+% \section{Compatibility Issues with other Packages}
+% The |filehook| package might clash with other packages or classes which also redefine |\InputIfFileExists|.
+% Special compatibility code is in place for the known packages listed below (in their current implementation).
+% If any other unknown definition is found a warning will be printed and the macro will be overwritten.
+% Any previous modifications will be lost, which will most likely break the other package.
+% Please do not hesitate to inform the author of |filehook| of any encountered problems with other packages.
+%
+% \subsection*{jmlrbook}
+% The |jmlrbook| class from the |jmlr| bundle temporary redefines |\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 |\documentclass| using |\RequirePackage| to enable the file hooks also for these files.
+%
+% \subsection*{memoir}
+% The |memoir| class redefines |\InputIfFileExists| to add own hooks identical to the |At...OfFiles| hooks (there called |\AtBeginFile| and |\AtEndFile|).
+% This hooks will be moved to the corresponding ones of |filehook| and will keep working as normal.
+%
+% \subsection*{scrlfile}
+% The |scrlfile| package from the \emph{koma-script} bundle redefines |\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.
+%
+% \subsection*{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 |\InputIfFileExists| macro.
+%
+% \subsection*{listings}
+% The \pkg{listings} package uses |\input| inside \cs{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 (|\input|, |\@input|, |\@@input| (\TeX's |\input|), \ldots) will be processed verbatim and typeset
+% as part of the listing. A known package suffering from this is \pkg{svn-multi} which loads |.svx| files for every |.tex| file.
+% A workaround for this issue is to temporally redefine |\input| to |\@input| for \cs{lstinputlisting}: |{\let\input\@input\lstinputlisting{...}}|.
