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.

-# This script is used to configure BusyBox.
-#
-# It was inspired by the challenge in the original Configure script
-# to ``do something better'', combined with the actual need to ``do
-# something better'' because the old configure script wasn't flexible
-# enough.
-#
-# Raymond Chen was the original author of Configure.
-# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
-#
-# 050793 - use IFS='@' to get around a bug in a pre-version of bash-1.13
-# with an empty IFS.
-#
-# 030995 (storner@osiris.ping.dk) - added support for tri-state answers,
-# for selecting modules to compile.
-#
-# 180995 Bernhard Kaindl (bkaindl@ping.at) - added dummy functions for
-# use with a config.in modified for make menuconfig.
-#
-# 301195 (boldt@math.ucsb.edu) - added help text support
-#
-# 281295 Paul Gortmaker - make tri_state functions collapse to boolean
-# if module support is not enabled.
-#
-# 010296 Aaron Ucko (ucko@vax1.rockhurst.edu) - fix int and hex to accept
-# arbitrary ranges
-#
-# 150296 Dick Streefland (dicks@tasking.nl) - report new configuration
-# items and ask for a value even when doing a "make oldconfig"
-#
-# 200396 Tom Dyas (tdyas@eden.rutgers.edu) - when the module option is
-# chosen for an item, define the macro <option_name>_MODULE
-#
-# 090397 Axel Boldt (boldt@math.ucsb.edu) - avoid ? and + in regular 
-# expressions for GNU expr since version 1.15 and up use \? and \+.
-#
-# 300397 Phil Blundell (pjb27@cam.ac.uk) - added support for min/max 
-# arguments to "int", allow dep_tristate to take a list of dependencies
-# rather than just one.
-#
-# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
-# texts.
-#
-# 102598 Michael Chastain (mec@shout.net) - put temporary files in
-# current directory, not in /tmp.
-#
-# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
-# - Improve the exit message (Jeff Ronne).
-#
-# 7 October 2000, Ghozlane Toumi, <gtoumi@messel.emse.fr>

-# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
-# new bool, tristate and dep_tristate parameters from the defconfig file.
-# new configuration parameters are marked with '(NEW)' as in make config.
-#
-# 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
-# for string options. They are handled like the int and hex options.
-#
-# 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error 
-# handling
-#
-# 131197 Michael Chastain (mec@shout.net) - output all lines for a
-# choice list, not just the selected one.  This makes the output
-# the same as Configure output, which is important for smart config
-# dependencies.
-#
-# 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
-#
-# 221297 Michael Chastain (mec@shout.net) - make define_bool actually
-# define its arguments so that later tests on them work right.
-#
-# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
-# (complement existing value) when used on virgin uninitialized variables.
-#
-# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
-# texts.
-#
-# 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
-# Remove a /tmp security hole in get_def (also makes it faster).
-# Give uninitialized variables canonical values rather than null value.
-# Change a lot of places to call set_x_info uniformly.
-# Take out message about preparing version (old sound driver cruft).
-#
-# 13 Dec 1998, Riley H Williams <rhw@memalpha.cx>
-# When an error occurs, actually display the error message as well as

-#
-# 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
-# Fix mod_bool to honor $CONFIG_MODULES.
-# Fix dep_tristate to call define_bool when dependency is "n".
-#
-# 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
-# Blow away lxdialog.scrltmp on entry to activate_menu.  This protects
-# against people who use commands like ' ' to select menus.
-#
-# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
-# - Improve the exit message (Jeff Ronne).
-#
-# 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
-# - Support for multiple conditions in dep_tristate().
-# - Implemented new functions: define_tristate(), define_int(), define_hex(),
-#   define_string(), dep_bool().
-# 
-# 22 October 2001, Erik Andersen <andersee@debian.org>

-There seems to be a problem with the lxdialog companion utility which is

-
-It is VERY important that you have only one set of ncurses header files
-and that those files are properly version matched to the ncurses libraries

-
-You may also need to rebuild lxdialog.  This can be done by moving to
-the /usr/src/linux/scripts/lxdialog directory and issuing the 
-"make clean all" command.
-
-If you have verified that your ncurses install is correct, you may email

+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
+	+- ...
+
+Every entry has its own dependencies. These dependencies are used
+to determine the visible of an entry. Any child entry is only
+visible if its parent entry is also visible.
+
+Menu entries
+------------
+
+Most entries define a config option, all other entries help to organize
+them. A single configuration option is defined like this:
+
+config MODVERSIONS
+	bool "Set version information on all module symbols"
+	depends MODULES
+	help
+	  Usually, modules have to be recompiled whenever you switch to a new
+	  kernel.  ...
+
+Every line starts with a key word and can be followed by multiple
+arguments.  "config" starts a new config entry. The following lines
+define attributes for this config option. Attributes can be the type of
+the config option, input prompt, dependencies, help text and default
+values. A config option can be defined multiple times with the same
+name, but every definition can have only a single input prompt and the
+type must not conflict.
+
+Menu attributes
+---------------
+
+A menu entry can have a number of attributes. Not all of them are
+applicable everywhere (see syntax).
+
+- type definition: "bool"/"tristate"/"string"/"hex"/"integer"
+  Every config option must have a type. There are only two basic types:
+  tristate and string, the other types base on these two. The type
+  definition optionally accepts an input prompt, so these two examples
+  are equivalent:
+
+	bool "Networking support"
+  and
+	bool
+	prompt "Networking support"
+
+- input prompt: "prompt" <prompt> ["if" <expr>]
+  Every menu entry can have at most one prompt, which is used to display
+  to the user. Optionally dependencies only for this prompt can be added
+  with "if".
+
+- default value: "default" <symbol> ["if" <expr>]
+  A config option can have any number of default values. If multiple
+  default values are visible, only the first defined one is active.
+  Default values are not limited to the menu entry, where they are
+  defined, this means the default can be defined somewhere else or be
+  overriden by an earlier definition.
+  The default value is only assigned to the config symbol if no other
+  value was set by the user (via the input prompt above). If an input
+  prompt is visible the default value is presented to the user and can
+  be overridden by him.
+  Optionally dependencies only for this default value can be added with
+  "if".
+
+- dependencies: "depends on"/"requires" <expr>
+  This defines a dependency for this menu entry. If multiple
+  dependencies are defined they are connected with '&&'. Dependencies
+  are applied to all other options within this menu entry (which also
+  accept "if" expression), so these two examples are equivalent:
+
+	bool "foo" if BAR
+	default y if BAR
+  and
+	depends on BAR
+	bool "foo"
+	default y
+
+- help text: "help"
+  This defines a help text. The end of the help text is determined by
+  the level indentation, this means it ends at the first line which has
+  a smaller indentation than the first line of the help text.
+
+
+Menu dependencies
+-----------------
+
+Dependencies define the visibility of a menu entry and can also reduce
+the input range of tristate symbols. The tristate logic used in the
+expressions uses one more state than normal boolean logic to express the
+module state. Dependency expressions have the following syntax:
+
+<expr> ::= <symbol>                             (1)
+           <symbol> '=' <symbol>                (2)
+           <symbol> '!=' <symbol>               (3)
+           '(' <expr> ')'                       (4)
+           '!' <expr>                           (5)
+           <expr> '||' <expr>                   (6)
+           <expr> '&&' <expr>                   (7)
+
+Expressions are listed in decreasing order of precedence. 
+
+(1) Convert the symbol into an expression. Boolean and tristate symbols
+    are simply converted into the respective expression values. All
+    other symbol types result in 'n'.
+(2) If the values of both symbols are equal, it returns 'y',
+    otherwise 'n'.
+(3) If the values of both symbols are equal, it returns 'n',
+    otherwise 'y'.
+(4) Returns the value of the expression. Used to override precedence.
+(5) Returns the result of (2-/expr/).
+(6) Returns the result of min(/expr/, /expr/).
+(7) Returns the result of max(/expr/, /expr/).
+
+An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
+respectively for calculations). A menu entry becomes visible when it's
+expression evaluates to 'm' or 'y'.
+
+There are two type of symbols: constant and nonconstant symbols.
+Nonconstant symbols are the most common ones and are defined with the
+'config' statement. Nonconstant symbols consist entirely of alphanumeric
+characters or underscores.
+Constant symbols are only part of expressions. Constant symbols are
+always surrounded by single or double quotes. Within the quote any
+other character is allowed and the quotes can be escaped using '\'.
+
+Menu structure
+--------------
+
+The position of a menu entry in the tree is determined in two ways. First
+it can be specified explicitely:
+
+menu "Network device support"
+	depends NET
+
+config NETDEVICES
+	...
+
+endmenu
+
+All entries within the "menu" ... "endmenu" block become a submenu of
+"Network device support". All subentries inherit the dependencies from
+the menu entry, e.g. this means the dependency "NET" is added to the
+dependency list of the config option NETDEVICES.
+
+The other way to generate the menu structure is done by analyzing the
+dependencies. If a menu entry somehow depends on the previous entry, it
+can be made a submenu of it. First the the previous (parent) symbol must
+be part of the dependency list and then one of these two condititions
+must be true:
+- the child entry must become invisible, if the parent is set to 'n'
+- the child entry must only be visible, if the parent is visible
+
+config MODULES
+	bool "Enable loadable module support"
+
+config MODVERSIONS
+	bool "Set version information on all module symbols"
+	depends MODULES
+
+comment "module support disabled"
+	depends !MODULES
+
+MODVERSIONS directly depends on MODULES, this means it's only visible if
+MODULES is different from 'n'. The comment on the other hand is always
+visible when MODULES it's visible (the (empty) dependency of MODULES is
+also part of the comment dependencies).
+
+
+Kconfig syntax
+--------------
+
+The configuration file describes a series of menu entries, where every
+line starts with a keyword (except help texts). The following keywords
+end a menu entry:
+- config
+- choice/endchoice
+- comment
+- menu/endmenu
+- if/endif
+- source
+The first four also start the definition of a menu entry.
+
+config:
+
+	"config" <symbol>
+	<config options>
+
+This defines a config symbol <symbol> and accepts any of above
+attributes as options.
+
+choices:
+
+	"choice"
+	<choice options>
+	<choice block>
+	"endchoice"
+
+This defines a choice group and accepts any of above attributes as
+options. A choice can only be of type bool or tristate, while a boolean
+choice only allows a single config entry to be selected, a tristate
+choice also allows any number of config entries to be set to 'm'. This
+can be used if multiple drivers for a single hardware exists and only a
+single driver can be compiled/loaded into the kernel, but all drivers
+can be compiled as modules.
+A choice accepts another option "optional", which allows to set the
+choice to 'n' and no entry needs to be selected.
+
+comment:
+
+	"comment" <prompt>
+	<comment options>
+
+This defines a comment which is displayed to the user during the
+configuration process and is also echoed to the output files. The only
+possible options are dependencies.
+
+menu:
+
+	"menu" <prompt>
+	<menu options>
+	<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.
