    <title>Introduction to Git</title>

    <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>.</para>
