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.
While liblzma has a zlib-like API, liblzma doesn't include any file I/O \
functions. A separate I/O library is planned, which would abstract handling of \
.gz, .bz2, and .xz files with an easy to use API.
