"""
Build a zip for your app to test it.

Make sure to install ET so we can read attributes of our app from the descriptor
file.  This makes sure that you only have to edit things in one place and the
behaviour of packagaing your app will always be what you want it to ( that is of 
course you dont't update your descriptor file :))
