+\subsubsection*{Fixed Width \LaTeX{} Text}
+
+Having the \LaTeX{} text at a fixed width (hard-wrap) is useful when the source
+is under version control.  The fixed line lengths help with isolating the
+changes between diffs.
+
+Although the checklist mentions an 80 column width, any reasonable fixed width
+is fine.
+
+The hard-wrap shouldn't be done manually.  Most editors will have some facility
+for fixed width.  In emacs it is called auto-fill.  Some advice from previous
+and current students:
+
+\begin{itemize}
+\item In TEXMaker, you can do: User $>$ Run script $>$ hardwordwrap
+\item Wrapping is easy in VSCode, Emacs, and Vim
