25 ;; win32-win.el: this file is loaded from ../lisp/startup.el when it recognizes
|
|
|
26 ;; that win32 windows are to be used. Command line switches are parsed and those
|
|
|
27 ;; pertaining to win32 are processed and removed from the command line. The
|
|
|
28 ;; win32 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).
