[Jython-dev] proposal: making jython.jar executable

[Zimmer, B. <Bri...@di...>]

Does anyone have objections to making jython.jar an executable jar?  It
requires a specialized manifest file which the enclosed patch to
build.xml creates.  This would mean one could start jython with:

 java -jar jython.jar

The existing batch files or shell scripts would continue to work just
fine.  I am proposing this because a couple people have asked recently.

thanks,

brian
