 font specification <http://www.w3.org/TR/1998/REC-CSS2-19980512/>`_.
 Future versions may implement the Level 2 or 2.1 specifications.
 
-Experimental support is included for using `fontconfig` on Unix
-variant platforms (Linux, OS X, Solaris).  To enable it, set the
-constant ``USE_FONTCONFIG`` in this file to ``True``.  Fontconfig has
-the advantage that it is the standard way to look up fonts on X11
-platforms, so if a font is installed, it is much more likely to be
-found.
