I've written the infrastructure to provide what you're asking, but I don't
think I ever hooked it up to a command-line app.  I'll do this shortly.
But in the end, it doesn't matter if you can't trust the data in the
header, as Michael suggests is often the case.  This really is too bad --
not much point in having the data if it's not correct.

We were talking about providing JSON output.  Would this work for you?
