-Even image files and sound files should contain copyright notices and
-license notices, if their format permits. Some formats do not have

-copying permissions in a @file{README} file in the same directory.
+All files, including images, sound, and plain text, should contain
+copyright and license notices, if their formats allow them. When the

+@file{README} file, preferably in the same directory, and be clear in
+@file{README} which files those notices apply to.
Change log files should have a copyright notice and license notice at
