+ 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`
