How to make a new mode based on c++-mode

I have created a parser which translates a file into C++ source code.
The initial file has a syntax very close to C++ with some additional

I would like to provide an emacs mode for editing those files. 

For the moment I have written this :


;;; -*-emacs-lisp-*-
;;; castfront.el --- ELisp package for making castfront related stuff

(provide 'castfront)

(defconst castfront-keywords
    '(0 font-lock-warning-face prepend))

(defun castfront-font-lock ()
  "Turn on font-lock for CastFront keywords."
  (if (functionp 'font-lock-add-keywords)
      (font-lock-add-keywords nil castfront-keywords)
    (let ((old (if (eq (car-safe font-lock-keywords) t)
                 (cdr font-lock-keywords)
      (setq font-lock-keywords (append old castfront-keywords)))))


I have then added the following line to my .emacs :

(defun my-castfront-font-lock-hook ()
    (if (or (eq major-mode 'c-mode) (eq major-mode 'c++-mode))
(add-hook 'font-lock-mode-hook 'my-castfront-font-lock-hook)

This work pretty good. The only thing to do is to open my parsed file
with c++-mode. However I want more. I want them to have their own mode,
a mode that will automatically load the c++-mode to handle c++-construct
a that will add my keywords as above. How can I make it ?

Thank for help
