+Hermes library support
+----------------------
+
+If configure finds hermes library (an optimized pixel format conversion
+library) installed it will use it to do the pixel format conversion in
+the wraster library for some cases (TrueColor visuals without dithering).
+Currently the hermes routines cannot convert to an indexed destination,
+so we can't use hermes for PseudoColor, GrayScale and StaticGray visuals.
+Also hermes only does dithering for just 2 combinations of source/destination
+bits/masks none of them useful to out needs so for dithering we still
+use out routines.
+
+The Hermes library is completely optional, you can build Window Maker
+without having it, it just speeds up the things a little for some
+situations.
+
+hermes library is available here: http://www.clanlib.org/hermes/
