%
% In other words, by default .eps files will be automatically
% converted to .pdf files when outputting pdf.  This can be wrong!
% If the .pdf is the source, rather than the .eps, you should put
%  \newcommand{\DoNotLoadEpstopdf}{}
% before even the \documentclass line of your document.
%
% Earlier versions did not load epstopdf if shell escape was disabled.
% Now load, for better error reporting and to allow inclusion of pre-existing
% converted files: see gh/38
%
% More information about the epstopdf run will be in the .log file;
% see http://ctan.org/pkg/epstopdf-pkg for more info about the
% epstopdf package itself.  In turn, it calls the epstopdf script
% (http://ctan.org/pkg/epstopdf).
