This library is an implementation of Deflate ([RFC 1951][]) decompression,
|
|
with optional support for ZLIB-style ([RFC 1950][]) and gzip-style
|
|
([RFC 1952][]) wrappers of deflate streams. It currently does not handle
|
|
compression, although this is a natural extension.
|
|
|
|
The implementation should be portable across all ANSI compliant CL
|
|
implementations, but has been optimized mostly for SBCL and CMU CL
|
|
(and other implementations that can generate fast code for word-sized
|
|
integer calculations based on standard type declarations), and
|
|
somewhat (mostly the otherwise very expensive CRC-32 calculations) for
|
|
Lispworks. The performance is still a bit off from zlib/gzip (by a
|
|
factor of around 3-3.5 on my systems), and while much of the
|
|
performance loss is likely to be in the stream-based I/O, a less naive
|
|
implementation of the huffman decoding step is also likely to benefit
|
|
performance a bit.
|
|
|
|
The implementation is licensed under the MIT-style license contained
|
|
in the file COPYING and the header of each source file.
