Thanks Laszlo! + 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. + + +Copyright (C) 2009-2024 Antonio Diaz Diaz. + +This file is a collection of facts, and thus it is not copyrightable, but just +in case, you have unlimited permission to copy, distribute, and modify it. |
