% The package provides an interface for selecting code depending
% on the options \xoption{draft} and \xoption{final}.

%
% \section{Usage}
%
% \subsection{Package loading}
%
% In order to detect the global class options \xoption{draft}
% and \xoption{final}, load this package somewhere after
% \cs{documentclass} without options:
% \begin{quote}
% |\usepackage{ifdraft}|
% \end{quote}
%
% \subsection{User macros}
%
% \begin{declcs}{ifdraft}\ \M{draft case} \M{final case}\\
%   \SpecialUsageIndex{\ifoptiondraft}^^A
%   \cs{ifoptiondraft}\ \M{option draft is given}\ ^^A
%                       \M{option draft is not given}\\
%   \SpecialUsageIndex{\ifoptionfinal}^^A
%   \cs{ifoptionfinal}\ \M{option final is given}\ ^^A
%                       \M{option final is not given}
% \end{declcs}
% If none of the options \xoption{draft} or \xoption{final} is used,
% then this package assumes \xoption{final} as default setting
% for \cs{ifdraft}. All classes that are known to me behave this way.
% (Otherwise you can find out with
% \cs{ifoptiondraft} and \cs{ifoptionfinal}, whether none of
% the options is set.)
%
% If either \xoption{draft} or \xoption{final} is used, \cs{ifdraft} is
% sufficient to distinguish between these cases.
%
% Both options \xoption{draft} and \xoption{final} should not be used
% at the same time. This is contradictionary input.
% Which option is more important? The result is
% unpredictable in general:
% \begin{itemize}
% \item
%   \xclass{article}, \xclass{report}, \xclass{book},
%   \xclass{scrartcl}, \xclass{scrreprt}, \xclass{scrbook}:\\
%   \xoption{draft}, \xoption{final}
%   $\rightarrow$ \xoption{final} is effective.\\
%   \xoption{final}, \xoption{draft}
%   $\rightarrow$ \xoption{final} is effective.\\
%   $\Rightarrow$ \xoption{final} wins, if given.
% \item
%   \xclass{memoir}:\\
%   \xoption{draft}, \xoption{final}
%   $\rightarrow$ \xoption{draft} is effective.\\
%   \xoption{final}, \xoption{draft}
%   $\rightarrow$ \xoption{draft} is effective.\\
%   $\Rightarrow$ \xoption{draft} wins if given.
% \end{itemize}
% These classes evaluates the options in declaration order.
% Because the declaration order of these options in this
% package is not really interesting, this packages evaluates
% the options in the order specified in the calling commands:
% \begin{itemize}
% \item
%   \xpackage{ifdraft}:\\
%   \xoption{draft}, \xoption{final}
%   $\rightarrow$ \cs{ifdraft} selects \xoption{final} clause.\\
%   \xoption{final}, \xoption{draft}
%   $\rightarrow$ \cs{ifdraft} selects \xoption{draft} clause.\\
%   $\Rightarrow$ latest given option wins.
% \end{itemize}
% Thus you know with \cs{ifdraft} the latest given option
% and you can emulate the behaviour of the different
% classes with the help of \cs{ifoptiondraft} and
% \cs{ifoptionfinal}.
%
% Summary: \cs{ifdraft} is sufficient to deal with the
% normal use cases: one or none out of \xoption{draft} and \xoption{final}.

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