jython 2.5.3-17ubuntu1 (amd64 binary) in ubuntu artful

 Jython is an implementation of the high-level, dynamic, object-oriented
 language Python seamlessly integrated with the Java platform. The
 predecessor to Jython, JPython, is certified as 100% Pure Java.
 .
 Jython is complementary to Java and allows the two languages to be freely
 mixed. It is especially suited for embedded scripting, interactive
 experimentation and rapid application development, and it can
 interact with Java packages or with running Java applications.
