+This directory contains the default EM_CODE(3L) interface. That is :
+ 1) message-instruction are ignored.
+ 2) pseudo-instruction are almost machine independent, so they are
+ implemented completely. *)
+ 3) storage-instruction are almost machine independent, so they are
+ implemented completely. *)
+ 4) The other EM instructions generate a "not implemented"
+ message.
+
+The file "pseudovars.c" contains two global variables. 'locals_created' tells if
+the prolog is exected or not. 'Busy' tells if the code expander is running
+or not.
