\section{About this manual}
This manual is meant as a programmers' reference to the GSNAKE API. It covers all the classes and explains the use, arguments and return values of each of the methods. All protected methods and members are not covered in the manual. 

Throughout the manual, all class names are in CAPITAL and {\tt typewriter} font, when the item being referred to is the object as an entity. When it is the member or data structure of the object that is being referred, the name will be in {\tt typewriter} font.

At the end of the reference for each class, some example programs are provided. These are workable program segments for users to familiarize with the workings and application of the API. 

The manual is organised as follows: 
\begin{itemize}

	\item Chapter 1 explains the design of the API. 
	\item Chapter 2 contains the references to each class and their methods.
	\item Chapter 3 covers the various utilities provided with the API.   
\end{itemize}

\section{How to Avoid Reading this Manual}

The examples after the reference of each class, as well as the utilities programs, provide a rather rich collection of applications one can perform using the GSNAKE API. One may start by looking at these programs, and treat this manual as what it is : a {\em reference} manual.
