description         macromolecular crystallography library
long_description    The goal of this project -- named gpp4 to \
                    distinguish it from CCP4 -- is to provide a \
                    drop-in replacement for the CCP4 libraries, that \
                    as carefully as possible implements the current \
                    CCP4 library interface, while not requiring the \
                    whole CCP4 package to be installed. \
                    Select a Fortran variant to build the Fortran interface library.
