    <para>
      <application>Git</application> is a free and open source, distributed
      version control system designed to handle everything from small to very
      large projects with speed and efficiency. Every
      <application>Git</application> clone is a full-fledged repository with
      complete history and full revision tracking capabilities, not dependent on
      network access or a central server. Branching and merging are fast and easy
      to do. <application>Git</application> is used for version control of files,
      much like tools such as <application>Mercurial</application>,
      <application>Bazaar</application>, <xref linkend="subversion"/>,
      <xref linkend="cvs"/>, <application>Perforce</application>, and
      <application>Team Foundation Server</application>.

      <filename class="directory">/usr/share/man</filename> before
      it starts to decompress the docs. The <option>--no-same-owner</option>
      option stops tar from preserving the user and group details of the
      files. This is useful as that user or group may not exist on your
      system; this could (potentially) be a security risk.
    </para>

    <para>
      <command>mv /usr/share/doc/git-&git-version; ...</command>: These
      commands move some of the files into subfolders to make it easier to sort
      through the docs and find what you're looking for.
    </para>

    <para>
      <command>find ... chmod ...</command>: These commands correct the 
      permissions in the shipped documentation tar file.
