+  analyzed   - Display analyzed AST
+  optimized  - Show optimized AST
+  js         - Generate JavaScript code
 
-  parsed     a message that the program was matched ok by the grammar
-  analyzed   the statically analyzed representation
-  optimized  the optimized semantically analyzed representation
-  js         the translation to JavaScript
