 Lunzip is a decompressor for lzip files. It is written in C and its
 small size makes it well suited for embedded devices or software
 installers that need to decompress files but do not need compression

+capabilities. Lunzip is fully compatible with lzip-1.4 or newer.
+
+The lzip file format is designed for long-term data archiving. It is
+clean, provides very safe 4 factor integrity checking, and is backed by
+the recovery capabilities of lziprecover.
 
 Lunzip uses the same well-defined exit status values used by lzip and
 bzip2, which makes it safer when used in pipes or scripts than
 decompressors returning ambiguous warning values, like gunzip.
 
-The 4 factor integrity checking of the lzip format guarantees that the
-decompressed version of the data is identical to the original. This
-guards against corruption of the compressed data, and against undetected
-bugs in lunzip (hopefully very unlikely). The chances of data corruption
-going undetected are microscopic. Be aware, though, that the check

-If you ever need to recover data from a damaged lzip file, try the
-lziprecover program. Lziprecover makes lzip files resistant to bit-flip,
-one of the most common forms of data corruption, and its recovery

 Lunzip replaces every file given in the command line with a decompressed
 version of itself. Each decompressed file has the same modification
 date, permissions, and, when possible, ownership as the corresponding
