+% \subsection{Custom description lists}
+%
+% For some bizarre reason, the \LaTeX\ \env{description} environment sets
+% |\itemindent| so that the label starts |\labelsep| into the left margin,
+% and the default |\makelabel| must therefore contain a hack to compensate.
+% This is fixed in the \package{strayman} document class, and by the
+% \package{mdwlist} package in this collection.  But this introduces a
+% problem: if I want to set a \env{description} list with custom labels, how
+% can I do this without messing up the spacing?
+%
+% Detection of the relevant packages is done in an awfully hacky way, because
+% \LaTeXe\ seems to go out of its way to forget which packages have been
+% loaded at |\begin{document}| time.
