+What is busybox:
+
+  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 bzip2, coreutils, dhcp, diffutils, e2fsprogs,
+  file, findutils, gawk, grep, inetutils, less, modutils, net-tools, procps,
+  sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim.  The utilities
+  in BusyBox often have fewer options than their full-featured cousins;
+  however, the options that are included provide the expected functionality
+  and behave very much like their larger counterparts.
+
+  BusyBox has been written with size-optimization and limited resources in
+  mind, both to produce small binaries and to reduce run-time memory usage.
+  Busybox is also extremely modular so you can easily include or exclude
+  commands (or features) at compile time.  This makes it easy to customize
+  embedded systems; to create a working system, just add /dev, /etc, and a
+  Linux kernel.  Busybox (usually together with uClibc) has also been used as
+  a component of "thin client" desktop systems, live-CD distributions, rescue
+  disks, installers, and so on.
+
+  BusyBox provides a fairly complete POSIX environment for any small system,
+  both embedded environments and more full featured systems concerned about
+  space.  Busybox is slowly working towards implementing the full Single Unix
+  Specification V3 (http://www.opengroup.org/onlinepubs/009695399/), but isn't
+  there yet (and for size reasons will probably support at most UTF-8 for
+  internationalization).  We are also interested in passing the Linux Test
+  Project (http://ltp.sourceforge.net).
+
+----------------
+
+Using busybox:
+
+  BusyBox is extremely configurable.  This allows you to include only the
+  components and options you need, thereby reducing binary size.  Run 'make
+  config' or 'make menuconfig' to select the functionality that you wish to
+  enable.  (See 'make help' for more commands.)
+
+  The behavior of busybox is determined by the name it's called under: as
+  "cp" it behaves like cp, as "sed" it behaves like sed, and so on.  Called
+  as "busybox" it takes the second argument as the name of the applet to
+  run (I.E. "./busybox ls -l /proc").
+
+  The "standalone shell" mode is an easy way to try out busybox; this is a
+  command shell that calls the builtin applets without needing them to be
+  installed in the path.  (Note that this requires /proc to be mounted, if
+  testing from a boot floppy or in a chroot environment.)
+
+  The build automatically generates a file "busybox.links", which is used by
+  'make install' to create symlinks to the BusyBox binary for all compiled in
+  commands.  This uses the PREFIX environment variable to specify where to
+  install, and installs hardlinks or symlinks depending on the configuration
+  preferences.  (You can also manually run the install script at
+  "applets/install.sh").

+
+  The developers also have a bug and patch tracking system
+  (http://bugs.busybox.net) although posting a bug/patch to the mailing list
+  is generally a faster way of getting it fixed, and the complete archive of

+
+getting help:
+
+  when you find you need help, you can check out the busybox mailing list
+  archives at http://busybox.net/lists/busybox/ or even join
+  the mailing list if you are interested.
+
+----------------
+
+bugs:
+
+  if you find bugs, please submit a detailed bug report to the busybox mailing
+  list at busybox@busybox.net.  a well-written bug report should include a
+  transcript of a shell session that demonstrates the bad behavior and enables
+  anyone else to duplicate the bug on their own machine. the following is such
+  an example:
+
+    to: busybox@busybox.net
+    from: diligent@testing.linux.org
+    subject: /bin/date doesn't work
+
+    package: busybox
+    version: 1.00
+
+    when i execute busybox 'date' it produces unexpected results.
+    with gnu date i get the following output:
+
+        $ date
+        fri oct  8 14:19:41 mdt 2004
+
+    but when i use busybox date i get this instead:
+
+        $ date
+        illegal instruction
+
+    i am using debian unstable, kernel version 2.4.25-vrs2 on a netwinder,
+    and the latest uclibc from cvs.  thanks for the wonderful program!
+
+        -diligent
+
+  note the careful description and use of examples showing not only what
+  busybox does, but also a counter example showing what an equivalent app
+  does (or pointing to the text of a relevant standard).  Bug reports lacking
+  such detail may never be fixed...  Thanks for understanding.
+
+----------------
+
+Portability:
+
+  Busybox is developed and tested on Linux 2.4 and 2.6 kernels, compiled
+  with gcc (the unit-at-a-time optimizations in version 3.4 and later are
+  worth upgrading to get, but older versions should work), and linked against
+  uClibc (0.9.27 or greater) or glibc (2.2 or greater).  In such an
+  environment, the full set of busybox features should work, and if
+  anything doesn't we want to know about it so we can fix it.
+
+  There are many other environments out there, in which busybox may build
+  and run just fine.  We just don't test them.  Since busybox consists of a
+  large number of more or less independent applets, portability is a question
+  of which features work where.  Some busybox applets (such as cat and rm) are
+  highly portable and likely to work just about anywhere, while others (such as
+  insmod and losetup) require recent Linux kernels with recent C libraries.
+
+  Earlier versions of Linux and glibc may or may not work, for any given
+  configuration.  Linux 2.2 or earlier should mostly work (there's still
+  some support code in things like mount.c) but this is no longer regularly
+  tested, and inherently won't support certain features (such as long files
+  and --bind mounts).  The same is true for glibc 2.0 and 2.1: expect a higher
+  testing and debugging burden using such old infrastructure.  (The busybox
+  developers are not very interested in supporting these older versions, but
+  will probably accept small self-contained patches to fix simple problems.)
+
+  Some environments are not recommended.  Early versions of uClibc were buggy
+  and missing many features: upgrade.  Linking against libc5 or dietlibc is
+  not supported and not interesting to the busybox developers.  (The first is
+  obsolete and has no known size or feature advantages over uClibc, the second
+  has known bugs that its developers have actively refused to fix.)  Ancient
+  Linux kernels (2.0.x and earlier) are similarly uninteresting.
+
+  In theory it's possible to use Busybox under other operating systems (such as
+  MacOS X, Solaris, Cygwin, or the BSD Fork Du Jour).  This generally involves
+  a different kernel and a different C library at the same time.  While it
+  should be possible to port the majority of the code to work in one of
+  these environments, don't be suprised if it doesn't work out of the box.  If
+  you're into that sort of thing, start small (selecting just a few applets)
+  and work your way up.
+
+  Shaun Jackman has recently (2005) ported busybox to a combination of newlib
+  and libgloss, and some of his patches have been integrated.  This platform
+  may join glibc/uclibc and Linux as a supported combination with the 1.1
+  release, but is not supported in 1.0.
+
+Supported hardware:
+
+  BusyBox in general will build on any architecture supported by gcc.  We
+  support both 32 and 64 bit platforms, and both big and little endian
+  systems.
+
+  Under 2.4 Linux kernels, kernel module loading was implemented in a
+  platform-specific manner.  Busybox's insmod utility has been reported to
+  work under ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC, S390,
+  SH3/4/5, Sparc, v850e, and x86_64.  Anything else probably won't work.
+
+  The module loading mechanism for the 2.6 kernel is much more generic, and
+  we believe 2.6.x kernel module loading support should work on all
+  architectures supported by the kernel.
