description:
  This package provides a pure interface for compressing and
  decompressing
  <https://en.wikipedia.org/wiki/LZMA LZMA (Lempel–Ziv–Markov chain algorithm)>
  streams of data represented as lazy @ByteString@s. A
  monadic incremental interface is provided as well. This package
  relies on the <http://tukaani.org/xz/ liblzma C library>.
  .
  The following packages are based on this package and provide
  API support for popular streaming frameworks:
  .
  * </package/lzma-streams lzma-streams> (for </package/io-streams io-streams>)
  .
  * </package/pipes-lzma pipes-lzma> (for </package/pipes pipes>)
  .
  * </package/lzma-conduit lzma-conduit> (for </package/conduit conduit>)
  .
