description         A numerical library for C and C++ programmers
long_description    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.
