+Libxc (a library of exchange-correlation functionals for 
+ density-functional theory)
+
+Libxc is a library of exchange-correlation and kinetic energy
+ functionals for density-functional theory. The original aim 
+was to provide a portable, well tested and reliable set of 
+these functionals to be used by all the codes of the European 
+Theoretical Spectroscopy Facility (ETSF), but the library has
+ since grown to be used in several other types of codes as well.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
