986Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
987reaches each integral point of one or more parameterized polyhedra.
988CLooG has been originally written to solve the code generation problem
989for optimizing compilers based on the polytope model. Nevertheless it
990is used now in various area e.g., to build control automata for
991high-level synthesis or to find the best polynomial approximation of a
992function. CLooG may help in any situation where scanning polyhedra
993matters. While the user has full control on generated code quality,
994CLooG is designed to avoid control overhead and to produce a very
995effective code.")
