   pgf-experimental/  – experimental Rascal implementation, with some examples. The interesting stuff is in src/org/nuthatchery/pgf/rascal/engines (a spacer and two line breaking variants). The examples found in our submitted SLE2013 paper can be found by importing org::nuthatchery::pgf::rascal::tests::TestPaper and running testPaper1() and testPaper2()
 
+  pgf-java-formatter/ – experimental Java formatter build using PGF. The main program is in /pgf-java-formatter/src/org/nuthatchery/pgf/javaformatter/JavaFormatter.java
+
 
 There is also a somewhat different experimental implementation in Racket. It can be found from a separate repository [on GitHub](https://github.com/bldl/pgf-racket "PGF in Racket").
+
+
+Dependencies:
+
+In order to use the Java formatter, you need  Nuthatch, Nuthatch/Stratego, Nuthatch/JavaFront and Stratego/XT.
