% \DescribeEnv{graded}{The |graded| environment does nothing in latex,
% but in html, it wraps the activities in a div in order to assign
% some weight to them for grading.}

%<*classXourse>
\newenvironment{graded}[1]{}{}

% So indeed this environment in html wraps the activities in a div in
% order to assign some number of points to them.
