\frametitle{Objectives}
\label{sec-2}

At the end of this tutorial, you will be able to,
\begin{itemize}
  \item Understand what is Version Control
  \item Identify the need for using Version Control
  \item Install Mercurial
\end{itemize}
\end{frame}

% Introduction to course-need of version control, history, options available.
\section{Introduction}

\begin{frame}[fragile]
  \begin{block}{What is Version Control?}
    
    A way to track changes made to files over time, by keeping copies
    of files as we change them.
    
  \end{block}
\end{frame}

%% Home made version control system?

  \end{center}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Home-brewed contd.}
  \begin{itemize}
  \item Listing the files in the folder:
  \end{itemize}  
  \begin{lstlisting} 
	$ ls
	a.out  id1.txt  id2.txt string.txt
	identifier.cpp  id.txt  pda1.cpp
	pda2.cpp  pda.cpp  pda.txt  
  \end{lstlisting} %%$
   %% listing out the crazy names
\end{frame}

\begin{frame}[fragile]
  \frametitle{Problems}  
  \begin{block}{}    
  \begin{itemize}
  \item Name and changes made are not related or linked. 
  \item Can't track sequence of changes made to a file. 
  \item Does not scale. 
  \end{itemize}
  \end{block}
\end{frame}

\begin{frame}[fragile]
  \frametitle{The need for Version Control}
  \begin{itemize}
  \item Tracking the history and evolution of a project
  \item To collaborate effectively on a project
  \item To efficiently track down bugs and pin-point the changes that
    caused it 
  \item Useful for an individual and a group of people
  \end{itemize}
\end{frame}

%% Introduction to how logs are managed in VCS.
%% A analogy in logs and day-to-day life?
\begin{frame}[fragile]
  \frametitle{How does it work? --- Analogy}
  It is similar to playing an Video game.
  \begin{itemize}
  \item We play games in stages
  \item Once we finish a stage -- \alert{we SAVE}
  \item We continue playing
  \item But, if necessary, we could choose from one of the saved
    states and start from there
  %%\item We could alter the course of the game
  \end{itemize}

  \frametitle{Mercurial or \typ{hg}}
  \centering
  \includegraphics[height=.70in,interpolate=true]{mercurial_logo}
  \begin{itemize}
  \item Easy to learn and use
  \item Lightweight
  \item Scales excellently
  \item Written in Python
  \end{itemize}
\end{frame}


\begin{frame}
  \frametitle{Installation}
  \begin{itemize}
  \item \$ sudo apt-get install mercurial
  \item \$ hg
  \item \$ hg version
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Summary...}
  In this tutorial, we have learnt about,
  \begin{itemize}
  \item What is Version Control
  \item The need for using Version Control
  \item Installing Mercurial or hg
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Evaluation}
  \begin{enumerate}
  \item Is Mercurial a Centralized VCS or Distributed VCS?
  \item How can you retrive the version of Mercurial installed?
  \end{enumerate}
\end{frame}

\begin{frame}
  \frametitle{Solutions}
  \begin{enumerate}
  \item Mercurial is a Distributed Version Control system.
  \item hg version 
  \end{enumerate}
