990Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
991reaches each integral point of one or more parameterized polyhedra.
992CLooG has been originally written to solve the code generation problem
993for optimizing compilers based on the polytope model. Nevertheless it
994is used now in various area e.g., to build control automata for
995high-level synthesis or to find the best polynomial approximation of a
996function. CLooG may help in any situation where scanning polyhedra
997matters. While the user has full control on generated code quality,
998CLooG is designed to avoid control overhead and to produce a very
999effective code.")
