 The result is the concatenation of the corresponding decompressed data.
 Integrity of such concatenated compressed input is also verified.
 
+The lzip file format is designed for long-term data 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 lzip format is as simple as possible (but not simpler). The
+     lzip manual provides the 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 lzip is copylefted, which guarantees that it will
+     remain free forever.
+
+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.

 The ideas embodied in lzd are due to (at least) the following people:
 Abraham Lempel and Jacob Ziv (for the LZ algorithm), Andrey Markov (for
 the definition of Markov chains), G.N.N. Martin (for the definition of
