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.
