XZ Utils

 XZ Utils is free general-purpose data compression software with high
compression ratio. XZ Utils were written for POSIX-like systems, but also
work on some not-so-POSIX systems. XZ Utils are the successor to LZMA
Utils.

 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
container format. With typical files, XZ Utils create 30 % smaller output
than gzip and 15 % smaller output than bzip2.
