    <title>Future Revisions of this License</title>

    <para>The Free Software Foundation may publish new, revised
    versions of the GNU Free Documentation License from time to time.
    Such new versions will be similar in spirit to the present
    version, but may differ in detail to address new problems or
    concerns.  See <ulink url="http://www.gnu.org/copyleft/" />.</para>

    <para>Each version of the License is given a distinguishing
    version number.  If the Document specifies that a particular
    numbered version of this License <quote>or any later version</quote> applies
    to it, you have the option of following the terms and conditions
    either of that specified version or of any later version that has
    been published (not as a draft) by the Free Software Foundation.
    If the Document does not specify a version number of this License,
    you may choose any version ever published (not as a draft) by the
    Free Software Foundation.</para>
