;; Start Emacs in the root directory of your "project". The desktop saver

+;; 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.
