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. | |

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. | |

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. | |
