 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 documentation.
