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). + + +Copyright (C) 2013-2024 Antonio Diaz Diaz. + +This file is free documentation: you have unlimited permission to copy, +distribute, and modify it. + +The file Makefile.in is a data file used by configure to produce the Makefile. +It has the same copyright owner and permissions that configure itself. |
