| 6 | APT Config - Program to manipulate APT configuration files |
| 7 | |
| 8 | This program will parse a config file and then do something with it. |
| 9 | |
| 10 | Commands: |
| 11 | shell - Shell mode. After this a series of word pairs should occure. |
| 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` |
