+# 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>

+There seems to be a problem with the lxdialog companion utility which is
+built prior to running Menuconfig.  Usually this is an indicator that you
+have upgraded/downgraded your ncurses libraries and did not remove the 
+old ncurses header file(s) in /usr/include or /usr/include/ncurses.
+
+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 
+installed on your machine.
+
+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
+the maintainer <andersen@codepoet.org> or post a message to
+<busybox@oss.lineo.com> for additional assistance.

-=head1 NAME
-
-depmod.pl - a cross platform script to generate kernel module dependency
-		lists which can then be used by modprobe.
-
-=head1 SYNOPSIS
-
-depmod.pl [OPTION]... [FILE]...
-
-Example:
-
-	depmod.pl -F linux/System.map target/lib/modules
-
-=head1 DESCRIPTION
-
-The purpose of this script is to automagically generate a list of of kernel
-module dependancies.  This script produces dependancy lists that should be
-identical to the depmod program from the modutils package.  Unlike the depmod
-binary, however, depmod.pl is designed to be run on your host system, not
-on your target system.
-
-This script was written by David Schleef <ds@schleef.org> to be used in
-conjunction with the BusyBox modprobe applet.
-
-=head1 OPTIONS
-
-=over 4
-
-=item B<-h --help>
-
-This displays the help message.
-
-=item B<-b --basedir>
-
-The base directory uner which the target's modules will be found.  This
-defaults to the /lib/modules directory.
-
-=item B<-k --kernel>
-
-Kernel binary for the target.  You must either supply a kernel binary
-or a kernel symbol file (using the -F option).
-
-=item B<-F --kernelsyms>
-
-Kernel symbol file for the target.  You must supply either a kernel symbol file
-kernel binary for the target (using the -k option).
-
-=item B<-n --stdout>
-
-Write to stdout instead of modules.dep.  This is currently hard coded...
-kernel binary for the target (using the -k option).
-
-=item B<--verbose>
-
-Be verbose (not implemented)

-# /etc/inittab init(8) configuration for BusyBox
-#
-# Copyright (C) 1999 by Lineo, inc.  Written by Erik Andersen
-# <andersen@lineo.com>, <andersee@debian.org>
-#
-#
-# Note, BusyBox init doesn't support runlevels.  The runlevels field is
-# completely ignored by BusyBox init. If you want runlevels, use sysvinit.
-#
-#
-# Format for each entry: <id>:<runlevels>:<action>:<process>
-#
-# <id>: WARNING: This field has a non-traditional meaning for BusyBox init!
-#
-#	The id field is used by BusyBox init to specify the controlling tty for
-#	the specified process to run on.  The contents of this field are
-#	appended to "/dev/" and used as-is.  There is no need for this field to
-#	be unique, although if it isn't you may have strange results.  If this
-#	field is left blank, it is completely ignored.  Also note that if
-#	BusyBox detects that a serial console is in use, then all entries
-#	containing non-empty id fields will _not_ be run.  BusyBox init does
-#	nothing with utmp.  We don't need no stinkin' utmp.
-#
-# <runlevels>: The runlevels field is completely ignored.
-#
-# <action>: Valid actions include: sysinit, respawn, askfirst, wait, once, 
-#                                  ctrlaltdel, and shutdown.
-#
-#       Note: askfirst acts just like respawn, but before running the specified
-#       process it displays the line "Please press Enter to activate this
-#       console." and then waits for the user to press enter before starting
-#       the specified process.
-#
-#       Note: unrecognised actions (like initdefault) will cause init to emit
-#       an error message, and then go along with its business.
-#
-# <process>: Specifies the process to be executed and it's command line.
-#
-# Note: BusyBox init works just fine without an inittab. If no inittab is
-# found, it has the following default behavior:
-#         ::sysinit:/etc/init.d/rcS
-#         ::askfirst:/bin/sh
-#         ::ctrlaltdel:/sbin/reboot
-#         ::shutdown:/sbin/swapoff -a
-#         ::shutdown:/bin/umount -a -r
-# if it detects that /dev/console is _not_ a serial console, it will
-# also run:
-#         tty2::askfirst:/bin/sh
-#         tty3::askfirst:/bin/sh
-#         tty4::askfirst:/bin/sh
-#
-# Boot-time system configuration/initialization script.
-# This is run first except when booting in single-user mode.
-#
-::sysinit:/etc/init.d/rcS
-
-# /bin/sh invocations on selected ttys
-#
-# Note below that we prefix the shell commands with a "-" to indicate to the
-# shell that it is supposed to be a login shell.  Normally this is handled by
-# login, but since we are bypassing login in this case, BusyBox lets you do
-# this yourself...
-#
-# Start an "askfirst" shell on the console (whatever that may be)
-::askfirst:-/bin/sh
-# Start an "askfirst" shell on /dev/tty2-4
-tty2::askfirst:-/bin/sh
-tty3::askfirst:-/bin/sh
-tty4::askfirst:-/bin/sh
-
-# /sbin/getty invocations for selected ttys

+ *  Changes by Clifford Wolf (god@clifford.at)
+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set 
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+/*
+ * Originally by Linus Torvalds.
+ * Smart CONFIG_* processing by Werner Almesberger, Michael Chastain.
+ *
+ * Usage: mkdep cflags -- file ...
+ * 
+ * Read source files and output makefile dependency lines for them.
+ * I make simple dependency lines for #include <*.h> and #include "*.h".
+ * I also find instances of CONFIG_FOO and generate dependencies
+ *    like include/config/foo.h.
+ *
+ * 1 August 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Keith Owens reported a bug in smart config processing.  There used
+ *   to be an optimization for "#define CONFIG_FOO ... #ifdef CONFIG_FOO",
+ *   so that the file would not depend on CONFIG_FOO because the file defines
+ *   this symbol itself.  But this optimization is bogus!  Consider this code:
+ *   "#if 0 \n #define CONFIG_FOO \n #endif ... #ifdef CONFIG_FOO".  Here
+ *   the definition is inactivated, but I still used it.  It turns out this
+ *   actually happens a few times in the kernel source.  The simple way to
+ *   fix this problem is to remove this particular optimization.
+ *
+ * 2.3.99-pre1, Andrew Morton <andrewm@uow.edu.au>
+ * - Changed so that 'filename.o' depends upon 'filename.[cS]'.  This is so that
+ *   missing source files are noticed, rather than silently ignored.
+ *
+ * 2.4.2-pre3, Keith Owens <kaos@ocs.com.au>
+ * - Accept cflags followed by '--' followed by filenames.  mkdep extracts -I
+ *   options from cflags and looks in the specified directories as well as the
+ *   defaults.   Only -I is supported, no attempt is made to handle -idirafter,
+ *   -isystem, -I- etc.
