[Python-Dev] Add a -z interpreter flag to execute a zip file

Certainly java won't let you specify -jar more than once, because that
would be telling it to *run* two files.  It *will*, however, let you
specify more than one jar in the classpath.  This is done all the
time, making the contents of those jars available for importing.

These aren't typically combined, since the whole point of running a
jar file is to have a single distributed package, but IIRC it is not
prohibited.
