11%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
12%C details.

14%D This is experimental code. When I have collected enough data I will make the
15%D graphics nicer and provide some more.
16%D
17%D The Jouless can serve web pages but there is not much detail in them. They also are
18%D somewhat bad \HTML, like unquoted attributes and so. We don't need this anyway as we
19%D can also fetch data directly. The data is collected using a dedicated helper script
20%D (of course we could just call it as module too). The data is fetched from the Jouless
21%D device using queries (currently we use json, but a more direct parsing of data might
22%D be more efficient). The data is converted into a proper \LUA\ table and saved (merged).
