Do\n%     not specify any graphic file extensions in your .tex file. This \n%     will allow us (later) to create a PDF version of the ThornGuide\n%     via pdflatex. |\n%   - References should be included with the latex \"bibitem\" command. \n%   - Use \\begin{abstract}...\\end{abstract} instead of \\abstract{...}\n%   - Do not use \\appendix, instead include any appendices you need as \n%     standard sections. \n%   - For the benefit of our Perl scripts, and for future extensions, \n%     please use simple latex.     \n%\n% *======================================================================* \n% \n% Example of including a graphic image:\n%    \\begin{figure}[ht]\n%       \\begin{center}\n%          \\includegraphics[width=6cm]{MyArrangement_MyThorn_MyFigure}\n%       \\end{center}\n%       \\caption{Illustration of this and that}\n%       \\label{MyArrangement_MyThorn_MyLabel}\n%    \\end{figure}\n%\n% Example of using a label:\n%   \\label{MyArrangement_MyThorn_MyLabel}\n%\n% Example of a citation:\n%    \\cite{MyArrangement_MyThorn_Author99}\n%\n% Example of including a reference\n%   \\bibitem{MyArrangement_MyThorn_Author99}\n%   {J.
