 # Driver model
 
-Currently gui.cs is built on top of curses, but the console driver has
-been abstracted, an implementation that uses `System.Console` is
-possible, but would have to emulate some of the behavior of curses,
-namely that operations are performed on the buffer, and the Refresh
-call reflects the contents of an internal buffer into the screen and
-position the cursor in the last set position at the end.
+Currently gui.cs has support for both ncurses and the `System.Console`
