    <p>
      Giac is a Computer Algebra System made by Bernard Parisse. It  provides 
      features from the C/C++ libraries PARI, NTL (arithmetic), GSL (numerics), 
      GMP (big integers), MPFR (bigfloats) and also:</p>
    <ul>
      <li>Efficient algorithms for multivariate polynomial operations 
        (product, GCD, factorization, groebner bases)</li>
      <li>Symbolic computations: solver, simplifications, limits/series,
        integration</li>
      <li>Linear algebra with numerical or symbolic coefficients</li>
      <li>Partial Maple and TI compatibility</li>
      <li>It has interfaces in texmacs and sagemath</li>
    </ul>
    <p>It consists of:</p>
    <ul>
      <li>A C++ library (libgiac)</li>
      <li>A command line interpreter (icas/giac)</li>
      <li>An FLTK-based GUI (xcas) with interactive geometry and formal
        spreadsheets</li>
    </ul>
