    <para>The following commands are understood:</para>

      <varlistentry>
        <term><command>list</command> [<replaceable>TARGET</replaceable>[@<replaceable>VERSION</replaceable>]]</term>

        <listitem><para>Show information about targets and their versions.</para>

        <para>When no <replaceable>TARGET</replaceable> is specified, this command lists all
        available targets. When a <replaceable>TARGET</replaceable> is specified without a
        <replaceable>VERSION</replaceable>, this command lists all known versions of the
        specified target. If a <replaceable>VERSION</replaceable> is specified, this command
        lists all known information about the specific version.</para>

        <para>See the example below for details of the output.</para>

      </varlistentry>

      <varlistentry>
        <term><command>update</command> [<replaceable>TARGET</replaceable>[@<replaceable>VERSION</replaceable>]…]</term>

        <listitem><para>Update the specified targets to the specified versions. If a target
        is specified without a version, then it will be updated to the latest version. If no targets are
        specified, then all available targets will be updated to the latest version.</para>

        <xi:include href="version-info.xml" xpointer="v257"/></listitem>

      </varlistentry>

      <varlistentry>
        <term><command>features</command> [<replaceable>FEATURE</replaceable>]</term>

        <listitem><para>When no <replaceable>FEATURE</replaceable> is specified, this command lists all
        optional features.
        When a <replaceable>FEATURE</replaceable> is specified, this command lists all known information
        about that feature.</para>

        See <citerefentry><refentrytitle>sysupdate.features</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
        These commands always operate on the host system.</para>

        <para>By default, these commands will only change the system's configuration by creating or deleting
        drop-in files; they will not immediately download the enabled features, or clean up after the
        disabled ones.
        Enabled features will be downloaded and installed the next time the target is updated, and disabled
        transfers will be cleaned up the next time the target is updated or vacuumed.
        Pass <option>--now</option> to immediately apply these changes.</para>
