+\begin{abstract}
+  \texttt{pgf-pie} is a LaTeX package for drawing pie chart (and
+  variant charts). 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{Usage}
+
+\subsection{First Pie}
+\lstinline|\pie| is the only coomand that provided by
+\texttt{pgf-pie}. The argument is a list of number and text
+combination in the formate of \texttt{number/text}, i.e. \texttt{10/A,
+  20/B, 30/C, 40/D}. The result is shown in figure \ref{fig:first-pie}.
+\begin{figure}
+  \centering
+  \demo[0.6]{first-pie}
+  \caption{The first pie.}
+  \label{fig:first-pie}
+\end{figure}
+
+\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{Color}
+The color can be specified by \texttt{color}, the default color wheel
+is shown in figure \ref{fig:color-wheel}.
+\begin{figure}
+  \centering
+  \input{demo/colorwheel}
+  \caption{Default color wheel}
+  \label{fig:color-wheel}
+\end{figure}
+
+\demo{color}
+
+\subsection{Explode}
+\demo{explode}
+
+\subsection{Angle of slices}
+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. Then the angle of slices are determined by
+number value and \texttt{sum}.
+
+\demo{sum}
+
+\subsection{Text}
+
+\subsubsection{Number}
+Two parameters can be used to decorate number: \texttt{before number}
+and \texttt{after number}. Both are empty by default, but if
+\texttt{sum=100}, \texttt{after number} will be set to \%
+automatically if user doesn't set it.
+
+\demo[0.6]{before-after-number}
+
+\paragraph{Scale font}
+The size of font in size pie can be scaled according to how big the
+part is automatically.
+
+\demo[0.6]{scalefont}
+
+\subsubsection{Label text}
+The value of \texttt{text} can be \texttt{label}(default),
+\texttt{pin}, \texttt{inside} or \texttt{legend}.
+
+\demo[0.6]{text}
+
+\demo[0.5]{text-inside}
+
+\demo[0.6]{legend}
+
+\subsection{More about style}
+\subsubsection{shadow}
+\demo[0.6]{shadow}
+
+\section{Variant Charts}
+\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{Square}
+
+\demo[0.6]{square}
+
+Note: \texttt{explode} has no affects in sqaure chart.
+
+\subsection{Clouds}
+
+\demo[0.6]{cloud}
+
+\section{Examples}
+
+% \subsection{Population of the world}
+% \example{population}
+
