description             NETGEN is an automatic 3d tetrahedral mesh generator
long_description        ${description}. It accepts input from constructive \
                        solid geometry (CSG) or boundary representation (BRep) \
                        from STL file format. The connection to a geometry kernel \
                        allows the handling of IGES and STEP files. NETGEN contains \
                        modules for mesh optimization and hierarchical mesh \
                        refinement.
