- 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`
