.SH DESCRIPTION
|
|
|
20 |
Interfaces in this library provide the ability to compress (and
|
|
|
21 |
decompress) files using the Burrows-Wheeler blocksorting text compression
|
|
|
22 |
algorithm, and Huffman coding. It is provided along with the
|
|
|
23 |
.BR bzip2(1)
|
|
|
24 |
utility.
|
|
|
25 |
See
|
|
|

.BR bzip2(1)
|
|
|

for more information.

The ideas embodied in bzip2 are due to (at least) the fol-
|
|
|
77 |
lowing people: Michael Burrows and David Wheeler (for the
|
|
|
78 |
block sorting transformation), David Wheeler (again, for
|
|
|
79 |
the Huffman coder), Peter Fenwick (for the structured cod-
|
|
|
80 |
ing model in the original bzip, and many refinements), and
|
|
|
81 |
Alistair Moffat, Radford Neal and Ian Witten (for the
|
|
|
82 |
arithmetic coder in the original bzip). I am much
|
|
|
83 |
indebted for their help, support and advice. See the man-
|
|
|
84 |
ual in the source distribution for pointers to sources of
|
|
|
85 |
documentation. Christian von Roques encouraged me to look
|
|
|
86 |
for faster sorting algorithms, so as to speed up compres-
|
|
|
87 |
sion. Bela Lubkin encouraged me to improve the worst-case
|
|
|
88 |
compression performance. Many people sent patches, helped
|
|
|
89 |
with portability problems, lent machines, gave advice and
|
|
|
90 |
were generally helpful.
