;;; Commentary:

;; X-win.el: this file defines functions to initialize the X window
;; system and process X-specific command line parameters before
;; creating the first X frame.

;; Beginning in Emacs 23, the act of loading this file should not have
;; the side effect of initializing the window system or processing
;; command line arguments (this file is now loaded in loadup.el).  See
;; the variables `handle-args-function-alist' and
;; `window-system-initialization-alist' for more details.

;; startup.el will then examine startup files, and eventually call the hooks
;; which create the first window(s).

;;; Code:

;; These are the standard X switches from the Xt Initialize.c file of
;; Release 4.

;; Command line		Resource Manager string

;; +rv			*reverseVideo
;; +synchronous		*synchronous
;; -background		*background
