xzdec binary package in Ubuntu Kinetic amd64

 XZ is the successor to the Lempel-Ziv/Markov-chain Algorithm
 compression format, which provides memory-hungry but powerful
 compression (often better than bzip2) and fast, easy decompression.
 .
 This package provides the xzdec and lzmadec utilities, which write
 the decompressed version of a compressed file to standard output. The
 binaries are very small, so they can be easily stored on small media
 with some compressed files, and they are linked statically against
 liblzma so they can be used on machines without a compatible version
 of liblzma installed. However, they have:
 .
   * no compression support;
   * no support for writing to a file other than standard output;
   * no translated messages;
   * been optimized for size rather than speed.
 .
 For a full-featured xzcat command without these limitations, use
 the xz-utils package instead.
