+Refill minor mode provides support for keeping paragraphs filled as you
+type or modify them in other ways. It provides an effect similar to
+typical word processor behaviour. This works by running a
+paragraph-filling command at suitable times.
+
+When you are typing text, only characters which normally trigger auto
+filling, like the space character, will trigger refilling. This is to
+avoid making it too slow. Apart from self-inserting characters, other
+commands which modify the text cause refilling.
+
+The current implementation is preliminary and probably not robust. We
+expect to improve on it.
