 Lziprecover is a data recovery tool and decompressor for files in the lzip
 compressed data format (.lz). Lziprecover is able to repair slightly damaged
 files, produce a correct file by merging the good parts of two or more
-damaged copies, extract data from damaged files, decompress files and test
-integrity of files.

 Lziprecover can repair perfectly most files with small errors (up to one
 single\-byte error per member), without the need of any extra redundance
