config EXAMPLES_FBCON
	tristate "Framebuffer console example"
	default n
	---help---
		Enable the Framebuffer console example.
		This example allows STDOUT and/or STDERR to be redirected and displayed
		on a framebuffer character device.

		A chosen builtin app can be spawned - such as "nsh" - to create a
		console and, if required, STDIN can be intercepted to allow input
		characters to be interpreted and pre-processed before passing them
		on to the spawned app.

		Relies on and uses NX and NXFONTS
