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...
