    <title>Audience and Purpose</title>

    <para>This guide describes concepts and procedures for accessing information stored in the AFS filespace. It is intended for AFS
    users who are familiar with UNIX but not necessarily AFS.</para>

    <para>The first chapter describes basic AFS concepts and guidelines for using it, and summarizes some of the differences between
    the UNIX file system and AFS. The remaining chapters explain how to perform basic AFS functions, including logging in, changing
    a password, listing information, protecting files, creating groups, and troubleshooting. Concepts important to a specific task
    or group of related tasks are presented in context, just prior to the procedures. Many examples are provided.</para>

    <para>Instructions generally include only the commands and command options necessary for a specific task. For a complete list of
    AFS commands and description of all options available on every command, see the <emphasis>OpenAFS Administration
    Reference</emphasis>.</para>
