description         GSL (GNU Scientific Library) bindings for OCaml
long_description    gsl-ocaml provides OCaml bindings for the GSL \
                    (GNU Scientific Library), giving access to algorithms \
                    for optimization, differential equations, statistics, \
                    random number generation, linear algebra, and more.
