+%\section{Introduction}
+%\label{sec:intro}
+%
+% Technical publications for Engineer Research and Development Center,
+% US Army Corps of Engineers follow an elaborate
+% style~\cite{ERDC_Guide}.  This style is accompanied by templates for
+% a popular word processor software.  In this class, commissioned by US
+% Army Corps of Engineers, we try to recreate this style for \LaTeX.
+%
+% There are several kinds of documents described by~\cite{ERDC_Guide}:
+% Technical Report, Technical Note, Miscellaneous Paper, Contract
+% Report, Letter Report, Monograph, Special Report, Brochure.  In this
+% class we follow the guidelines for Technical Reports (TR).  However,
+% it can be used for other kinds of documents as long as they do not
+% differ much from Technical Reports.  
+%
+%
+%\section{User Guide}
+%\label{sec:user_guide}
+%
+%
+%
+%\subsection{Installation}
+%\label{sec:ug_install}
+%
+% The class uses a number of \LaTeX{} packages.  Normally they should be
+% present in any up-to-date distribution.  If you do not have them,
+% you can download them using the links below prior to using the class.
+%
+% You will need \progname{PSFNSS}~\cite{Schmidt04:PSNFSS9.2}: the
+% \LaTeX{} package providing the access to common PostScript fonts.
+% Of course you will need the fonts themselves.  You will also need
+% \progname{graphics} bundle~\cite{Carlisle05:Graphics}, packages
+% \progname{geometry}~\cite{Umeki08:Geometry},
+% \progname{caption}~\cite{Sommerfeldt07:Caption},
+% \progname{longtable}~\cite{Carlisle04:Longtable}  and 
+% \progname{fancyhdr}~\cite{Oostrum04:Fancyhdr}.
+%
+%
+% The installation of the class follows the usual
+% practice~\cite{TeXFAQ} for \LaTeX{} packages:
+% \begin{enumerate}
+% \item Run \progname{latex} on |erdc.ins|.  This will produce the
+% \LaTeX{} class |erdc.cls|.
+% \item Put the files |erdc.cls|, |red_corps_castle2.eps| and
+%   |red_corps_castle2.pdf| to the place where \LaTeX{} can find it
+%   (see \cite{TeXFAQ} or the documentation for your \TeX{}
+%   system).\label{item:install}
+% \item Update the database of file names.  Again, see \cite{TeXFAQ}
+% or the documentation for your \TeX{} system for the system-specific
+% details.\label{item:update}
+% \item The file |erdc.pdf| provides the documentation for the
+% package (this is the file you are probably reading now).
+% \end{enumerate}
+% As an alternative to items~\ref{item:install} and~\ref{item:update}
+% you can just put the file |erdc.cls| in the working directory
+% where your |.tex| file is.
+%
+%
+%\subsection{Invocation}
+%\label{sec:ug_invocation}
+%
+% To use the class, put in the preamble of your document
+% \begin{flushleft}
+% |\documentclass[|\meta{options}|]{erdc}|
+% \end{flushleft}
+%
+% The class should work both with |latex| and |pdflatex| work flows.
+% Accordingly it is supplied with US Army Corps of Engineers in both
+% EPS and PDF formats.  
+%
+%
+% The class recoginzes the standard \LaTeX{} options, shared by the
+% most document classes~\cite{Lamport94}.
+% \DescribeOptions{8pt,9pt,10pt,11pt,12pt} The default font size
+% changing options (|8pt|, |9pt|, \dots, |12pt|) have no effect other
+% than producing a warning in the log since the font sizes of the
+% class are fixed by the guidelines~\cite{ERDC_Guide}. 
+%
+%
+%\subsection{Front Matter}
+%\label{sec:ug_frontmatter}
+%
+% \DescribeMacro{\frontmatter}.
+% The command |\frontmatter| starts the \emph{Front Matter} of the
+% document.  This part includes title page, table of contents, list of
+% figures, list of tables.
+%
+% \DescribeMacro{\laboratory}
+% The cover page of the Technical Report should have the center name
+% for Center-level reports or laboratory name for laboratory level
+% reports.  By default a technical report is assumed to be a
+% Center-level one, and the center name (Engineering Research and
+% Development Center) is printed in the cover page.  The macro
+% |\laboratory|\marg{Laboratory Name} overrides this default, for example:
+% \begin{verbatim}
+% \laboratory{Cold Regions Research and Engineering Laboratory}
+% \end{verbatim}
+% A line break command |\\| can be used inside this command to achieve
+% a desirable line break in the laboratory name if the automatic one
+% is not right.
+%
+% 
+% \DescribeMacro{\reportnum}
+% The command |\reportnum|\marg{Report Number} is used to store the
+% project number.  For example,
+% \begin{verbatim}
+% \reportnum{ERDC/CRREL SR-05-78}
+% \end{verbatim}
+% The report number should include the laboratory abbreviation as its
+% prefix.  
+%
+% \DescribeMacro{\program}
+% The command |\program|\marg{Program Title} is used to store the
+% title of the program.  For example,
+% \begin{verbatim}
+% \program{Military Engineering Technology}
+% \end{verbatim}
+% 
+% \DescribeMacro{\title} The command |\title| is used to store project
+% name:  |\title|\marg{Title}.  For example:
+% \begin{verbatim}
+% \title{A New Project}
+% \end{verbatim}
+% 
+% \DescribeMacro{\subtitle}
+% The command |\subtitle|\marg{Sub Title} us used to store the project
+% subtitle.  For example,
+% \begin{verbatim}
+% \subtitle{Model Investigation}
+% \end{verbatim}
+% 
+% \DescribeMacro{\date}
+% The macro |\date| stores the date of the document, for example
+% \begin{verbatim}
+% \date{March 2009}
+% \end{verbatim}
+%
+%
+% \DescribeMacro{\author}
+% \DescribeMacro{\affiliation}
+% \DescribeMacro{\and}
+% The macro |\author|\marg{Authors} stores the
+% names of authors that share the same affiliation.  The authors with
+% the same affiliation 
+% should be listed in the same |\author| macro, separated by the
+% keyword |\and|.  Do not put commas and the word ``and'' between the
+% authors' names:  \LaTeX{}
+% will take care of the proper punctuation.  The macro
+% |\affiliation|\marg{Affiliation} stores the affiliation of the
+% authors immediately preceding this command.  If a report is prepared
+% by several laboratories, or a laboratory and an outside contractor,
+% then you should list the authors with the same affiliation, then
+% show the affiliation, then repeat for the next affiliation.  For example:
+% \begin{verbatim}
+% \author{A. U. Thor \and C. O. R. Respondent \and C. O. Author}
+% \affiliation{Construction Engineering Research Laboratory\\
+%   U.S. Army Engineer Research and Development Center\\
+%   2902 Newmark Drive\\
+%   Champaign, IL 61826-9005}
+% \author{John M. Smith}
+% \affiliation{Coastal and Hydraulics Laboratory\\
+%   U.S. Army Engineer Research and Development Center\\
+%   3909 Halls Ferry Road\\
+%   Vicksburg, MS 39180-6199}
+% \end{verbatim}
+% Note that the guidelines~\cite{ERDC_Guide} do not say how to typeset
+% the authors that have several affiliations.  Accordingly we do not
+% deal with this case here.
+%
+% \DescribeMacro{\coverart}
+% It is recommended to put some artwork on the cover of the title
+% page.  It is set up by
+% the command |\coverart[|\meta{options}|]|\marg{file}.  The syntax of the
+% command is the same as the syntax of the command |\includegraphics|
+% of the \progname{graphicx} package~\cite{Carlisle05:Graphics}.  The
+% obligatory argument \marg{file} is the name of the graphics file
+% with the logo, and \oarg{options}, if present, may, for example, set
+% the dimensions of the graphics.  By default the graphics is scaled
+% to cover the full width of the page.  Note that our class uses the
+% ``extended'' version \progname{graphicx} of the package with its
+% ``key-value'' syntax.  For example,
+% \begin{verbatim}
+% \coverart[width=2in]{red_corps_castle2.eps}
+% \end{verbatim}
+% The format of the graphics file depends on the \TeX{} engine used.
+% If you use
+% \progname{latex}$\to$\progname{dvips}$\to$\progname{pstopdf} route,
+% then you need PostScript files (PS or EPS).  If you use
+% \progname{pdflatex} engine, then you need graphics files in JPEG,
+% PNG or PDF formats (see~\cite{TeXFAQ} for more information).
+%
+%
+% \DescribeMacro{\reporttype}
+% The type of the report is stored in the macro
+% |\reporttype|\marg{type}, for example:
+% \begin{verbatim}
+% \reporttype{Final Report}
+% \end{verbatim}
+% 
+% \DescribeMacro{\distribution}
+% All reports should have a distribution statement.  There are several
+% standard distribution statements, approved by  Department of Defense
+% Directive~5230.24~\cite{DoD5230.24}.  By default the reports have
+% Statement~A: \emph{Approved for public release; distribution is
+% unlimited.}  To change the default, use the macro
+% |\distribution|\marg{Distribution Statement}, for example
+% \begin{verbatim}
+% \distribution{Distribution authorized to U.S. Government Agencies
+% only; Test and Evaluation; November 2005.  Other requests should be
+% referred to U.S. Army Engineer Research and Development Center}
+% \end{verbatim}
+% 
+% \DescribeMacro{\preparedfor}
+% By default the reports have the phrase \emph{Prepared for U.S. Army
+% Corps of Engineers, Washington, DC 20314-1000} on the title page.
+% To change this designation, use the command |\preparedfor|, for
+% example,
+% \begin{verbatim}
+% \preparedfor{U.S. Army Engineer Research and Development Center\\
+% 3909 Halls Ferry Road, Vicksburg, MS 39180-6199} 
+% \end{verbatim}
+% To delete this phrase altogether, use |\preparedfor{}|.
+%
+% \DescribeMacro{\contractnum}
+% Contract or work unit number is set by |\contractnum| command, for example
+% \begin{verbatim}
+% \contractnum{Work Unit 33143}
+% \end{verbatim}
+% 
+% \DescribeMacro{\monitoredby}
+% Contract reports are monitored by a controlling laboratory.  Its
+% name and address is set by this command, for example
+% \begin{verbatim}
+% \monitoredby{U.S. Army Engineer Research and Development Center\\
+% 3909 Halls Ferry Road, Vicksburg, MS 39180-6199}
+% \end{verbatim}
+% 
+%
+%
+% \DescribeMacro{\additionalinfo}
+% The command |\additionalinfo|\marg{Additional Information} is used
+% to store additional information for the title page, for example,
+% \begin{verbatim}
+% \additionalinfo{Supercedes TR-2345-12345}
+% \end{verbatim}
+% 
+% \DescribeMacro{abstract}
+% The abstract of the report is set using the environment |abstract|:
+% \begin{verbatim}
+% \begin{abstract}
+%   This report disusses spins of electrons, protons and other
+%   fermions. 
+% \end{abstract}
+% \end{verbatim}
+% 
+% \DescribeMacro{\disclaimer}
+% By default all reports have the standard disclaimer.  If its text
+% should be changed for any reason, use the macro
+% |\disclaimer|\marg{New Disclaimer}, for example
+% \begin{verbatim}
+% \disclaimer{The contents of this report are not to be used for
+% advertising, publication, or promotional purposes. Citation of trade
+% names does not constitute an official endorsement or approval of the
+% use of such commercial products. All product names and trademarks
+% cited are the property of their respective owners. The findings of
+% this report are not to be construed as an official Department of the
+% Army position unless so designated by other authorized documents. 
+%
+% \textbf{DESTROY THIS REPORT WHEN NO LONGER NEEDED. DO NOT RETURN IT
+% TO THE ORIGINATOR.}}
+% \end{verbatim}
+% 
+%
+% \DescribeMacro{\maketitle}
+% The command |\maketitle| typesets the cover page, title page and
+% abstract page
+% of the report based on the data supplied by the macros above.  It
+% should therefore be issued \emph{after} these macros.
+%
+%
+% \DescribeMacro{\tableofcontents}
+% \DescribeMacro{\listoffigures}
+% \DescribeMacro{\listoftables}
+% \DescribeMacro{\listoffiguresandtables}
+% Table of contents is typeset with
+% the usual \LaTeX{} command~\cite{Lamport94} |\tableofcontents|.
+% This situation with the list of tables and the list of figures is
+% slightly more involved.  The guidelines~\cite{ERDC_Guide} require
+% the authors to combine the lists into the common list called
+% ``Figures and Tables'', which is subdivided into Figures and
+% Tables.  The heading of this joint list is a chapter heading, while
+% the headings of the sublists are on the section level.  However, the
+% guidelines say nothing about the situation where a report has only
+% figures or only tables.  Therefore we chose the following solution:
+% \begin{enumerate}
+% \item If you have \emph{both} figures and tables, use 
+%   |\listoffiguresandtables|.  It will automatically typeset both
+%   lists according to the requirements~\cite{ERDC_Guide}
+% \item If you have \emph{only} figures or \emph{only} tables, use either
+%   |\listoffigures| or |\listoftables| correspondingly.  In this case
+%   the heading will be typeset on the chapter level.
+% \item If you have neither (probably a rare situation), do not use
+%   any of these commands.
+% \end{enumerate}
+% 
+% \DescribeMacro{\chapter}
+% In the front matter the command |\chapter| produces an
+% \emph{unnumbered} chapter, so the commands |\chapter{Preface}| and
+% |\chapter*{Preface}|  give the same result (see also
+% Section~\ref{sec:ug_mainmatter} below).
+%
+%
+%\subsection{Main Matter}
+%\label{sec:ug_mainmatter}
+%
+% \DescribeMacro{\mainmatter}
+% The main matter starts with the macro |\mainmatter|.  The text is
+% divided into chapters, sections and subsections in the usual
+% \LaTeX{} manner. 
+% All familiar \LaTeX{} commands and packages should work without
+% problems.  Note that unlike articles, reports have chapters as the
+% highest subdivisions.  The chapters are numbered, while sections and
+% subsections are not.
+%
+% \DescribeMacro{\chapter}
+% \DescribeMacro{\chapter*}
+% One important difference between the standard \LaTeX{} and our class
+% is the following.  In standard \LaTeX{} the starred command
+% |\chapter*| produces an unnumbered chapter, that does not go into
+% the table of contents.  In our class \emph{all} chapters, numbered
+% or not, go into the table of contents.
+%
+% Tables should have the caption \emph{above} the tabular material
+% rather than below it as in standard \LaTeX.  The class automatically
+% sets the proper spacing for this arrangement, but it is the user's
+% responsibility to put the |\caption| command before the |tabular|
+% environment, for example
+% \begin{verbatim}
+% \begin{table}
+%   \centering
+%   \caption{Yearly Dividens}
+%   \label{tab:dividends}
+%   \footnotesize\sffamily
+%   \begin{tabular}{|l|r|}
+%     \hline
+%     \bfseries Year  & \bfseries Dividends, \%\\
+%     \hline
+%     1880  & 2.5  \\
+%     \hline
+%     1881  & 2.1  \\
+%     \hline
+%     1882  & 2.6  \\
+%     \hline
+%   \end{tabular}
+% \end{table}
+% \end{verbatim}
+% Note that the guidelines~\cite{ERDC_Guide} recommend excessive rules
+% in the tables, with borders around the cells, as shown in the
+% example above.  This is usually frowned upon in the good typesetting
+% practice.  
+%
+% The guidelines~\cite{ERDC_Guide} recommend use footnotesize sans
+% serif entries in the tables itself.  The class does \emph{not} do
+% this automatically:  the users should put |\footnotesize\sffamily|
+% before |\begin{tabular}|, as shown in the example above.
+% 
+% \DescribeMacro{\fbox}
+% The guidelines~\cite{ERDC_Guide} require the graphics to be
+% surrounded by a hairline box.  This is done by the standard |\fbox|
+% command, for example
+% \begin{verbatim}
+% \begin{figure}
+%   \centering
+%   \fbox{\includegraphics[width=3in]{plot}}
+%   \caption{Plot of $f(x)$}
+%   \label{fig:plot}
+% \end{figure}
+% \end{verbatim}
+% 
+%
+%\subsection{Back Matter}
+%\label{sec:ug_backmatter}
+%
+% \DescribeMacro{\appendix} 
+% Back matter in ERDC reports consists of
+% the bibliography, appendices and distribution forms.  The standard
+% \LaTeX{} command |\appendix| changes the numeration of chapters
+% according to the rules~\cite{ERDC_Guide}.  It should be issued after
+% the bibliography, but before the appendices.
+%
+% The guidelines~\cite{ERDC_Guide} do not formally specify all details
+% of bibliographies.  The authors are encouraged to use Bib\TeX{}
+% and \progname{natbib}~\cite{Daly07:Natbib} package for the creation
+% of professional-looking bibliographies. 
+% 
+% The reports should contain Form~298 (see, for example,
+% \url{http://www.ntis.gov/pdf/rdpform.pdf}).  This form should be
+% typeset separately.

+%    The general function to convert a list of items in the form
+%\begin{verbatim}
+% A\and B\and C\and D
+%\end{verbatim}
+%    to the form `A, B, C, and D' is \cs{xandlist}:

+% \xandlist{, }{ and }{, and }{A\and B\and C\and D}
+%\end{verbatim}
+%    This is a completely expandable macro, with the return value being
+%    the converted list. There is also a `no-execute' version whose
+%    fourth argument should be a macro; the text to be converted will be
