-% \section{Introduction}
-%
-% A re-implementation of Heiko Oberdiek's \textsf{ifpdf} package
-% with simplified structure and updated to work with current Lua\TeX.
-%
-% The package defines a new boolean, \verb|\ifpdf| which is true
-% for pdf\TeX\ and Lua\TeX\ in PDF mode, and false otherwise.
-%
-% \section{Implementation}

-% \begin{macrocode}
-%<*package>
-% \end{macrocode}
-%
-% If \verb|\ifpdf| is not defined define it, taking care that it is
-% outer in plain \TeX.
-% \begin{macrocode}
-\expandafter\ifx\csname ifpdf\endcsname\relax
- \csname newif\expandafter\endcsname\csname ifpdf\endcsname
-\else
-% \end{macrocode}
-% If \verb|\ifpdf| is already defined but \verb|\pdftrue| is not defined
-% give up.
-% \begin{macrocode}
- \ifx\pdftrue\undefined
- \ifx\PackageError\undefined
- \begingroup\def\PackageError#1#2#3{\endgroup\errmessage{#2}}
- \fi
- \PackageError{ifpdf}{incompatible ifpdf definition}{}
- \expandafter\expandafter\expandafter
- \fi
-\fi
-% \end{macrocode}
-% Otherwise set the boolean to false unless pdfoutput (outputmode) is greater than zero.
-% For Lua\TeX, do the test in Lua as the tex primitivies may not be enabled, and
-% the primitive name may be \verb|\pdfoutput| or \verb|\outputmode| depending
-% on the Lua\TeX\ version number.
-% \begin{macrocode}
-\let\ifpdf\iffalse
-% \end{macrocode}
