APT Config - Program to manipulate APT configuration files
This program will parse a config file and then do something with it.
Commands:
shell - Shell mode. After this a series of word pairs should occure.
The first is the environment var to set and the second is
the key to set it from. Use like:
eval `apt-config shell QMode apt::QMode`
