Emacs cleanup

Because I'm always needing this between tasks...
 
;; kill buffers visiting /scratch or /tmp files
(defun cleanup ()
  (interactive)
  (let* (
         (n)
         (list)
         (file)
         )
    (setq list (buffer-list))
    (setq n 0)
    (save-excursion
      (dolist (elt list)
        (setq file (buffer-file-name (get-buffer elt)))
        (if (and
             file
             (or
              (string-match "^/scratch/" file)
              (string-match "^/tmp/" file)
              )
             )
            (progn
              (if (kill-buffer elt)
                  (setq n (+ n 1))
                )
              )
          )
        )
      (message "Delete %d buffer%s." n (if (= n 1) "" "s"))
      )
    )
  )
