;; Save the Desktop, i.e.,
;; - some global variables
;; - the list of buffers with associated files. For each buffer also
;; - the major mode
;; - the default directory
;; - the point
;; - the mark & mark-active
;; - buffer-read-only
;; - some local variables

;; To use this, use customize to turn on desktop-save-mode or add the
;; following line somewhere in your .emacs file:
;;
;; (desktop-save-mode 1)
;;
;; For further usage information, look at the section
;; "Saving Emacs Sessions" in the GNU Emacs Manual.
;; When the desktop module is loaded, the function `desktop-kill' is
;; added to the `kill-emacs-hook'. This function is responsible for
;; saving the desktop when Emacs is killed. Furthermore an anonymous
;; function is added to the `after-init-hook'. This function is
;; responsible for loading the desktop when Emacs is started.
;; Some words on minor modes: Most minor modes are controlled by
;; buffer-local variables, which have a standard save / restore
;; mechanism. To handle all minor modes, we take the following
;; approach: (1) check whether the variable name from
;; `minor-mode-alist' is also a function; and (2) use translation
;; table `desktop-minor-mode-table' in the case where the two names
;; are not the same.
;; By the way: don't use desktop.el to customize Emacs -- the file .emacs
;; in your home directory is used for that. Saving global default values
;; for buffers is an example of misuse.
;; PLEASE NOTE: The kill ring can be saved as specified by the variable
;; `desktop-globals-to-save' (by default it isn't). This may result in saving
;; things you did not mean to keep. Use M-x desktop-clear RET.
