NAME

       libbz2 - library for block-sorting data compression

SYNOPSIS

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

       #include <stdio.h>
       #include <bzlib.h>

DESCRIPTION

       Interfaces  in  this library provide the ability to compress (and decompress) files using the Burrows-Wheeler blocksorting 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.
