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