Lzip is a lossless data compressor with a user interface similar to the one 
of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0) or 
compress most files more than bzip2 (lzip -9). Decompression speed is 
intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from 
a data recovery perspective. Lzip has been designed, written, and tested 
with great care to replace gzip and bzip2 as the standard general-purpose 
compressed format for unix-like systems.

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

   * The lzip format provides very safe integrity checking and some data
     recovery means. The program lziprecover can repair bit flip errors
     (one of the most common forms of data corruption) in lzip files, and
     provides data recovery capabilities, including error-checked merging
     of damaged copies of a file.

   * The lzip format is as simple as possible (but not simpler). The lzip
     manual provides the source code of a simple decompressor along with a
     detailed explanation of how it works, so that with the only help of the
     lzip manual it would be possible for a digital archaeologist to extract
     the data from a lzip file long after quantum computers eventually
     render LZMA obsolete.

   * Additionally the lzip reference implementation is copylefted, which
     guarantees that it will remain free forever.

Changes in this version:

  * Lzip now reports an error if a file name is empty (lzip -t "").

  * Option '-o, --output' now behaves like '-c, --stdout', but sending the 
output unconditionally to a file instead of to standard output. (Suggested 
by Adam Tuja). See the new description of '-o' in the manual. This change is 
backwards compatible only when compressing one input. Therefore commands like:
  lzip -o foo.lz - bar < foo
must now be split into:
  lzip -o foo.lz - < foo
  lzip bar
or rewritten as:
  lzip - bar < foo > foo.lz

  * The words 'decompressed' and 'compressed' have been replaced with the 
shorter 'out' and 'in' in the verbose output when decompressing or testing.

  * Option '--list' now reports corruption or truncation of the last header 
in a multimenber file specifically instead of showing the generic message 
"Last member in input file is truncated or corrupt."

  * The commands needed to extract files from a tar.lz archive have been 
documented in the manual, in the output of '--help', and in the man page.

  * Several fixes and improvements have been made to the manual.

  * 9 new test files have been added to the testsuite.
