lzip 1.6~pre2-1 (amd64 binary) in ubuntu karmic

 Lzip is a lossless data compressor based on the LZMA algorithm, with very safe
 integrity checking and a user interface similar to the one of gzip or bzip2.
 .
 Lzip decompresses almost as fast as gzip and compresses better than bzip2,
 which makes it well suited for software distribution and data archiving.
