinatorial
optimization and statistical data-editing. The Parma Polyhedra
Library is user friendly (you write `x + 2*y + 5*z <= 7' when you
mean it), fully dynamic (available virtual memory is the only
limitation to the dimension of anything), written in standard C++,
exception-safe, rather efficient and thoroughly documented.
This package provides the SWI Prolog interface.
