   summary: "isl is a thread-safe C library for manipulating sets and relations of integer points bounded by affine constraints."
+  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.
