    <title>DESCRIPTION</title>

    <para>Long drawn-out discussion of <command>&manpackage;</command>.
      It's a good idea to break this up into subsections, like these:</para>

    <refsect2>
      <title>A Sample Subsection</title>
      <para></para>
    </refsect2>
    <refsect2>
      <title>Yet Another Sample Subsection</title>

      <para>References to the
        <citerefentry>
         <refentrytitle>foo</refentrytitle><manvolnum>SECTION</manvolnum>
        </citerefentry> (or other) manual page should use the
        <markup>&lt;citerefentry&gt;</markup> element as here.
      </para>

      <para>Each paragraph within a section is contained within a
        <markup>&lt;para&gt;</markup> tag.</para>
    </refsect2>
  </refsect1>
  <refsect1>
    <title>OPTIONS</title>

    <para>Some people make this separate from the description.</para>

    <variablelist>
      <varlistentry>
        <term><option>this</option>|<option>that</option></term>
        <listitem>
          <para>The user MUST specify either <option>this</option> or
            <option>that</option> to run the program. The { and } braces
            mean one of the enclosed is required. The bar (|) separates
            exclusive options (i.e. you cannot have both at once.)</para>
        </listitem>
      </varlistentry>
      <varlistentry>
        <term><option>-o</option></term>
        <listitem>
          <para>Pass the user-supplied <replaceable>option</replaceable> to
            <command>foo</command> to change its behaviour. The fact that
            <replaceable>option</replaceable> is underlined or in italics
            means that the user replaces it with a valid value for this
            option. The [ and ] brackets mean it isn't required.</para>
