+% \begin{abstract}
+% This package provides hooks for input files. Document and package authors can use these hooks to
+% execute code at begin or the end of specific or all input files.
+% \end{abstract}
+%
+%
+% \section{Introduction}
+% These package changes some internal \LaTeX{} macros used to load input files so that they include `hooks'.
+% A hook is an (internal) macro executed at specific points. Normally it is initially empty, but can be extended using
+% an user level macro. The most common hook in \LaTeX{} is the `At-Begin-Document' hook. Code can be added to this hook
+% using \Macro\AtBeginDocument{<\TeX\ code>}.
+%
+%
+% This package provides hooks for files read by the \LaTeX{} macros \Macro\input, \Macro\include and
+% \Macro\InputIfFileExists as well as (since v0.3 from 2010/12/20) for class and package files,
+% i.e. macros \Macro\documentclass, \Macro\LoadClassWithOptions and \Macro\LoadClass
+% as well as \Macro\usepackage, \Macro\RequirePackageWithOptions and \Macro\RequirePackage.
+% Note that \Macro\InputIfFileExists, and therefore its hooks, is used by the aforementioned macros.
+% In v0.4 from 2011/03/01 special hooks where added which are executed for every read file, but will not be
+% executed a second time by the internal \Macro\InputIfFileExists inside \Macro\input and \Macro\include.
+%
+% For all files a `AtBegin' and a `AtEnd' hook is installed. For \Macro\include files there is also a `After' hook which
+% it is executed \emph{after} the page break (\Macro\clearpage) is inserted by the \Macro\include code.
+% In contrast, the `AtEnd' hook is executed before the trailing page break
+% and the `AtBegin' hook is executed after the \emph{leading} page break.
+% The `AtBegin' hook can be used to set macros to file specific values.
+% These macros can be reset in the `AtEnd' hook to the parent file values.
+% If these macros appear in the page header or footer they need to be reset `After' hook
+% to ensure that the correct values are used for the last page.
+%
+% In addition to general hooks which are executed for all files of there type,
+% file specific one can be defined which are only executed for the named file.
+% The hooks for classes and packages are always specific to one file.
+%
+% Older versions of this package provided the file name as argument |#1| for the general hooks.
+% This has been changed in v0.4 from 2011/01/03: the hook code is stored and executed without modifications,
+% i.e.\ macro argument characters (|#|) are now handled like normal and don't have to be doubled.
+% See section~\ref{sec:upgrade} for information how to upgrade older documents.
+%
+% \section{Usage}
+% The below macros can be used to add material (\TeX{} code) to the related hooks.
+% All `AtBegin' macros will \emph{append} the code to the hooks, but the `AtEnd' and `After' macros will \emph{prefix} the code instead.
+% This ensures that two different packages adding material in `AtBegin'/`AtEnd' pairs do not overlap each other.
+% Instead the later used package adds the code closer to the file content, `inside' the material added by the first package.
+% Therefore it is safely possible to surround the content of a file with multiple \LaTeX{} environments using multiple `AtBegin'/`AtEnd' macro calls.
+% If required inside another package a different order can be enforced by using the internal hook macros shown in the implementation section.
+%
+%^^A Some internal macros to draw the hook positions:
+% \def\Hook#1{\textsf{Hook: #1}\MacroArgs}
+%
+% \def\DrawInputIfB#1{%
+% \hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\InputIfFileExists:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\Hook{AtBeginOfFile}{<file name>}}%
+% #1%
+% \hbox{\Hook{AtBeginOfFiles}}%
+% \hbox{\fbox{\emph{Content}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfFiles}}%
+% \hbox{\Hook{AtEndOfFile}{<file name>}}%
+% }}}%
+% }}%
+% }%
+%
+% \def\DrawInputIf#1{%
+% \hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\InputIfFileExists:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\Hook{AtBeginOfEveryFile}}%
+% \hbox{\Hook{AtBeginOfFile}{<file name>}}%
+% #1%
+% \hbox{\Hook{AtBeginOfFiles}}%
+% \hbox{\fbox{\emph{Content}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfFiles}}%
+% \hbox{\Hook{AtEndOfFile}{<file name>}}%
+% \hbox{\Hook{AtEndOfEveryFile}}%
+% }}}%
+% }}%
+% }%
+%
+%
+% \subsection*{Every File}
+%
+% \DescribeMacro{\AtBeginOfEveryFile}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfEveryFile}{<\TeX\ code>}
+% Sometime certain code should be executed at the begin and end of every read file, e.g.\ pushing and popping a file stack.
+% The `At...OfFiles' hooks already do a good job here. Unfortunately there is the issue with the \Macro\clearpage in \Macro\include.
+% The \Macro\AtEndOfFiles is executed before it, which can cause issues with page headers and footers.
+% A workaround, e.g.\ done by older versions of the \pkg{currfile} package, is to execute the code twice for include files:
+% once in the |include| related hooks and once in the |OfFiles| hooks.
+%
+% A better solution for this problem was added in v0.4 from 2011/01/03:
+% the |EveryFile| hooks will be executed exactly once for every file, independent if it is
+% read using \Macro\input, \Macro\include or \Macro\InputIfFileExists.
+% Special care is taken to suppress them for the \Macro\InputIfFileExists inside \Macro\input and \Macro\include.
+%
+% These hooks are located around the more specific hooks:
+% For \Macro\input files the `Begin' hook is executed before the \Macro\AtBeginOfInputs hook and the `End' hook after
+% the \Macro\AtEndOfInputs.
+% Similarly, for \Macro\include files the `Begin' hook is executed before the \Macro\AtBeginOfIncludes hook and the `End' hook after
+% the \Macro\AfterIncludes\relax (!).
+% For files read by \Macro\InputIfFileExists\relax (e.g. also for \Macro\usepackage, etc.) they are executed before and after the
+% \Macro\AtBeginOfFiles and \Macro\AtEndOfFiles hooks, respectively.
+% Note that the \Macro\AtBeginOfEveryFile hook is executed before the \Macro\AtBeginOfPackageFile/\Macro\AtBeginOfClassFile hooks
+% and that the \Macro\AtEndOfEveryFile hook is executed also before the hooks \Macro\AtEndOfPackageFile/\Macro\AtEndOfClassFile.
+% Therefore the `Every' and `PackageFile'/`ClassFile' hooks do not nest correctly like all other hooks do.
+%
+%
+% \subsection*{All Files}
+%
+% \DescribeMacro{\AtBeginOfFiles}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfFiles}{<\TeX\ code>}
+% These macros add the given \marg{code} to two hooks executed for all files read using the \Macro\InputIfFileExists macro. This macro is used internally by the
+% \Macro\input, \Macro\include and \Macro\usepackage/\Macro\RequirePackage macros. Packages and classes might use it to include additional or auxiliary files.
+% Authors can exclude those files from the hooks by using the following code instead:\\\hspace*{\bigskipamount}\Macro\IfFileExists{<file name>}'{\@input\@filef@und}{}'
+%
+% \DescribeMacro{\AtBeginOfFile}{<file name>}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfFile}{<file name>}{<\TeX\ code>}
+% Like the {\Macro{...OfIncludeFile}{<file name>}{<\TeX\ code>}} macros above, just for `all' read files.
+% If the \meta{file name} does not include a file extension it will be set to `|.tex|'.
+%
+% The `all files' hooks are closer to the file content than the \Macro\input and \Macro\include hook, i.e.\ the \Macro\AtBeginOfFiles comes \emph{after} the \Macro\AtBeginOfIncludes and
+% the \Macro\AtEndOfFiles comes \emph{before} the \Macro\AtEndOfIncludes hook.
+%
+% The following figure shows the positions of the hooks inside the macro:\par\medskip
+% \centerline{\DrawInputIf{}}
+%
+%
+% \subsection*{Include Files}
+% \DescribeMacro{\AtBeginOfIncludes}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfIncludes}{<\TeX\ code>}
+% \DescribeMacro{\AfterIncludes}{<\TeX\ code>}
+% As described above the `AtEnd' hook is executed before and the `After' hook is executed after the trailing \Macro\clearpage.
+% Note that material which appears in the page header or footer should be updated in the `After' hook, not the `AtEnd' hook, to ensure
+% that the old values are still valid for the last page.
+%
+% \DescribeMacro{\AtBeginOfIncludeFile}{<file name>}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfIncludeFile}{<file name>}{<\TeX\ code>}
+% \DescribeMacro{\AfterIncludeFile}{<file name>}{<\TeX\ code>}
+% These file-specific macros take the two arguments. The \meta{code} is only executed for the file with the given \meta{file name}
+% and only if it is read using \Macro\include.
+% The \meta{file name} should be identical to the name used for \Macro\include and not include the `|.tex|' extension.
+% Files with a different extension are neither supported by \Macro\include nor this hooks.
+%
+% The following figure shows the positions of the hooks inside the macro:\par\medskip
+% \centerline{\hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\include:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\Macro\clearpage~~(implicit)}%
+% \hbox{\Hook{AtBeginOfEveryFile}}%
+% \hbox{\Hook{AtBeginOfIncludeFile}{<file name>}}%
+% \hbox{\Hook{AtBeginOfIncludes}}%
+% \hbox{\fbox{\DrawInputIfB{}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfIncludes}}%
+% \hbox{\Hook{AtEndOfIncludeFile}{<file name>}}%
+% \hbox{\Macro\clearpage~~(implicit)}%
+% \hbox{\Hook{AfterIncludes}}%
+% \hbox{\Hook{AfterIncludeFile}{<file name>}}%
+% \hbox{\Hook{AtEndOfEveryFile}}%
+% }}}%
+% }}}
+%
+%
+% \subsection*{Input Files}
+%
+% \DescribeMacro{\AtBeginOfInputs}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfInputs}{<\TeX\ code>}
+% Like the \Macro{...OfIncludes}{code} macros above, just for file read using \Macro\input.
+%
+% \DescribeMacro{\AtBeginOfInputFile}{<file name>}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfInputFile}{<file name>}{<\TeX\ code>}
+% Like the \Macro{...OfIncludeFile}{<file name>}{code} macros above, just for file read using \Macro\input.
+% If the \meta{file name} does not include a file extension it will be set to `|.tex|'.
+%
+% The following figure shows the positions of the hooks inside the macro:\par\medskip
+% \centerline{\hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\input:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\Hook{AtBeginOfEveryFile}}%
+% \hbox{\Hook{AtBeginOfInputFile}{<file name>}}%
+% \hbox{\Hook{AtBeginOfInputs}}%
+% \hbox{\fbox{\DrawInputIfB{}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfInputs}}%
+% \hbox{\Hook{AtEndOfInputFile}{<file name>}}%
+% \hbox{\Hook{AtEndOfEveryFile}}%
+% }}}%
+% }}}
+%
+%
+%
+% \subsection*{Package Files}
+%
+% \DescribeMacro{\AtBeginOfPackageFile}*{<package name>}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfPackageFile}*{<package name>}{<\TeX\ code>}
+% This macros install the given \MacroArgs<\TeX\ code> in the `AtBegin' and `AtEnd' hooks of the given package file.
+% The \Macro\AtBeginOfPackageFile simply executes \Macro\AtBeginOfFile{<package name>.sty}{<\TeX code>}.
+% Special care is taken to ensure that the `AtEnd' code is executed \emph{after} any code installed by the package itself
+% using the \LaTeX\ macro \Macro\AtEndOfPackage. Note that it is therefore executed after the `AtEndOfEveryFile' hook.
+% If the starred version is used and the package is already loaded the code
+% is executed right away.
+%
+% The following figure shows the positions of the hooks inside the macros:\par\medskip
+% \centerline{\hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\usepackage/\Macro\RequirePackage/\Macro\RequirePackageWithOptions:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\fbox{\DrawInputIf{\hbox{ (includes AtBeginOfPackageFile\MacroArgs{<file name>})}}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfPackage}~~(\LaTeX\ hook)}%
+% \hbox{\Hook{AtEndOfPackageFile}{<file name>}}%
+% }}}%
+% }}}
+%
+% \subsection*{Class Files}
+%
+% \DescribeMacro{\AtBeginOfClassFile}*{<class name>}{<\TeX\ code>}
+% \DescribeMacro{\AtEndOfClassFile}*{<class name>}{<\TeX\ code>}
+% This macros install the given \MacroArgs<\TeX\ code> in the `AtBegin' and `AtEnd' hooks of the given class file.
+% They work with classes loaded using \Macro\LoadClass, \Macro\LoadClassWithOptions and also \Macro\documentclass.
+% However, in the latter case |filehook| must be loaded using \Macro\RequirePackage beforehand.
+% The macro \Macro\AtBeginOfClassFile simply executes \Macro\AtBeginOfFile{<class name>.cls}{\ldots}.
+% Special care is taken to ensure that the `AtEnd' code is executed \emph{after} any code installed by the class itself
+% using the \LaTeX\ macro \Macro\AtEndOfClass.
+% Note that it is therefore executed after the `AtEndOfEveryFile' hook.
+% If the starred version is used and the class is already loaded the code
+% is executed right away.
+%
+% The following figure shows the positions of the hooks inside the macros:\par\medskip
+% \centerline{\hbox{\vbox{%
+% \sffamily
+% \hbox{\Macro\documentclass/\Macro\LoadClass/\Macro\LoadClassWithOptions:}%
+% \hbox{\fbox{\vbox{%
+% \hbox{\fbox{\DrawInputIf{\hbox{ (includes AtBeginOfClassFile\MacroArgs{<file name>})}}}}%
+% \vspace{2pt}%
+% \hbox{\Hook{AtEndOfClass}~~(\LaTeX\ hook)}%
+% \hbox{\Hook{AtEndOfClassFile}{<file name>}}%
+% }}}%
+% }}}
+%
+% \subsection{Clearing Hooks}
+% \DescribeMacro\ClearHook\AlsoMacro{At...Of...}<argument(s) of hook macro>
+% Using\marginpar{New in v0.5 2011/01/09} this macro existing hooks can be globally cleared, i.e.\ set to empty.
+% This should be used with care because it will also remove all (user level) hook code set
+% by packages into this hook.
+% Note that the special hook code installed by the packages \pkg{currfile} and \pkg{svn-multi}
+% as well as the compatibility code described in section~\ref{sec:comp} is not affected.
+% The syntax for this macro is the same as for the normal hook macros only with a leading \Macro\ClearHook,
+% where the \meta{code} argument is mandatory but its content is ignored.
+% Examples:\\
+% \hspace*{\bigskipamount}\Macro\ClearHook\AlsoMacro\AtBeginOfInputFile{<file name>}{<ignored>}\\
+% \hspace*{\bigskipamount}\Macro\ClearHook\AlsoMacro\AtBeginOfFiles{<ignored>}
+%
+%
+%
+% \clearpage
+% \section{PGF Key Interface}
+% An auxiliary package |pgf-filehook| is provided which adds support for the versatile \pkg{pgfkeys} interface.
+% This interface is heavily used by \pkg{pgf} (portable graphics format) and its higher level format Ti\textit{k}Z.
+% It allows the definition and execution of styles and commands (macros) using a \MacroArgs<key>'='<value> format.
+% Main benefits over similar formats is the support for a ``directory structure'' inside the key and the ability
+% to call functions on the value before it gets processed by the key. The main way to define and execute keys
+% is the macro \Macro\pgfkeys{<key>'='<value>',...'}. Ti\textit{k}Z provides the similar macro \Macro\tikzstyle
+% which defaults to the main path `|/tikz|'.
+% More detailed information can be found in the official |pgfmanual|.
+%
+% All |filehook| macros described in the previous section (\Macro{AtXXXOfYYY}) can also be accessed using the
+% pgf keys directory `|/filehook|', where all hook type have an own sub-directory (|/filehook/YYY|) in which
+% the hooks for this type are located (|/filehook/YYY/AtXXX|).
+% For example {\Macro\AtBeginOfInputs{<code>}} can also be
+% accessed using \\\hspace*{\parindent}\Macro\pgfkeys{'/filehook/Inputs/AtBegin='{<code>}}\\ or \Macro\AfterIncludeFile{<file name>}{<code>} as
+% \\\hspace*{\parindent}{\Macro\pgfkeys{'/filehook/IncludeFile/After='{<file name>}{<code>}}}\\ as well as
+% \Macro\AtEndOfClassFile*{<file name>}{<code>} as
+% \\\hspace*{\parindent}{\Macro\pgfkeys{'/filehook/ClassFile/AtEnd='*{<file name>}{<code>}}.}
+%
+% \DescribeMacro\pgffilehook{<key>'='<value>',...'}
+% This macro is like \Macro\pgfkeys but defaults to the `|/filehook|' directory, so that it can be dropped from the
+% \meta{key}. Note that |pgfkeys| also supports to ``change the directory'' using \MacroArgs<directory>'/.cd', so that
+% it does not need to be included in further keys. All directories are defined as `\textit{is family}' so that the |/.cd| is
+% assumed if the directory is used on its own.
+% For example\\\centerline{\Macro\pgfkeys{'/filehook/Inputs/AtBegin='{<code>}',/filehook/Inputs/AtEnd='{<code>}}}
+% can be shorten as\\\centerline{\Macro\pgffilehook{'Inputs,AtBegin='{<code>}',AtEnd='{<code>}}.}
+%
+% \medskip
+% Some of the pgf key functions can become useful, e.g.\ if the hook code should be expanded before it is added to the hook:\\
+% \hspace*{\parindent}\Macro\pgffilehook{'EveryFile/AtBegin/.expand once='{\AlsoMacro\headertext\space\AlsoMacro\currfilename}}\\
+% will expand the first macro \Macro\headertext\relax (actually the first token) in the hook code once (using \Macro\expandafter), but
+% not any other tokens. In this example future changes of \Macro\headertext would not have any effect on the hook code, but
+% \Macro\currfilename will be expanded for every file.
+% Other useful functions are `|.expand twice|' (expand the first token twice) and `|.expanded|' (expand the whole hook code using \Macro\edef).
+%
+% \clearpage
+% \section{Compatibility Issues with Classes and other Packages}\label{sec:comp}
+% The |filehook| package might clash with other packages or classes which also redefine \Macro\InputIfFileExists
+% or internal macros used by \Macro\include and \Macro\input\relax (which are \Macro\@input@ and \Macro\@iinput).
+% Special compatibility code is in place for the packages listed below (in their current implementation).
+% If any other unknown definition of \Macro\InputIfFileExists is found an error will be raised.
+% The package option `|force|' can be used to prevent this and to force the redefinition of this macro.
+% Then any previous modifications will be lost, which will most likely break the other package.
+% Table~\ref{tab:incomp} lists all packages and classes which where found do be incompatible.
+% The packages \pkg{auxhook}, \pkg{stampinclude}, \pkg{rerunfilecheck} and \pkg{excludeonly} redefine
+% one or more of the above macros but have been found compatible with |filehook|.
+% Please do not hesitate to inform the author of |filehook| of any encountered problems with other packages.
+%
+% \subsection{Supported Classes and Packages}
+% The following classes and packages are actively supported and should work as normal when used together with |filehook|.
+% Please note that most of them are incompatible to each other, which |filehook| might not fix.
+%
+% \subsubsection*{memoir}
+% The |memoir| class redefines \Macro\InputIfFileExists to add own hooks identical to the `At...OfFiles' hooks (there called \Macro\AtBeginFile and \Macro\AtEndFile).
+% This hooks will be moved to the corresponding ones of |filehook| and will keep working as normal.
+% Since v0.4 from 2011/01/03 this modification will be also applied when the |filehook| package is loaded (using \Macro\RequirePackage) \emph{before} the
+% |memoir| class. However, the hooks from |filehook| need to be temporally disabled while reading the |memoir| class.
+% They will not be triggered for all files read directly by this class, like configuration and patch files.
+% Note that the `At...OfClassFile' hooks still work for the |memoir| class file itself. In fact they are used to restore the default definition of \Macro\InputIfFileExists
+% at the begin and patch it at the end of the class file.
+% The |filehook| package should be loaded either before the class (using \Macro\RequirePackage) or directly
+% after it. Because the |memoir| hook code is moved to the |filehook| hooks this class should then be
+% compatible with below packages if |memoir| and |filehook| are loaded before them.
+%
+%
+% \subsubsection*{scrlfile}
+% The |scrlfile| package from the \emph{koma-script} bundle redefines \Macro\InputIfFileExists to allow file name aliases and to also add hooks.
+% If required it should be loaded before |filehook|, which will add its hooks correctly to the modified definition.
+% Since v0.4 from 2011/01/03 this modification will be also applied when the |scrlfile| package is loaded after |filehook|.
+%
+%
+% \subsubsection*{fink}
+% The |filehook| and |currfile| packages where written as replacements for the |fink| package, where |filehook| provides the necessary hooks for |currfile|.
+% The |fink| package has now been deprecated in favour of |currfile| and should not be used anymore. The |fink| compatibility code has been removed from |filehook|
+% and both cannot be used successfully together as both redefine the \Macro\InputIfFileExists macro.
+%
+%
+% \subsubsection*{listings}
+% The \pkg{listings} package uses \Macro\input inside \Macro\lstinputlisting. Therefore the |InputFile|(|s|) and |File|(|s|) hooks are also triggered for these files.
+% Please note that this hooks are executing inside a verbatim environment. While the code in the hook is not affected (because it was added outside the verbatim
+% environment), any further code read using any input macro (\Macro\input, \Macro\@input, \Macro\@@input\relax (\TeX's \Macro\input), \ldots) will be processed verbatim and typeset
+% as part of the listing.
+% Since v0.4 this macro is automatically patched so \Macro\@input is used instead to avoid this issue.
+%
+%
+% \subsection{Other Classes and Packages}
+%
+% \subsubsection*{jmlrbook}
+% The |jmlrbook| class from the |jmlr| bundle temporary redefines \Macro\InputIfFileExists to import papers.
+% The `original' definition is saved away at load time of the package and is used internally by the new definition.
+% This means that the hooks will not be active for this imported files because |filehook| is loaded after the class.
+% This should not affect its normal usage.
+% Note that, in theory, the package could be loaded before \Macro\documentclass using \Macro\RequirePackage to enable the file hooks also for these files.
+%
+% \subsubsection*{\LaTeX's \textbackslash bibliography}
+% The standard \LaTeX\ macro \Macro\bibliography uses the same internal macro \Macro\@input@ to read a file
+% as \Macro\include does.
+% The `include' hooks will also be executed for this |.bbl| file if the macro is directly followed by \Macro\clearpage,
+% because the |filehook| code will assume it is executed inside \Macro\include.
+% This rare case can be easily avoided by placing a \Macro\relax after \Macro\bibliography{\ldots}.

+% \section{Upgrade Guide}
+% \label{sec:upgrade}
+% This sections gives information for users of older versions of this package which unfortunately might not be 100\% backwards compatible.
+%
+% \subsection*{Upgrade to v0.4 - 2011/01/03}
+% \begin{itemize}
+% \item The macro \Macro\AfterIncludeFile was misspelled as \Macro\AfterOfIncludeFile in the implementation of earlier versions, but not in the documentation.
+% This has now be corrected. Please adjust your code to use the correct name and to require the |filehook| package from 2011/01/03.
+% \item All general hooks (the one not taking a file argument) used to have an implicit argument |#1| which was expanded to the file name (i.e.\ the argument of \Macro\input etc.).
+% This has now be changed, so that macro arguments are not handled special in hook code, which e.g.\ simplifies macro definitions.
+% Older hook code might need to change |##| to |#| to compensate for this change.
+% If the file name is required the macros (e.g.\ \Macro\currfilename) of the partner package \pkg{currfile} should be used.
+% These macros are available everywhere including in all hocks.

+% \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}

+% 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.
