23 ;;; Commentary:
24
25 ;; w32-win.el: this file is loaded from ../lisp/startup.el when it recognizes
26 ;; that W32 windows are to be used. Command line switches are parsed and those
27 ;; pertaining to W32 are processed and removed from the command line. The
28 ;; W32 display is opened and hooks are set for popping up the initial window.
29
30 ;; startup.el will then examine startup files, and eventually call the hooks
31 ;; which create the first window (s).
