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

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

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