+Before beginning this tutorial,we would suggest having a working installation of
+LaTeX on your computer. You can do this by completing the tutorial titled 
+"Installing LaTeX".
+
+.. L4

+
+LaTeX began as TeX, a computer program originally created by
+Donald E. Knuth. Its was designed mainly to aid typesetting
+of text and mathematical formulae. 
+
+LaTeX is a document preparation system for high quality type 
+setting. It is based on the TeX typesetting language or certain
+extensions.
+
+LaTeX is pronounced Lah-tech or Lay-tec.
+TeX is pronounced Tech. TeX is also the first syllable in the Greek word for
+technology.
+LaTeX allows authors to typeset and print their content at the highest
+typographical quality, using predefined, professional layouts.
+
+.. L5
+
+
+.. R5
+
+Below are some of the reasons we prefer LaTeX
+(a) LaTeX offers excellent visual quality.
+(b) It handles typesetting and lets you focus on content.
+(c) Its makes writing complex math equation extremely simple.
+(d) It is also a standard used widely, especially by the scientific community. 
+
+We can define LaTex as a document based markup language. This sentence is
+deceptively simple, as it reveals a lot about LaTex. We now break this sentence
+up as follows
+Mark-up — a system of annotating text, adding extra information to
+specify structure and presentation of text
+Document based markup - you don’t have to worry about each
+element individually.
+This is essentially a fancy way of saying,LaTeX handles typesetting and lets 
+you focus on content.
+
+.. L6
+
+{{{ switch to stock photograph of/symbolizing advantages and disadvantages  }}}
+
+.. R6
+
+Some of the advantages of using LaTeX approach to typesetting are
+(1) Easy availability of professionally crafted layouts.
+(2) Typesetting of mathematical formulae is supported in a convenient
+environment.
+(3) Typesetting for most cases can be done with very little learning curve
+using easy to use/understand commands, that only specify the logical structure
+of the document.
+(4) Presence of lots of add-on packages.
+(5) It encourages creation of well structured texts.
+
+.. L7
+
+{{{ switch to stock photograph of/symbolizing advantages and disadvantages  }}}
+
+.. R7
+
+Some of the disadvantages of using LaTeX approach to typesetting is 
+(1) Designing a whole new layout is difficult.
+
+.. L8
+
+{{{ switch to Image saying/symbolizing work flow }}}

+
+LaTeX input files are simple ASCII text files that are processed by a TeX
+processing engine. 
+Next comes the question compiling LaTeX input files and viewing the output
+typeset document.
+The process is a little different from other markup languages like HTML.
+We compile ASCII text files into typeset files that are normally DVI,Postscript
+or PDF files.
+The latex command converts LaTeX input files into dvi files.
+We can view DVI files on Gnu/Linux using xdvi.
+Further  DVI files can be converted either to a post script file, using the
+dvips command or to a PDF file using the dvipdfm command.
+The command pdflatex is used to convert LaTeX input files directly to pdf files.
+The resultant PDF files can be viewed using standard tools on most platforms
+(Eg: evince on Gnu/Linux). PDF file are also widely supported.
+
+.. L9
+
+
+.. R9
+
+LaTeX, like most utilities in Linux is case sensitive. Commands begin with a
+backslash.LaTeX environments have a begin and end marker. Any content after
+\end{document} is ignored.
+
+Anything that follows a percentage sign (%) till the end of that line is a
+comment. Special characters like tilde or hash,etc have to be escaped by a
+backslash. If you have to insert a backslash into a LaTeX output file, you have
+to use the LaTeX command \textbackslash.
+
+Normally LaTeX automatically spaces the given input optimally. But, sometimes we
+have to insert manual line breaks. This is achieved using the \\ command.
+
+We can also start a new paragraph using an empty line.
+
+It must be noted that multiple spaces/empty lines are automatically compressed 
+to a single space/line.

+
+Now, we try to create a simple LaTeX document. Pause the tutorial and type the
+content shown on the screen in a text editor. Save the file as temp.tex
+
+.. L10
+
+{{{continue from paused state}}}
+latex temp.tex 
+
+.. R10
+
+Now we compile the commands in the LaTeX input file that is, temp.tex into a 
+typeset file.
+The first alternative is to compile LaTeX input file into a DVI file. We use 
+the latex command for this purpose.
+For compiling the LaTeX input file temp.tex into a DVI file, we use the
+following command
+latex temp.tex. 
+The output file would be temp.dvi.
+On Gnu/Linux use a program like xdvi to view the output file.
+
+.. L11
+
+pdflatex temp.tex
+
+.. R11
+
+The other alternative is to create PDF files from LaTeX input files.
+We use the pdflatex command for this purpose. 
+For compiling the LaTeX input file temp.tex into a PDF file, we use the
+following command
+pdflatex temp.tex
+The output file would be temp.pdf
+On Gnu/Linux use a program like evince to view the output file.

+
+This brings us to the end of this tutorial. In this tutorial, we have learnt
+
+.. 1. About LaTeX.
+.. #. why we prefer LaTeX.
+.. #. About the advantages and disadvantages of typesetting documents  
+..    using the LaTeX approach.
+.. #. A description, of a typical work flow; which uses LaTeX to typeset 
+..    documents.
+.. #. The ability to recognize and differentiate between LaTeX commands, LaTeX
+..    comments and special characters, spacing and actual document content.
+.. #. Created and compiled a very simple LaTeX document.

+{{{Show self assessment questions slide}}}
+
+.. R13
+
+Here are some self assessment questions for you to solve
+
+ 1. Convert the temp.dvi created during the course of this tutorial to temp_1.ps
+using the dvips command. Verify that the two files indeed look the same.
+
+ 2. Convert the temp.dvi created during the course of this tutorial to
+temp_1.pdf using the dvipdfm command. Verify that the two files indeed look the
+same.
+
+.. L14
+
+{{{Show self assessment questions slide}}}
+
+.. R14
+
+And the answers,
+
+1. We can use the following command to convert temp.dvi to temp_1.ps
+dvips -o temp_1.ps temp.dvi
+
+2. We can use the following command to convert temp.dvi to temp_1.pdf
+dvipdfm -o temp_1.pdf temp.dvi
