description         The GNU Triangulated Surface library

long_description    GTS stands for the GNU Triangulated Surface Library. \
                    It is an Open Source Free Software Library intended \
                    to provide a set of useful functions to deal with \
                    3D surfaces meshed with interconnected triangles.
