The Free Software Foundation may publish new, revised versions of the GNU Free Documenta 

tion 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 http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document speci 

fies that a particular numbered version of this License "or any later version" 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.
