+the first character of words are capitalized).  It automatically accounts for
+diacritical marks (like umlauts), national symbols (like @samp{ae}),
+punctuation, and font changing commands that alter the appearance or size of
+the text.  It allows a list of predesignated words to be protected as
+lower-cased, and also allows for titling exceptions of various sorts.")
