+% *======================================================================*
+%  Cactus Thorn template for ThornGuide documentation
+%  Author: Ian Kelley
+%  Date: Sun Jun 02, 2002
+%  $Header: /home/eschnett/C/carpet/Carpet/CarpetExtra/WaveToyFO/doc/documentation.tex,v 1.1 2003/06/18 18:24:30 schnetter Exp $                                                             
+%
+%  Thorn documentation in the latex file doc/documentation.tex 
+%  will be included in ThornGuides built with the Cactus make system.
+%  The scripts employed by the make system automatically include 
+%  pages about variables, parameters and scheduling parsed from the 
+%  relevent thorn CCL files.
+%  
+%  This template contains guidelines which help to assure that your     
+%  documentation will be correctly added to ThornGuides. More 
+%  information is available in the Cactus UsersGuide.
+%                                                    
+%  Guidelines:
+%   - Do not change anything before the line
+%       % START CACTUS THORNGUIDE",
+%     except for filling in the title, author, date etc. fields.
+%        - Each of these fields should only be on ONE line.
+%        - Author names should be sparated with a \\ or a comma
+%   - You can define your own macros, but they must appear after
+%     the START CACTUS THORNGUIDE line, and must not redefine standard 
+%     latex commands.
+%   - To avoid name clashes with other thorns, 'labels', 'citations', 
+%     'references', and 'image' names should conform to the following 
+%     convention:          
+%       ARRANGEMENT_THORN_LABEL
+%     For example, an image wave.eps in the arrangement CactusWave and 
+%     thorn WaveToyC should be renamed to CactusWave_WaveToyC_wave.eps
+%   - Graphics should only be included using the graphix package. 
+%     More specifically, with the "includegraphics" command. Do
+%     not specify any graphic file extensions in your .tex file. This 
+%     will allow us (later) to create a PDF version of the ThornGuide
+%     via pdflatex. |
+%   - References should be included with the latex "bibitem" command. 
+%   - Use \begin{abstract}...\end{abstract} instead of \abstract{...}
+%   - Do not use \appendix, instead include any appendices you need as 
+%     standard sections. 
+%   - For the benefit of our Perl scripts, and for future extensions, 
+%     please use simple latex.     
+%
+% *======================================================================* 
+% 
+% Example of including a graphic image:
+%    \begin{figure}[ht]
+% 	\begin{center}
+%    	   \includegraphics[width=6cm]{MyArrangement_MyThorn_MyFigure}
+% 	\end{center}
+% 	\caption{Illustration of this and that}
+% 	\label{MyArrangement_MyThorn_MyLabel}
+%    \end{figure}
+%
+% Example of using a label:
+%   \label{MyArrangement_MyThorn_MyLabel}
+%
+% Example of a citation:
+%    \cite{MyArrangement_MyThorn_Author99}
+%
+% Example of including a reference
+%   \bibitem{MyArrangement_MyThorn_Author99}
+%   {J. Author, {\em The Title of the Book, Journal, or periodical}, 1 (1999), 
+%   1--16. {\tt http://www.nowhere.com/}}
