+Description
+
+Lzd is a very simplified decompressor for lzip files with an educational
+purpose. Studying its source is a good first step to understand how lzip
+works. It is not safe to use lzd for any real work.
+
+The source of lzd is also used in the lzip manual as a reference
+decompressor in the description of the lzip file format.
+
+Lzd decompresses from standard input to standard output. Lzd will
+correctly decompress the concatenation of two or more compressed files.
+The result is the concatenation of the corresponding decompressed data.
+Integrity of such concatenated compressed input is also verified.
+
+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
+range encoding), and Igor Pavlov (for putting all the above together in
+LZMA).
