I can see in the [default template](https://github.com/mojohaus/webstart/blob/0f575797a67c8e8e9de02177395873c23804252e/webstart-maven-plugin/src/main/resources/default-jnlp-template.vm) that there is a `$arguments` placeholder. I've been looking around the source code, but can't figure out how to use it. It sure would be dandy to be able to pass stuff into the `<application-desc>` tag, can anyone help?
