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