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 (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 
(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 option '--empty-error', which forces exit status 2 if any empty 
member is found, has been added.

  * The option '--marking-error', which forces exit status 2 if the first 
LZMA byte is non-zero in any member, has been added.

  * The option '--clear-marking', which sets to zero the first LZMA byte of 
each member, has been added.

  * The keyword 'empty' is now recognized in the argument of --dump, 
--remove, and --strip.

  * The option '--repair' has been renamed to '--byte-repair'.

  * The option '--debug-repair' has been renamed to '--debug-byte-repair'.

  * Diagnostics caused by invalid arguments to command line options now 
show the argument and the name of the option.

  * The option '--no-verify' of unzcrash has been renamed to '--no-check'.
