% Starting with this version
%
% \begin{declcs}{hopatch@AfterPackage} \M{package} \M{patch code}
% \end{declcs}
%
% will use a generic file hook from the kernel if a
% LaTeX format later then 2020/20/01 is detected 
% (\texttt{package/after/\meta{package}} in version 1.4, 
%  \texttt{package/\meta{package}/after} in version 1.5). 
% This can mean that the
% hook code is executed earlier than with version 1.3 (but always after the
% \meta{package}.
% If \meta{package} is already loaded, the \meta{patch code} is executed
% immediately. If an older format is detected if will fall back to the code of
% version 1.3.
%
% \section{Documentation for version 1.3}
%
% Sometimes I want to add code right after a package
% has been loaded. Examples are bug fixes, adaptations,
% or added features as needed by package \xpackage{hyperref},
% for instance.
%
% Unhappily \hologo{LaTeX} does not provide this kind of
% hook. \cs{AtEndOfPackage} can be used inside the package
% only, because \hologo{LaTeX} clears the hook right before
% it loads the package.
%
% However, there are already many packages and classes
% that provide hooks that are executed after the package
% is loaded, see table~\ref{tab:hooks}.
%
% \begin{table}[b]
% \caption{After package hooking}
% \label{tab:hooks}
% \begin{tabular}{ll}
% \bfseries Macro & \bfseries Provider\\
% \hline
% \cs{AfterPackage} & package \xpackage{scrlfile} \cite{scrlfile}\\
% \cs{AtEndOfPackageFile} & package \xpackage{filehook} \cite{filehook}\\
% \cs{AtEndPackage} & class \xclass{memoir} \cite{memoir}
% \end{tabular}
% \end{table}
%
% Package \xpackage{hopatch} can be used without the packages
% of table~\ref{tab:hooks}. But for an early executing right
% after a package is loaded, one of the following class or
% packages should be loaded before using \cs{hopatch@AfterPackage}:
% \begin{itemize}
%  \item package \xpackage{filehook}
%  \item package \xpackage{scrlfile}
%  \item class \xclass{memoir}
% \end{itemize}
%
% \begin{table}
% \caption{After begin document hooking}
% \begin{tabular}{ll}
% \bfseries Macro & \bfseries Provider\\
% \hline
% \cs{AtBeginDocument} & \hologo{LaTeX}'s kernel\\
% \cs{AtEndPreamble} & package \xpackage{etoolbox} \cite{etoolbox}\\
% \cs{AfterEndPreamble} & package \xpackage{etoolbox}
% \end{tabular}
% \end{table}
%
% Therefore I skip writing a new package for hooking into
% \hologo{LaTeX}'s package management and use this package
% to provide a wrapper to patch a package after it is loaded.
%
% \begin{declcs}{hopatch@AfterPackage} \M{package} \M{patch code}
% \end{declcs}
% If the package is already loaded, the \meta{patch code} is executed
% immediately.
% Otherwise the \meta{patch code} is stored in a command and tried
% at later locations until the package is available.
%
% The patch is tried in the following order:
% \begin{enumerate}
% \item If the package is already loaded, the patch is
%   applied immediately. Further locations are not tried.
% \item \cs{AtEndPackage}, provided by class \xclass{memoir} \cite{memoir},
%   and \cs{AfterPackage}, provided by package \xpackage{scrlfile} \cite{scrlfile},
%   are called right after the package file is input before
%   the hook of \hologo{LaTeX}'s \cs{AtEndOfPackage}.
% \item \cs{AtEndOfPackageFile}, provided by package \xpackage{filehook} \cite{filehook},
%   is called after the package is loaded and after the hook of
%   \hologo{LaTeX}'s \cs{AtEndOfPackage}.
% \item \cs{AtEndPreamble}, provided by package \xpackage{etoolbox} \cite{etoolbox},
%   is called at the beginning of |\begin{document}| before the hook
%   of \hologo{LaTeX}'s \cs{AtBeginDocument}.
% \item \cs{AtBeginDocument}, provided by \hologo{LaTeX}.
% \item \cs{AfterEndDocument}, provided by package \xpackage{etoolbox} \cite{etoolbox},
%   is called at the very end of |\begin{document}|. Preamble commands are
%   already forbidden there.
% \end{enumerate}
% Because of the various locations the patch code is restricted to
% limitations:
% \begin{itemize}
% \item
% Preamble commands, see \hologo{LaTeX}'s \cs{@onlypreamble}
% throw an error if used after |\begin{document}|. This is already
% the case for \cs{AfterEndDocument}. Therefore preamble commands
% are forbidden in the patching code.
% There are four exceptions \cs{@ifpackageloaded}, \cs{@ifclassloaded},
% \cs{@ifpackagelater} and \cs{@ifclasslater}. They are redefined
% during \cs{AfterEndDocument} using the counterparts of
% package \xpackage{ltxcmds} \cite{ltxcmds}.
% \item
% \cs{AfterPackage} of package \xpackage{scrlfile} and \cs{AtEndPackage}
% of class \xclass{memoir} call the hook before \hologo{LaTeX}'s
% \cs{AtEndOfPackage}.

% \subsection{Some details for the interested}
%
% \paragraph{Unpacking with \LaTeX.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip\ and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX\ for \docstrip\ (really,
% \docstrip\ does not need \LaTeX), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{hopatch.dtx}|
% \end{quote}
% Do not forget to quote the argument according to the demands
% of your shell.
%
% \paragraph{Generating the documentation.}
% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
% the documentation. The process can be configured by the
% configuration file \xfile{ltxdoc.cfg}. For instance, put this
% line into this file, if you want to have A4 as paper format:
% \begin{quote}
%   \verb|\PassOptionsToClass{a4paper}{article}|
% \end{quote}
% An example follows how to generate the
% documentation with pdf\LaTeX:
% \begin{quote}
%\begin{verbatim}
%pdflatex hopatch.dtx
%makeindex -s gind.ist hopatch.idx
%pdflatex hopatch.dtx
%makeindex -s gind.ist hopatch.idx
%pdflatex hopatch.dtx
%\end{verbatim}
% \end{quote}
