Please, test it and report any bugs you find.

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, reproduce a missing (zeroed) sector using a reference file, 
extract data from damaged files, decompress files, and test integrity of files.

Lziprecover can remove the damaged members from multimember files, for 
example multimember tar.lz archives.

Lziprecover provides random access to the data in multimember files; it only 
decompresses the members containing the desired data.

Lziprecover facilitates the management of metadata stored as trailing data 
in lzip files.

A nice feature of the lzip format is that a corrupt byte is easier to repair 
the nearer it is from the beginning of the file. Therefore, with the help of 
lziprecover, losing an entire archive just because of a corrupt byte near 
the beginning is a thing of the past.

If the cause of file corruption is a damaged medium, the combination GNU 
ddrescue[1] + lziprecover is the recommended option for recovering data from 
damaged lzip files.

Changes in this version:

  * The debug options '-M, --md5sum' and '-U, --unzcrash' have been added.

  * The option '-E, --debug-reproduce' has been extended to include a 
sector size, and now prints a status line for each sector tested and final 
statistics of the number of sectors reproduced successfully.

  * Lziprecover now does not even open the output file if the input file is 
a terminal.

  * The new sections 'Merging with a backup' and 'Reproducing a mailbox' 
have been added to the manual.

  * The debug options for experts have been documented in the manual.
