| == 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. |

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. |
