;;; Commentary:  

;; Strictly for debugging and development.  usage is:
;;           xemacs -no-site-file -no-init-file -load ess-debug.el -f S4    
;; (or similar!)

;;; Code:


;;; For Tony's environment
;(require 'tex-site)
;(require 'x-symbol-hooks)
;(x-symbol-initialize)


(defun ess-add-path (path &rest options)
  "Add PATH to `load-path' if it exists under `default-load-path'
directories and it does not exist in `load-path'.

You can use following PATH styles:
	load-path relative: \"PATH/\"
			(it is searched from `default-load-path')
	home directory relative: \"~/PATH/\" \"~USER/PATH/\"
	absolute path: \"/HOO/BAR/BAZ/\"

You can specify following OPTIONS:
	'all-paths	search from `load-path'
			instead of `default-load-path'
	'append		add PATH to the last of `load-path'.

For ESS, ONLY use load-path, since Emacs doesn't have
default-load-path."

  (let ((rest load-path)
	p)
    (if (and (catch 'tag
	       (while rest
