+================================
+
+isl is a library for manipulating sets and relations of integer points bounded by linear constraints.
+Supported operations on sets include intersection, union, set difference, emptiness check, convex hull,
+(integer) affine hull, integer projection, and computing the lexicographic minimum using parametric
+integer programming. It also includes an ILP solver based on generalized basis reduction and operations
+geared towards polyhedral compilation such as dependence analysis, scheduling, and AST generation.

+===============================
+
+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, defined as the intersection of a finite number
+of (open or closed) halfspaces, each described by a linear inequality (strict or
+non-strict) with rational coefficients; 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 (any kind 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.
+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); portable (written in standard C++, with C, Java, Objective CAML and Prolog
+interfaces, and following all the applicable standards); exception-safe (never leaks
+resources or leaves invalid object fragments around); efficient (and we hope to make
+it even more so); thoroughly documented; free software (distributed under the terms of
+the GNU General Public License version 3 or any later version).
