# (blino) modified for 443, from sqlzma1-449.patch:
#   * adapted to lzma443 dist structure: s,/C/Compress/Lzma/,/C/7zip/Compress/LZMA_C/,; s,/CPP/7zip/Compress/LZMA_Alone/,/C/7zip/Compress/LZMA_Alone/,
#   * use sqlzma.mk makefiles for 443 (from from sqlzma1-443.patch)
#   * remove NCoderPropID::kNumThreads in comp.cc, it is invalid since we don't build LZMAEncoder.cpp with COMPRESS_MF_MT multithread support

%description
LZMA provides very high compression ratio and fast decompression. The
core of the LZMA utils is Igor Pavlov's LZMA SDK containing the actual
LZMA encoder/decoder. LZMA utils add a few scripts which provide
gzip-like command line interface and a couple of other LZMA related
tools. Also provides:

- Average compression ratio 30% better than that of gzip and 15%
  better than that of bzip2.

- Decompression speed is only little slower than that of gzip, being
  two to five times faster than bzip2.

- In fast mode, compresses faster than bzip2 with a comparable
  compression ratio.

- Achieving the best compression ratios takes four to even twelve
  times longer than with bzip2. However. this doesn't affect
  decompressing speed.

- Very similar command line interface than what gzip and bzip2 have.
