%D \module
%D [ file=s-youless,
%D version=2013.11.12,
%D title=\CONTEXT\ Style File,
%D subtitle=Youless Graphics,
%D author=Hans Hagen,
%D date=\currentdate,
%D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}]
%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D This is experimental code. When I have collected enough data I will make the
%D graphics nicer and provide some more.
%D
%D The Jouless can serve web pages but there is not much detail in them. They also are
%D somewhat bad \HTML, like unquoted attributes and so. We don't need this anyway as we
%D can also fetch data directly. The data is collected using a dedicated helper script
%D (of course we could just call it as module too). The data is fetched from the Jouless
%D device using queries (currently we use json, but a more direct parsing of data might
%D be more efficient). The data is converted into a proper \LUA\ table and saved (merged).
