description             spectral/hp element framework
long_description        Nektar++ is a spectral/hp element framework which aims to be easy \
                        to use and support a wide range of features, including 1D, 2D and \
                        3D element support, hybrid shaped elements and continuous and \
                        discontinuous implementations. As well as a modern C++ API, it \
                        ships with a range of solvers including CFD, advection-diffusion \
                        equations and cardiac electrophysiology.
