;; We dispense with most of the point and click UI, reduce the startup noise,
;; configure smooth scolling and a nice theme that's easy on the eyes (zenburn).

;; the toolbar is just a waste of valuable screen estate
;; in a tty tool-bar-mode does not properly auto-load, and is
;; already disabled anyway
(when (fboundp 'tool-bar-mode)

;; the menu bar is mostly useless as well
;; but removing it under OS X doesn't make much sense

;; For daemon mode, with-selected-frame seems to be required.  Normal
;; mode seems to require with-selected-frame to be absent.
