% \maketitle
%
% \begin{abstract}
% Starting with \texlive 2010, the various formats that directly generate PDF
% default to PDF 1.5. While this allows for more compact documents thanks to
% objects compression, it can also lead to compatibility issues with some
% older PDF viewers.\footnote{For reference, Adobe Reader 6.0, released in
% 2003, was the first reader to handle PDF 1.5.} This package changes back the
% version of generated PDF to 1.4 with formats based on pdf\TeX{} or Lua\TeX\
% in PDF mode, for documents that need to achieve maximal compatibility with
% old viewers.
%
% If you need to generate maximally compatible documents, you may also be
% interested in the \pf{pdfx} package.
% \end{abstract}
%
% \section{Documentation}
%
% Just load this package, preferably right after the \verb+\documentclass+
% command. That's it. The rest of this documentation describes possible
% problems that may arise under particular circumstances.
%
% The \pf{pdf14} package should be loaded as early as possible in order to
% avoid problems. If you run into an error like:
% \begin{verbatim}
% ! pdfTeX error (setup): \pdfminorversion cannot be changed after data is
% written to the PDF file.
% \end{verbatim}
% it probably means that some package loaded before \pf{pdf14} did write data
% to the PDF file. In case the document class is (indirectly) doing it, you'll
% need to load \pf{pdf14} even before the \verb+\documentclass+ command, using
% \verb+\RequirePackage{pdf14}+ as the first line of your source file.
%
% Also, another package might try to set the PDF version itself, likely because
% it is going to use some advanced PDF features. Currently, no check for this
% is done by \pf{pdf14} to guard against this. So, it is your responsibility
% to check that the document produced are actually PDF 1.4.\footnote{You may
% do so using \texttt{pdfinfo} from the Xpdf distribution, or the
% File$\to$Properties menu of Acrobat Reader.} Future versions of \pf{pdf14}
% may include such a check, but it could only guarantee that the
% \emph{declared} PDF version has not been changed, not that the file produced
% is actually correct PDF 1.4.\footnote{Unfortunately, some packages are known
% to use features available only in PDF 1.5 and greater without properly
% setting the declared PDF version.}
%
% \section{Implementation}
%
% \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{pdf14}[2010/03/26 v0.1 Generate PDF 1.4 documents (mpg)]
% \end{macrocode}
%
% Check if we are running pdf\TeX\ or Lua\TeX\ in PDF mode. If not, issue
% an information message and exit. Since we address only \LaTeX-based
% formats in \texlive, we can assume that \verb|\pdfoutput| is available.
% (We don't load \pf{ifpdf} in order to avoid loading too many packages
% before \verb+\documentclass+.)
%
% \begin{macrocode}
\begingroup

You are not running pdfTeX (or LuaTeX) in PDF mode.\MessageBreak
Package pdf14 is useless in this case. Skipping.}%

% 1.4 (see the Makefile).
