+Using Vim as a plugin					*gui-w32-windowid*
+
+When gvim starts up normally, it creates its own top level window.  If you
+pass Vim the command-line option |--windowid| with a decimal or hexadecimal
+value, Vim will create a window that is a child of the window with the given
+ID.  This enables Vim to act as a plugin in another application.  This really
+is a programmer's interface, and is of no use without a supporting application
+to spawn Vim correctly.
