First and foremost, I’d like to show appreciation for DrWatson. It is an excellent package and an important contribution to the scientific community. I am impressed by how useful it can be.
That being said, I wished the produce\_or\_load function was better documented. I’m having trouble understanding what kind of input arguments should it have. Would anyone be willing to give me a simple usage example?

I think that I understood it already. My problem was that it wasn’t clear to me that config can carry data (this won’t affect the file name produced by savename).
