-Do not abbreviate the year list using a range; for instance, do not
-write @samp{1996--1998}; instead, write @samp{1996, 1997, 1998}.
+You can use a range (@samp{2008-2010}) instead of listing individual
+years (@samp{2008, 2009, 2010}) if and only if: 1)@tie{}every year in
+the range, inclusive, really is a ``copyrightable'' year that would be
+listed individually; @emph{and} 2)@tie{}you make an explicit statement
+in a @file{README} file about this usage.
