    <title>Installing Games on Ubuntu</title>

    <para>The default installation package of Ubuntu 7.10 comes with 17 Ubuntu
    games, including Aisleriot, Solitaire, Gnometris and Mines. In addition,
    you can install many games from other repositories.</para>

      <title>Instructor Notes:</title>

      <para>Understanding repositories is important because games are located
      in various repositories. You may need to recap on Lesson 1. Pre-install
      the two games covered in the lesson on every computer prior to starting
      the day or session otherwise this will take up too much time during
      class.</para>

      <para>Enabling a repository is a one-time task. You do not have to
