+<p>Each def record has a special entry called "NAME."  This is the
+name of the def ("ADD32rr" above).  In the general case def names can
+be formed from various kinds of string processing expressions and NAME
+resolves to the final value obtained after resolving all of those
+expressions.  The user may refer to NAME anywhere she desires to use
+the ultimate name of the def.  NAME should not be defined anywhere
+else in user code to avoid conflict problems.</p>
