      The module compress.lzma of lua-compress provides LZMA compression and
      decompression with liblzma (XZ Utils) for Lua strings and carray objects:
      the formats xz, lzma (legacy .lzma) and raw LZMA1/LZMA2 streams (e.g. of
      7z archives, with their coder properties), in one call or as a stream,
      with presets, the LZMA options, integrity checks, flush modes, memory
      limits and liblzma's status codes. Carrays are read without copying and
      can receive the output directly.
