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.
