public class JarRunner
extends Object
JarRunner initializes sys (PySystemState), passing args in (including the
 name "__run__" as arg 0 for consistancy with Python expectations), and
 import __run__.  It is intended to be used to allow an application jarred up
 with Jython's runtime to run like "java -jar foo.jar".  It requires a
 __run__.py in the jar that will execute the program, and the following entry
 in the manifest:
 Main-Class: org.python.util.JarRunner
 XXX: For the moment it should be considered experimental, but it is simple
 enough that I expect to be able to remove this warning pretty quickly.
