    <title>Audience and Purpose</title>

    <para>This reference manual details the syntax of each OpenAFS command and
    is intended for the experienced AFS administrator, programmer, or user.</para>

    <para>In general, this document does not explain when to use a command or its place in the sequence of commands that make up a
    complete procedure. For that type of information, refer to the <emphasis>OpenAFS Administration Guide</emphasis>.</para>

    <title>Organization</title>

    <para>This document presents OpenAFS files and commands in separate sections, with the files or commands in alphabetical
    order.</para>

    <para>The following sections of each reference page provide the indicated type of information:</para>

    <itemizedlist>
      <listitem>
        <para><emphasis role="bold">Purpose</emphasis> briefly describes the command's function.</para>

      <listitem>
        <para><emphasis role="bold">Synopsis</emphasis> displays the complete syntax statement for a command, which specifies the
        required order for all options, using the same notation as the OpenAFS online help. If abbreviating the command name a nd option
        names is acceptable, as it is for most commands, a second statement specifies the shortest acceptable abbreviation of each
        name. If the command has an alias, it also appears in this section.</para>

      <listitem>
        <para><emphasis role="bold">Examples</emphasis> provides one or more sample commands and resulting output.</para>

    <para><emphasis>OpenAFS Administration Guide</emphasis></para>

    <para>This guide describes the concepts and procedures that a system administrator must know to manage an AFS cell. It assumes
    familiarity with UNIX, but requires no previous knowledge of AFS.</para>

    <para>The first chapters of the <emphasis>OpenAFS Administration Guide</emphasis> present basic concepts and guidelines.
    Understanding them is crucial to successful administration of an AFS cell. The remaining chapters in the guide provide
    step-by-step instructions for specific administrative tasks, along with discussions of the concepts important to that particular
    task.</para>

    <para><emphasis>OpenAFS Quick Beginnings</emphasis></para>

    experienced UNIX<superscript><superscript>(R)</superscript></superscript> system administrator.</para>

    <para>For predictable performance, machines must be installed and configured in accordance with the instructions in this
    guide.</para>

    <para><emphasis>OpenAFS Release Notes</emphasis></para>

    <para>This document provides information specific to each release of OpenAFS, such as a list of new features and commands, a list of
    requirements and limitations, and instructions for upgrading server and client machines.</para>

    <para><emphasis>OpenAFS User Guide</emphasis></para>

    <para>This guide presents the basic concepts and procedures necessary for using AFS effectively. It assumes that the reader has
