715 Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
716 reaches each integral point of one or more parameterized polyhedra.
717 CLooG has been originally written to solve the code generation problem
718 for optimizing compilers based on the polytope model. Nevertheless it
719 is used now in various area e.g., to build control automata for
720 high-level synthesis or to find the best polynomial approximation of a
721 function. CLooG may help in any situation where scanning polyhedra
722 matters. While the user has full control on generated code quality,
