function names to conform with the style guide. I also did a lot of work on
the if-then-alse-fi logic and added prototype (i.e. it segfaults when enabled)
line continuation support.
Furthermore, this patch includes Larry Doolittle's work on restructuring some
of the data structures that represent the job and child_program, allowing
several simplifications and fixing several bugs.

BusyBox combines tiny versions of many common UNIX utilities into a single
small executable. It provides minimalist replacements for most of the utilities
you usually find in fileutils, shellutils, findutils, textutils, grep, gzip,
tar, etc. BusyBox provides a fairly complete POSIX environment for any small or
embedded system. The utilities in BusyBox generally have fewer options than
their full featured GNU cousins; however, the options that are included provide
the expected functionality and behave very much like their GNU counterparts.
BusyBox has been written with size-optimization and limited resources in mind.
It is also extremely modular so you can easily include or exclude commands (or
features) at compile time. This makes it easy to customize your embedded
systems. To create a working system, just add a kernel and an editor (such as
e3 (http://www.sax.de/~adlibiti) or elvis-tiny).
BusyBox was originally written to support the Debian Rescue/Install disks, but
it also makes an excellent environment for any small or embedded system.
As of version 0.20 there is now a version number. : ) Also as of version 0.20,
BusyBox is now modularized to easily allow you to build only the components you
need, thereby reducing binary size. To turn off unwanted BusyBox components,
simply edit the file "Config.h" and comment out the components you do not need
using C++ style (//) comments.
After the build is complete, a busybox.links file is generated. This is
used by 'make install' to create symlinks to the busybox binary for all
compiled in functions. By default, 'make install' will place the symlink
forest into `pwd`/_install unless you have defined the PREFIX environment
variable (i.e., make PREFIX="/tmp/foo" install)

For the impatient: To submit a bug, simply send an email describing the problem
to submit@bugs.lineo.com. Bug reports should look something like this:

From: diligent@testing.linux.org
Subject: /bin/true doesn't work
Package: busybox
Version: 0.48
When I invoke '/bin/true' it doesn't work. I expected it to return
a "0" but it returned a "1" instead. Here is the transcript:
$ /bin/true ; echo $?
1
With GNU /bin/true, I get the following output:
$ /bin/true ; echo $?
0
I am using Debian 2.2r2, kernel version 2.2.18, and the latest
uClibc from CVS. Thanks for the wonderful program!

Note the careful description and use of examples showing not only what BusyBox
does, but also a counter example showing what an equivalent GNU app does. Bug
reports lacking such detail may take a _long_ time to be fixed... Thanks for
understanding.
