Update of /var/cvs/busybox/scripts/config
In directory winder:/tmp/cvs-serv7481/scripts/config

Added Files:
	.cvsignore Kconfig-language.txt Makefile checklist.c colors.h 
	conf.c confdata.c dialog.h expr.c expr.h inputbox.c 
	lex.zconf.c_shipped lkc.h lkc_proto.h mconf.c menu.c menubox.c 
	msgbox.c symbol.c textbox.c util.c yesno.c zconf.l 
	zconf.tab.c_shipped zconf.tab.h_shipped zconf.y 
Log Message:
Yet another major rework of the BusyBox config system, using the considerably
modified Kbuild system I put into uClibc.  With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system.  I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.
 -Erik

Introduction
------------

The configuration database is collection of configuration options
organized in a tree structure:

	+- Code maturity level options
	|  +- Prompt for development and/or incomplete code/drivers
	+- General setup
	|  +- Networking support
	|  +- System V IPC
	|  +- BSD Process Accounting
	|  +- Sysctl support
	+- Loadable module support
	|  +- Enable loadable module support
	|     +- Set version information on all module symbols
	|     +- Kernel module loader
	+- ...

[...216 lines suppressed...]
	<menu block>
	"endmenu"

This defines a menu block, see "Menu structure" above for more
information. The only possible options are dependencies.

if:

	"if" <expr>
	<if block>
	"endif"

This defines an if block. The dependency expression <expr> is appended
to all enclosed menu entries.

source:

	"source" <prompt>

This reads the specified configuration file. This file is always parsed.
