+Before beginning this tutorial,we would suggest having a working installation of
+LaTeX and suggest you to complete the tutorial titled "Introduction to LaTeX".
+
+.. L4
+
+{{{ Basic Structure of a LaTeX document }}}
+\documentclass{article}
+\begin{document}
+SAMPLE TEXT
+\end{document}
+
+.. R4
+
+the text "SAMPLE TEXT" is illustrative and can be replaced replaced by a 
+single alpha-numeric character, for example. When done so, the resulting 
+document could be described as the shortest possible LaTeX input document, that
+creates an output file. It consists of 3 LaTeX commands and one line/character
+of text.
+This is processed by a TeX processor that generates an output file. Now, we 
+begin to look into each line in the example in more detail.
+The first line reads
+
+.. L5
+
+\documentclass{article}
+
+.. R5
+
+which more generally can be written as
+
+.. L6
+
+\documentclass [parameters] {DocumentClass}
+
+.. R6
+
+Where \documentclass is a LaTeX command.
+Parameters specify if you want to use a non default font size, for example.
+More specifically the parameters can be used to alter things like font size of 
+the document, paper size, two sided or single sided printing, etc.
+
+.. L7
+
+\documentclass[12pt,a4paper,draft]{report} 
+
+.. R7
+
+This command instructs LaTeX to 
+Create a new document of class report. The available classes are article, proc,
+report, book, slides, letter.
+12 pt: sets the font size of main font. Other are relatively adjusted. 10pt is
+the default. 
+a4paper: specifies the paper size
+draft:  marks hyphenation and justification problems in typesetting
+with a square in the margin
+
+.. L8
+
+\usepackage[options]{...}
+
+.. R8
+
+This statement can be used optionally and is used to include packages, which are
+used to extend the LaTeX's capabilities. There are a number of packages that are
+included by default with LaTeX2 base distribution. You can use the texdoc
+command for accessing package documentation.
+
+.. L9
+::
+
+\documentclass{article}
+\title{My First LaTeX Document}
+\author{Harish}
+\date
+\begin{document}
+Hello world!
+\end{document}
+
+.. R9
+
+We add the LaTeX commands, that specify the title and the author of the
+document. When we compile the document shown to an output file and view it we
+notice that output is, as seen no different from not adding the fields of title
+and author. We need to add another command to actually show the title author 
+and date in the output document. We add the command in the following example.
+
+.. L10
+
+\documentclass{article}
+\title{My First LaTeX Document}
+\author{Harish}
+\begin{document}
+\maketitle
+Hello world!
+\end{document}
+
+.. R10
+
+The command \maketitle adds title, authors name and date to the output file.
+Of these only the date is optional. If date command is specified, then the given
+date is used else today's date is used. 
+
+.. L11
+
+\documentclass{article}
+\title{My First LaTeX Document}
+\author{Harish}
+\begin{document}
+\maketitle
+Hello world!
+\begin{abstract}
+An Example Abstract
+\end{abstract}
+\end{document}
+
+.. R11
+
+The abstract command is used to insert abstract of a document, into the output
+file.Place it in the location, where you want your abstract to present in
+the document. It is available for the document classes article and report, but
+not book
+
+.. L12
+
+\documentclass{article}
+\title{My First LaTeX Document}
+\author{Harish}
+\begin{document}
+\maketitle
+Hello world!
+\begin{abstract}
+An Example Abstract
+\end{abstract}
+\section{Numbered Section 1}
+Section1 Text
+\section{Numbered Section 2}
+Section2 Text
+\section*{Unnumbered Section 1}
+Section3 Text
+\section*{Unnumbered Section 2}
+Section4 Text
+\end{document}
+
+
+.. R12
+
+Titles chapters and sections are used to help the user find his or her way
+through your work. The following commands are available in the article class:
+section, subsection, subsubsection,  paragraph and sub paragraph. The default
+behavior is to use numbered sections. We can use un-numbered sections appending
+* to section command. If you want to split your document without influencing the
+section or chapter numbering use the part command.
+
+.. L13
+
+\documentclass{book}
+\title{My first Book}
+\author{Harish}
+\date{31-February-2012}
+\begin{document}
+\maketitle
+\chapter{My First Chapter}
+Main
+\section{Section1}
+Section 1 Text
+\subsubsection{My First Subsection}
+Numbered-Section 1's Subsection Text
+\section{Section2}
+Numbered-Section 2 Text
+\section*{Section3}
+First un-numbered Section Text
+\section*{Section4}
+Second un-numbered Section Text
+\chapter{So We say goodbye}
+Thank you for reading dear reader
+\end{document}
+
+.. R13
+
+Longer documents can use report or book class. We can add a new chapter using
+the chapter command, provided by the report or book class. After compiling the
+file shown in the slide we notice that subsections are not numbered. 
+
+.. L14
+
+\setcounter{secnumdepth}{3}
+
+.. R14
+We can change this behavior with the command setcounter , calling it as shown
+in the slide. 
+
+.. L15
+
+\appendix
+
+.. R15
+
+Appendix can be added to the document using \appendix command. any content after
+\appendix will be added to the appendix. In the report or book class, we have to
+use \chapter to indicate that the chapters are to be numbered as appendices.
+
+similarly for the article class we have to use the section command to indicate
+that sections are to be numbered as appendices.
+
+.. L16
+
+
+.. R16
+
+Lets add a Table of content to the document. The LaTeX command to add a TOC to a
+document is using \tableofcontents command. It is used at the point at which the
+table of content is to be placed. You then have to compile the input file twice
+to produce a text. 
+Any numbered section/chapter appear automatically in the table of content.
+
+.. L17
+
+
+.. R17
+
+Un-numbered sections are added to TOC using \addcontentsline command.
+For example we use the command
+\addcontentsline{toc}{section}{Intro}
+where intro is the text that you want to appear in the Table of contents.

+
+This brings us to the end of this tutorial. In this tutorial, we have,
+
+.. 1. Gained an understanding of the basic structure of a LaTeX document, its 
+..    various document classes and loading packages that add new features to 
+..    the LaTeX system.
+.. #. Created a LaTeX document with a title and an abstract.
+.. #. Created both numbered and non-numbered sections and subsections in a 
+..    LaTeX document.
+.. #. Created an appendix in a LaTeX document.
+.. #. Created a table of content in a LaTeX document.
+
+.. L19
+
+{{{Show self assessment questions slide}}}
+
+.. R19
+
+Here are some self assessment questions for you to solve
+
+ 1. Is the LaTeX code given below a valid input file (File compiles successfully
+and produces the intended result, that is to produce a book with two chapters 
+and an appendix.
+\begin{verbatim}
+\documentclass{book}
+\title{My first Book}
+\author{Harish}
+\date{31-February-2012}
+\begin{document}
+\maketitle
+\chapter{My First Chapter}
+Main
+\chapter{So We say goodbye}
+Thank you for reading dear reader
+\appendix
+\section{First Appendix}
+\end{document}
+\end{verbatim}
+
+ 2. Does making the subsections placed at any arbitrary level, get numbered by
+default using the appropriate setcounter command  with secnumdepth parameter
+make the subsections appear automatically in the table of content ??
+
+.. L20
+
+{{{Show self assessment questions slide}}}
+
+.. R20
+
+And the answers,
+
+1. Although the given file looks syntactically valid, the output file is not what
+we expected. This is mainly because we are trying to use the section command to
+create sections in the appendix, for a document whose type is given as a book.
+
+2. No The \tableofcontents command normally shows only numbered section
+headings, and only down to the level defined by the tocdepth counter.
