description             NTL: A Library for doing Number Theory
long_description        NTL is a high-performance, portable C++ library providing\
                        data structures and algorithms for arbitrary length\
                        integers\; for vectors, matrices, and polynomials over the\
                        integers and over finite fields\; and for arbitrary\
                        precision floating point arithmetic.
