;;; Commentary:
;; Emacs 24.4+ configuration file with many packages already enabled and a more
;; pleasant set of defaults.
;;
;; Operating systems: supposed to work both for Windows and for Linux.
;;
;; Minimal .emacs configuration file:
;;
;; (add-to-list 'load-path "/path/to/emacs-leuven/")
;; (require 'emacs-leuven)
;;
;; To get more debug info about the packages getting loaded, add the following
;; line before requiring Emacs-Leuven.
;;
;; ;; Show messages describing progress of loading Emacs-Leuven.
;; (setq leuven-verbose-loading t)
;;
;; To avoid being questioned about packages to add to your local Emacs
;; installation (though, I think you should install them), add the following
;; line before requiring Emacs-Leuven.
;;
;; ;; Do not (try to) install extra Emacs packages.
;; (setq package-selected-packages nil)
;;
;; To install all the extra packages used hereunder, without being questioned,
;; add the following line before requiring Emacs-Leuven.
;;
;; ;; Install all extra Emacs packages without asking for confirmation.
;; (setq leuven-install-all-missing-elpa-packages t)
;;
;; For help on the Emacs Editor, see (info "(emacs)") <== `C-x C-e' here!

;; Time the loading of Emacs Leuven. Keep this on top of your .emacs.
