+XDG provides an easy to use Ruby library for working with XDG standards.
+
+Presently, it only supports the XDG Base Directory Standard.
+
+If your program utilizes user or system-wide support files (e.g. configuration
+files), you owe it to yourself to checkout the XDG base directory standard.
+
+You can learn more about the standard at:
+http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
