%description
    PARI-GP is a software package for computer-aided number theory.
    It consists of the C library libpari and of the programmable
    interactive gp(1) calculator. While you can write your own
    libpari-based programs, many people just start up a gp(1) session,
    or have gp(1) execute their scripts.
