;;; Sample Setup Code:

;; and able to figure out how to use it.  It isn't really part of
;; ps-print, but I'll leave it here in hopes it might be useful:

;; WARNING!!! The following code is *sample* code only.
;; Don't use it unless you understand what it does!

;; The key `f22' should probably be replaced by `print'.  --Stef

;; A hook to bind to `rmail-mode-hook' to locally bind prsc and set the
;; `ps-left-headers' specially for mail messages.
