Looked promising. Very concise. Thank you very much. However, I had no 
look installing appscript. I installed the two packages as you suggested 
(OS X 10.3 with Apple supplied Python). Below is what happened. Maybe some 
more updates necessary? (I assume installing appscript-0.13.1.tar.gz was 
meant as a patch to the pure binary installation.)


from appscript import app
from macfile import Alias
import os

path = '/Users/oberlaender/dead.letter'
assert os.path.exists(path)
print app('Finder').items[Alias(path)].label_index.get()

pythonw -i test.py
