- Adjust one or more directed graphs to improve the layout aspect ratio:

`unflatten {{path/to/input1.gv}} {{path/to/input2.gv ...}} > {{path/to/output.gv}}`

- Use `unflatten` as a preprocessor for `dot` layout to improve aspect ratio:

`unflatten {{path/to/input.gv}} | dot -T {{png}} {{path/to/output.png}}`

- Display help:

`unflatten -?`
