I was going to write a question about how to determine the path of a node under an @path node, since for this is not behaving as I'd expect...
... but whilst trying to create the simplest example, I was reminder that there must be something about the @path & @file (specifically @clean in this case) facility that I don't understand.
To encapsulate this parts of my question ... does the directory (as given by an @path node(s), and child @clean nodes, have to exist, before the file contents are written?
I always thought that the directory was created if it didn't exist ... but now I am not so sure.
Thanks, J^n
