-% \subsection{Hook Modification Macros}
-% The following macros are used to modify the hooks, i.e.\ to prefix or append code to them.
-%
-%
-% \subsubsection*{Internal Macros}
-%
-% The macro prefixes for the file specific hooks are stored in macros to reduce the number of
-% tokens in the following macro definitions.
-% \begin{macrocode}
-\def\filehook at include@atbegin@{filehook at include@atbegin@}
-\def\filehook at include@atend@{filehook at include@atend@}
-\def\filehook at include@after@{filehook at include@after@}
-\def\filehook at input@atbegin@{filehook at input@atbegin@}
-\def\filehook at input@atend@{filehook at input@atend@}
-\def\filehook at input@after@{filehook at input@after@}
-\def\filehook at atbegin@{filehook at atbegin@}
-\def\filehook at atend@{filehook at atend@}
-\def\filehook at after@{filehook at after@}
-% \end{macrocode}
-%
-%
-% \begin{macro}{\filehook at append}
-% Uses default \LaTeX{} macro.
-% \begin{macrocode}
-\def\filehook at append{\g at addto@macro}
-% \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}{\filehook at appendwarg}
-% Appends code with one macro argument. The |\@tempa| intermediate step is required because of the
-% included |##1| which wouldn't correctly expand otherwise.
-% \begin{macrocode}
-\long\def\filehook at appendwarg#1#2{%
- \begingroup
- \toks@\expandafter{#1{##1}#2}%

-% The macro first expands the file name (|#3|) to flatten all included macros. An extension is added if missing, as well as the prefix.
-% All modifications of |\@tempa| are made inside a group to keep them local.
-% \begin{macrocode}

-% \begin{macro}{\@input@}
-% This macro is redefined for the \Macro\include file hooks.
-% Checks if the next command is \Macro\clearpage which indicates that we are inside \Macro\@include.
-% If so the hooks are installed, otherwise the original macro is used unchanged.
-% For the `after' hook an own \Macro\clearpage is inserted and the original one is gobbled.

-% The |filehook| default definition of \Macro\InputIfFileExists is defined here
