""" 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)
```
