;;; Commentary:
;; win32-win.el: this file is loaded from ../lisp/startup.el when it recognizes
;; that win32 windows are to be used. Command line switches are parsed and those
;; pertaining to win32 are processed and removed from the command line. The
;; win32 display is opened and hooks are set for popping up the initial window.
;; 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
;; -bd *borderColor
;; -bg *background
;; -bordercolor *borderColor
;; -borderwidth .borderWidth
;; -bw .borderWidth
;; -display .display
;; -fg *foreground
;; -fn *font
;; -font *font
;; -foreground *foreground
;; -geometry .geometry
;; -i .iconType
;; -itype .iconType
;; -iconic .iconic
;; -name .name
;; -reverse *reverseVideo
;; -rv *reverseVideo
;; -selectionTimeout .selectionTimeout
;; -synchronous *synchronous
;; -xrm
;; An alist of X options and the function which handles them. See
;; ../startup.el.
