+.. function:: capwords(s[, sep])
+
+   Split the argument into words using :meth:`str.split`, capitalize each word
+   using :meth:`str.capitalize`, and join the capitalized words using
+   :meth:`str.join`.  If the optional second argument *sep* is absent
+   or ``None``, runs of whitespace characters are replaced by a single space
+   and leading and trailing whitespace are removed, otherwise *sep* is used to
+   split and join the words.
