% \maketitle
%
% \begin{abstract}
% This package implements \pdfTeX's escape features
% (\cs{pdfescapehex}, \cs{pdfunescapehex}, \cs{pdfescapename},
% \cs{pdfescapestring}) using \TeX\ or \eTeX.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \begin{declcs}{EdefEscapeHex} \M{cmd} \M{string}\\
%  \cs{EdefUnescapeHex} \M{cmd} \M{string}\\
%  \cs{EdefEscapeName} \M{cmd} \M{string}\\
%  \cs{EdefEscapeString} \M{cmd} \M{string}
% \end{declcs}
% These commands converts \meta{string} and stores the result
% in macro \meta{cmd}. The conversion result is the same
% as the conversion of the corresponding \pdfTeX's primitives.
% Note that the argument \meta{string} is expanded before
% the conversion.
%
% For example, if \pdfTeX\ \textgreater= 1.30 is present,
% then \cs{EdefEscapeHex}
% becomes to:
% \begin{quote}
%\begin{verbatim}
%\def\EdefEscapeHex#1#2{%
%  \edef#1{\pdfescapehex{#2}}%
%}
%\end{verbatim}
% \end{quote}
% The package provides implementations for the case that \pdfTeX\ is
% not present (or too old). Even \eTeX\ can be missing, however it is
% used if it is detected.
%
% \paragraph{Babel.}
% The input strings may contain shorthand characters of package
% \xpackage{babel}.
%
% \subsection{Additional unescape macros}
%
% \begin{declcs}{EdefUnescapeName} \M{cmd} \M{string}
% \end{declcs}
% Sequences of a hash sign with two hexadecimal digits are
% converted to the corresponding character (PDF-1.2).
% A hash sign that is not followed by two hexadecimal digits
% is left unchanged. The catcodes in the result string follow
% TeX's conventions. The space has catcode 10 (space) and
% the other characters have catcode 12 (other).
%
% \begin{declcs}{EdefUnescapeString} \M{cmd} \M{string}
% \end{declcs}
% Macro \meta{cmd} stores the unescaped string in \meta{string}.
% All the rules for literal strings are implemented, see
% PDF specification.
% The catcodes in the result string follow TeX's conventions.
%
% \subsection{Sanitizing macro}
%
% \begin{declcs}{EdefSanitize} \M{cmd} \M{string}
% \end{declcs}
% Argument \meta{string} is expanded, converted to a string
% of tokens with catcode 12 (other) and space tokens, and
% stored in macro \meta{cmd}.

% 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/pdfescape.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{pdfescape.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip pdfescape.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 pdfescape.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
% (\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{pdfescape.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 pdfescape.dtx
%makeindex -s gind.ist pdfescape.idx
%pdflatex pdfescape.dtx
%makeindex -s gind.ist pdfescape.idx
%pdflatex pdfescape.dtx
%\end{verbatim}
