  \frametitle{Why should I use it?}

  For a single user:
  \begin{itemize}
    \item Revert files to a previous state.
    \item Revert the entire project back to a previous state.
    \item Review changes made over time.
    \item Backup.
    \item \ldots
  \end{itemize}
  \bigskip
  \pause

  For multiple users:
  \begin{itemize}
    \item A reliable way to share files between people/computers.
    \item Allow multiple people working on the same project at the same time.
    \item Conflict resolution.
    \item See who made what changes at when.
    \item \ldots
  \end{itemize}
\end{frame}

\begin{frame}
  \frametitle{Why should I not use it?}

  A list of common excuses:
  \begin{itemize}
    \item It is too much work.
    \item I have my own system.
    \item I am the only one working on this project.
    \item This code will not be used by anyone else.
    \item The bugs can be tracked forever.
    \item \ldots
    \pause
    \item I'm too busy rewriting the code I accidentally deleted.
  \end{itemize}
