One advantage of the format below is that it's very easily human-readable, and it's not too hard to parse (although I guess you'd have to parse the indent level to get parent/child relation, which would suck a bit). Is there room to provide both? Otherwise, I guess the kernel could include a script to convert from JSON/whatever into the format below.
