-== Standalone mode - Libraries included ==
Jython has now a standalone mode, where the core part is all included in one single `jython.jar` file. This has two advantages:
 * simpler starting: `java -jar jython.jar`
 * simpler embedding: just put `jython.jar` onto your classpath. No setting of `python.home` nor `python.path` required.
This really adds a Plug & Play feature to Jython.

One Open issue: the cachedir problem still remains. If the directory containing `jython.jar` is not writable, no cachedir will help importing java classes. This is a well known problem also persistent in non-standalone mode. We try to improve this in standalone mode.
