.SH 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
.BR bzip2(1)
utility.
See
.BR bzip2(1)
for more information.
.LP
The source distribution of bzip2 contains a description of how to
use this library in HTML form.

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.
