The Parma Polyhedra Library (PPL) is a modern C++ library for the manipulation of convex polyhedra. To be more precise, the PPL can handle all the convex polyhedra that can be defined as the intersection of a finite number of closed hyperspaces, each described by an equality or a non-strict inequality with rational coefficients. (More details are available on the PPL's internal mechanisms.) 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++: meant to be portable;
• exception-safe: never leaks resources or leaves invalid object fragments around;
• rather efficient: and we hope to make it even more so;
• thoroughly documented: perhaps not literate programming but close enough;
• free software: distributed under the terms of the GNU General Public License.
