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