This is apparently different and separate from Mozilla's manifest.webapp (which I guess is for Firefox OS?), but I don't know if it's a standardization of Chrome's manifest.json that I've seen elsewhere or something entirely new, but similar. Either way, the entire manifest ecosystem is really confusing right now.
