description         GiNaC is C++ library that provides a set of algebraic capabilities.
long_description    GiNaC is an iterated and recursive acronym for GiNaC is Not a CAS, \
                    where CAS stands for Computer Algebra System. Its design is \
                    revolutionary in a sense that contrary to other CAS it does not try \
                    to provide extensive algebraic capabilities and a simple programming \
                    language but instead accepts a given language (C++) and extends it \
                    by a set of algebraic capabilities.
