+Minilzip is a test program for the compression library lzlib, fully
 compatible with lzip 1.4 or newer.
+.PP
+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 \fB\-0\fR) or
+compress most files more than bzip2 (lzip \fB\-9\fR). 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.

 Exit status: 0 for a normal exit, 1 for environmental problems (file
 not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
 invalid input file, 3 for an internal consistency error (eg, bug) which
 caused minilzip to panic.
+.PP
+The ideas embodied in lzlib 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 range
+encoding), Igor Pavlov (for putting all the above together in LZMA), and
+Julian Seward (for bzip2's CLI).
