+The @reqlink{mark-as-read} call is a reasonably good way to mark a
+single text as read (but one could argue that it should take a single
+@type{Text-No} and an @type{ARRAY Conf-No} as arguments), but there is
+no easy way to undo such an operation.  You can use
+@reqlink{set-last-read} followed by a number of @req{mark-as-read}
+calls to get the desired effect, but it would be nice to have a
+@samp{mark-as-unread} call.
