description         a Matlab-like environment for numerical analysis
long_description    Octave provides a convenient command line interface \
                    for solving linear and nonlinear problems numerically, \
                    using a language that is mostly compatible with Matlab. \
                    It is easily extensible and customizable via \
                    user-defined functions or using dynamically loaded \
                    modules written in e.g. C++, C or Fortran.
