"zlib is designed to be a free, general-purpose, legally unencumbered --

use on virtually any computer hardware and operating system. The zlib data

format is itself portable across platforms. Unlike the LZW compression method
|
|
used in Unix compress(1) and in the GIF image format, the compression method
|
|
currently used in zlib essentially never expands the data. (LZW can double or
|
|
triple the file size in extreme cases.) zlib's memory footprint is also
|
|
independent of the input data and can be reduced, if necessary, at some cost

in compression.")

"gzip (GNU zip) is a popular data compression program written by Jean-loup

Gailly for the GNU project. Mark Adler wrote the decompression part.

We developed this program as a replacement for compress because of the Unisys
|
|
and IBM patents covering the LZW algorithm used by compress. These patents
|
|
made it impossible for us to use compress, and we needed a replacement. The
|
|
superior compression ratio of gzip is just a bonus.")

The core of the XZ Utils compression code is based on LZMA SDK, but it has

been modified quite a lot to be suitable for XZ Utils. The primary

compression algorithm is currently LZMA2, which is used inside the .xz

than gzip and 15 % smaller output than bzip2.")
