 Description
 
 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 (up to one single-byte error per member), produce a correct file by
-merging the good parts of two or more damaged copies, reproduce a missing

-decompress files, and test integrity of files.

-To give you an idea of its possibilities, when merging two copies, each of
-them with one damaged area affecting 1 percent of the copy, the probability

 The lziprecover package also includes unzcrash, a program written to test
 robustness to decompression of corrupted data, inspired by unzcrash.c from
 Julian Seward's bzip2. Type 'make unzcrash' in the lziprecover source
