%description
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.

XZ Utils consist of several components:

* liblzma is a compression library with API similar to that of zlib.
* xz is a command line tool with syntax similar to that of gzip.
* xzdec is a decompression-only tool smaller than the full-featured xz tool.
* A set of shell scripts (xzgrep, xzdiff, etc.) have been adapted from gzip to
ease viewing, grepping, and comparing compressed files.
* Emulation of command line tools of LZMA Utils eases transition from LZMA
Utils to XZ Utils.
