| 26 | WARNING:
|
|---|
| 27 |
|
|---|
| 28 | This program and library (attempts to) compress data by
|
|---|
| 29 | performing several non-trivial transformations on it.
|
|---|
| 30 | Unless you are 100% familiar with *all* the algorithms
|
|---|
| 31 | contained herein, and with the consequences of modifying them,
|
|---|
| 32 | you should NOT meddle with the compression or decompression
|
|---|
| 33 | machinery. Incorrect changes can and very likely *will*
|
|---|
| 34 | lead to disastrous loss of data.
|
|---|
| 35 |
|
|---|
| 36 |
|
|---|
| 37 | DISCLAIMER:
|
|---|
| 38 |
|
|---|
| 39 | I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
|
|---|
| 40 | USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.
|
|---|
| 41 |
|
|---|
| 42 | Every compression of a file implies an assumption that the
|
|---|
| 43 | compressed file can be decompressed to reproduce the original.
|
|---|
| 44 | Great efforts in design, coding and testing have been made to
|
|---|
| 45 | ensure that this program works correctly. However, the complexity
|
|---|
| 46 | of the algorithms, and, in particular, the presence of various
|
|---|
| 47 | special cases in the code which occur with very low but non-zero
|
|---|
| 48 | probability make it impossible to rule out the possibility of bugs
|
|---|
| 49 | remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS
|
|---|
| 50 | PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
|
|---|
| 51 | SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
|
|---|
| 52 |
|
|---|
| 53 | That is not to say this program is inherently unreliable.
|
|---|
| 54 | Indeed, I very much hope the opposite is true. bzip2/libbzip2
|
|---|
| 55 | has been carefully constructed and extensively tested.

|

| 58 | PATENTS:
|
|---|
| 59 |
|
|---|
| 60 | To the best of my knowledge, bzip2/libbzip2 does not use any
|
|---|
| 61 | patented algorithms. However, I do not have the resources
|
|---|
| 62 | to carry out a patent search. Therefore I cannot give any
|
|---|
| 63 | guarantee of the above statement.
|

| 64 |
|
|---|
| 65 |
|
|---|
| 66 | I hope you find bzip2 useful. Feel free to contact me at
|
|---|
| 67 | jseward@bzip.org
|
|---|
| 68 | if you have any suggestions or queries. Many people mailed me with
|
|---|
| 69 | comments, suggestions and patches after the releases of bzip-0.15,
|
|---|
| 70 | bzip-0.21, and bzip2 versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1,
|
|---|
| 71 | 1.0.2 and 1.0.3, and the changes in bzip2 are largely a result of this
|
|---|
| 72 | feedback. I thank you for your comments.
