I haven’t really done anything with the platform yet, but I was looking around and saw “internetionalization” (which I naturally thought said “internationalization” at first) under the tools menu. I can probably give a real close guess as to what this is and what it does, but I wanted to know for sure rather than bask in my ignorance. Can someone help me out?

Its replacing all (selected) strings in your app with strings from resource bundles (text files) for easy internationalization.
