description         Exchange-correlation functionals for DFT
long_description    Libxc is a library of exchange-correlation functionals \
                    for density-functional theory. The aim is to provide \
                    a portable, well tested and reliable set of exchange \
                    and correlation functionals that can be used by all \
                    the ETSF codes and also other codes.
