question concerning arranger tool

[Stefan Thomas]

Dear community,

I try to understand more of the arranger tool, have a look at

https://github.com/gilles-th/arranger.ly

Could someone give an instructional example, what the functions copy-out can do and how it works?

I generally think taht there should be more examples in the docs. I'm willing to help in this regard but therefore I sould understand a bit more of the staff.

Thanks,

Stefan
