-This is the file README for the gzip distribution, version 1.2.4.
-gzip (GNU zip) is a compression utility designed to be a replacement
-for 'compress'. Its main advantages over compress are much better
-compression and freedom from patented algorithms. The GNU Project
-uses it as the standard compression program for its system.
-gzip currently uses by default the LZ77 algorithm used in zip 2.0.1 (the
-portable pkzip compatible archiver). The gzip format was however
-designed to accommodate several compression algorithms. See below
-for a comparison of zip and gzip.
-gunzip can currently decompress files created by gzip, compress or
-pack. The detection of the input format is automatic. For the
-gzip format, gunzip checks a 32 bit CRC. For pack, gunzip checks the
-uncompressed length. The 'compress' format was not designed to allow
-consistency checks. However gunzip is sometimes able to detect a bad
-.Z file because there is some redundancy in the .Z compression format.
-If you get an error when uncompressing a .Z file, do not assume that
-the .Z file is correct simply because the standard uncompress does not
-complain. This generally means that the standard uncompress does not
-check its input, and happily generates garbage output.
-gzip produces files with a .gz extension. Old versions of gzip
-used the .z extension, which was already used by the 'pack' Huffman
-encoder. gunzip is able to decompress .z files (packed or gzip'ed).
-The data format used by gzip is described in the files deflate-1.1.doc
-and gzip-4.1.doc, available in
-Several planned features are not yet supported (see the file TODO).
-See the file NEWS for a summary of changes since 0.5. See the file
-INSTALL for installation instructions. Some answers to frequently
-asked questions are given in the file INSTALL, please read it. (In
-particular, please don't ask me once more for an /etc/magic entry.)
-WARNING: on several systems, compiler bugs cause gzip to fail, in
-particular when optimization options are on. See the section "Special
-targets" at the end of the INSTALL file for a list of known problems.
-For all machines, use "make check" to check that gzip was compiled
-correctly. Try compiling gzip without any optimization if you have a
-Please send all comments by electronic mail to the gzip maintainer
-<>. Bug reports should be sent to
-<>. They should ideally include:
- * The complete output of "gzip -V" (or the contents of revision.h
- if you can't get gzip to compile)
- * The hardware and operating system (try "uname -a")
- * The compiler used to compile (if it is gcc, use "gcc -v")
- * A description of the bug behavior
- * The input to gzip that triggered the bug
-But first, if you have a problem with a .gz file, *please* make sure that
-the file was downloaded in binary mode. 99% of the problems are due to
-people using ascii mode instead of binary mode. In particular, gopher is
-known to corrupt binary files by considering them as ascii.
-If you send me patches for machines I don't have access to, please test them
-very carefully. gzip is used for backups, it must be extremely reliable.
-The package crypt++.el is highly recommended to manipulate gzip'ed
-file from emacs. It recognizes automatically encrypted and compressed
-files when they are first visited or written. It is available via
-anonymous ftp to [] in /pub/lisp/crypt++.el.
-The same site contains also patches to dired, ange-ftp and info.
-GNU tar 1.11.2 has a -z option to invoke directly gzip, so you don't have to
-patch it. The package
-also supports gzip'ed files.
-The znew and gzexe shell scripts provided with gzip benefit from
-(but do not require) the cpmod utility to transfer file attributes.
-It is available by anonymous ftp on in
-The sample programs zread.c, sub.c and add.c in subdirectory sample
-are provided as examples of useful complements to gzip. Read the
-comments inside each source file. The perl script ztouch is also
-provided as example (not installed by default since it relies on perl).
-gzip is free software, you can redistribute it and/or modify it under
-the terms of the GNU General Public License, a copy of which is
-provided under the name COPYING. The latest version of gzip is always
-available by ftp in, or in any of the prep
-mirror sites:
-- sources in gzip-*.tar (or .shar or .tar.gz).
-- Solaris 2 executables in sparc-sun-solaris2/gzip-binaries-*.tar and
- i486-sun-solaris2/gzip-binaries-*.tar.
-- MSDOS lha self-extracting exe in gzip-*.msdos.exe. Once extracted,
- copy gzip.exe to gunzip.exe and zcat.exe, or use "gzip -d" to decompress.
- gzip386.exe runs much faster but only on 386 and above; it is compiled with
- djgpp 1.10 available in directory
-A VMS executable is available in[.macro32.savesets]gzip-1-*.zip
-(use [.macro32]unzip.exe to extract). A PRIMOS executable is available
-OS/2 executables (16 and 32 bits versions) are available in*-[16,32].zip
-Some ftp servers can automatically make a tar.Z from a tar file. If
-you are getting gzip for the first time, you can ask for a tar.Z file
-instead of the much larger tar file.
-Many thanks to those who provided me with bug reports and feedback.
-See the files THANKS and ChangeLog for more details.
- Note about zip vs. gzip:
-The name 'gzip' was a very unfortunate choice, because zip and gzip
-are two really different programs, although the actual compression and
-decompression sources were written by the same persons. A different
-name should have been used for gzip, but it is too late to change now.
-zip is an archiver: it compresses several files into a single archive
-file. gzip is a simple compressor: each file is compressed separately.
-Both share the same compression and decompression code for the
-'deflate' method. unzip can also decompress old zip archives
-(implode, shrink and reduce methods). gunzip can also decompress files
-created by compress and pack. zip 2.0 and gzip do not support
-compression methods other than deflation. (zip 1.0 supports shrink and
-implode). Better compression methods may be added in future versions
-of gzip. zip will always stick to absolute compatibility with pkzip,
-it is thus constrained by PKWare, which is a commercial company. The
-gzip header format is deliberately different from that of pkzip to
-avoid such a constraint.
-On Unix, gzip is mostly useful in combination with tar. GNU tar
-1.11.2 has a -z option to invoke gzip automatically. "tar -z"
-compresses better than zip, since gzip can then take advantage of
-redundancy between distinct files. The drawback is that you must
-scan the whole tar.gz file in order to extract a single file near
-the end; unzip can directly seek to the end of the zip file. There
-is no overhead when you extract the whole archive anyway.
-If a member of a .zip archive is damaged, other files can still
-be recovered. If a .tar.gz file is damaged, files beyond the failure
-point cannot be recovered. (Future versions of gzip will have
-error recovery features.)
-gzip and gunzip are distributed as a single program. zip and unzip
-are, for historical reasons, two separate programs, although the
-authors of these two programs work closely together in the info-zip
-team. zip and unzip are not associated with the GNU project. The
-latest versions of zip and unzip are always on in directory
-/pub/archiving/zip. The current versions at the time of this gzip
-release were and unzip52.tar.Z.
