Lziprecover is a data recovery tool and decompressor for files in the 
lzip compressed data format (.lz), 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 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 option "-a, --trailing-error", which makes lziprecover exit 
with error status 2 if any remaining input is detected after 
decompressing the last member, has been added.

  * Decompression time has been reduced by 2%.

  * Up to 6 bytes of trailing data are printed when "-tvvvv" is specified.

  * Dictionary size and size of trailing data (if any) are printed when 
"-lv" is specified.

  * The new chapter "Trailing data" has been added to the manual.

  * A harmless 'make check' failure on Windows, caused by the failed 
comparison of a message in text mode, has been fixed.
