27 ;; that W32 windows are to be used. Command line switches are parsed and those
28 ;; pertaining to W32 are processed and removed from the command line. The
29 ;; W32 display is opened and hooks are set for popping up the initial window.
31 ;; startup.el will then examine startup files, and eventually call the hooks
32 ;; which create the first window (s).
