+@item message-make-forward-subject-function
+@vindex message-make-forward-subject-function
+A list of functions that are called to generate a subject header for
+forwarded messages. The subject generated by the previous function is
+passed into each successive function.
+
+The provided functions are:
+
+@table @code
+@item message-forward-subject-author-subject
+@findex message-forward-subject-author-subject
+Source of article (author or newsgroup), in brackets followed by the
+subject.
+
+@item message-forward-subject-fwd
+Subject of article with @samp{Fwd:} prepended to it.
+@end table
+
+@item message-wash-forwarded-subjects
+@vindex message-wash-forwarded-subjects
+If this variable is @code{t}, the subjects of forwarded messages have
+the evidence of previous forwards (such as @samp{Fwd:}, @samp{Re:},
+@samp{(fwd)}) removed before the new subject is
+constructed. The default value is @code{nil}.
