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.
