+SUMMARY="Library for manipulating integer points bounded by affine constraints"
+DESCRIPTION="isl is a thread-safe C library for manipulating sets and \
+relations of integer points bounded by affine constraints.  The descriptions \
+of the sets and relations may involve both parameters and existentially \
+quantified variables.  All computations are performed in exact integer \
+arithmetic using GMP."
