    longDescription = ''
      PARI/GP is a widely used computer algebra system designed for fast
      computations in number theory (factorizations, algebraic number theory,
      elliptic curves...), but also contains a large number of other useful
      functions to compute with mathematical entities such as matrices,
      polynomials, power series, algebraic numbers etc., and a lot of
      transcendental functions. PARI is also available as a C library to allow
      for faster computations.

      Originally developed by Henri Cohen and his co-workers (Université
      Bordeaux I, France), PARI is now under the GPL and maintained by Karim
      Belabas with the help of many volunteer contributors.

      - PARI is a C library, allowing fast computations.
      - gp is an easy-to-use interactive shell giving access to the PARI
        functions.
      - GP is the name of gp's scripting language.
      - gp2c, the GP-to-C compiler, combines the best of both worlds by
        compiling GP scripts to the C language and transparently loading the
        resulting functions into gp. (gp2c-compiled scripts will typically run
        3 or 4 times faster.) gp2c currently only understands a subset of the
        GP language.
