### Commit format
Some assumptions are made about commit message formatting that will later be made more configurable. It is expected that commits conforms to the [Conventional Commit](https://www.conventionalcommits.org/en/v1.0.0/) scheme.
### Configuration
The groupings can be configured using a YAML file formatted as follows:
```yaml
groups:
- label: <Heading to identify the group with in the generated log>
prefixes: [<prefix1>, <prefix2, ...]
- label: ...
prefixes: ...
```
Each group is headed by its `label` value and contains a list of all the commits matching the prefix selection for that group.
If not supplied, a default configuration (see `modif.configuration.get_default_config`) is substituted in.
