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