.lzma is used for the format output by the "lzma" program that is now
It is recommended to use the newer xz container also based on the lzma
algorithm, hence the "xz" program and .xz extension.
Anyway, recent versions of gnu tar support both. Only xz benefits from a
short option, "-J", clearly favoring it over "--lzma".
One can also pipe xzcat to any version of tar, it's compatible with -J.
