Description

Lzd is a simplified decompressor for the lzip format with an educational
purpose. Studying its source code is a good first step to understand how
lzip works. Lzd is written in C++.

The source code of lzd is used in the lzip manual as a reference
decompressor in the description of the lzip file format. Reading the lzip
manual will help you understand the source code. Lzd is compliant with the
lzip specification; it checks the 3 integrity factors.

The source code of lzd is also used as a reference in the description of the
media type 'application/lzip'.
See http://datatracker.ietf.org/doc/draft-diaz-lzip

Lzd decompresses from standard input to standard output. It accepts (and
ignores) the option '-d' for compatibility with other lzip tools. In
particular, accepting the option '-d' allows lzd to be used as argument to
the option '--lz' of the tools from the zutils package.

Lzd correctly decompresses 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 checked.

The ideas embodied in lzd are due to (at least) the following people:
Abraham Lempel and Jacob Ziv (for the LZ algorithm), Andrei 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).
