+;;; Commentary:
+
+;; win32-win.el:  this file is loaded from ../lisp/startup.el when it recognizes
+;; that win32 windows are to be used.  Command line switches are parsed and those
+;; pertaining to win32 are processed and removed from the command line.  The
+;; win32 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).
+
+;;; Code:
+
+
+;; These are the standard X switches from the Xt Initialize.c file of
+;; Release 4.
+
+;; Command line		Resource Manager string
+
+;; +rv			*reverseVideo
+;; +synchronous		*synchronous
