;;FILE: init.lisp
;;LANGUAGE: Common-Lisp
;;SYSTEM: Common-Lisp
;;USER-INTERFACE: NONE
;;DESCRIPTION
;;
;; Initialization for common-lisp packages.
;;
;; This files remove some specificities from the lisp environment
;; (to make it more Common-Lisp),
;; loads the package COM.INFORMATIMAGO.COMMON-LISP.PACKAGE,
;; and add logical pathname translations to help find then other packages.
;;
;; Since we're generating an image, it should be useful only
;; at compilation-time, so any path present here should not be needed
;; at run-time. (But we don't clear them from the translations...).
