+		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.
+
+		In Libxc you can find different types of functionals: LDA, GGA, hybrids, and mGGA (experimental).
+		These functionals depend on local information, in the sense that the value of the potential
+		at a given point depends only on the values of the density -- and the gradient of the density
+		and the kinetic energy density, for the GGA and mGGA cases.
+
+		It can calculate the functional itself and its derivative; for some functionals,
+		higher-order derivatives are available.
+
+		Libxc is written in C and has Fortran bindings. It is released under the MPL2 license.
+		Contributions are welcome.
