 // This header file defines the "virtual machine" used by machine-generated
 // code.  It is "dangerous" in that it #defines macros for all the gridfns,
-// which will likely produce syntax errors if they are used outside their
-// intentended environment.
+// which will break lots of other code.  Thus this file should only be
+// #included just before #including machine-generated code, and this should
+// be as close as possible to the end of the source file (to minimize the
+// amount of other code affected by this file).
