;; package-get -
;; Retrieve a package and any other required packages from an archive
;;
+;;
+;; Note (JV): Most of this no longer applies!
+;;
;; The idea:
;; A new XEmacs lisp-only release is generated with the following steps:
;; 1. The maintainer runs some yet to be written program that
;; vm - a mail reader
;; [] Always install
;; [] Needs updating
-;; [] Required by other [packages]
+;; [] Required by other [packages]
;;
;; Where `[]' indicates a toggle box
;;
;; - "Required by other" means some other packages are going to force
;; this to be installed. Clicking on [packages] gives a list
;; of packages that require this.
-;;
+;;
;; The `package-get-base' should be installed in a file in
;; `data-directory'. The `package-get-here' should be installed in
;; site-lisp. Both are then read at run time.
