original Lempel-Ziv compress/uncompress programs
This package provides the original compress and uncompress programs that used to be the de facto UNIX standard for compressing and uncompressing files. These programs implement a fast, simple Lempel-Ziv (LZW) file compression algorithm.
For Debian, the standard uncompress program is installed as uncompress.real, to avoid conflicting with other packages.
This package also contains a copyright notice and a brief discussion of the LZW patent history (written by one of the original authors) in the file /usr/share/doc/ncompress/README.Debian.
