%
% \section{Usage}
%    The package \Package{pagesel} is a \LaTeXe\ package:
%    \begin{quote}
%      |\usepackage|\oarg{options}|{pagesel}|
%    \end{quote}
%    (For plain\TeX\ and \LaTeX\,2.09 the similar package
%    \URL{\Package{selectp}}^^A
%    {https://ctan.org/pkg/selectp}
%    from \NameEmail{Donald Arsenau}{asnd@triumf.ca} can be used.)
%
%    Depending on the options the package works in two modes:
%    \begin{enumerate}
%    \item If no page selecting option is present, so the package
%          ignores the other options and finishes itself. So no
%          page will be suppressed by the package and auxiliary files
%          will be written.
%    \item With at least one page selecting option the specified
%          pages are selected and the other are suppressed.
%          The default for this mode is that auxiliary will not be
%          overwritten. (This can be changed by an option.)
%    \end{enumerate}
%
% \subsection{Page selecting}
%    The package \Package{pagesel} sets up a new counter that is
%    incremented by each \cmd{\shipout}.
%    In this way the package counts the output pages regardless the value
%    of the page counter. So each page can individually by addressed,
%    even if there are several pages with the same page number.
%
% \subsubsection{Options\texorpdfstring{ for selecting pages}{}}
%    \begin{description}
%    \item[\Option{odd}:] The output pages must have an odd number.
%         All even output pages are suppressed. If there are no
%         page areas specified so all odd pages are print. With
%         page areas only the odd pages in this areas are selected.
%    \item[\Option{even}:] The opposite of option \Option{odd}.
%    \item[Page area:] A page area consists of three elements:
%         the starting output page number, an ``area'' hyphen, and
%         the output page number of the last page in this area.
%         Each component is optional, so there are four kinds
%         to spezify a page area:
%         \begin{description}
%         \item[\meta{m}\Option{-}\meta{n}:] All pages between
%              \meta{m} and \meta{n} inclusive.
%         \item[\Option{-}\meta{n}:] All pages until \meta{n} inclusive.
%         \item[\meta{m}\Option{-}:] The page area starts with \meta{m}
%              and all pages to the end of document are selected.
%         \item[\Option{-}:] All pages (not very useful).
%         \item[\meta{s}:] The single page \meta{s}.
%         \end{description}
%    \end{description}
%
% \subsubsection{Examples}
%    \newcommand*{\exam}[1]{\texttt{\strut[#1]}}^^A hash-ok
%    \begin{tabular}{ll}
%      Options & Output pages\\
%      \hline
%      \exam{1, 4, 9}&  1, 4, and 9\\
%      \exam{7-10, 3}&  3, 7, 8, 9, and 10\\
%      \exam{odd, 3-6}& 3, and 5\\
%      \exam{-4, 3, even, 7-8}& 2, 4, and 8\\
%    \end{tabular}
%
% \subsection{Auxiliary files}
%    If a page is suppressed, the \cmd{\write} commands are not
%    performed. Labels, index entries, or entries for the
%    table of contents aren't written. So it is likely that
%    the table of contents, registers, and lists are incomplete.
% \subsubsection{Options\texorpdfstring{ for handling auxiliary files}{}}
%    \begin{description}
%    \item[\Option{nofiles}:] This is the default. Auxiliary files are
%         read but not written or changed. Also the job is aborted
%         after the last selected page for saving time.
%    \item[\Option{nonofiles}/\Option{files}:] Auxiliary files are
%         written.
%    \end{description}
% \subsubsection{\texorpdfstring{Package }{}\Package{hyperref}}
%    In old versions of \Package{hyperref} [1999/04/12 v6.55] (and below)
%    there is a bug with \cmd{\nofiles}:
%    \begin{itemize}
%    \item Some ``garbage'' appears on terminal and in the log file.
%          This is harmless and can be ignored.
%    \item The outline auxiliary file \cmd{\jobname.out}, however,
%          is opened and truncated to zero bytes.
%          Version 1.0 of this package had
%          loaded a patch file \File{hypnofil.tex}, if it detects
%          \Package{hyperref} to get \cmd{\nofiles} work.
%
%          With the new version of \Package{hyperref} [1999/04/13 v6.56]
%          \cmd{\nofiles} works now. Therefore the workaround code
%          is no longer needed and removed.
%    \end{itemize}

%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{pagesel}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/pagesel/pagesel.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/pagesel/pagesel.pdf}] Documentation.

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