% \begin{abstract}
% This document describes the \textsf{aiaa} \LaTeX\ package that
% provides a \LaTeX\ class (\file{aiaa-tc.cls}) and \BibTeX\
% bibliography style file (\file{aiaa.bst}).
% The files in this package are used to create AIAA technical conference
% papers.
% The package also contains a users manual (you are looking at it) and
% two templates, a bare-bones sample and an advanced sample.
% \end{abstract}
%

%
% \section{Introduction}
%
% The AIAA class works by loading the standard \LaTeX\ article class and
% several LaTeX packages, and then making modifications and extensions
% to suit the AIAA layout requirements.\footnote{%
% The older, unofficial AIAA distribution that yields two-column layout
% is available in the distribution's `pre2004' subdirectory.}
% The AIAA \BibTeX\ style file was created with Daly's makebst program
% and then tweaked according to AIAA conventions.
% In addition, abbreviations for the AIAA journals and more common
% aerospace journals were added.
%
% \subsection{Requirements}
%
% To make use of the AIAA technical conferenece paper class and process
% the AIAA bare-bones template, you will need the following files:\\[3pt]
% \begin{tabular}{llll}
%  \cls{article.cls} &\pkg{graphicx.sty}&\pkg{array.sty}   &\pkg{setspace.sty}\\
%  \pkg{overcite.sty}&\pkg{lastpage.sty}&\pkg{fancyhdr.sty} 
% \end{tabular}\\[3pt]
% These should be included as part of your \TeX\ distribution.
% Note: \pkg{setspace} is only necessary if using the |submit| class
% option described below.
%
% To explore some of \LaTeX's more advanced features such as imbedded
% figures, tables with footnotes, hyperlinks, subfigures, dropped
% capitals at the beginning of paragraphs, automatic nomenclature
% collection and sorting, and bibliography generation that are
% demonstrated in the advanced template, you will need the following
% \LaTeX\ packages,\\[3pt]
% \begin{tabular}{rl}
%          \pkg{ifthen} & plain text conditionals \\
%         \pkg{dcolumn} & decimal-aligned tabular math columns \\
%        \pkg{fancyvrb} & extended verbatim environments \\
%       \pkg{subfigure} & subcaptions for subfigures \\
%         \pkg{nomencl} & nomenclature generation via Makeindex \\
%        \pkg{hyperref} & hyperlinks such as email or URLs \\
%  \pkg{threeparttable} & tables with footnotes \\
%         \pkg{wrapfig} & integrate figures and tables in text
%                         (i.e., DiVinci style) \\ 
%
%        \pkg{lettrine} & dropped capital letter at beginning of paragraph \\
%       \pkg{subfigmat} & matrices of similar subfigures, aka small multiples \\
%        \pkg{dropping} & an alternative dropped capital letter package
% \end{tabular}\\[3pt]
% \noindent The above packages are ordered according to the likelihood
% that they are included with any given \TeX\ distribution.
% The last three you will most likely have to download from CTAN
% (\href{http://www.ctan.org}{www.ctan.org}) and add to your \TeX\
% distribution according to its instructions for adding new packages, or
% just place them in your local working directory.
% Please see the Known Problems section before exploring the advanced example. 
%
% \subsection{User's Manual}
%
% A PDF version of this Users Manual is provided as part of the distribution.
% It was created by processing \file{aiaa.dtx} with \kbd{pdflatex}.
% Of course a PostScript version can be made by using \kbd{latex}.
%
% If you are new to LaTeX, you should first read {\it A (not so) Short
% Introduction to \LaTeX, or \LaTeX\ in 131 minutes}, which is
% available in a variety of languages from the Comprehensive \TeX\
% Archive Network (CTAN) website,
% \href{http://www.ctan.org/tex-archive/info/lshort/}%
%      {www.ctan.org/tex-archive/info/lshort/}.
%
% \subsection{Installation and Setup}
%
% If you have not already run \file{aiaa.ins} through \LaTeX{}, do so.
% The \pkg{docscript} utility (part of \LaTeX{}) will rip the code
% segments out of \file{aiaa.dtx} and save them in several files.
% If you encounter an error on installation like:\\[5pt]
% | ! Undefined control sequence|\\
% | \batchLine -> generate|\\
% |          {\file {aiaa-tc.cls}{\from{aiaa.dtx}{class}}}|\\
% |  1.728 \processbatchFile|\\[5pt]
% it means that your \pkg{docstrip} is very old and that you will need
% to update your \TeX\ distribution to take advantage of the AIAA package.
%
% Move \file{aiaa-tc.cls} to a directory searched by \TeX\footnote{%
% For a Unix te\TeX{} installation, a privileged user could
% put these files in a directory named something like
% \kbd{/usr/local/share/texmf/tex/latex/aiaa}\ for the entire site to
% use, remembering to run \kbd{texhash} to reconfigure te\TeX{} to
% search the new directory; or, a lowly user could make their own
% directory, e.g., \kbd{$\sim$/tex/inputs}, put the files in
% there, and set the environment variable \kbd{TEXINPUTS} via
% `\kbd{setenv TEXINPUTS $\sim$/tex/inputs:}'.
% The colon represents the system search path so, in this case, the user
% files take precedence.
% On a Mac or PC installation put these files in a folder named
% something like \file{TeX-inputs}.}
% and the file \file{aiaa.bst} to a directory searched by
% \BibTeX.\footnote{%
% Similar to preceding footnote, only on Unix, use the 
% environment variable \kbd{BSTINPUTS} for the bibliographic style file
% and \kbd{BIBINPUTS} for the bibliographic database; for Mac's, use the
% \file{BibTeX-inputs} folder, failing that try using the
% \file{TeX-inputs} folder.}
% Once things are installed, try to \LaTeX\ the bare-bones template.
% It should produce something similar to the existing PDF copy.
% 
% \section{Usage}
%
% The AIAA class is envoked by including\\[5pt]
% |   \documentclass[|{\itshape options}|]{aiaa-tc}|\\[5pt]
% at the beginning of your document.
% The AIAA class recognizes a |handcarry| option that places paper
% number, conference information, and copyright information in the paper
% when hand carrying papers to a ``loose papers'' conference, and a
% `submit' option that increases font size and line spacing.
% Other cptions are passed on to \LaTeX's \cls{article} class that is
% subsequently loaded by the AIAA class.\footnote{%
% For example, the \kbd{draft} option replaces figures with a
% labeled box of the appropriate size and graphically depicts lines that
% overrun the right margin (overfull boxes).} 
% The document is written just like one were using the standard \LaTeX{}
% \cls{article} document class; and thus, usage is well documented by
% others in various \LaTeX{} books~\cite{companion,guide,latex}.
% However, some of the stock commands have slightly different behaviors
% and there are a few new commands designed to make life a little brighter;
% these are discussed in the following sections.
%
% \subsection{General Commands}
%
% Several standard \LaTeX{} commands have been modified to behave
% slightly differently in the \cls{aiaa-tc} class.
% In addition, several new commands have been introduced to ease
% document preparation.
% Both types are discussed in the following subsections.
%
% \subsubsection{New Behavior from Standard Commands}
%
% \DescribeMacro{\date}
% \DescribeMacro{\maketitle}
% The \cls{aiaa-tc} class does not typeset the |\date| command as part of
% |\maketitle|.
% Standard \LaTeX{} behavior of |\maketitle| is to typeset the current
% date as part of the title section.
%  one would have to issue a command like, |\date{\vspace{-5ex}}|,
% to eliminate the date and removed the space created for it.
%
% \DescribeEnv{abstract}
% The |abstract| environment has been redefined within the \cls{aiaa-tc}
% class to produce slightly different typesetting.
% It now produces an indented block of text set in a smaller, bold font.
% This environment should be placed after your |\maketitle|.
% 
% \DescribeMacro{\section}
% \DescribeMacro{\subsection}
% \DescribeMacro{\subsubsection}
% \DescribeMacro{\paragraph}
% \DescribeMacro{\subparagraph}
% The counters, fonts, sizes, and positions normally produced by
% these commands have been modified to produce AIAA layout guidelines.
%
% \subsubsection{New Command}
%
% \DescribeMacro{\thanksibid}
% The command |\thanksibid| is very similar to the standard
% |\thanks| command which is used when footnoting
% the author affliations within the |\author| field.
% The distinction is that the |\thanksibid| command allows one
% to repeat a given footnote symbol without repeating the associated
% footnote text.  For example,\\[3pt]
% | \author{%|\\
% |  Peter Gnoffo,%|\\
% |   \thanks{Title, department, address, and member grade.}|\\
% |  Bil Kleb,%|\\
% |   \thanks{Title, department B, address, and member grade.}|\\
% |  Bill Wood,%|\\
% |   \thanksibid{2}%| \textit{use the same footnote as the second author.}\\
% |  \ and|\\
% |  Marge Myth%|\\
% |   \thanks{Title, department C, address, and member grade.}|\\
% | }|\\[3pt]
% Thus, |\thanksibid{2}| would only produce a footnote symbol
% at the end of Bill Wood's name and it would not generate
% any footnote text.
% Note that using the |\thanksibid| command does not increment the
% footnote counter, so for the case given above, an argument of |4|
% would not be a valid choice.
%
% \subsection{Hand Carry Information}
%
% \DescribeMacro{handcarry}
% The following commands are used to load information that is
% used by the |handcarry| class option.
% For example,\\[3pt]
% | \documentclass[handcarry]{aiaa-tc}|\\[3pt]
% The following commands are used produce appropriate headers and footers
% All of these commands are normally set in the preamble
% of your document (similar to |\author| and |\title|).\footnote{%
% The preamble is defined as anywhere between the 
% \cs{documentclass}\texttt{\string{\string}} and
% \cs{begin}\texttt{\string{document\string}} commands.}
%
% \DescribeMacro{\AIAApapernumber}
% \DescribeMacro{\AIAAconference}
% \DescribeMacro{\AIAAcopyright}
% The commands |\AIAApapernumber|, |\AIAAconference|, and |\AIAAcopyright|
% are used to put appropriate items in the header and footer of each page.
% The contents of |\AIAApapernumber| is placed in the footer while the
% contents of |\AIAAconference| is placed in the header.
% For example,\\[3pt]
% |  \AIAAapernumber{2004-3932}|\\
% |  \AIAAConference{16th AIAA Fluid Dynamics Conference,|\\
% |                  June 6--8, Portland, Oregon}|\\[3pt]
% A footnote describing the copyright conditions
% and other information about the document are incorporated via the
% |\AIAAcopyright|.
% This command should be loaded with one of the the copyright series
% of commands: |\CopyrightA|, |\CopyrightB|, |\CopyrightC|, or
% |\CopyrightD|, described below.
% To use, simply include something like the following in
% the your document's preamble:\\[3pt]
% |  \AIAAcopyright{\CopyrightA{2004}}|\\[3pt]
% \DescribeMacro{\CopyrightA}
% \DescribeMacro{\CopyrightB}
% \DescribeMacro{\CopyrightC}
% \DescribeMacro{\CopyrightD}
% \DescribeMacro{\CopyrightDAPL}
% where the specific copyright commands will expand to one of the standard AIAA
% forms: A, B, C, D, or D-APL.
% Note: they each have different arguments, or no arguments, depending
% on their requirements,\\[3pt]
% |  \CopyrightA{|\textit{year}|}|\\
% |  \CopyrightB{|\textit{year}|}{|\textit{full name or company}|}|\\
% |  \CopyrightC|\\
% |  \CopyrightD{|\textit{year}|}|\\
% |  \CopyrightDAPL{|\textit{year}|}|\\[3pt]
% See AIAA copyright instructions for which form to use.
%
% \subsection{Journal Submission}
%
% \DescribeMacro{submit}
% The |submit| option class option that is invoked as follows,\\[3pt]
% | \documentclass[submit]{aiaa-tc}|\\[3pt]
% \DescribeMacro{\AIAAsubmitinfo}
% will increase the font size and line spacing as well as place a
% running footer according to the contents of |\AIAAsubmitinfo|.
% For example,\\[3pt]
% | \AIAAsubmitinfo{Abbreviated Title, AuthorsLastName et al}|\\[3pt]
% will place an abbreviated title and the authors last name at the
% bottom of each page.
%
% \subsection{Making Modifications}
%
% If you feel the need to modify the behavior of items in
% \cls{aiaa-tc.cls}, simply cut the section you want to change and save
% it to a file named \file{myaiaamods.sty}.
% Then modify the code in \file{myaiaamods.sty} to suit your needs and
% include it in your document via |\usepackage{myaiaamods}| in the
% preamble.
%
% \subsection{Getting Help}
%
% For general questions related to AIAA papers, procedures, and guidelines,
% send email to
% \href{mailto:Paper_Tech_Support@AIAA.Org}{Paper\_Tech\_Support@AIAA.Org}.
% For help /specific/ to this AIAA \LaTeX\ distribution, send email to
% \href{mailto:LaTeX_Support@AIAA.Org}{LaTeX\_Support@AIAA.Org}.
%
% For general \LaTeX\ help, see the {\it The (not so) Short Introduction
% to \LaTeX} mentioned above, {\it \LaTeX: A Document Preparation
% System} (2nd ed.) by Lamport, and {\it The LaTeX Companion} (2nd ed.)
% by Mittelbach et al.~\cite{companion}
% For more specific \LaTeX\ help, do a Google `groups' search on the
% comp.text.tex USENET newsgroup and explore the \TeX\ User Group's frequently
% asked questions site last seen at
% \href{http://www.tex.ac.uk/cgi-bin/texfaq2html}%
%             {www.tex.ac.uk/cgi-bin/texfaq2html}.
% If these avenues fail to answer your question, read

%
% For an extensive guide to using Encapsulated PostScript in \LaTeX, see
% Keith Reckdahl's \file{epslatex} document available from CTAN's \file{info}
% directory,
% \href{http://www.ctan.org/tex-archive/info/}{www.ctan.org/tex-archive/info/}
% or various \LaTeX{} reference books.
%
% Especially helpful in locating various \LaTeX{} packages is
% the \kbd{Catalogue.html} web page found in the \file{help/Catalogue}
% directory of CTAN.
%
% \subsection{Known Problems}
% 
% The bibliographic style sheet |aiaa.bst| isn't fully tested; and thus,
% you may need to fiddle with your |.bbl| file for your final copy,
% i.e., edit |file.bbl| after running a \LaTeX{}, \BibTeX, \LaTeX\
% sequence, but before running \LaTeX{} the final time.
% Note: If you run \BibTeX\ after modifying |file.bbl|, you will lose
% your modifications when \LaTeX\ is run again.
%
% To typeset the advanced example, you will need a fairly complete \LaTeX{}
% distribution, and even then you will probably need to download packages
% like \pkg{dropping} or \pkg{lettine} as described in the Requirements
% section. 
% Also, some packages will need to be newer than 2002 or so.
% For example, older versions of the \pkg{nomenclature} package will
% given an error like\\[3pt]
% | ! Undefined control sequence.|
% | <argument> \nomitemsep |
% while older versions of the \pkg{geometry} package will give\\[3pt]
% | ERROR: Package keyval Error: No value specified for paper.|
%
% \subsection{Sending a Bug Report}
%
% Reports of bugs in the AIAA package are most welcome.
% Before filing a bug report, please take the following actions:
% \begin{enumerate}
%  \item Verify your problem is not due to your own input file(s)
%        styles sheet(s), or package(s);
%  \item Check to see if your problem is documented in the preceeding
%        section;
%  \item Try to isolate the problem by writing a {\it minimal} \LaTeX\
%        input file which reproduces the unexpected behavior and then:
%   \begin{enumerate}
%    \item Include the command\\
%          |     \setcounter{errorcontextlines}{50}|\\ 
%          in the preamble of your document to provide extra context when
%          things go awry;
%    \item Run your file through \LaTeX{};
%    \item Send a description of your problem, the input file and the
%          log file via e-mail to:
%          \href{mailto:LaTeX_Support@AIAA.Org?subject=bug}%
%               {LaTeX\_Support@AIAA.Org}. 
%  \end{enumerate}
% \end{enumerate}

% \section{Code Documentation}
%
% For the interested reader, the following sections can be made to
% contain a documented verion of the class code and bibliographic style file.
% These detailed coding bits are not included in the Users Manual by
% default.
% If you want to see these in typeset form, you need to comment
% out the |\OnlyDescription| line in the |<driver>| section of
% \file{aiaa.dtx} and process \file{aiaa.dtx} with (PDF)\LaTeX.
%
%    \begin{macrocode}
%<*driver>
\documentclass{ltxdoc}
 \usepackage[colorlinks]{hyperref}
 \OnlyDescription % comment out to typeset class and bibstyle code

% \subsection{The Class}
%
% First, the opening header:
%    \begin{macrocode}
%<*class>
%%
%%  `aiaa-tc.cls' - A LaTeX class to create AIAA technical conference papers.
%%
%%  The basic approach is to load the LaTeX article class and various
%%  standard LaTeX packages, and then make modifications and extensions to
%%  conform to AIAA's guidelines.
%%
%%  To use, simply select this class file in your LaTeX document.  For example,
%%
%%    \documentclass{aiaa-tc}
%%
%%  Class options:
%%
%%   handcarry - used for hand carrying a paper to a 'loose papers'
%%               conference.  It adds the conference name to the
%%               top of the first page, paper number to the bottom
%%               of each page, and a copyright notice on the bottom
%%               of the first
%%
%%   submit - produces output typically required for journal submission,
%%            i.e., 12pt font and 'double spacing'.
%%
%%  plus those accepted by the standard article class such as 'draft'.
%%
%%  Class-specific commands:
%%
%%   \thanksibid{} - Reuses \thanks footnote symbol from previous
%%                   author specified by position in \author command.
%%                   For example, `someone\thanksibid{2}' will reuse the
%%                   footnote symbol from the second author for 'someone'
%%                   without producing a repeated footnote at the bottom.
%%
%%   \AIAApapernumber{} - For use with 'handcarry' option.
%%    \AIAAconference{} - Ditto.
%%     \AIAAcopyright{} - Ditto.  Must be filled with one of the
%%                        various copyright types: \AIAAcopyrightA{year},
%%                        \AIAAcopyrightB{year}{holder}, \AIAAcopyrightC,
%%                        \AIAAcopyrightD{year}, or \AIAAcopyrightDAPL{year}.
%%
%%   \AIAAsubmitinfo{} - Footer information used by 'submit' option.
%%
%%  For support, further details, and a documented version of this class,
%%  please read the Users Manual, aiaa.pdf, and the templates that come
%%  with the AIAA LaTeX distribution.
%%
%%  Wish list:
%%
%%  o fine tune hyperref behavior, especially footnote behavior
%%
%%  o an \appendix command to switch section styles, counters, etc.
%%
%% o leave space for copyright notice so that handcarry option does
%%    not alter pagination.
%%
%    \end{macrocode}
