Thanks a lot for the suggestion, it works. I did not use
`org-forward-element' as it does not iterate on sub-items. I simply do
a `forward-line' to go done.

Here is the code, if it's helpful to others.

#!/usr/local/bin/emacs --script

(require 'org)

(with-temp-buffer
  (progn
    ; read the file in the temporary buffer
    ; do not add a \n at the end
    (condition-case nil
    (let ((line (read-from-minibuffer "")))
      (insert line)
      (while (setq line (read-from-minibuffer ""))
        (insert "\n")
        (insert line)))
    (error nil))
    ; do what you want here
    (goto-char (point-min))
    (while (< (point) (point-max))
      (org-fill-paragraph)
      (forward-line))
    (princ (buffer-string))))

Thanks again,
