       - Apache FOP <http://xmlgraphics.apache.org/fop/index.html> 
           (at least version 0.95, trunk is recommended)
           
-     - Hyphenation is done via FOP, so read a section on it in their docs.

+   CONFIGURING
+   -----------
+    
+     1) Compile FOP if needed.
+     2) Generate font metrics (refer to FOP Documentation on that)
+     3) Make a "fop-config.xml" out of the supplied example and place it in this directory.
