;; ;; Make emacs open all files in last emacs session (taken from ergoemacs).

;; ;; This functionality is provided by desktop-save-mode
;; ;; (“feature” name: “desktop”).
;; ;;
;; ;; The mode is not on by default in emacs 23.1, and has a lot options.
;; ;; The following is init settings for the mode for ErgoEmacs.
;; ;; Goal: have emacs always auto open the set of opened files in last session,
;; ;; even if emacs crashed in last session or the OS crashed in last session.
;; ;; Also, don't bother users by asking questions like “do you want to save
;; ;; desktop?” or “do you want to override last session file?”, because these are
;; ;; annoying and terms like “session” or “desktop” are confusing to most users
;; ;; because it can have many meanings.
;; ;;
;; ;; Some tech detail: set the desktop session file 〔.emacs.desktop〕
;; ;; at the variable “user-emacs-directory” (default value is “~/.emacs.d/”).
;; ;; This file is our desktop file. It will be auto created and or over-written.
;; ;; If a emacs expert has other desktop session files elsewhere, he can still use
;; ;; or manage those.
