\title{A Simple Document}




A brief document to
illustrate how to use \LaTeX.


\section{The First Section}

This is a simple \LaTeX\ document.
Here is the first paragraph.
The next chapter is Chapter~\ref{ch:another}
and is on page~\pageref{ch:another}.
The next section is Section~\ref{sec:next}.

\begin{exercise}{An Example}
Here's an example exercise.

\section{The Next Section}

Here is the second paragraph\footnote{with a footnote}. 
As you can see it's a rather short paragraph, but not 
as short as the previous one. This document was 
created on: \today\ at \currenttime.

\chapter{Another Chapter}

Here's another very interesting chapter.
See Chapter~\ref{ch:intro} for an 
introduction. Our picture has turned
into Figure~\ref{fig:shapes}.

\caption{Some shapes}

\caption{Two Shapes: (\emph{a}) A Rectangle and
(\emph{b}) A Circle}

Figure~\ref{fig:shapes2} shows some more shapes.
Figure~\ref{fig:rectangle} is a rectangle and
Figure~\ref{fig:circle} shows a circle.

\begin{exercise}{Another Example}
Here's another example exercise.
