+%description
+CLooG is a software which generates loops for scanning Z-polyhedra. That is,
+CLooG finds the code or pseudo-code where each integral point of one or more
+parametrized polyhedron or parametrized polyhedra union is reached. CLooG is
+designed to avoid control overhead and to produce a very efficient code.
