NAME
     libbz2 - library for block-sorting data compression

SYNOPSIS
     cc [ flag ...] file -lbz2 [ library ... ]

     #include 
     #include 

DESCRIPTION
     Interfaces in this library provide the ability  to  compress
     (and  decompress) files using the Burrows-Wheeler blocksort-
     ing text compression algorithm, and  Huffman  coding. It  is
     provided  along with the bzip2(1) utility.  See bzip2(1) for
     more information.

     The source distribution of bzip2 contains a  description  of
     how to use this library in HTML form.

     For additional information on shared object interfaces,  see
     intro(3).

     The ideas embodied in bzip2 are due to (at least)  the  fol-
     lowing  people:  Michael Burrows and David Wheeler (for  the
     block  sorting  transformation), David Wheeler  (again,  for
     the  Huffman  coder), Peter Fenwick (for the structured cod-
     ing model in the original bzip, and many  refinements),  and
     Alistair  Moffat,  Radford Neal  and  Ian  Witten  (for  the
     arithmetic  coder  in  the  original  bzip).   I   am   much
     indebted  for  their help, support and advice.  See the man-
     ual  in the source distribution for pointers to  sources  of
     documentation.   Christian  von Roques encouraged me to look
     for  faster sorting algorithms, so as to speed  up  compres-
     sion.   Bela  Lubkin encouraged me to improve the worst-case
     compression performance.  Many people sent  patches,  helped
     with  portability  problems, lent machines, gave advice  and
     were generally helpful.
