| 27 | ;; win32-win.el: this file is loaded from ../lisp/startup.el when it recognizes |
| 28 | ;; that win32 windows are to be used. Command line switches are parsed and those |
| 29 | ;; pertaining to win32 are processed and removed from the command line. The |
| 30 | ;; win32 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). |
