description         A chemistry file translation program.
long_description    Open Babel is a free, open-source version \
                    of the Babel chemistry file translation program. \
                    OpenBabel is a project designed to pick up where \
                    Babel left off, as a cross-platform program and \
                    library designed to interconvert between many \
                    file formats used in molecular modeling and \
                    computational chemistry.
