# You can use lookup mode to retrieve your app’s current metadata. 
# Lookup mode will create an App Store package at the set destination. 
# The package name will be the app's SKU with the .itmsp extension. 
# For example, if your app’s SKU is “myapp1” on iTunes Connect, 
# your filename would be myapp1.itmsp. The metadata.xml file within 
# the App Store package contains the app's metadata.
