+
+We use some conventions in this manual.
+
+@itemize @bullet
+
+@item
+For some procedures, notably type predicates, we use "iff" to mean
+"if and only if".  The construct is usually something like: "Return
+VAL iff CONDITION", where VAL is usually "#t" or "non-#f".  This
+typically means that VAL is returned if CONDITION holds, and that #f is
+returned otherwise.
+
+@c Add other conventions here.
