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.
