This file is an abridged version of README from bzip2 1.0.4

Build instructions (which are not relevant to busyboxed bzip2)

are removed.

===========================================================
|
|
|
|
|
|
This is the README for bzip2/libzip2.
|
|
This version is fully compatible with the previous public releases.
|
|

------------------------------------------------------------------
|
|
This file is part of bzip2/libbzip2, a program and library for
|
|
lossless, block-sorting data compression.

bzip2/libbzip2 version 1.0.4 of 20 December 2006

Please read and be aware of the following:
|
|
|
|
|
|
WARNING:
|
|
|
|
This program and library (attempts to) compress data by
|
|
performing several non-trivial transformations on it.
|
|
Unless you are 100% familiar with *all* the algorithms
|
|
contained herein, and with the consequences of modifying them,
|
|
you should NOT meddle with the compression or decompression
|
|
machinery. Incorrect changes can and very likely *will*
|
|
lead to disastrous loss of data.
|
|
|
|
|
|
DISCLAIMER:
|
|
|
|
I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
|
|
USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.
|
|
|
|
Every compression of a file implies an assumption that the
|
|
compressed file can be decompressed to reproduce the original.
|
|
Great efforts in design, coding and testing have been made to
|
|
ensure that this program works correctly. However, the complexity
|
|
of the algorithms, and, in particular, the presence of various
|
|
special cases in the code which occur with very low but non-zero
|
|
probability make it impossible to rule out the possibility of bugs
|
|
remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS
|
|
PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
|
|
SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
|
|
|
|
That is not to say this program is inherently unreliable.
|
|
Indeed, I very much hope the opposite is true. bzip2/libbzip2
|
|
has been carefully constructed and extensively tested.
|
|
|
|
|
|
PATENTS:
|
|
|
|
To the best of my knowledge, bzip2/libbzip2 does not use any
|
|
patented algorithms. However, I do not have the resources
|
|
to carry out a patent search. Therefore I cannot give any
|
|
guarantee of the above statement.
|
|
|
|
|
|
I hope you find bzip2 useful. Feel free to contact me at
|
|
jseward@bzip.org
|
|
if you have any suggestions or queries. Many people mailed me with
|
|
comments, suggestions and patches after the releases of bzip-0.15,
|
|
bzip-0.21, and bzip2 versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1,
|
|
1.0.2 and 1.0.3, and the changes in bzip2 are largely a result of this
|
|
feedback. I thank you for your comments.
