python-apt examples refactored

[Nicolas Chauvat <chauvat@nerim.net>]

Hello APT hackers,

While toying with python-apt today I had a look at the examples to 
figure out how things worked. As I usually do, I refactored the code to 
better understand it. The result is available at 
http://chauvat.nerim.net/python-apt/ Feel free to use it if you like it 
and find it improves readability.

I kind of lacked documentation about objects while discovering 
python-apt (what's the interface to elements of cache.Packages for 
example ?). Is it because I did not find it or because it does not exist 
? Would you welcome and include a further developed apt.py (see archive 
available from link above) ?
