description         Integer Set Library
long_description    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.
