// = DESCRIPTION
-// Visitor generating code for marshaling the return type variable
+// Visitor generating the code that passes retval to the CDR operators. The
+// "OUTPUT" substate deals with the server side skeletons whereas the
+// "INPUT" substate deals with the client stubs. Also notice that the type
+// of parameter passed to the operator depends on the manner in which the
+// variable is declared i.e., in the skeleton, we may have _var types but
+// not in the stubs.
