From 692d97c380c6dce2c35a04c5dcbce4e831a42fa0 Mon Sep 17 00:00:00 2001 From: "nir.tzachar@gmail.com" Date: Wed, 25 Nov 2009 12:28:43 +0200 Subject: kconfig: new configuration interface (nconfig) This patch was inspired by the kernel projects page, where an ncurses replacement for menuconfig was mentioned (by Sam Ravnborg). Building on menuconfig, this patch implements a more modern look interface using ncurses and ncurses' satellite libraries (menu, panel, form). The implementation does not depend on lxdialog, which is currently distributed with the kernel.
