+      CLooG is a free software library to generate code for scanning
+      Z-polyhedra.  That is, it finds a code (e.g., in C, FORTRAN...) that
+      reaches each integral point of one or more parameterized polyhedra.
+      CLooG has been originally written to solve the code generation problem
+      for optimizing compilers based on the polytope model.  Nevertheless it
+      is used now in various area e.g., to build control automata for
+      high-level synthesis or to find the best polynomial approximation of a
+      function.  CLooG may help in any situation where scanning polyhedra
+      matters.  While the user has full control on generated code quality,
+      CLooG is designed to avoid control overhead and to produce a very
+      effective code.
