From llzip-0.03/README:
llzip is a hack on my lbzip2-0.17 release. I ripped out the
decompression stuff, and replaced the bzip2 compression with
the lzma compression from lzlib-0.7. llzip is mainly meant
as an assisted fork point for the lzip developers.
Nonetheless, I tried to review the diff against lbzip2-0.17
thoroughly, and I think llzip should be usable on its own
until something better appears on the net.
