Trouble in running rouge package

[pakdaman]

I was trying to use the rouge package in a multi reference scenario? Is it possible to provide an example in the rouge/readme on how one can do that?
In the current example in "How to run" where do you define the directory of the files?

Also, I am wondering how do you compute rouge for multi-reference scenario. Looking into the code you do some sort of bootstrap aggregation while in the original paper here (https://www.aclweb.org/anthology/W04-1013) in section 2 looks like they do simple micro-averaging while in section 2.1 it seems they do maximization over pairewise computation in rouge!

Thanks,
