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