\section{Introduction}

\begin{frame}
  \frametitle{\LaTeX~- Introduction}
  \begin{itemize}
  \item Typesetting program
  \item Excellently Typeset Documents - specially Math
  \item Anything from one page articles to books. 
  \item Based on \TeX
  \item Pronounced ``Lah-tech'' or ``Lay-tech''
  \end{itemize}
\end{frame}

\begin{frame}
  \frametitle{This Course}
  \begin{itemize}
  \item Look at Sample document - \texttt{sample.pdf}
  \item The document will be produced by the end of the course. 
  \item First Hour - Basic Structure
  \item Second Hour - Text, Tables, Figures, References
  \item Third Hour - Math, Bibliography, Presentations
  \end{itemize}
\end{frame}

  \frametitle{The source \& compilation}
  Write the following code into the file \texttt{draft.tex}.
  \begin{lstlisting}
    \documentclass{article}
    \begin{document}
    SciPy is open-source software for mathematics, 
    science, and engineering.   
    \end{document}
  \end{lstlisting}
  To compile the document, do the following in your terminal: 
  \begin{lstlisting}[language=bash]
    $ pdflatex draft.tex
  \end{lstlisting}
  This produces the output file \texttt{draft.pdf} %%$
  Note: \texttt{latex} command is often used to get \texttt{dvi}
  output. Throughout this course, we shall use \texttt{pdflatex} to
  compile our documents to \texttt{pdf} output.
\end{frame}  

\section{Structure of the Document}

\begin{frame}[fragile]
  \frametitle{\lstinline+documentclass+}
  \begin{itemize}
  \item \LaTeX~typesets based on \lstinline{documentclass}
  \item Defines structure and formatting of a document
  \item \LaTeX~is a document based mark-up
  \item Mark-up --- a system of annotating text, adding extra
    information to specify structure and presentation of text
  \item Document based markup $\rightarrow$ you don't have to worry
    about each element individually 
  \item Allows you to focus on content, rather than appearance.
  \end{itemize}

  \frametitle{Bibliography}
  \begin{itemize}
  \item \lstinline+thebibliography+ environment provides a clean and
    simple way to add a bibliography to \LaTeX documents. 
  \item \lstinline+\begin{thebibliography}+ takes as argument the
    maximum with of the label that references will have. 
  \item Each item of the Bibliography is similar to an item in a
    list. 
  \item \lstinline+\bibitem[label]{name}+ followed by the actual
    reference info. 
  \item label replaces auto enumeration numbers 
  \item \lstinline+\cite{name}+ is used to \lstinline+cite+ the
    \lstinline+bibitem+ 
  \item You will need to compile twice. 
  \end{itemize}

\section{Presentations - Beamer}
\begin{frame}[fragile]
  \frametitle{Beamer}
  \begin{itemize}
  \item Use beamer since your report's \LaTeX~ would be re-usable.
  \item It is recommended to start with on of the beamer templates.
  \item Let's look at speaker introduction template.
  \item \lstinline+\documentclass{beamer}+ tells \LaTeX~ to start a
    beamer presentation. 
  \item A beamer document is very similar to any other \LaTeX~
    document except that content is divided into slides. 
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Beamer \ldots}
  \begin{itemize}
  \item \lstinline+\usetheme+ command is used to specify the theme of the
    presentation. 
  \item \lstinline+\usecolortheme+ command is used to specify the color
    theme. 
  \item The content of a slide is enclosed within
    \lstinline+\begin{frame}{Title}{Subtitle}+ and
    \lstinline+\end{frame}+ 
  \item If the slide contains \lstinline+verbatim+
    \lstinline+lstlisting+ environments, the \lstinline+\begin{frame}+
    should be passed an additional argument \lstinline+[fragile]+
  \item Overlays can be achieved using the \lstinline+\pause+
    command. 
  \item To achieve more with beamer, it is highly recommended that you
    look at the \texttt{beameruserguide}
