       lziprecover - recovers data from damaged lzip files

       lziprecover [options] [files]

       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  can  repair  perfectly most files with small errors (up to
       one single-byte error per member), without the need of any extra redun‐
       dance  at  all. Losing an entire archive just because of a corrupt byte
       near the beginning is a thing of the past.

       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.

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

       If no file names are given, or if a file  is  '-',  lziprecover  decom‐
       presses  from  standard  input to standard output.  Numbers may be fol‐
       lowed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024,  M
       = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...

       Exit  status:  0  for a normal exit, 1 for environmental problems (file
       not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt  or
       invalid input file, 3 for an internal consistency error (eg, bug) which
       caused lziprecover to panic.
