+Java support
+
+Javac is one of the few compilers that behaves very badly:
+
+#. it outputs files where it wants to (-d is only for the package root)
+
+#. it recompiles files silently behind your back
+
+#. it outputs an undefined amount of files (inner classes)
+
+Remember that the compilation can be performed using Jython[1] rather than regular Python. Instead of
+running one of the following commands::
+
+   ./waf configure
+   python waf configure
+
+You would have to run::
+
+   java -jar /path/to/jython.jar waf configure
+
