Z:gnu-www-ja-fdl-howto-opt--b2f6e5-The old Emacs Manual license d/en

The old Emacs Manual license did not allow others who modify and redistribute the manual to add new invariant sections. But while formulating a more general version of the concept for the GNU FDL, I felt that it would be more morally consistent if those who modify a manual can write invariant sections, just as the first authors can. The FDL permits this.
