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