liblzw is a small library that provides an API for reading
LZW compressed (.Z) files. The API is
similar to that of zlib (for reading .gz files) and
libbzip2 (for reading .bz2 files) which themselves
are just like the classical UNIX functions for reading files
(e.g. open/read/fopen/fread/etc...).
The core compression code was taken from the canonical
ncompress program.
Since the compression algorithms were ripped out of the public-domain package
ncompress, liblzw has also been released
into the public-domain for people to do with as they will. Just please send me
bugfixes as you find them :).
See the UNLICENSE file for more details.
All existing patents on the LZW algorithm have
expired world-wide.
So LZW is now patent free.
