+% \DescribeMacro{\cftZprehook}

+% It's surprisingly difficult to achieve multicolumn ToCs; can you guess what the problem is to write the following?
+% \begin{verbatim}
+% \begin{multicols}{2}
+% \tableofcontents
+% \end{multicols}
+% \end{verbatim}
+% Probably the easiest way to do it in regular \LaTeX{} is something like
+% \begin{verbatim}
+% \RequirePackage{multicol}
+% \AtBeginDocument{\addtocontents{toc}{\protect\begin{multicols}{2}}}
+% \AtEndDocument  {\addtocontents{toc}{\protect\end  {multicols}}}
+% \end{verbatim}
+% This method of writing to the |.toc| file is most flexible for trying to control the typesetting output within the table of contents.
+%
+% To make this \emph{slightly} easier with \Lpack{tocloft}, the following macros are available: \cs{cftZprehook} and \cs{cftZprehook}, where |Z| is |toc|, |lof|, |lot|, etc.
+% If these are defined, they insert material just before the actual typesetting of the entries of the table of contents and so on.
+% A multicolumn ToC can therefore be achieved with this:
+% \begin{verbatim}
+% \RequirePackage{multicol}
+% \renewcommand\cfttocprehook{\begin{multicols}{2}}
+% \renewcommand\cfttocposthook{\end{multicols}}
