  25 ;;; Commentary:
  26
  27 ;; X-win.el:  this file is loaded from ../lisp/startup.el when it recognizes
  28 ;; that X windows are to be used.  Command line switches are parsed and those
  29 ;; pertaining to X are processed and removed from the command line.  The
  30 ;; X display is opened and hooks are set for popping up the initial window.
  31
  32 ;; startup.el will then examine startup files, and eventually call the hooks
  33 ;; which create the first window (s).
