      The GNU Scientific Library (GSL) is a numerical library for C
      and C++ programmers.  It is free software under the GNU General
      Public License.

      The library provides a wide range of mathematical routines such
      as random number generators, special functions and least-squares
      fitting.  There are over 1000 functions in total with an
      extensive test suite.
