%
% This package suppresses page numbers and headings from appearing
% on empty pages. The code for doing this is not mine and already
% exists in various places; all I've done is create a convenient
% stand-alone package for it.
%
% \section{Usage}
%
% Just include the package!
%
% \section{Package options}
%
% \begin{description}
% \item[odd] (default) The next non-empty page will be an odd-numbered page.
% \item[even] The next non-empty page will be an even-numbered page.
% \end{description}
%
% \StopEventually{}
%
% \section{Implementation}
%
% Create an empty page:
%    \begin{macrocode}
\def\emptypage@emptypage{%
    \hbox{}%
    \thispagestyle{empty}%
    \newpage%
    \if@twocolumn%
        \hbox{}%
        \newpage%
    \fi%
}
%    \end{macrocode}
%
% Implement \textbf{odd}:
%    \begin{macrocode}
\DeclareOption{odd}{
    \def\cleardoublepage{%
        \clearpage%
        \if@twoside%
            \ifodd\c@page%
                % do nothing
            \else%
                \emptypage@emptypage%
            \fi%
        \fi%
    }
}
%    \end{macrocode}
%
% Implement \textbf{even}:
%    \begin{macrocode}
\DeclareOption{even}{
    \def\cleardoublepage{%
        \clearpage%
        \if@twoside%
            \ifodd\c@page%
                \emptypage@emptypage%
            \else%
                % do nothing
            \fi%
        \fi%
    }
}
%    \end{macrocode}
%
% Default to \textbf{odd}:
%    \begin{macrocode}
\ExecuteOptions{odd}
%    \end{macrocode}
%
% Process options:
%    \begin{macrocode}
\ProcessOptions
%    \end{macrocode}
%
% \Finale
