% \section{Documentation}
%
% \subsection{Introduction}
%
% Especially since \eTeX\ there are many integer values
% with special meanings, such as catcodes, group types, \dots
% Package \xpackage{etex}, enabled by options, defines
% macros in the user namespace for these values.
%
% This package goes another approach for storing the names and values.
% \begin{itemize}
% \item If \LuaTeX\ is available, they
% are stored in Lua tables.
% \item Without \LuaTeX\ they are remembered using internal
% macros.
% \end{itemize}
%
% \subsection{User interface}
%
% The integer values and names are organized in a hierarchical
% scheme of categories with the property names as leaves.
% Example: \eTeX's \cs{currentgrouplevel} reports |2| for a
% group caused by \cs{hbox}. This package has choosen to organize
% the group types in a main category |etex| and its subcategory
% |grouptype|:
% \begin{quote}
%   |etex.grouptype.hbox| = |2|
% \end{quote}
% The property name |hbox| in category |etex.grouptype| has value |2|.
% Dots are used to separate components.
%
% If you want to have the value, the access key is constructed by
% the category with all its components and the property name.
% For the opposite the value is used instead of the property name.
%
% Values are always integers (including negative numbers).
%
% \subsubsection{\cs{magicnum}}
%
% \begin{declcs}{magicnum} \M{access key}
% \end{declcs}
% Macro \cs{magicnum} expects an access key as argument and
% expands to the requested data. The macro is always expandable.
% In case of errors the expansion result is empty.
%
% The same macro is also used for getting a property name.
% In this case the property name part in the access key is
% replaced by the value.
%
% The catcodes
% of the resulting numbers and strings follow \TeX's tradition of
% \cs{string}, \cs{meaning}, \dots: The space has catcode 10
% (|tex.catcode.space|) and the other characters have catcode
% 12 (|tex.catcode.other|).
%
% Examples:
% \begin{quote}
%   |\magicnum{etex.grouptype.hbox}| $\Rightarrow$ |2|\\
%   |\magicnum{tex.catcode.14}| $\Rightarrow$ |comment|\\
%   |\magicnum{tex.catcode.undefined}| $\Rightarrow$ $\emptyset$
% \end{quote}
%
% \subsubsection{Properties}
%
% \begin{itemize}
% \item The components of a category are either subcategories or
%       key value pairs, but not both.
% \item The full specified property names are unique and thus
%       has one integer value exactly.
% \item Also the values inside a category are unique.
%       This condition is a prerequisite for the reverse mapping
%       of \cs{magicnum}.
% \item All names start with a letter. Only letters or digits
%       may follow.
% \end{itemize}

% \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/magicnum.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/magicnum.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 magicnum.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
% (\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 magicnum.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{magicnum.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 magicnum.dtx
%makeindex -s gind.ist magicnum.idx
%pdflatex magicnum.dtx
%makeindex -s gind.ist magicnum.idx
%pdflatex magicnum.dtx
%\end{verbatim}
% \end{quote}
