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). | |
