-Lzip is a lossless data compressor based on the LZMA algorithm, with

+Lzip is a lossless data compressor with a user interface similar to the
+one of gzip or bzip2. Lzip decompresses almost as fast as gzip and
+compresses more than bzip2, which makes it well suited for software
+distribution and data archiving. Lzip is a clean implementation of the
+LZMA algorithm.
 
    Lzip uses the same well-defined exit status values used by bzip2,
 which makes it safer when used in pipes or scripts than compressors
 returning ambiguous warning values, like gzip.
 
+   The lzip file format is designed for long-term data archiving and
+provides very safe integrity checking. The member trailer stores the
+32-bit CRC of the original data, the size of the original data and the
+size of the member. These values, together with the value remaining in
+the range decoder and the end-of-stream marker, provide a 4 factor
+integrity checking which 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 lzip (hopefully very
+unlikely). The chances of data corruption going undetected are
+microscopic. Be aware, though, that the check occurs upon decompression,
+so it can only tell you that something is wrong. It can't help you
+recover the original uncompressed data.
