Or just svn update :-)

Yeah. I'm not proud of it, I just needed "some kind of GUI or something
just so you can see it doing, you know, *something*". If you write
something better I'll gladly take a gander.

Yeah, that was an explicit goal. Do be warned that, as the manpage
discusses raw output:

       These options are not intended to be used by end users using the command line, they
       are support options for the GUI component. Use or rely on them at your own peril.

              Write  all readings to stdout. The format is unlikely to change in practice,
              but if you choose to try to parse this yourself, I don't want to hear  about
              it when it does change.

As you can imagine, of course, this is vanishingly unlikely to
*actually* ever change, but I didn't want to fully commit to other
people being able to this in case I ever alter it to be some kind of
richer format. In all likelihood, if I added a new format, it'd be a
separate option.
