%description
LZMA is an improved version of famous LZ77 compression algorithm. It
was improved in way of maximum increasing of compression ratio,
keeping high decompression speed and low memory requirements for 
decompressing.

LZMA features:
- compressing speed: ~2MB/s on 2 GHz CPU
- decompressing speed:
  - 20-30 MB/s on modern 2 GHz CPU
  - 1-2 MB/s on 200 MHz simple RISC CPU (ARM, MIPS, PowerPC)
- small memory requirements for decompressing: 16 kB + dictionary
  size
- small code size for decompressing: 5-8 kB

LZMA to ulepszona wersja słynnego algorytmu kompresji LZ77. Został
poprawiony, aby maksymalnie zwiększyć stopień kompresji, utrzymując
wysoką szybkość i małe wymagania pamięciowe dekompresji.

Cechy LZMA:
- szybkość kompresowania: ~2MB/s na 2 GHz procesorze,
- szybkość dekompresowania:
  - 20-30 MB/s na współczesnym 2 GHz procesorze,
  - 1-2 MB/s na prostym procesorze RISC 200 MHz (ARM, MIPS, PowerPC)
- mała ilość pamięci potrzebna do dekompresowania: 16 kB + rozmiar
  słownika,
- mały rozmiar kodu dekompresującego: 5-8 kB
