% Here we collect up things that are more-or-less required to create a useful
% class but are not defined by the \LaTeX{} kernel for historical reasons. They
% are therefore largely copies from \texttt{article.cls} and contain
% \enquote{classical} definitions so that they follow the expectations of
% third-party code.
