Re: FIles to be fixed with copyright header (year number)

[Richard Stallman]

    The CVS log can tell you which years changes were made to a file.

    It wouldn't be too hard to make a function which retrieves the
    list of years automatically.

    But how do you determine whether a change is nontrivial?

You have to do that by hand.  Fortunately, you don't have to study
the diffs beyond the point where you see they are nontrivial.
