Parma Polyhedra Library (Release 0.10.2)
========================================

This is the release 0.10.2 of the Parma Polyhedra Library:
a C++ library for (not necessarily closed) convex polyhedra
and other numerical abstractions.

To be more precise, the Parma Polyhedra Library (PPL) can handle:

+ all the convex polyhedra that can be defined as the intersection
    of a finite number of (open or closed) hyperspaces, each described
    by an equality or a (strict or non-strict) inequality with rational
    coefficients;

+ convex polyhedra defined by systems of bounded differences with
    a wide choice of integer, rational or floating point coefficients;

+ all grids (or, equivalently, lattices); a grid is defined by a set
    of congruence relations with rational coefficients and consists of
    the set of all points that satisfy these relations;

+ finite powersets of the above;

+ linear programming problems, solved with an implementation of the
    primal simplex algorithm using exact arithmetic.

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.
