<title>Description</title>
  <para>
    In order to simplify saving the state of MDI and its children, the
    GnomeMDI interface provides a function that saves its layout and
    the state of its children (provided by each child through get_config_string
    virtual function defined in <type>GnomeMDIChild</type> subclasses) and a
    function that restores a previously saved state, recreating the children
    from their configuration strings using a function provided by the programmer.
  </para>
