I can't see of a reason to have that, however I can see a reason to at least
have a package message to that affect. I'm not sure how to account for an
unknown amount of arguments in a shell script, unless there is only ever
going to be one argument? If the latter is the case, then including a shell
script would be nice.

How does this work?

#!/bin/sh

%%JAVA%% -jar %%JAVAJARDIR%%/%%PORTNAME%%.jar -classpath $1

Thanks!
