description     Another GNU Fortran 95 compiler
long_description \
                G95 is a stable, production Fortran 95 compiler \
                available for multiple cpu architectures and operating systems. \
                Innovations and optimizations continue to be worked on. \
                Parts of the F2003 standard have been implemented in g95.
