 **Note:** As of 18th May 2017 the [website](http://berouge.com/) for the official Perl package appears to be down. Unfortunately you need to download a directory called `ROUGE-1.5.5` from there. As an alternative, it seems that you can get that directory from [here](https://github.com/andersjo/pyrouge) (however, the version of `pyrouge` in that repo appears to be outdated, so best to install `pyrouge` from the [official source](https://pypi.python.org/pypi/pyrouge)).

+```
+[pyrouge settings]
+home_dir = <dir of rouge*.pl script>
