% \begin{abstract}
% This packages provides a wrapper to various package hooks
% provided by other packages or classes, but does not define
% own hooks.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% 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}
% \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}.

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{ftp://ftp.ctan.org/tex-archive/}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/hopatch.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hopatch.pdf}] Documentation.
% \end{description}
%
%
% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
% are also available in a TDS compliant ZIP archive. There
% the packages are already unpacked and the documentation files
% are generated. The files and directories obey the TDS standard.
% \begin{description}
% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories
% with \xfile{texmf} in their name are usually organized this way.
%
% \subsection{Bundle installation}
%
% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
% |unzip oberdiek.tds.zip -d ~/texmf|
% \end{quote}
%
% \paragraph{Script installation.}
% Check the directory \xfile{TDS:scripts/oberdiek/} for
% scripts that need further installation steps.
% Package \xpackage{attachfile2} comes with the Perl script
% \xfile{pdfatfi.pl} that should be installed in such a way
% that it can be called as \texttt{pdfatfi}.
% Example (linux):
% \begin{quote}
% |chmod +x scripts/oberdiek/pdfatfi.pl|\\
% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
% \end{quote}
%
% \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):
% \begin{quote}
% \def\t{^^A
% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}
% hopatch.sty & tex/latex/oberdiek/hopatch.sty\\
% hopatch.pdf & doc/latex/oberdiek/hopatch.pdf\\

% 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
% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \teTeX\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Attached source.}
%
% The PDF documentation on CTAN also includes the
% \xfile{.dtx} source file. It can be extracted by
% AcrobatReader 6 or higher. Another option is \textsf{pdftk},
% e.g. unpack the file into the current directory:
% \begin{quote}
% \verb|pdftk hopatch.pdf unpack_files output .|
% \end{quote}
%
% \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}
