Updating an AIR application

I know there is a built-in update framework inside AIR but finding valid code samples for the latest versions proves to be hard. Some code for simple up开发者_C百科dating (assuming ActionScript 3, AIR 2.7 and Flex 4.5) would be deeply appreciated (nothing fancy, default styles etc).

This is the code I used to get this working: http://www.adobe.com/devnet/air/articles/air_update_framework.html. It's a good overview (even down to doing a custom update window), and is trivial to implement.
