The dustlet is now implemented as a user-exit, that minimizes the dependencies.
I also integrated and modified the JGrib code, in order not to have to worry about Log4J, which was not quite mandatory in our case.
The best way to get the new version is to uninstall, and then re-install. This is because of some implied structural changes in the soft.
After that, the auto-update feature will keep working OK.
