To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and

If you have Invariant Sections, Front-Cover Texts and Back-Cover

LIST.
If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.

recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License, to
