"""Configuration file and command line argument parser.
|
|
|
|
Gives a dictionary named `config` with configuration parsed either from
|
|
`/etc/kibicara.conf` or from a file given by command line argument `-f`.
|
|
If no configuration was found at all, the defaults are used.
|
|
|
|
Example:
|
|
```
|
|
from kibicara.config import config
|
|
print(config)
|
|
```
