%description
LZMA is default and general compression method of 7z format in 7-Zip
program. LZMA provides high compression ratio and very fast
decompression, so it is very suitable for embedded applications. For
example, it can be used for ROM (firmware) compressing.

LZMA features:

- Compressing speed: 500 KB/s on 1 GHz CPU
- Decompressing speed:
  - 8-12 MB/s on 1 GHz Intel Pentium 3 or AMD Athlon.
  - 500-1000 KB/s on 100 MHz ARM, MIPS, PowerPC or other simple RISC
    CPU.
- Small memory requirements for decompressing: 8-32 KB + dictionary
  size
- Small code size for decompressing: 2-8 KB (depending from speed
  optimizations)

LZMA jest domyślnym i ogólnym algorytmem kompresji formatu 7z
stosowanego przez 7-Zip. LZMA zapewnia wysoki stopień kompresji i
bardzo szybką dekompresję, więc nadaje się do zastosowań osadzonych.
Przykładowo, może być użyty do kompresji ROM-u (firmware'u).

Cechy LZMA:

- Szybkość kompresowania: 500 KB/s na 1 GHz procesorze,
- Szybkość dekompresowania:
  - 8-12 MB/s na 1 GHz Pentium 3 lub Athlonie,
  - 500-1000 KB/s na 100 MHz procesorach ARM, MIPS, PowerPC lub innych
    prostych RISC-ach,
- Mała ilość pamięci potrzebna do dekompresowania: 8-32 KB + rozmiar
  słownika,
- Mały rozmiar kodu dekompresującego: 2-8 KB (w zależności od opcji
  optymalizacji).
