<CODE>bzip2</CODE> compresses files using the Burrows-Wheeler
|
||
|
|
block-sorting text compression algorithm, and Huffman coding.
|
||
|
|
Compression is generally considerably better than that
|
||
|
|
achieved by more conventional LZ77/LZ78-based compressors,
|
||
|
|
and approaches the performance of the PPM family of statistical compressors.

|

|
<P>
|
||
|
|
<CODE>bzip2</CODE> is built on top of <CODE>libbzip2</CODE>, a flexible library
|
||
|
|
for handling compressed data in the <CODE>bzip2</CODE> format. This manual
|
||
|
|
describes both how to use the program and
|
||
|
|
how to work with the library interface. Most of the
|
||
|
|
manual is devoted to this library, not the program,
|
||
|
|
which is good news if your interest is only in the program.

Chapter 2 describes how to use <CODE>bzip2</CODE>; this is the only part
|
||
|
|
you need to read if you just want to know how to operate the program.
|
||
|
|
Chapter 3 describes the programming interfaces in detail, and
|
||
|
|
Chapter 4 records some miscellaneous notes which I thought
|
||
|
|
ought to be recorded somewhere.
