+% \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}
