540 "CLooG is a free software library to generate code for scanning
541Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
542reaches each integral point of one or more parameterized polyhedra.
543CLooG has been originally written to solve the code generation problem
544for optimizing compilers based on the polytope model. Nevertheless it
545is used now in various area e.g., to build control automata for
546high-level synthesis or to find the best polynomial approximation of a
547function. CLooG may help in any situation where scanning polyhedra
548matters. While the user has full control on generated code quality,
549CLooG is designed to avoid control overhead and to produce a very
550effective code.")
