Given a url of a jnlp file, JNLPDownloader downloads every jar declared in the main jnlp or extension, every native library, and stores them in a directory with scripts to run the application in Linux, Windows or Mac.
Usage:
java -jar jnlpdownloader.jar example http://www.example.com/application.jnlp
That will download the jnlp from http://www.example.com/application.jnlp and save it to the example directory.
As a simplified example, for a jnlp file:
```
Some Title
Some Vendor
Some Description
