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.
