+   
+   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 occur.
+             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`
