Various implementations of the program have been written. The most commonly known is the GNU Project's implementation using Lempel-Ziv coding (LZ77). OpenBSD's version of gzip is actually the compress
program, to which support for the gzip format was added in OpenBSD 3.4. The 'g' in this specific version stands for gratis. FreeBSD, DragonFlyBSD and NetBSD use a BSD-licensed implementation instead of the GNU version; it is actually a command-line interface for zlib intended to be compatible with the GNU implementation's options. These implementations originally come from NetBSD, and supports decompression of bzip2 and the Unix pack(1)
format.
