In this article, I shall discuss some of the fundamental topics in
producing a structured document.  This document itself does not go into
much depth, but is instead the output of an example of how to implement
structure. Its \LaTeX{} source, when in used with my tutorial
provides all the relevant information.  \end{abstract}
This small document is designed to illustrate how easy it is to create a
well structured document within \LaTeX\cite{lamport94}.  You should quickly be able to
see how the article looks very professional, despite the content being
far from academic.  Titles, section headings, justified text, text
formatting etc., is all there, and you would be surprised when you see
just how little markup was required to get this output.
One of the great advantages of \LaTeX{} is that all it needs to know is
the structure of a document, and then it will take care of the layout
and presentation itself.  So, here we shall begin looking at how exactly
you tell \LaTeX{} what it needs to know about your document.
\subsection{Top Matter}
The first thing you normally have is a title of the document, as well as
information about the author and date of publication.  In \LaTeX{} terms,
this is all generally referred to as \emph{top matter}.
\subsubsection{Article Information}
%Set up an 'itemize' environment to start a bulleted list.  Each
%individual item begins with the \item command.  Also note in this list
%that it has two levels, with a list embedded in one of the list items.
	\item \texttt{\textbackslash title\{\emph{title}\}} - The title of the article.
	\item \texttt{\textbackslash date} - The date. Use:
			\item \texttt{\textbackslash date\{\textbackslash today\}} - to get the
			date that the document is typeset.
			\item \texttt{\textbackslash date\{\emph{date}\}} - for a  %\emph{} emphasises the specified text.  Italics by default.
			specific date.
			\item \texttt{\textbackslash date\{\}} - for no date.
\subsubsection{Author Information}
The basic article class only provides the one command:
	\item \texttt{\textbackslash author} - The author of the document.
It is common to not only include the author name, but to insert new
lines (\texttt{\textbackslash\textbackslash}) after and add things such
as address and email details.  For a slightly more logical approach, use
the AMS article class (\texttt{amsart}) and you have the following extra
	\item \texttt{\textbackslash address} - The author's address.  Use
	the new line command (\texttt{\textbackslash\textbackslash}) for
	line breaks.
	\item \texttt{\textbackslash thanks} - Where you put any acknowledgments.
	\item \texttt{\textbackslash email} - The author's email address.
	\item \texttt{\textbackslash urladdr} - The URL for the author's web page.
\subsection{Sectioning Commands}
The commands for inserting sections are fairly intuitive.  Of course,
certain commands are appropriate to different document classes.
For example, a book has chapters but a article doesn't.
%A simple table.  The center environment is first set up, otherwise the
%table is left aligned.  The tabular environment is what tells Latex
%that the data within is data for the table.
	\begin{tabular}{| l | l |} 
	%The tabular environment is what tells Latex that the data within is
	%data for the table.  The arguments say that there will be two
	%columns, both left justified (indicated by the 'l', you could also
	%have 'c' or 'r'.  The bars '|' indicate vertical lines throughout
	%the table.
		\hline  % Print horizontal line
		Command & Level \\ \hline  % Columns are delimited by '&'.  And
                                   %rows are delimited by '\\'
		\texttt{\textbackslash part\{\emph{part}\}} & -1 \\
		\texttt{\textbackslash chapter\{\emph{chapter}\}} & 0 \\
		\texttt{\textbackslash section\{\emph{section}\}} & 1 \\
		\texttt{\textbackslash subsection\{\emph{subsection}\}} & 2 \\
		\texttt{\textbackslash subsubsection\{\emph{subsubsection}\}} & 3 \\
		\texttt{\textbackslash paragraph\{\emph{paragraph}\}} & 4 \\
		\texttt{\textbackslash subparagraph\{\emph{subparagraph}\}} & 5 \\
Numbering of the sections is performed automatically by \LaTeX{}, so don't
bother adding them explicitly, just insert the heading you want between
the curly braces.  If you don't want sections number, then add an asterisk (*) after the
section command, but before the first curly brace, e.g., \texttt{\textbackslash
section*\{A Title Without Numbers\}}.
%Create the environment for the bibliography.  Since there is only one
%reference, set the label width to be one character (I shall follow
%convention as use the number '9'.  This is because it helps to remind
%that it is the maximum number of refs that is now permitted by that
%The \bibitem is to start a new reference.  Ensure that the cite_key is
%unique.  You don't need to put each element on a new line, but I did
%simply for readability.
