+% \maketitle
+%
+% \begin{abstract}
+% Since PDF 1.5 portions of a page can be marked for better
+% accessibility support.
+% For example, replacement texts or expansions of abbreviations can be
+% provided. Package \xpackage{accsupp} starts with providing a minimal
+% low-level interface for programmers. Status is experimental.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% \subsection{Macros}
+%
+% Section ``10.8 Accessibility Support'' of the PDF reference
+% \cite{pdfspec} lists some features that can be added by
+% operators for marked content.
+%
+% \begin{declcs}{BeginAccSupp} \M{options}
+% \end{declcs}
+% It puts the operator |BDC| in the page stream:
+% \begin{quote}
+%   |/Span|\\
+%   |<<|\dots|>>| \qquad \textit{\% property dictionary}\\
+%   |BDC|
+% \end{quote}
+% The contents of the dictionary is controlled by \meta{options}.
+% See sections \ref{sec:feature} and \ref{sec:method}.
+%
+% \begin{declcs}{EndAccSupp} \M{options}
+% \end{declcs}
+% It puts the operator |EMC| in the page stream.
+% The only option is \xoption{pdfliteral}, see section \ref{sec:pdftex}.
+%
+% \bigskip
+% \noindent\textbf{Note:}
+% The caller is responsible for the placement of \cs{BeginAccSupp}
+% and \cs{EndAccSupp} pairs. Especially page breaks are not allowed
+% in between.
+%
+% \subsubsection{Feature options}\label{sec:feature}
+%
+% The PDF reference \cite{pdfspec} describes and explains the different
+% features. The names of the feature options are the same as the
+% key names for the property dictionary for operator |BDC|, see
+% \cs{BeginAccSupp}.
+%
+% \begin{description}
+% \item[\xoption{ActualText}:]
+%   Provides a replacement text, see examples in
+%   section \ref{sec:example}.
+% \item[\xoption{Alt}:]
+%   Provides an alternate description.
+% \item[\xoption{E}:]
+%   Provides the expansion of an abbreviation or an acronym.
+% \item[\xoption{Lang}:]
+%   Specifies the language.
+% \end{description}
+%
+% \subsubsection{Input methods}\label{sec:method}
+%
+% Except for \xoption{Lang} option \xoption{method} controls
+% how the argument for \xoption{ActualText}, \xoption{Alt},
+% and \xoption{E} are interpreted.
+% \begin{description}
+% \item[\xoption{method=plain}:]
+%   The string is only expanded and written without further
+%   treatment. Special characters are not protected, thus this method
+%   may result in an invalid PDF file.
+% \item[\xoption{method=escape}:]
+%   The string is expanded and special characters are escaped.
+%   The result is a valid PDF string.
+% \item[\xoption{method=hex}:]
+%   The string is given in hexadecimal notation.
+%   Section \ref{sec:example:notparallel} shows an example.
+% \item[\xoption{method=pdfstringdef}:]
+%   If package \xpackage{hyperref} is loaded, then its \cs{pdfstringdef}
+%   is used. This method is slow, but useful if the string contains
+%   arbitrary \hologo{TeX} code.
+% \item[\xoption{unicode}:]
+%   This option is needed, if the string is given as Unicode string
+%   (16 bit). Internally it adds the string prefix for Unicode.
+%   In case of \xoption{method=pdfstringdef} it passes the option
+%   to \cs{hypersetup}.
+% \end{description}
+%
+% \subsection{Workaround, option \xoption{space}}
+%
+% PDF specification says in ``10.8.3 Replacement Text''
+% \begin{quote}
+% Just as alternative descriptions can be provided for images and other
+% items that do not translate naturally into text (\dots), replacement
+% text can be specified for content that does translate into text but
+% that is represented in a nonstandard way. These nonstandard representations
+% might include, for example, glyphs for ligatures or custom characters, or
+% inline graphics corresponding to letters in an illuminated manustript or to
+% dropped capitals.
+% \end{quote}
+% However, the ActualText is ignored in Acrobat Reader
+% (until version 9 at least), if the content does not contain glyphs.
+% Option \xoption{space} adds such an invisible glyph, a space
+% character. The font name can be configured by option \xoption{spacefont},
+% the default font is \texttt{phvr8r}. The character slot is given
+% by option \xoption{spacechar}, default is \texttt{32}, the usual
+% position of the space character.
+%
+% These options can also be given as package options or in
+% macro \cs{AccSuppSetup} that takes a key value list as argument.
+% Usually only option \xoption{space} is necessary, if the
+% contents does not contain glyphs otherwise. Option \xoption{space}
+% is enabled by |space| or |space=true| and disabled by |space=false|.
+% It is disabled as default. The option is evaluated by \cs{BeginAccSupp}
+% and ignored by \cs{EndAccSupp}.
+%
+% Note: Even with option \xoption{space} I get sometimes wrong texts
+% when cut \& paste from AR7/Linux or AR8/Linux, e.g.
+% \begin{quote}
+%   |Hello| $\rightarrow$ |Helo|, |Helol|, |Hell|, \dots\\
+%   |Hello World| $\rightarrow$ |Helo WorldW|, |Helo World|, \dots
+% \end{quote}
+% I do not know what Acrobat Reader is doing here, thus feedback and
+% insights are welcome.
+%
+% \subsection{Driver options}
+%
+% Driver options are package options only.
+% The special \hologo{TeX} compilers \hologo{pdfTeX}, \hologo{LuaTeX} and \hologo{XeTeX}
+% are detected automatically. The default for unrecognized drivers can be
+% set by defining \cs{ActualTextDriverDefault}. This can be done
+% in the configuration file \xfile{accsupp.cfg}.
+%
+% \subsubsection{Option \xoption{pdftex}}\label{sec:pdftex}
+% Package option \xoption{pdftex} is used for \hologo{pdfTeX} in PDF mode.
+% Additionally \cs{BeginAccSupp} and \cs{EndAccSupp} understand
+% option \xoption{pdfliteral}. It controls
+% the modifier keyword for \cs{pdfliteral}:
+% \begin{quote}
+%   |pdfliteral=direct| $\Rightarrow$ |\pdfliteral direct{...}|
+% \end{quote}
+%
+% \subsubsection{Option \xoption{luatex}}\label{sec:luatex}
+% Package option \xoption{luatex} is used for \hologo{LuaTeX} in PDF mode.
+% Additionally \cs{BeginAccSupp} and \cs{EndAccSupp} understand
+% option \xoption{pdfliteral}. It controls
+% the modifier keyword for \cs{pdfextension} literal:
+% \begin{quote}
+%   |pdfliteral=direct| $\Rightarrow$ |\pdfextension literal direct{...}|
+% \end{quote}
+%
+% \subsubsection{Option \xoption{dvipdfm}}
+%
+% Package option \xoption{dvipdfm} and its aliases \xoption{dvipdfmx}
+% \xoption{xetex} are used for drivers that support
+% \textsf{dvipdfm} specials.
+%
+% \subsubsection{Option \xoption{dvips}}
+%
+% Package option \xoption{dvips} and its alias \xoption{dvipsone}
+% write pdfmark specials in the output. Unhappily these pdfmark
+% operators are ignored by \textsf{ghostscript} (latest tested
+% version is 8.54). Perhaps they are recognized by commercial
+% distiller applications.
+%
+% \subsubsection{Turning off page stream compression}
+%
+% For debugging it is useful to have uncompressed page stream objects.
+% This can be done afterwards via \textsf{pdftk}:
+% \begin{quote}
+%   |pdftk file.pdf output file-uncompressed.pdf uncompress|
+% \end{quote}
+% Or the PDF file is generated uncompressed:
+% \begin{description}
+% \item[\hologo{pdfTeX}:] |\pdfcompresslevel=0|
+% \item[dvipdfm:] |dvipdfm -z0 ...|
+% \item[dvipdfmx:] |dvipdfmx -z0 ...|
+% \item[ghostscript/ps2pdf:]
+%      |ps2pdf -dCompressPages=false input.ps output.pdf|
+% \end{description}

+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{accsupp}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/accsupp/accsupp.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/accsupp/accsupp.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `accsupp'
+% 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[\CTANinstall{install/macros/latex/contrib/accsupp.tds.zip}]
+% \end{description}
+% \emph{TDS} refers to the standard ``A Directory Structure
+% for \TeX\ Files'' (\CTANpkg{tds}). Directories
+% with \xfile{texmf} in their name are usually organized this way.
+%
+% \subsection{Bundle installation}
+%
+% \paragraph{Unpacking.} Unpack the \xfile{accsupp.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+%   |unzip accsupp.tds.zip -d ~/texmf|
+% \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 accsupp.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{accsupp.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 accsupp.dtx
+%makeindex -s gind.ist accsupp.idx
+%pdflatex accsupp.dtx
+%makeindex -s gind.ist accsupp.idx
+%pdflatex accsupp.dtx
+%\end{verbatim}
