+Lzip is a lossless data compressor with a user interface similar to the one
+of gzip or bzip2. Lzip uses a simplified form of the 'Lempel-Ziv-Markov
+chain-Algorithm' (LZMA) stream format, chosen to maximize safety and
+interoperability. Lzip can compress about as fast as gzip (lzip -0) or
+compress most files more than bzip2 (lzip -9). Decompression speed is

 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 lziprecover program 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 only help of the lzip manual it would be possible for a

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