    <para>
      <command>lxc-cgroup</command> gets or sets the value of a
      <replaceable>state-object</replaceable> (e.g., 'cpuset.cpus')
      in the container's cgroup for the corresponding subsystem (e.g.,
      'cpuset'). If no <optional>value</optional> is specified, the
      current value of the <replaceable>state-object</replaceable> is
      displayed; otherwise it is set.
    </para>

    <para>
      Note that <command>lxc-cgroup</command> does not check that the
      <replaceable>state-object</replaceable> is valid for the running
      kernel, or that the corresponding subsystem is contained in any
      mounted cgroup hierarchy.
