    <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 @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>
