Delete unused resources in universal apps?

That's a really good idea. I'm surprised nobody has done this yet. Perhaps there would be side effects? Maybe I should try manually deleting all the iPad images from an app to see what happens.

 

I'm sure there is a way through Terminal commands but I'm not familiar enough with them. I currently use this command to delete all other localizations aside from English.

Code:

find / -type d \
-name "*.lproj" -not -iname "en*.lproj" \
-not -iname "template*.lproj" \
-exec /bin/rm -vrf '{}' \;

I have a vague understanding of how those commands are working but not sure how to modify them to work for other files. Maybe someone else with experience can assist?
