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, extract data from damaged files, 
decompress files and test integrity of files.

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.

Lziprecover is not a replacement for regular backups, but a last line of 
defense for the case where the backups are also damaged.

Lziprecover is able to recover or decompress files produced by any of 
the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip 
and pdlzip.

The lzip file format is designed for data sharing and long-term 
archiving, taking into account both data integrity and decoder availability.

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 
multiple damaged copies.

Changes in this version:

  * The options "--dump-tdata", "--remove-tdata", and "--strip-tdata" 
have been added to ease the management of metadata stored as trailing data:

  "--dump-tdata" dumps the trailing data (if any) of one or more regular
  files to standard output.

  "--remove-tdata" removes the trailing data from regular files in place.

  "--strip-tdata" copies one or more regular files to standard output,
  stripping the trailing data (if any) from each file.
