   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`
