 There's no need to worry about whether an individual file has changed
 in a given year - it's sufficient that Emacs as a whole has changed.

 Therefore the years are updated en-masse near the start of each year,
 so basically there is no need for most people to do any updating of them.
 
-The current (in 2011) version of "Information for Maintainers of GNU
