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.
