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 damaged media, the combination GNU 
ddrescue[1] + lziprecover is the best option for recovering data from 
damaged lzip files.

Changes in this version:

  * In reproduce mode, the input file is now mmapped. This allows 
fixing files larger than available RAM.

  * main.cc: Set a valid invocation_name even if argc == 0.
