+%
+% \begin{declcs}{hopatch@AfterPackage} \M{package} \M{patch code}
+% \end{declcs}
+%
+% will use the kernel \texttt{package/after/\meta{package}} hook if a
+% LaTeX format later then 2020/20/01 is detected. 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}.
+% \end{itemize}

+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{hopatch}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/hopatch/hopatch.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/hopatch/hopatch.pdf}] Documentation.

+%
+%
+%
+% \subsection{Package installation}
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+% \verb|tex hopatch.dtx|
+% \end{quote}
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):

+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution
+% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
+% these. For example, \TeX\,Live\ users run \verb|texhash| or
+% \verb|mktexlsr|.
+%
+% \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

+% \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}
