+        The DATE in the .TH macro is in `yyyy-mm-dd' format, and should
+        reflect the most recent *non-trivial* update to the *content* of
+        the manpage; formatting changes don't count, nor does expanding
+        the `SEE ALSO' list.  Ask "Would the familiar user wish to
+        re-read this page to learn of this change?"
