% \section{Documentation}
%
% In January 2011 the mailing list lualatex-dev discussed
% ``quietening lualatex console output'' \cite{lualatex:quiet}.
% Inspired from this, I implemented this package \xpackage{hobsub}
% to load several packages in one file. The package is applied for
% two packages collections that are subsets of my package bundle
% \xpackage{oberdiek}.
% \begin{description}
% \item[\xpackage{hobsub-generic}] is a collection of packages
%   that can also be used with \hologo{plainTeX}.
% \item[\xpackage{hobsub-hyperref}] is a collection of packages
%   that is used by package \xpackage{hyperref}.
% \end{description}
%
% Package \xpackage{hobsub} provides the macros that
% are used in the collection packages and might be used
% in other projects as well. But there are many caveats,
% some of them are discussed below.
%
% The most serious problem is consistency. A package
% that is available as standalone package and is part
% of a collection might have different versions.
% Because my packages are organized in a bundle and should
% be installed and updated as bundle, the risk seems low
% to me. However, if a single package is updated manually, for
% example for testing, then it should be loaded before the
% collection that contains the package with an older version.
% In a collection, the package will not be loaded again if it
% is already loaded.
%
% \subsection{Usage}
%
% The collection packages \xpackage{hobsub-generic} and
% \xpackage{hobsub-hyperref} are loaded as usual:
% \begin{quote}
%  \begin{tabular}{@{}ll@{}}
%    |\usepackage{hobsub-generic}| & \hologo{LaTeX}\\
%    |\input hobsub-generic.sty| & \hologo{plainTeX}
%  \end{tabular}
% \end{quote}
% or
% \begin{quote}|\usepackage{hobsub-hyperref}|\end{quote}
% Of course, both \cs{usepackage} or \cs{RequirePackage}
% can be used.
%
% If you need requirements on the version date of a package
% inside a collection, then specify them afterwards, for
% example:
% \begin{quote}
%   |\usepackage{hobsub-generic}|\\
%   |\usepackage{ltxcmds}[2010/12/04]% |^^A
%   {\itshape |\ltx@ifblank is needed|}
% \end{quote}
%
% Also it is not garanteed that a package will be always
% part of a collection. Therefore it does not harm,
% to make the requirements explicite \emph{after}
% a collection is loaded, see the previous example.
% \hologo{LaTeX} knows that a
% package is already loaded and does not load it again.
%
% \subsection{Supported features}
%
% \begin{description}
% \item[No reloads:] If a package is already loaded then it
%  is not reloaded again if it is part of a collection package.
% \item[\cs{listfiles}:]
%   Each package that is loaded in a collection is also
%   added to the output of \cs{listfiles}.
% \item[\cs{@currname}, \cs{@currext}]
%   are updated, they are used by \hologo{LaTeX}'s
%  \cs{ProvidesPackage}.
% \item[\cs{AtEndOfPackage}:]
%   \hologo{LaTeX}'s hook mechanism that is used for
%   \cs{AtEndOfPackage} is supported. However none of the
%   packages in the collections are using \cs{AtEndOfPackage},
%   therefore this feature is completely untested.
% \end{description}
%
% \subsection{Common limitations}
%
% \begin{description}
% \item[\cs{endinput}:]
%   Often a package is using \cs{endinput}, either added by
%   \xpackage{docstrip}, or to stop package loading at an earlier
%   time. Therefore \cs{endinput} must be catched during package
%   loading to prevent that the collection package is closed
%   too early before reading all packages it contains.
%
%   This redefinition of \cs{endinput} fails if the package loads
%   other files that contain \cs{endinput}. To some degree it could
%   be catched by redefining macros that load files. But this will
%   not work for the primitive \cs{input}.
% \item[Options:]
%   \hologo{LaTeX}'s package options are not supported.
%   Therefore the packages that are put in a collection must
%   not support options.
% \item[Hook packages:]
%   Some packages and classes provides hooks for packages, see
%   packages \xpackage{scrlfile}, \xpackage{filehook}
%   or class \xclass{memoir}. These hooks are not supported
%   for embedded packages inside a collection package.
%   Because of the problem with \cs{endinput}, these hooks
%   are not supported. The hooks might contain code that
%   loads other files that execute \cs{endinput}.
% \end{description}
%
% \subsection{Package \xpackage{hobsub-generic}}
%
% \begin{TableList}[bp]{generic}\TableGeneric\end{TableList}
%
% Collection `generic' contains some of the \hologo{plainTeX} compatible
% packages of my bundle, see table \ref{tab:generic}.
% It adds the following restrictions to any package
% that is part of this collection:
% \begin{description}
% \item[Generic formats:] The following formats must be supported:
%   \hologo{LaTeX}, \hologo{plainTeX} and even \hologo{iniTeX}.
%   This applies to the collection package \xpackage{hobsub-generic}
%   the same way.
% \item[Prefixed macros:]
%   Any package of this collection should only define macros with
%   prefixed names to avoid name clashes. Resources like registers
%   must not be allocated and other global states should not be
%   changed except for added macro definitions.
% \end{description}
% Thus the package \xpackage{hobsub-generic} can also preloaded
% in the format file with \hologo{iniTeX}.
%
% \subsection{Package \xpackage{hobsub-hyperref}}
%
% \begin{TableList}[tp]{hyperref}\TableHyperref\end{TableList}
%
% Collection `hyperref' contains additional packages that are
% used by package \xpackage{hyperref} and that does not fit
% in collection `generic', see table{tab:hyperref}.
% The latter collection package
% \xpackage{hobsub-generic} is loaded via a conventional
% \cs{RequirePackage}.
%
% Because most of the packages in the collection `hyperref'
% needs \hologo{LaTeX}, the collection requires \hologo{LaTeX}.
%
% \subsection{Package \xpackage{hobsub}}
%
% This section is for advanced users that might want to
% build a collection package. Then it can be done by
% using \xpackage{hobsub}:
% \begin{quote}
%   \dots\\
%   |\RequirePackage{hobsub}[2011/04/23]|\\
%   \dots\\
%   |\hobsub@StartPackage{foo1}|\\
%   \textit{\dots\unskip\ package code of \xfile{foo1.sty} \dots}\\
%   |\endinput|\\
%   |<hobsub>|\\
%   |\hobsub@StopPackage|\\
%   |\hobsub@StartPackage{bar2}|\\
%   \textit{\dots\unskip\ package code of \xfile{bar2.sty} \dots}\\
%   |\endinput|\\
%   |<hobsub>|\\
%   |\hobsub@StopPackage|
%   \dots
% \end{quote}
% But be aware of the caveats and limitations, see above.
% Only quite a small portion of the packages can be embedded
% like this.

% \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/hobsub.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hobsub.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 hobsub.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}

% 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 hobsub.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{hobsub.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 hobsub.dtx
%makeindex -s gind.ist hobsub.idx
%pdflatex hobsub.dtx
%makeindex -s gind.ist hobsub.idx
%pdflatex hobsub.dtx
%\end{verbatim}
% \end{quote}
