  27 ;;; Commentary:
  28
  29 ;; ns-win.el: this file is loaded from ../lisp/startup.el when it
  30 ;; recognizes that Nextstep windows are to be used.  Command line
  31 ;; switches are parsed and those pertaining to Nextstep are processed
  32 ;; and removed from the command line.  The Nextstep display is opened
  33 ;; and hooks are set for popping up the initial window.
  34
  35 ;; startup.el will then examine startup files, and eventually call the hooks
  36 ;; which create the first window (s).
  37
  38 ;; A number of other Nextstep convenience functions are defined in
  39 ;; this file, which works in close coordination with src/nsfns.m.
