NAME
LZMA - a compression algorithm, based on Lempel Ziv’s compression
method.
SYNOPSIS
lzma <e|d> inputFile outputFile [switches...]
DESCRIPTION
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) compression.
lzma is the default and general compression method of 7z format in
7-Zip program.
FUNCTION LETTERS
e Encode file
d Decode file
b Benchmark
