+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, computing the lexicographic
+minimum using parametric integer programming, coalescing and parametric
+vertex enumeration. It also includes an ILP solver based on generalized
+basis reduction, transitive closures on maps (which may encode infinite
+graphs), dependence analysis and bounds on piecewise step-polynomials.
