+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\begin{abstract}
+  \texttt{pgf-pie} is a LaTeX package for drawing pie chart. As stated
+  by its name, it is based on a very popular graphic package
+  \texttt{PGF/TikZ}. This document presents the usage of
+  \texttt{pgf-pie} and collects some pie charts as examples.
+  \texttt{pgf-pie} can be downloaded from
+  \href{http://code.google.com/p/pgf-pie/}{http://code.google.com/p/pgf-pie/}.
+\end{abstract}
+
+\tableofcontents
+
+\section{The Essentials}
+
+\subsection{First Pie}
+\demo[0.6]{first-pie}
+
+\subsection{Polar area diagram}
+The polar area diagram is similar to a usual pie chart, except sectors
+are equal angles and differ rather in how far each sector extends from
+the center of the circle.
+
+\demo[0.6]{polar}
+
+\subsection{Position, Rotation, Size}
+
+The center of chart can be set by \texttt{pos}, default is
+\texttt{\{0,0\}}. The chart can be rotated by setting \texttt{rotate}
+(in degrees). The size of chart can be set by \texttt{radius}, default
+is 3.
+
+\demo{radius}
+
+\subsection{Explode}
+\demo{explode}
+
+\subsection{Text Label}
+
+\subsubsection{Text inside pie}
+\demo[0.6]{before-after-number}
+
+\subsubsection{Text outside pie}
+The value of \texttt{text} can be \texttt{label}(default),
+\texttt{pin} or \texttt{legend}.
+
+\demo[0.6]{text}
+
+\demo[0.6]{legend}
+
+\subsection{Sum}
+The value of \texttt{sum} indicats the sum of all data in the chart,
+it is 100 by default. It can be calculated automatically when
+\texttt{auto} is set.
+
+\demo{sum}
+
+\subsection{Color}
+The color can be specified by \texttt{color}, the default color wheel
+is shown in figure \ref{fig:color-wheel}.
+
+\demo{color}
+
+
+\begin{figure}
+  \centering
+  \input{demo/colorwheel}
+  \caption{Default color wheel}
+  \label{fig:color-wheel}
+\end{figure}
+
+
+\subsection{Style}
+\subsubsection{shadow}
+\demo[0.6]{shadow}
+
+\section{Examples}
+
+% \subsection{Population of the world}
+% \example{population}
+
+% \section{Acknowledgements}
+% Many people contributed to \texttt{pgf-pie} by reporting problems,
+% suggesting various improvements or submitting code. Here is a list of
+% these people:
