| 42 | <CODE>bzip2</CODE> compresses files using the Burrows-Wheeler |
|---|
| 43 | block-sorting text compression algorithm, and Huffman coding. |
|---|
| 44 | Compression is generally considerably better than that |
|---|
| 45 | achieved by more conventional LZ77/LZ78-based compressors, |
|---|
| 46 | and approaches the performance of the PPM family of statistical compressors. |
|---|
| 47 | </P><P> |
|---|
| 48 | |
|---|
| 49 | <CODE>bzip2</CODE> is built on top of <CODE>libbzip2</CODE>, a flexible library |
|---|
| 50 | for handling compressed data in the <CODE>bzip2</CODE> format. This manual |
|---|
| 51 | describes both how to use the program and |
|---|
| 52 | how to work with the library interface. Most of the |
|---|
| 53 | manual is devoted to this library, not the program, |
|---|
| 54 | which is good news if your interest is only in the program. |
|---|
| 55 | </P><P> |
|---|
| 56 | |
|---|
| 57 | Chapter 2 describes how to use <CODE>bzip2</CODE>; this is the only part |
|---|
| 58 | you need to read if you just want to know how to operate the program. |
|---|
| 59 | Chapter 3 describes the programming interfaces in detail, and |
|---|
| 60 | Chapter 4 records some miscellaneous notes which I thought |
|---|
| 61 | ought to be recorded somewhere. |
