+libxdg-basedir
+--------------
+
+The libxdg-basedir project is a (really) small library used to provide
+the proper access to XDG directories as described by the XDG Base
+Directory Specification (0.6 version).
+
+The library can be found at
+https://n.ethz.ch/student/nevillm/download/libxdg-basedir/ , and it's
+imported in xine-lib as it's far from commonly found on distributions.
