long_description    \
                    The goal of the CGAL is to provide easy access to\
                    efficient and reliable geometric algorithms in the\
                    form of a C++ library. CGAL is used in various areas\
                    needing geometric computation, such as: computer\
                    graphics, scientific visualization, computer aided\
                    design and modeling, geographic information systems,\
                    molecular biology, medical imaging, robotics and\
                    motion planning, mesh generation, numerical methods...
