- * fe_init.cc - Initialize the FE
- *
- * The FE initialization is carried out in two stages, with the BE
- * initialization protocol sandwiched between the two stages.
- *
- * The first stage is responsible for creating the scopes stack.
- * The second stage is run after the BE initialization has created
- * and returned an instance of AST_Generator (or a subclass). This
- * instance is used to create the root node for the AST, and to
- * populate it with AST_PredefinedType nodes which represent the
- * predefined IDL types. This AST root is then pushed on the scopes
- * stack as the outermost scope.
