+.SH DESCRIPTION
+.B void 
+is an dummy/null XFree86 input driver.  It doesn't connect to any
+physical device, and it never delivers any events.  It functions as
+both a pointer and keyboard device, and may be used as X server's core
+pointer and/or core keyboard.  It's purpose is to allow the X server
+to operate without a core pointer and/or core keyboard.
+.SH CONFIGURATION DETAILS
+Please refer to XF86Config(__filemansuffix__) for general configuration
+details and for options that can be used with all input drivers.  This
+driver doesn't have any configuration options in addition to those.
