ncompress 4.2.4.2-3 (amd64 binary) in ubuntu lucid

 This package provides the original programs that are the de facto standard, in
 much of the UNIX community, for compressing and uncompressing files. The
 programs implement a fast, simple LZW file compression algorithm. The LZW
 algorithm does not have as high a rate of compression as some other
 algorithms, but LZW implementations such as this one often compress files
 faster than other, similar programs such as gzip.
 .
 For Debian, the standard uncompress program is installed as uncompress.real.
