- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-This is a generic INSTALL file for utilities distributions.
-Some features specific to gzip have been added.
-
-To compile this package:
-
-1. Configure the package for your system. In the directory that this
-file is in, type `./configure'. If you're using `csh' on an old
-version of System V, you might need to type `sh configure' instead to
-prevent `csh' from trying to execute `configure' itself. If you
-are using Ultrix, you might need to type `sh5 configure' to avoid
-bugs in /bin/sh. Note that 'sh -x configure' may give different results
-than 'sh configure', making it difficult to debug configure scripts.
-
-The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation, and
-creates the Makefile(s) (one in each subdirectory of the source
-directory). In some packages it creates a C header file containing
-system-dependent definitions. It also creates a file `config.status'
-that you can run in the future to recreate the current configuration.
-
-Running `configure' takes a minute or two. While it is running, it
-prints some messages that tell what it is doing. If you don't want to
-see the messages, run `configure' with its standard output redirected
-to `/dev/null'; for example, `./configure >/dev/null'.
-
-To compile the package in a different directory from the one
-containing the source code, you must use a version of `make' that
-supports the VPATH variable, such as GNU `make'. `cd' to the directory
-where you want the object files and executables to go and run
-`configure'. `configure' automatically checks for the source code in
-the directory that `configure' is in and in `..'. If for some reason
-`configure' is not in the source code directory that you are
-configuring, then it will report that it can't find the source code.
-In that case, run `configure' with the option `--srcdir=DIR', where
-DIR is the directory that contains the source code.
-
-By default, `make install' will install the package's files in
-/usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify an
-installation prefix other than /usr/local by giving `configure' the option
-`--prefix=PATH'. Alternately, you can do so by consistently giving a value
-for the `prefix' variable when you run `make', e.g.,
- make prefix=/usr/gnu
- make prefix=/usr/gnu install
-
-You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If
-you give `configure' the option `--exec-prefix=PATH' or set the
-`make' variable `exec_prefix' to PATH, the package will use PATH as
-the prefix for installing programs and libraries. Data files and
-documentation will still use the regular prefix. Normally, all files
-are installed using the regular prefix.
-
-Another `configure' option is useful mainly in `Makefile' rules for
-updating `config.status' and `Makefile'. The `--no-create' option
-figures out the configuration for your system and records it in
-`config.status', without actually configuring the package (creating
-`Makefile's and perhaps a configuration header file). Later, you can
-run `./config.status' to actually configure the package. You can also
-give `config.status' the `--recheck' option, which makes it re-run
-`configure' with the same arguments you used before. This option is
-useful if you change `configure'.
-
-`configure' ignores any other arguments that you give it.
-
-If your system requires unusual options for compilation or linking
-that `configure' doesn't know about, you can give `configure' initial
-values for some variables by setting them in the environment. In
-Bourne-compatible shells, you can do that on the command line like
-this:
- CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
-
-For csh compatible shells, you can do something like this:
-
- (setenv CC 'gcc -traditional' ; ./configure)
-
-The `make' variables that you might want to override with environment
-variables when running `configure' are:
-
-(For these variables, any value given in the environment overrides the
-value that `configure' would choose:)
-CC C compiler program.
- Default is `cc', or `gcc' if `gcc' is in your PATH.
-INSTALL Program to use to install files.
- Default is `install' if you have it, `cp' otherwise.
- If you have an non-standard `install', use INSTALL="cp -p"
-
-(For these variables, any value given in the environment is added to
-the value that `configure' chooses:)
-DEFS Configuration options, in the form `-Dfoo -Dbar ...'
-CFLAGS Compiler options, such as `-O -g ...'
-LIBS Libraries to link with, in the form `-lfoo -lbar ...'
-
-If you need to do unusual things to compile the package, we encourage
-you to figure out how `configure' could check whether to do them, and
-mail diffs or instructions to the address given in the README so we
-can include them in the next release.
-
-2. Type `make' to compile the package. If you want, you can override
-the `make' variables CFLAGS and LDFLAGS like this:
-
- make CFLAGS=-O2 LDFLAGS=-s
-
-3. The package comes with self-tests. If you want to run them,
-type `make check'.
-
-4. Type `make install' to install programs, data files, and
-documentation. This creates links between gzip, gunzip and zcat.
-You can create additional links uncompress, ungzip and gzcat if
-you prefer these names. You can also create links to unpack and pcat
-if your system uses packed files by default and you want to transform
-them transparently to gzip'ed files.
-
-If you wish to use only the name gzcat and not overwrite an existing zcat, use:
-
- make ZCAT=gzcat install
-
-The man pages are installed by default with an extension `.1' (one).
-If you want the extension `.l' (lower case L) use:
-
- make manext=l install
-
-If you are using csh or tcsh, you must type `rehash' after `make install'
-to make sure that the command `gzip' will invoke the new executable.
-
-5. You can remove the program binaries and object files from the
-source directory by typing `make clean'. To also remove the
-Makefile(s), the header file containing system-dependent definitions
-(if the package uses one), and `config.status' (all the files that
-`configure' created), type `make distclean'.
-
-The file `configure.in' is used as a template to create `configure' by
-a program called `autoconf'. You will only need it if you want to
-regenerate `configure' using a newer version of `autoconf'.
-
-6. You can add the following lines to your /etc/magic file so that
-file(1), if your system supports it, will recognize files created by
-gzip:
-
-0 string \037\213 gzip compressed data
->2 byte 8 - deflate method
->3 byte &0x1 , ascii
->3 byte &0x2 , continuation
->3 byte &0x4 , extra field
->3 byte &0x8 , original file name
->3 byte &0x10 , comment
->3 byte &0x20 , encrypted
->8 byte 2 , max compression
->8 byte 4 , max speed
-
-If your version of 'file' does not accept octal numbers in strings, replace the
-first line with one of these:
-
-0 short 0x8b1f gzip compressed data
-0 short 0105437 gzip compressed data
-
-0 short 0x1f8b gzip compressed data
-0 short 017613 gzip compressed data
-
-Use the first or second form if your machine is a 386 or a Vax or a
-MIPS configured in little-endian mode or any other little-endian
-machine. Use the third or fourth form on big-endian machines.
-On some systems, the field separators must contain only tabs (no spaces).
-
-7. To rename .z files with the new .gz suffix, you can use or adapt
- the following shell script:
-
-#!/bin/sh
-find . -name '*.z' -type f -print | while read i
-do
- new=`echo "$i" | sed 's/\.z$/.gz/'`
- mv "$i" "$new" || echo Failed renaming $i to $new
-done
-
-If you wish to keep the old .z suffix as default without setting the
-GZIP environment variable to "--suffix .z", you can compile gzip with:
-
- make CFLAGS='-DZ_SUFFIX=\".z\"'
-
-
-8. Special targets
-
-- For MSDOS, OS/2, VMS, Atari, Amiga, Primos, use the makefile or command
- file provided in the appropriate subdirectory. For Turbo C++ 1.0, read
- the warning at the top of Makefile.bor.
-
-- On some systems memcpy() may not work as expected. (Problem found on
- Pyramid only so far.) If you get "crc error" on some .gz files, add
- -DNOMEMCPY to CFLAGS and recompile inflate.o. For example:
- rm -f inflate.o
- make CFLAGS="-O2 -DNOMEMCPY"
-
- The memcpy problem affects only gunzip, not gzip. You can safely define
- -DNOMEMCPY on all systems, but this may degrade performance of gunzip.
-
-- If your system is a pure BSD system but incorrectly links string.h to
- strings.h, you may get undefined mem* and str* symbols. Try recompiling with
-
- make clean
- make CFLAGS="-DNO_STRING_H"
-
-- On some systems (reported on Dec Ultrix), "cc -E" and /lib/cpp behave
- differently. If you have trouble with the default configuration, try:
-
- CPP=/lib/cpp ./configure
- make clean
- make
-
-- On Ultrix, /bin/sh is too buggy. Use "sh5 configure" instead of "configure".
-
-- On Mips Dec Ultrix, gunzip behaves non-deterministically with regard
- to some .gz files. The same command either succeeds or gives a CRC error.
- This problem is still being investigated. The files produced by gzip
- are correct (can reliably be extracted on other systems).
-
-- On Xenix, some preprocessors do not define M_XENIX. You may have to do:
-
- DEFS='-DM_XENIX' ./configure
-
-- On Xenix 2.3.2 for 286, do: make xenix_286
-
-- On Coherent, do: make coherent
-
-- On NeXTstep 3.1, many people (but not all) have had trouble with
- configure. Try first
-
- (setenv DEFS -DNO_UTIME_H; ./configure)
- make test
-
- If this fails, then try "make next". configure should work correctly
- on NeXTstep versions up to 3.0.
-
- To build a gzip package that can run on either the m68k or i386 family,
- use configure then "make next-fat".
-
- On some versions of NeXT, either "cc -finline-functions" or "cc -O4"
- is broken. gzip produces valid .gz files but they are much too large
- because the string matching code misses most matches. Use "cc -O" instead.
-
-- There is an optimization bug in the IRIX 4.0.5 IDO 4.1 assembler which is
- triggered by GCC -O. IDO 4.1.1 should fix this. If you have to use IDO 4.1
- then you can avoid the bug in one of the following ways:
-
- 1. Use SGI CC
- 2. Add the -noasmopt flag to GCC
- 3. Reconfigure GCC with the "mips-sgi-irix4loser" target which effectively
- does the same as specifying "-noasmopt" all by default.
- 4. Don't use -O at all with GCC.
-
-- On Solaris 2.1 for x86, the January 1993 "OEM" compiler release
- generates bad code. This is fixed in the June 1993 "FCS" release.
-
-- on Sparc with SunOS 4.1.1 and the SC1.0 compiler, the optimizer
- works up to -O3 but -O4 does not work.
-
-- MSC 5.1 with -Ox and -DDYN_ALLOC generates bad code in inflate.c.
- The default is static allocation (no DYN_ALLOC) and -Ox works on inflate.c.
- But -Ox does not work on util.c and unlzh.c, so you must use -Oait -Gs.
-
-- The exit() function in Turbo C++ 1.0 seems to be broken. gzip crashes
- even if exit(0) is the first statement in main(). The problem is avoided
- by adding -Dexit=_exit to CFLAGS in Makefile.bor.
-
-- On dnix 5.3 2.2 cc version 2.37c is buggy. Version 2.38d works.
-
-- On an Alliant running Concentrix, cc (even without optimization) generates
- incorrect code. You have to use gcc.
-
-- On Cray running CSOS 1.0 with compiler version dev-125, you must compile
- with the flag "-hnoopt" to avoid an optimizer bug.
-
-- On HPUX, configure can't find a correct install. Use:
-
- INSTALL=/usr/local/bin/bsdinst ./configure

-Current Version: 1.2.4.
-See the file ChangeLog for the details of all changes.
-
-Major changes from 1.2.3 to 1.2.4
-* By default, do not restore file name and timestamp from those saved
- inside the .gz file (behave as 'compress'). Added the --name option
- to force name and timestamp restoration.
-* Accept - as synonym for stdin.
-* Use manlinks=so or ln to support either hard links or .so in man pages
-* Accept foo.gz~ in zdiff.
-* Added support for Windows NT
-* Handle ENAMETOOLONG for strict Posix systems
-* Use --recursive instead of --recurse to comply with Webster and
- the GNU stdandard.
-* Allow installation of shell scripts with a g prefix: make G=g install
-* Install by default zcat as gzcat if gzcat already exists in path.
-* Let zmore behave as more when invoked without parameters (give help)
-* Let gzip --list reject files not in gzip format even with --force.
-* Don't complain about non gzip files for options -rt or -rl.
-* Added advice in INSTALL for several systems.
-
-Major changes from 1.2.2 to 1.2.3

-* Added vms/Readme.vms.
-
-Major changes from 1.2.1 to 1.2.2
-* Fix a compilation error on Sun with cc (worked with gcc).
-
-Major changes from 1.2 to 1.2.1
-* Let zmore act as more if the data is not gzipped.

-* Allow gunzip --suffix "" to attempt decompression on any file
- regardless of its extension if an original name is present.
-* Add support for the SCO compress -H format.
-* gzip --fast now compresses faster (speed close to that of compress)
- with degraded compression ratio (but still better than compress).
- Default level changed to -6 (acts exactly as previous level -5) to
- be a better indication of its placement in the speed/ratio range.
-* Use smart name truncation: 123456789012.c -> 123456789.c.gz
- instead of 12345678901.gz
-* With --force, let zcat pass non gzip'ed data unchanged (zcat == cat)
-* Added the zgrep shell script.

-* Several small changes for portability to old or weird systems.
-* Suppress help message and send compressed data to the terminal when
- gzip is invoked without parameters and without redirection.
-* Add compile option GNU_STANDARD to respect the GNU coding standards:
- with -DGNU_STANDARD, behave as gzip even if invoked under the name gunzip.
-(I don't like the last two changes, which were requested by the FSF.)
-
-Major changes from 1.0.5 to 1.0.6.
-* Let gzexe detect executables that are already gzexe'd.
-* Keep file attributes in znew and gzexe if cpmod is available.

-
-
-Major changes from 1.0.4 to 1.0.5.

-Major changes from 1.0.3 to 1.0.4.
-* Added optimized asm version for 68020.
-* Add support for DJGPP.
-
-* Add support for the Atari ST.
-* Added zforce to rename gzip'ed files with truncated names.
-* Do not install with name uncompress (some systems rely on the
- absence of any check in the old uncompress).
-* Added missing function (fcfree) in msdos/tailor.c
-* Let gunzip handle .tgz files, and let gzip skip them.
-* Added -d option (decompress) for gzexe and try preserving file permissions.
-* Suppress all warnings with -q.

-* ... and many other small changes (see ChangeLog)
-
-
-Major changes from 1.0.2 to 1.0.3
-* Added -K option for znew to keep old .Z files if smaller
-* Added -q option (quiet) to cancel -v in GZIP env variable.
-* Made gzexe safer on systems with filename limitation to 14 chars.
-* Fixed bugs in handling of GZIP env variable and incorrect free with Turbo C.
-
-
-Major changes from 1.0.1 to 1.0.2
-* Added env variable GZIP for default options. Example:
- for sh: GZIP="-8 -v"; export GZIP
- for csh: setenv GZIP "-8 -v"
-* Added support for the Amiga.
-* znew now keeps the old .Z if it is smaller than the .z file.
- This can happen for some large and very redundant files.
-* Do not complain about trailing garbage for record oriented IO (Vax/VMS).
- This implies however that multi-part gzip files are not supported
- on such systems.
-* Added gzexe to compress rarely used executables.
-* Reduce memory usage (required for MSDOS and useful on all systems).
-* Preserve time stamp in znew -P (pipe option) if touch -r works.
-
-
-Major changes from 1.0 to 1.0.1
-* fix trivial errors in the Borland makefile (msdos/Makefile.bor)
-
-
-Major changes from 0.8.2 to 1.0
-* gzip now runs on Vax/VMS
-* gzip will not not overwrite files without -f when using /bin/sh in
- background.
-* Support the test option -t for compressed (.Z) files.
- Allow some data recovery for bad .Z files.
-* Added makefiles for MSDOS (Only tested for MSC, not Borland).
-* still more changes to configure for several systems
-
-
-Major changes from 0.8.1 to 0.8.2:
-* yet more changes to configure for Linux and other systems
-* Allow zcat on a file with multiple links.
-
-
-Major changes from 0.8 to 0.8.1:
-* znew has now a pipe option -P to reduce the disk space requirements,
- but this option does not preserve timestamps.
-* Fixed some #if directives for compilation with TurboC.
-
-
-Major changes from 0.7 to 0.8:
-* gzip can now extract .z files created by 'pack'.
-* configure should no longer believe that every machine is a 386
-* Fix the entry for /etc/magic in INSTALL.
-* Add patch for GNU tar 1.11.1 and a pointer to crypt++.el
-* Uncompress files with multiple links only with -f.
-* Fix for uncompress of .Z files on 16-bit machines
-* Create a correct output name for file names of exactly N-1 chars when
- the system has a limit of N chars.
-
-
-Major changes from 0.6 to 0.7:
-* Use "make check" instead of "make test".
-* Keep time stamp and pass options to gzip in znew.
-* Do not create .z.z files with gzip -r.
-* Allow again gunzip .zip files (was working in 0.5)
-* Allow again compilation with TurboC 2.0 (was working in 0.4)
-

- produced by gzip 0.5 are correct and can be read by gunzip 0.6.
-* gunzip now supports multiple compressed members within a single .z file.
-* Fix the check for i386 in configure.
-* Added "make test" to check for compiler bugs. (gcc -finline-functions
- is broken at least on the NeXT.)
-* Use environment variable PAGER in zmore if it is defined.
-* Accept gzcat in addition to zcat for people having /usr/bin before
- /usr/local/bin in their path.

-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 1.9 (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. Previous 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).
-
-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
-problem.
-
-Please send all comments and bug reports by electronic mail to
-<bug-gzip@gnu.org>.
-
-Bug reports 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
-
-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 roebling.poly.edu [128.238.5.31] in /pub/crypt++.el.
-The same directory 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 ftp.uu.net:/languages/emacs-lisp/misc/jka-compr19.el.Z
-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 gatekeeper.dec.com in
-/.0/usenet/comp.sources.unix/volume11/cpmod.Z.
-
-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 are always
-available by ftp in prep.ai.mit.edu:/pub/gnu, 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
-- 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 omnigate.clarkson.edu:/pub/msdos/djgpp.
-
-A VMS executable is available in ftp.spc.edu:[.macro32.savesets]gzip-1-*.zip
-(use [.macro32]unzip.exe to extract). A PRIMOS executable is available
-in ftp.lysator.liu.se:/pub/primos/run/gzip.run.
-OS/2 executables (16 and 32 bits versions) are available in
-ftp.tu-muenchen.de:/pub/comp/os/os2/archiver/gz*-[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 1.9 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 sources are available by ftp in

-TODO file for gzip.
-
-Some of the planned features include:
-
-- Structure the sources so that the compression and decompression code
- form a library usable by any program, and write both gzip and zip on
- top of this library. This would ideally be a reentrant (thread safe)
- library, but this would degrade performance. In the meantime, you can
- look at the sample program zread.c.
-
- The library should have one mode in which compressed data is sent
- as soon as input is available, instead of waiting for complete
- blocks. This can be useful for sending compressed data to/from interactive
- programs.
-
-- Make it convenient to define alternative user interfaces (in
- particular for windowing environments).
-
-- Support in-memory compression for arbitrarily large amounts of data
- (zip currently supports in-memory compression only for a single buffer.)
-
-- Map files in memory when possible, this is generally much faster
- than read/write. (zip currently maps entire files at once, this
- should be done in chunks to reduce memory usage.)
-
-- Add a super-fast compression method, suitable for implementing
- file systems with transparent compression. One problem is that the
- best candidate (lzrw1) is patented twice (Waterworth 4,701,745
- and Gibson & Graybill 5,049,881). The lzrw series of algorithms
- are available by ftp in ftp.adelaide.edu.au:/pub/compression/lzrw*.
-
-- Add a super-tight (but slow) compression method, suitable for long
- term archives. One problem is that the best versions of arithmetic
- coding are patented (4,286,256 4,295,125 4,463,342 4,467,317
- 4,633,490 4,652,856 4,891,643 4,905,297 4,935,882 4,973,961
- 5,023,611 5,025,258).
-
- Note: I will introduce new compression methods only if they are
- significantly better in either speed or compression ratio than the
- existing method(s). So the total number of different methods should
- reasonably not exceed 3. (The current 9 compression levels are just
- tuning parameters for a single method, deflation.)
-
-- Add optional error correction. One problem is that the current version
- of ecc cannot recover from inserted or missing bytes. It would be
- nice to recover from the most common error (transfer of a binary
- file in ascii mode).
-
-- Add a block size (-b) option to improve error recovery in case of
- failure of a complete sector. Each block could be extracted
- independently, but this reduces the compression ratio.
-
-- Use a larger window size to deal with some large redundant files that
- 'compress' currently handles better than gzip.
-
-- Implement the -e (encrypt) option.
-
-Send comments to <bug-gzip@gnu.org>.

-1. Algorithm
-
-The deflation algorithm used by zip and gzip is a variation of LZ77
-(Lempel-Ziv 1977, see reference below). It finds duplicated strings in
-the input data. The second occurrence of a string is replaced by a
-pointer to the previous string, in the form of a pair (distance,
-length). Distances are limited to 32K bytes, and lengths are limited
-to 258 bytes. When a string does not occur anywhere in the previous
-32K bytes, it is emitted as a sequence of literal bytes. (In this
-description, 'string' must be taken as an arbitrary sequence of bytes,
-and is not restricted to printable characters.)
-
-Literals or match lengths are compressed with one Huffman tree, and
-match distances are compressed with another tree. The trees are stored
-in a compact form at the start of each block. The blocks can have any
-size (except that the compressed data for one block must fit in
-available memory). A block is terminated when zip determines that it
-would be useful to start another block with fresh trees. (This is
-somewhat similar to compress.)
-
-Duplicated strings are found using a hash table. All input strings of
-length 3 are inserted in the hash table. A hash index is computed for
-the next 3 bytes. If the hash chain for this index is not empty, all
-strings in the chain are compared with the current input string, and
-the longest match is selected.
-
-The hash chains are searched starting with the most recent strings, to
-favor small distances and thus take advantage of the Huffman encoding.
-The hash chains are singly linked. There are no deletions from the
-hash chains, the algorithm simply discards matches that are too old.
-
-To avoid a worst-case situation, very long hash chains are arbitrarily
-truncated at a certain length, determined by a runtime option (zip -1
-to -9). So zip does not always find the longest possible match but
-generally finds a match which is long enough.
-
-zip also defers the selection of matches with a lazy evaluation
-mechanism. After a match of length N has been found, zip searches for a
-longer match at the next input byte. If a longer match is found, the
-previous match is truncated to a length of one (thus producing a single
-literal byte) and the longer match is emitted afterwards. Otherwise,
-the original match is kept, and the next match search is attempted only
-N steps later.
-
-The lazy match evaluation is also subject to a runtime parameter. If
-the current match is long enough, zip reduces the search for a longer
-match, thus speeding up the whole process. If compression ratio is more
-important than speed, zip attempts a complete second search even if
-the first match is already long enough.
-
-The lazy match evaluation is not performed for the fastest compression
-modes (speed options -1 to -3). For these fast modes, new strings
-are inserted in the hash table only when no match was found, or
-when the match is not too long. This degrades the compression ratio
-but saves time since there are both fewer insertions and fewer searches.
-
-
-2. gzip file format
-
-The pkzip format imposes a lot of overhead in various headers, which
-are useful for an archiver but not necessary when only one file is
-compressed. gzip uses a much simpler structure. Numbers are in little
-endian format, and bit 0 is the least significant bit.
-A gzip file is a sequence of compressed members. Each member has the
-following structure:
-
-2 bytes magic header 0x1f, 0x8b (\037 \213)
-1 byte compression method (0..7 reserved, 8 = deflate)
-1 byte flags
- bit 0 set: file probably ascii text
- bit 1 set: continuation of multi-part gzip file
- bit 2 set: extra field present
- bit 3 set: original file name present
- bit 4 set: file comment present
- bit 5 set: file is encrypted
- bit 6,7: reserved
-4 bytes file modification time in Unix format
-1 byte extra flags (depend on compression method)
-1 byte operating system on which compression took place
-
-2 bytes optional part number (second part=1)
-2 bytes optional extra field length
-? bytes optional extra field
-? bytes optional original file name, zero terminated
-? bytes optional file comment, zero terminated
-12 bytes optional encryption header
-? bytes compressed data
-4 bytes crc32
-4 bytes uncompressed input size modulo 2^32
-
-The format was designed to allow single pass compression without any
-backwards seek, and without a priori knowledge of the uncompressed
-input size or the available size on the output media. If input does
-not come from a regular disk file, the file modification time is set
-to the time at which compression started.
-
-The time stamp is useful mainly when one gzip file is transferred over
-a network. In this case it would not help to keep ownership
-attributes. In the local case, the ownership attributes are preserved
-by gzip when compressing/decompressing the file. A time stamp of zero
-is ignored.
-
-Bit 0 in the flags is only an optional indication, which can be set by
-a small lookahead in the input data. In case of doubt, the flag is
-cleared indicating binary data. For systems which have different
-file formats for ascii text and binary data, the decompressor can
-use the flag to choose the appropriate format.
-
-The extra field, if present, must consist of one or more subfields,
-each with the following format:
-
- subfield id : 2 bytes
- subfield size : 2 bytes (little-endian format)
- subfield data
-
-The subfield id can consist of two letters with some mnemonic value.
-Please send any such id to <gzip@gnu.org>. Ids with a zero second
-byte are reserved for future use. The following ids are defined:
-
- Ap (0x41, 0x70) : Apollo file type information
-
-The subfield size is the size of the subfield data and does not
-include the id and the size itself. The field 'extra field length' is
-the total size of the extra field, including subfield ids and sizes.
-
-It must be possible to detect the end of the compressed data with any
-compression format, regardless of the actual size of the compressed
-data. If the compressed data cannot fit in one file (in particular for
-diskettes), each part starts with a header as described above, but
-only the last part has the crc32 and uncompressed size. A decompressor
-may prompt for additional data for multipart compressed files. It is
-desirable but not mandatory that multiple parts be extractable
-independently so that partial data can be recovered if one of the
-parts is damaged. This is possible only if no compression state is
-kept from one part to the other. The compression-type dependent flags
-can indicate this.
-
-If the file being compressed is on a file system with case insensitive
-names, the original name field must be forced to lower case. There is
-no original file name if the data was compressed from standard input.
-
-Compression is always performed, even if the compressed file is
-slightly larger than the original. The worst case expansion is
-a few bytes for the gzip file header, plus 5 bytes every 32K block,
-or an expansion ratio of 0.015% for large files. Note that the actual
-number of used disk blocks almost never increases.
-
-The encryption is that of zip 1.9. For the encryption check, the
-last byte of the decoded encryption header must be zero. The time
-stamp of an encrypted file might be set to zero to avoid giving a clue
-about the construction of the random header.

-# Makefile for gzip (GNU zip) -*- Indented-Text -*-
-# This Makefile is for SAS/C 6.3 on the Amiga
-# Don't use it with SAS/C 6.2 or earlier versions. These versions will

-# Made by Carsten Steger (carsten.steger@informatik.tu-muenchen.de)
-
-# Some notes on gzip for the Amiga:
-# Due to a strange implementation of the RAM-Disk on Commodore's part
-# you should not use gzip -r on a directory in the RAM-Disk. To zip all
-# files in a directory 'dir' in the RAM-Disk use something like
-# gzip ram:dir/#? ram:dir/#?/#? ...
-# where the number of '#?'s reflects the depth of the directory 'dir'.
-#
-# Alas, the program has it's full functionality only if you have
-# Kickstart 2.0 or higher installed. This affects the expansion of
-# wildcards and the preservation of file access times. You should use
-# a shell that does wildcard expansion under Kickstart 1.3.

-; Adapted for the Amiga by Carsten Steger <stegerc@informatik.tu-muenchen.de>
-; using the code in match.S.
-; The major change in this code consists of removing all unaligned
-; word accesses, because they cause 68000-based Amigas to crash.
-; For maximum speed, UNALIGNED_OK can be defined in Makefile.sasc.
-; The program will then only run on 68020-based Amigas, though.
-;
-; This code will run with registerized parameters too, unless SAS
-; changes parameter passing conventions between new releases of SAS/C.

- * PURPOSE
- *
- * Output variable-length bit strings. Compression can be done
- * to a file or to memory. (The latter is not supported in this version.)
- *
- * DISCUSSION
- *
- * The PKZIP "deflate" file format interprets compressed file data
- * as a sequence of bits. Multi-bit strings in the file may cross
- * byte boundaries without restriction.
- *
- * The first bit of each byte is the low-order bit.
- *
- * The routines in this file allow a variable-length bit value to
- * be output right-to-left (useful for literal values). For
- * left-to-right output (useful for code strings from the tree routines),
- * the bits must have been reversed first with bi_reverse().
- *
- * For in-memory compression, the compressed bit stream goes directly
- * into the requested output buffer. The input data is read in blocks
- * by the mem_read() function. The buffer is limited to 64K on 16 bit
- * machines.
- *
- * INTERFACE
- *
- * void bi_init (FILE *zipfile)
- * Initialize the bit string routines.
- *
- * void send_bits (int value, int length)
- * Write out a bit string, taking the source bits right to
- * left.
- *
- * int bi_reverse (int value, int length)
- * Reverse the bits of a bit string, taking the source bits left to
- * right and emitting them right to left.
- *
- * void bi_windup (void)
- * Write out any remaining bits in an incomplete byte.
- *
- * void copy_block(char *buf, unsigned len, int header)
- * Copy a stored block to the zip file, storing first the length and
- * its one's complement if requested.

- * PURPOSE
- *
- * Identify new text as repetitions of old text within a fixed-
- * length sliding window trailing behind the new text.
- *
- * DISCUSSION
- *
- * The "deflation" process depends on being able to identify portions
- * of the input text which are identical to earlier input (within a
- * sliding window trailing behind the input currently being processed).
- *
- * The most straightforward technique turns out to be the fastest for
- * most input files: try all possible matches and select the longest.
- * The key feature of this algorithm is that insertions into the string
- * dictionary are very simple and thus fast, and deletions are avoided
- * completely. Insertions are performed at each input character, whereas
- * string matches are performed only when the previous match ends. So it
- * is preferable to spend more time in matches to allow very fast string
- * insertions and avoid deletions. The matching algorithm for small
- * strings is inspired from that of Rabin & Karp. A brute force approach
- * is used to find longer strings when a small match has been found.
- * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- * (by Leonid Broukhis).
- * A previous version of this file used a more sophisticated algorithm
- * (by Fiala and Greene) which is guaranteed to run in linear amortized
- * time, but has a larger average cost, uses more memory and is patented.
- * However the F&G algorithm may be faster for some highly redundant
- * files if the parameter max_chain_length (described below) is too large.
- *
- * ACKNOWLEDGEMENTS
- *
- * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- * I found it in 'freeze' written by Leonid Broukhis.
- * Thanks to many info-zippers for bug reports and testing.
- *
- * REFERENCES
- *
- * APPNOTE.TXT documentation file in PKZIP 1.93a distribution.

- expect this.

- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only

- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns `EOF'.
- Then `optind' is the index in ARGV of the first ARGV-element

- so that those that are not options now come last.)

- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of

-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.

-@unnumbered GNU GENERAL PUBLIC LICENSE
-@center Version 2, June 1991
-
-@display
-Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
-675 Mass Ave, Cambridge, MA 02139, USA
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-@end display
-
-@unnumberedsec Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software---to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
-@iftex
-@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end iftex
-@ifinfo
-@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end ifinfo
-
-@enumerate
-@item
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-@item
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-@item
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-@enumerate a
-@item
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-@item
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-@item
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-@end enumerate
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-@item
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-@enumerate a
-@item
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-@item
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-@item
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-@end enumerate
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-@item
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-@item
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-@item
-If, as a consequence of a court judgment or allegation of patent

-
-It is not the purpose of this section to induce you to infringe any

-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot

-This section is intended to make thoroughly clear what is believed to

-If the distribution and/or use of the Program is restricted in

-@unnumberedsec How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the ``copyright'' line and a pointer to where the full notice is found.

-.TH GZEXE 1
-.SH NAME
-gzexe \- compress executable files in place
-.SH SYNOPSIS
-.B gzexe
-[ name ... ]
-.SH DESCRIPTION
-The
-.I gzexe
-utility allows you to compress executables in place and have them
-automatically uncompress and execute when you run them (at a penalty
-in performance). For example if you execute ``gzexe /bin/cat'' it
-will create the following two files:
-.nf
-.br
- -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat
- -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
-.fi
-/bin/cat~ is the original file and /bin/cat is the self-uncompressing
-executable file. You can remove /bin/cat~ once you are sure that
-/bin/cat works properly.
-.PP
-This utility is most useful on systems with very small disks.
-.SH OPTIONS
-.TP
-.B \-d
-Decompress the given executables instead of compressing them.
-.SH "SEE ALSO"
-gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)
-.SH CAVEATS
-The compressed executable is a shell script. This may create some
-security holes. In particular, the compressed executable relies
-on the PATH environment variable to find
-.I gzip
-and some other utilities
-.I (tail, chmod, ln, sleep).
-.SH "BUGS"
-.I gzexe
-attempts to retain the original file attributes on the compressed executable,
-but you may have to fix them manually in some cases, using
-.I chmod
-or
-.I chown.

-.PU
-.TH GZIP 1 local
-.SH NAME
-gzip, gunzip, zcat \- compress or expand files
-.SH SYNOPSIS
-.ll +8
-.B gzip
-.RB [ " \-acdfhlLnNrtvV19 " ]
-.RB [ \-S\ suffix ]
-[
-.I "name \&..."
-]

-[

-]
-.br
-.B zcat
-.RB [ " \-fhLV " ]
-[
-.I "name \&..."
-]
-.SH DESCRIPTION
-.I Gzip
-reduces the size of the named files using Lempel-Ziv coding (LZ77).
-Whenever possible,
-each file is replaced by one with the extension
-.B "\&.gz,"
-while keeping the same ownership modes, access and modification times.
-(The default extension is
-.B "\-gz"
-for VMS,
-.B "z"
-for MSDOS, OS/2 FAT, Windows NT FAT and Atari.)
-If no files are specified, or if a file name is "-", the standard input is
-compressed to the standard output.
-.I Gzip
-will only attempt to compress regular files.
-In particular, it will ignore symbolic links.
-.PP
-If the compressed file name is too long for its file system,
-.I gzip
-truncates it.
-.I Gzip
-attempts to truncate only the parts of the file name longer than 3 characters.
-(A part is delimited by dots.) If the name consists of small parts only,
-the longest parts are truncated. For example, if file names are limited
-to 14 characters, gzip.msdos.exe is compressed to gzi.msd.exe.gz.
-Names are not truncated on systems which do not have a limit on file name
-length.
-.PP
-By default,
-.I gzip
-keeps the original file name and timestamp in the compressed file. These
-are used when decompressing the file with the
-.B \-N
-option. This is useful when the compressed file name was truncated or
-when the time stamp was not preserved after a file transfer.
-.PP
-Compressed files can be restored to their original form using
-.I gzip -d
-or
-.I gunzip
-or
-.I zcat.
-If the original name saved in the compressed file is not suitable for its
-file system, a new name is constructed from the original one to make it
-legal.
-.PP
-.I gunzip
-takes a list of files on its command line and replaces each
-file whose name ends with .gz, -gz, .z, -z, _z or .Z
-and which begins with the correct magic number with an uncompressed
-file without the original extension.
-.I gunzip
-also recognizes the special extensions
-.B "\&.tgz"
-and
-.B "\&.taz"
-as shorthands for
-.B "\&.tar.gz"
-and
-.B "\&.tar.Z"
-respectively.
-When compressing,
-.I gzip
-uses the
-.B "\&.tgz"
-extension if necessary instead of truncating a file with a
-.B "\&.tar"
-extension.
-.PP
-.I gunzip
-can currently decompress files created by
-.I gzip, zip, compress, compress -H
-or
-.I pack.
-The detection of the input format is automatic. When using
-the first two formats,
-.I gunzip
-checks a 32 bit CRC. For
-.I pack, gunzip
-checks the uncompressed length. The standard
-.I compress
-format was not designed to allow consistency checks. However
-.I gunzip
-is sometimes able to detect a bad .Z file. If you get an error
-when uncompressing a .Z file, do not assume that the .Z file is
-correct simply because the standard
-.I uncompress
-does not complain. This generally means that the standard
-.I uncompress
-does not check its input, and happily generates garbage output.
-The SCO compress -H format (lzh compression method) does not include a CRC
-but also allows some consistency checks.
-.PP
-Files created by
-.I zip
-can be uncompressed by gzip only if they have a single member compressed
-with the 'deflation' method. This feature is only intended to help
-conversion of tar.zip files to the tar.gz format. To extract zip files
-with several members, use
-.I unzip
-instead of
-.I gunzip.
-.PP
-.I zcat
-is identical to
-.I gunzip
-.B \-c.
-(On some systems,
-.I zcat
-may be installed as
-.I gzcat
-to preserve the original link to
-.I compress.)
-.I zcat
-uncompresses either a list of files on the command line or its
-standard input and writes the uncompressed data on standard output.
-.I zcat
-will uncompress files that have the correct magic number whether
-they have a
-.B "\&.gz"
-suffix or not.
-.PP
-.I Gzip
-uses the Lempel-Ziv algorithm used in
-.I zip
-and PKZIP.
-The amount of compression obtained depends on the size of the
-input and the distribution of common substrings.
-Typically, text such as source code or English
-is reduced by 60\-70%.
-Compression is generally much better than that achieved by
-LZW (as used in
-.IR compress ),
-Huffman coding (as used in
-.IR pack ),
-or adaptive Huffman coding
-.RI ( compact ).
-.PP
-Compression is always performed, even if the compressed file is
-slightly larger than the original. The worst case expansion is
-a few bytes for the gzip file header, plus 5 bytes every 32K block,
-or an expansion ratio of 0.015% for large files. Note that the actual
-number of used disk blocks almost never increases.
-.I gzip
-preserves the mode, ownership and timestamps of files when compressing
-or decompressing.
-
-.SH OPTIONS
-.TP
-.B \-a --ascii
-Ascii text mode: convert end-of-lines using local conventions. This option
-is supported only on some non-Unix systems. For MSDOS, CR LF is converted
-to LF when compressing, and LF is converted to CR LF when decompressing.
-.TP
-.B \-c --stdout --to-stdout
-Write output on standard output; keep original files unchanged.
-If there are several input files, the output consists of a sequence of
-independently compressed members. To obtain better compression,
-concatenate all input files before compressing them.
-.TP
-.B \-d --decompress --uncompress
-Decompress.
-.TP
-.B \-f --force
-Force compression or decompression even if the file has multiple links
-or the corresponding file already exists, or if the compressed data
-is read from or written to a terminal. If the input data is not in
-a format recognized by
-.I gzip,
-and if the option --stdout is also given, copy the input data without change
-to the standard ouput: let
-.I zcat
-behave as
-.I cat.
-If
-.B \-f
-is not given,
-and when not running in the background,
-.I gzip
-prompts to verify whether an existing file should be overwritten.
-.TP
-.B \-h --help
-Display a help screen and quit.
-.TP
-.B \-l --list
-For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
-The uncompressed size is given as -1 for files not in gzip format,
-such as compressed .Z files. To get the uncompressed size for such a file,
-you can use:
-
- zcat file.Z | wc -c
-
-In combination with the --verbose option, the following fields are also
-displayed:
-
- method: compression method
- crc: the 32-bit CRC of the uncompressed data
- date & time: time stamp for the uncompressed file
-
-The compression methods currently supported are deflate, compress, lzh
-(SCO compress -H) and pack. The crc is given as ffffffff for a file
-not in gzip format.
-
-With --name, the uncompressed name, date and time are
-those stored within the compress file if present.
-
-With --verbose, the size totals and compression ratio for all files
-is also displayed, unless some sizes are unknown. With --quiet,
-the title and totals lines are not displayed.
-.TP
-.B \-L --license
-Display the
-.I gzip
-license and quit.
-.TP
-.B \-n --no-name
-When compressing, do not save the original file name and time stamp by
-default. (The original name is always saved if the name had to be
-truncated.) When decompressing, do not restore the original file name
-if present (remove only the
-.I gzip
-suffix from the compressed file name) and do not restore the original
-time stamp if present (copy it from the compressed file). This option
-is the default when decompressing.
-.TP
-.B \-N --name
-When compressing, always save the original file name and time stamp; this
-is the default. When decompressing, restore the original file name and
-time stamp if present. This option is useful on systems which have
-a limit on file name length or when the time stamp has been lost after
-a file transfer.
-.TP
-.B \-q --quiet
-Suppress all warnings.
-.TP
-.B \-r --recursive
-Travel the directory structure recursively. If any of the file names
-specified on the command line are directories,
-.I gzip
-will descend into the directory and compress all the files it finds there
-(or decompress them in the case of
-.I gunzip
-).
-.TP
-.B \-S .suf --suffix .suf
-Use suffix .suf instead of .gz. Any suffix can be given, but suffixes
-other than .z and .gz should be avoided to avoid confusion when files
-are transferred to other systems. A null suffix forces gunzip to try
-decompression on all given files regardless of suffix, as in:
-
- gunzip -S "" * (*.* for MSDOS)
-
-Previous versions of gzip used
-the .z suffix. This was changed to avoid a conflict with
-.IR pack "(1)".
-.TP
-.B \-t --test
-Test. Check the compressed file integrity.
-.TP
-.B \-v --verbose
-Verbose. Display the name and percentage reduction for each file compressed
-or decompressed.
-.TP
-.B \-V --version
-Version. Display the version number and compilation options then quit.
-.TP
-.B \-# --fast --best
-Regulate the speed of compression using the specified digit
-.IR # ,
-where
-.B \-1
-or
-.B \-\-fast
-indicates the fastest compression method (less compression)
-and
-.B \-9
-or
-.B \-\-best
-indicates the slowest compression method (best compression).
-The default compression level is
-.BR \-6
-(that is, biased towards high compression at expense of speed).
-.SH "ADVANCED USAGE"
-Multiple compressed files can be concatenated. In this case,
-.I gunzip
-will extract all members at once. For example:
-
- gzip -c file1 > foo.gz
- gzip -c file2 >> foo.gz
-
-Then
- gunzip -c foo
-
-is equivalent to
-
- cat file1 file2
-
-In case of damage to one member of a .gz file, other members can
-still be recovered (if the damaged member is removed). However,
-you can get better compression by compressing all members at once:
-
- cat file1 file2 | gzip > foo.gz
-
-compresses better than
-
- gzip -c file1 file2 > foo.gz
-
-If you want to recompress concatenated files to get better compression, do:
-
- gzip -cd old.gz | gzip > new.gz
-
-If a compressed file consists of several members, the uncompressed
-size and CRC reported by the --list option applies to the last member
-only. If you need the uncompressed size for all members, you can use:
-
- gzip -cd file.gz | wc -c
-
-If you wish to create a single archive file with multiple members so
-that members can later be extracted independently, use an archiver
-such as tar or zip. GNU tar supports the -z option to invoke gzip
-transparently. gzip is designed as a complement to tar, not as a
-replacement.
-.SH "ENVIRONMENT"
-The environment variable
-.B GZIP
-can hold a set of default options for
-.I gzip.
-These options are interpreted first and can be overwritten by
-explicit command line parameters. For example:
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name

-.in +8
-The input file has links; it is left unchanged. See

-flag to force compression of multiply-linked files.
-.in -8
-.SH CAVEATS
-When writing compressed data to a tape, it is generally necessary to
-pad the output with zeroes up to a block boundary. When the data is
-read and the whole block is passed to
-.I gunzip
-for decompression,
-.I gunzip
-detects that there is extra trailing garbage after the compressed data
-and emits a warning by default. You have to use the --quiet option to
-suppress the warning. This option can be set in the
-.B GZIP
-environment variable as in:
- for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
- for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0
-
-In the above example, gzip is invoked implicitly by the -z option of
-GNU tar. Make sure that the same block size (-b option of tar) is used
-for reading and writing compressed data on tapes. (This example
-assumes you are using the GNU version of tar.)
-.SH BUGS
-The --list option reports incorrect sizes if they exceed 2 gigabytes.
-The --list option reports sizes as -1 and crc as ffffffff if the
-compressed file is on a non seekable media.
-
-In some rare cases, the --best option gives worse compression than
-the default compression level (-6). On some highly redundant files,
-.I compress
-compresses better than
-.I gzip.

-NAME
- gzip, gunzip, zcat - compress or expand files
-
-SYNOPSIS
- gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
- gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
- zcat [ -fhLV ] [ name ... ]
-
-DESCRIPTION
- Gzip reduces the size of the named files using Lempel-Ziv
- coding (LZ77). Whenever possible, each file is replaced by
- one with the extension .gz, while keeping the same ownership
- modes, access and modification times. (The default exten-
- sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT
- and Atari.) If no files are specified, or if a file name is
- "-", the standard input is compressed to the standard out-
- put. Gzip will only attempt to compress regular files. In
- particular, it will ignore symbolic links.
-
- If the compressed file name is too long for its file system,
- gzip truncates it. Gzip attempts to truncate only the parts
- of the file name longer than 3 characters. (A part is del-
- imited by dots.) If the name consists of small parts only,
- the longest parts are truncated. For example, if file names
- are limited to 14 characters, gzip.msdos.exe is compressed
- to gzi.msd.exe.gz. Names are not truncated on systems which
- do not have a limit on file name length.
-
- By default, gzip keeps the original file name and timestamp
- in the compressed file. These are used when decompressing
- the file with the -N option. This is useful when the
- compressed file name was truncated or when the time stamp
- was not preserved after a file transfer.
-
- Compressed files can be restored to their original form
- using gzip -d or gunzip or zcat. If the original name saved
- in the compressed file is not suitable for its file system,
- a new name is constructed from the original one to make it
- legal.
-
- gunzip takes a list of files on its command line and
- replaces each file whose name ends with .gz, -gz, .z, -z, _z
- or .Z and which begins with the correct magic number with an
- uncompressed file without the original extension. gunzip
- also recognizes the special extensions .tgz and .taz as
- shorthands for .tar.gz and .tar.Z respectively. When
- compressing, gzip uses the .tgz extension if necessary
- instead of truncating a file with a .tar extension.
-
- gunzip can currently decompress files created by gzip, zip,
- compress, compress -H or pack. The detection of the input
- format is automatic. When using the first two formats,
- gunzip checks a 32 bit CRC. For pack, gunzip checks the
- uncompressed length. The standard compress format was not
- designed to allow consistency checks. However gunzip is
- sometimes able to detect a bad .Z file. 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 out-
- put. The SCO compress -H format (lzh compression method)
- does not include a CRC but also allows some consistency
- checks.
-
- Files created by zip can be uncompressed by gzip only if
- they have a single member compressed with the 'deflation'
- method. This feature is only intended to help conversion of
- tar.zip files to the tar.gz format. To extract zip files
- with several members, use unzip instead of gunzip.
-
- zcat is identical to gunzip -c. (On some systems, zcat may
- be installed as gzcat to preserve the original link to
- compress.) zcat uncompresses either a list of files on the
- command line or its standard input and writes the
- uncompressed data on standard output. zcat will uncompress
- files that have the correct magic number whether they have a
- .gz suffix or not.
-
- Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP.
- The amount of compression obtained depends on the size of
- the input and the distribution of common substrings. Typi-
- cally, text such as source code or English is reduced by
- 60-70%. Compression is generally much better than that
- achieved by LZW (as used in compress), Huffman coding (as
- used in pack), or adaptive Huffman coding (compact).
-
- Compression is always performed, even if the compressed file
- is slightly larger than the original. The worst case expan-
- sion is a few bytes for the gzip file header, plus 5 bytes
- every 32K block, or an expansion ratio of 0.015% for large
- files. Note that the actual number of used disk blocks
- almost never increases. gzip preserves the mode, ownership
- and timestamps of files when compressing or decompressing.
-
-OPTIONS
- -a --ascii
- Ascii text mode: convert end-of-lines using local con-
- ventions. This option is supported only on some non-
- Unix systems. For MSDOS, CR LF is converted to LF when
- compressing, and LF is converted to CR LF when
- decompressing.
-
- -c --stdout --to-stdout
- Write output on standard output; keep original files
- unchanged. If there are several input files, the out-
- put consists of a sequence of independently compressed
- members. To obtain better compression, concatenate all
- input files before compressing them.
-
- -d --decompress --uncompress
- Decompress.
-
- -f --force
- Force compression or decompression even if the file has
- multiple links or the corresponding file already
- exists, or if the compressed data is read from or writ-
- ten to a terminal. If the input data is not in a format
- recognized by gzip, and if the option --stdout is also
- given, copy the input data without change to the stan-
- dard ouput: let zcat behave as cat. If -f is not given,
- and when not running in the background, gzip prompts to
- verify whether an existing file should be overwritten.
-
- -h --help
- Display a help screen and quit.
-
- -l --list
- For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
- The uncompressed size is given as -1 for files not in
- gzip format, such as compressed .Z files. To get the
- uncompressed size for such a file, you can use:
-
- zcat file.Z | wc -c
-
- In combination with the --verbose option, the following
- fields are also displayed:
-
- method: compression method
- crc: the 32-bit CRC of the uncompressed data
- date & time: time stamp for the uncompressed file
-
- The compression methods currently supported are
- deflate, compress, lzh (SCO compress -H) and pack. The
- crc is given as ffffffff for a file not in gzip format.
-
- With --name, the uncompressed name, date and time are
- those stored within the compress file if present.
-
- With --verbose, the size totals and compression ratio
- for all files is also displayed, unless some sizes are
- unknown. With --quiet, the title and totals lines are
- not displayed.
-
- -L --license
- Display the gzip license and quit.
-
- -n --no-name
- When compressing, do not save the original file name
- and time stamp by default. (The original name is always
- saved if the name had to be truncated.) When
- decompressing, do not restore the original file name if
- present (remove only the gzip suffix from the
- compressed file name) and do not restore the original
- time stamp if present (copy it from the compressed
- file). This option is the default when decompressing.
-
- -N --name
- When compressing, always save the original file name
- and time stamp; this is the default. When decompress-
- ing, restore the original file name and time stamp if
- present. This option is useful on systems which have a
- limit on file name length or when the time stamp has
- been lost after a file transfer.
-
- -q --quiet
- Suppress all warnings.
-
- -r --recursive
- Travel the directory structure recursively. If any of
- the file names specified on the command line are direc-
- tories, gzip will descend into the directory and
- compress all the files it finds there (or decompress
- them in the case of gunzip ).
-
- -S .suf --suffix .suf
- Use suffix .suf instead of .gz. Any suffix can be
- given, but suffixes other than .z and .gz should be
- avoided to avoid confusion when files are transferred
- to other systems. A null suffix forces gunzip to try
- decompression on all given files regardless of suffix,
- as in:
-
- gunzip -S "" * (*.* for MSDOS)
-
- Previous versions of gzip used the .z suffix. This was
- changed to avoid a conflict with pack(1).
-
- -t --test
- Test. Check the compressed file integrity.
-
- -v --verbose
- Verbose. Display the name and percentage reduction for
- each file compressed or decompressed.
-
- -V --version
- Version. Display the version number and compilation
- options then quit.
-
- -# --fast --best
- Regulate the speed of compression using the specified
- digit #, where -1 or --fast indicates the fastest
- compression method (less compression) and -9 or --best
- indicates the slowest compression method (best compres-
- sion). The default compression level is -6 (that is,
- biased towards high compression at expense of speed).
-
-ADVANCED USAGE
- Multiple compressed files can be concatenated. In this case,
- gunzip will extract all members at once. For example:
-
- gzip -c file1 > foo.gz
- gzip -c file2 >> foo.gz
-
- Then
- gunzip -c foo
-
- is equivalent to
-
- cat file1 file2
-
- In case of damage to one member of a .gz file, other members
- can still be recovered (if the damaged member is removed).
- However, you can get better compression by compressing all
- members at once:
-
- cat file1 file2 | gzip > foo.gz
-
- compresses better than
-
- gzip -c file1 file2 > foo.gz
-
- If you want to recompress concatenated files to get better
- compression, do:
-
- gzip -cd old.gz | gzip > new.gz
-
- If a compressed file consists of several members, the
- uncompressed size and CRC reported by the --list option
- applies to the last member only. If you need the
- uncompressed size for all members, you can use:
-
- gzip -cd file.gz | wc -c
-
- If you wish to create a single archive file with multiple
- members so that members can later be extracted indepen-
- dently, use an archiver such as tar or zip. GNU tar supports
- the -z option to invoke gzip transparently. gzip is designed
- as a complement to tar, not as a replacement.
-
-ENVIRONMENT
- The environment variable GZIP can hold a set of default
- options for gzip. These options are interpreted first and
- can be overwritten by explicit command line parameters. For
- example:
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name
-
- On Vax/VMS, the name of the environment variable is
- GZIP_OPT, to avoid a conflict with the symbol set for invo-
- cation of the program.

-
-DIAGNOSTICS
- Exit status is normally 0; if an error occurs, exit status
- is 1. If a warning occurs, exit status is 2.
-
- Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
- Invalid options were specified on the command line.
- file: not in gzip format
- The file specified to gunzip has not been
- compressed.
- file: Corrupt input. Use zcat to recover some data.
- The compressed file has been damaged. The data up to
- the point of failure can be recovered using
- zcat file > recover
- file: compressed with xx bits, can only handle yy bits
- File was compressed (using LZW) by a program that
- could deal with more bits than the decompress code
- on this machine. Recompress the file with gzip,
- which compresses better and uses less memory.
- file: already has .gz suffix -- no change
- The file is assumed to be already compressed.
- Rename the file and try again.
- file already exists; do you wish to overwrite (y or n)?
- Respond "y" if you want the output file to be
- replaced; "n" if not.
- gunzip: corrupt input
- A SIGSEGV violation was detected which usually means
- that the input file has been corrupted.
- xx.x%
- Percentage of the input saved by compression.
- (Relevant only for -v and -l.)
- -- not a regular file or directory: ignored
- When the input file is not a regular file or direc-
- tory, (e.g. a symbolic link, socket, FIFO, device
- file), it is left unaltered.
- -- has xx other links: unchanged
- The input file has links; it is left unchanged. See
- ln(1) for more information. Use the -f flag to force
- compression of multiply-linked files.
-
-CAVEATS
- When writing compressed data to a tape, it is generally
- necessary to pad the output with zeroes up to a block boun-
- dary. When the data is read and the whole block is passed to
- gunzip for decompression, gunzip detects that there is extra
- trailing garbage after the compressed data and emits a warn-
- ing by default. You have to use the --quiet option to
- suppress the warning. This option can be set in the GZIP
- environment variable as in:
- for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
- for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0
-
- In the above example, gzip is invoked implicitly by the -z
- option of GNU tar. Make sure that the same block size (-b
- option of tar) is used for reading and writing compressed
- data on tapes. (This example assumes you are using the GNU
- version of tar.)
-
-BUGS
- The --list option reports incorrect sizes if they exceed 2
- gigabytes. The --list option reports sizes as -1 and crc as
- ffffffff if the compressed file is on a non seekable media.
-
- In some rare cases, the --best option gives worse compres-
- sion than the default compression level (-6). On some highly
- redundant files, compress compresses better than gzip.

-@chapter Overview
-@cindex overview
-
-@code{gzip} reduces the size of the named files using Lempel-Ziv coding
-(LZ77). Whenever possible, each file is replaced by one with the
-extension @samp{.gz}, while keeping the same ownership modes, access and
-modification times. (The default extension is @samp{-gz} for VMS,
-@samp{z} for MSDOS, OS/2 FAT and Atari.) If no files are specified or
-if a file name is "-", the standard input is compressed to the standard
-output. @code{gzip} will only attempt to compress regular files. In
-particular, it will ignore symbolic links.
-
-If the new file name is too long for its file system, @code{gzip}
-truncates it. @code{gzip} attempts to truncate only the parts of the
-file name longer than 3 characters. (A part is delimited by dots.) If
-the name consists of small parts only, the longest parts are truncated.
-For example, if file names are limited to 14 characters, gzip.msdos.exe
-is compressed to gzi.msd.exe.gz. Names are not truncated on systems
-which do not have a limit on file name length.
-
-By default, @code{gzip} keeps the original file name and timestamp in
-the compressed file. These are used when decompressing the file with the
-@samp{-N} option. This is useful when the compressed file name was
-truncated or when the time stamp was not preserved after a file
-transfer.
-
-Compressed files can be restored to their original form using @samp{gzip -d}
-or @code{gunzip} or @code{zcat}. If the original name saved in the
-compressed file is not suitable for its file system, a new name is
-constructed from the original one to make it legal.
-
-@code{gunzip} takes a list of files on its command line and replaces
-each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z},
-@samp{-gz}, @samp{-z} or @samp{_z} and which begins with the correct
-magic number with an uncompressed file without the original extension.
-@code{gunzip} also recognizes the special extensions @samp{.tgz} and
-@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z}
-respectively. When compressing, @code{gzip} uses the @samp{.tgz}
-extension if necessary instead of truncating a file with a @samp{.tar}
-extension.
-
-@code{gunzip} can currently decompress files created by @code{gzip},
-@code{zip}, @code{compress} or @code{pack}. The detection of the input
-format is automatic. When using the first two formats, @code{gunzip}
-checks a 32 bit CRC (cyclic redundancy check). For @code{pack},
-@code{gunzip} checks the uncompressed length. The @code{compress} format
-was not designed to allow consistency checks. However @code{gunzip} is
-sometimes able to detect a bad @samp{.Z} file. If you get an error when
-uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is
-correct simply because the standard @code{uncompress} does not complain.
-This generally means that the standard @code{uncompress} does not check
-its input, and happily generates garbage output. The SCO @samp{compress
--H} format (@code{lzh} compression method) does not include a CRC but
-also allows some consistency checks.
-
-Files created by @code{zip} can be uncompressed by @code{gzip} only if
-they have a single member compressed with the 'deflation' method. This
-feature is only intended to help conversion of @code{tar.zip} files to
-the @code{tar.gz} format. To extract @code{zip} files with several
-members, use @code{unzip} instead of @code{gunzip}.
-
-@code{zcat} is identical to @samp{gunzip -c}. @code{zcat}
-uncompresses either a list of files on the command line or its standard
-input and writes the uncompressed data on standard output. @code{zcat}
-will uncompress files that have the correct magic number whether they
-have a @samp{.gz} suffix or not.
-
-@code{gzip} uses the Lempel-Ziv algorithm used in @code{zip} and PKZIP.
-The amount of compression obtained depends on the size of the input and
-the distribution of common substrings. Typically, text such as source
-code or English is reduced by 60-70%. Compression is generally much
-better than that achieved by LZW (as used in @code{compress}), Huffman
-coding (as used in @code{pack}), or adaptive Huffman coding
-(@code{compact}).
-
-Compression is always performed, even if the compressed file is slightly
-larger than the original. The worst case expansion is a few bytes for
-the @code{gzip} file header, plus 5 bytes every 32K block, or an expansion
-ratio of 0.015% for large files. Note that the actual number of used
-disk blocks almost never increases. @code{gzip} preserves the mode,
-ownership and timestamps of files when compressing or decompressing.
-
-@node Sample, Invoking gzip, Overview, Top
-@chapter Sample Output
-@cindex sample
-
-Here are some realistic examples of running @code{gzip}.
-
-This is the output of the command @samp{gzip -h}:
-
-@example
-gzip 1.2.4 (18 Aug 93)
-usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
- -c --stdout write on standard output, keep original files unchanged
- -d --decompress decompress
- -f --force force overwrite of output file and compress links
- -h --help give this help
- -l --list list compressed file contents
- -L --license display software license
- -n --no-name do not save or restore the original name and time stamp
- -N --name save or restore the original name and time stamp
- -q --quiet suppress all warnings
- -r --recursive operate recursively on directories
- -S .suf --suffix .suf use suffix .suf on compressed files
- -t --test test compressed file integrity
- -v --verbose verbose mode
- -V --version display version number
- -1 --fast compress faster
- -9 --best compress better
- file... files to (de)compress. If none given, use standard input.
-@end example
-
-This is the output of the command @samp{gzip -v texinfo.tex}:
-
-@example
-texinfo.tex: 71.6% -- replaced with texinfo.tex.gz
-@end example
-
-The following command will find all @code{gzip} files in the current
-directory and subdirectories, and extract them in place without
-destroying the original:
-
-@example
-find . -name '*.gz' -print | sed 's/^\(.*\)[.]gz$/gunzip < "&" > "\1"/' | sh
-@end example
-
-@node Invoking gzip, Advanced usage, Sample, Top
-@chapter Invoking @code{gzip}
-@cindex invoking
-@cindex options
-
-The format for running the @code{gzip} program is:
-
-@example
-gzip @var{option} @dots{}
-@end example
-
-@code{gzip} supports the following options:
-
-@table @samp
-@item --stdout
-@itemx --to-stdout
-@itemx -c
-Write output on standard output; keep original files unchanged.
-If there are several input files, the output consists of a sequence of
-independently compressed members. To obtain better compression,
-concatenate all input files before compressing them.
-
-@item --decompress
-@itemx --uncompress
-@itemx -d
-Decompress.
-
-@item --force
-@itemx -f
-Force compression or decompression even if the file has multiple links
-or the corresponding file already exists, or if the compressed data
-is read from or written to a terminal. If the input data is not in
-a format recognized by @code{gzip}, and if the option @samp{--stdout} is also
-given, copy the input data without change to the standard output: let
-@code{zcat} behave as @code{cat}. If @samp{-f} is not given, and
-when not running in the background, @code{gzip} prompts to verify
-whether an existing file should be overwritten.
-
-@item --help
-@itemx -h
-Print an informative help message describing the options then quit.
-
-@item --list
-@itemx -l
-For each compressed file, list the following fields:
-
-@example
-compressed size: size of the compressed file
-uncompressed size: size of the uncompressed file
-ratio: compression ratio (0.0% if unknown)
-uncompressed_name: name of the uncompressed file
-@end example
-
-The uncompressed size is given as @samp{-1} for files not in @code{gzip}
-format, such as compressed @samp{.Z} files. To get the uncompressed size for
-such a file, you can use:
-
-@example
-zcat file.Z | wc -c
-@end example
-
-In combination with the @samp{--verbose} option, the following fields are also
-displayed:
-
-@example
-method: compression method (deflate,compress,lzh,pack)
-crc: the 32-bit CRC of the uncompressed data
-date & time: time stamp for the uncompressed file
-@end example
-
-The crc is given as ffffffff for a file not in gzip format.
-
-With @samp{--verbose}, the size totals and compression ratio for all files
-is also displayed, unless some sizes are unknown. With @samp{--quiet},
-the title and totals lines are not displayed.
-
-@item --license
-@itemx -L
-Display the @code{gzip} license then quit.
-
-@item --no-name
-@itemx -n
-When compressing, do not save the original file name and time stamp by
-default. (The original name is always saved if the name had to be
-truncated.) When decompressing, do not restore the original file name
-if present (remove only the @code{gzip}
-suffix from the compressed file name) and do not restore the original
-time stamp if present (copy it from the compressed file). This option
-is the default when decompressing.
-
-@item --name
-@itemx -N
-When compressing, always save the original file name and time stamp; this
-is the default. When decompressing, restore the original file name and
-time stamp if present. This option is useful on systems which have
-a limit on file name length or when the time stamp has been lost after
-a file transfer.
-
-@item --quiet
-@itemx -q
-Suppress all warning messages.
-
-@item --recursive
-@itemx -r
-Travel the directory structure recursively. If any of the file names
-specified on the command line are directories, @code{gzip} will descend
-into the directory and compress all the files it finds there (or
-decompress them in the case of @code{gunzip}).
-
-@item --suffix @var{suf}
-@itemx -S @var{suf}
-Use suffix @samp{@var{suf}} instead of @samp{.gz}. Any suffix can be
-given, but suffixes other than @samp{.z} and @samp{.gz} should be
-avoided to avoid confusion when files are transferred to other systems.
-A null suffix forces gunzip to try decompression on all given files
-regardless of suffix, as in:
-
-@example
-gunzip -S "" * (*.* for MSDOS)
-@end example
-
-Previous versions of gzip used the @samp{.z} suffix. This was changed to
-avoid a conflict with @code{pack}.
-
-@item --test
-@itemx -t
-Test. Check the compressed file integrity.
-
-@item --verbose
-@itemx -v
-Verbose. Display the name and percentage reduction for each file compressed.
-
-@item --version
-@itemx -V
-Version. Display the version number and compilation options, then quit.
-
-@item --fast
-@itemx --best
-@itemx -@var{n}
-Regulate the speed of compression using the specified digit @var{n},
-where @samp{-1} or @samp{--fast} indicates the fastest compression
-method (less compression) and @samp{--best} or @samp{-9} indicates the
-slowest compression method (optimal compression). The default
-compression level is @samp{-6} (that is, biased towards high compression at
-expense of speed).
-@end table
-
-@node Advanced usage, Environment, Invoking gzip, Top
-@chapter Advanced usage
-@cindex concatenated files
-
-Multiple compressed files can be concatenated. In this case,
-@code{gunzip} will extract all members at once. If one member is
-damaged, other members might still be recovered after removal of the
-damaged member. Better compression can be usually obtained if all
-members are decompressed and then recompressed in a single step.
-
-This is an example of concatenating @code{gzip} files:
-
-@example
-gzip -c file1 > foo.gz
-gzip -c file2 >> foo.gz
-@end example
-
-Then
-
-@example
-gunzip -c foo
-@end example
-
-is equivalent to
-
-@example
-cat file1 file2
-@end example
-
-In case of damage to one member of a @samp{.gz} file, other members can
-still be recovered (if the damaged member is removed). However,
-you can get better compression by compressing all members at once:
-
-@example
-cat file1 file2 | gzip > foo.gz
-@end example
-
-compresses better than
-
-@example
-gzip -c file1 file2 > foo.gz
-@end example
-
-If you want to recompress concatenated files to get better compression, do:
-
-@example
-zcat old.gz | gzip > new.gz
-@end example
-
-If a compressed file consists of several members, the uncompressed
-size and CRC reported by the @samp{--list} option applies to the last member
-only. If you need the uncompressed size for all members, you can use:
-
-@example
-zcat file.gz | wc -c
-@end example
-
-If you wish to create a single archive file with multiple members so
-that members can later be extracted independently, use an archiver such
-as @code{tar} or @code{zip}. GNU @code{tar} supports the @samp{-z}
-option to invoke @code{gzip} transparently. @code{gzip} is designed as a
-complement to @code{tar}, not as a replacement.
-
-@node Environment, Tapes, Advanced usage, Top
-@chapter Environment
-@cindex Environment
-
-The environment variable @code{GZIP} can hold a set of default options for
-@code{gzip}. These options are interpreted first and can be overwritten by
-explicit command line parameters. For example:
-
-@example
-for sh: GZIP="-8v --name"; export GZIP
-for csh: setenv GZIP "-8v --name"
-for MSDOS: set GZIP=-8v --name
-@end example
-
-On Vax/VMS, the name of the environment variable is @code{GZIP_OPT}, to
-avoid a conflict with the symbol set for invocation of the program.
-
-@node Tapes, Problems, Environment, Top
-@chapter Using @code{gzip} on tapes
-@cindex tapes
-
-When writing compressed data to a tape, it is generally necessary to pad
-the output with zeroes up to a block boundary. When the data is read and
-the whole block is passed to @code{gunzip} for decompression,
-@code{gunzip} detects that there is extra trailing garbage after the
-compressed data and emits a warning by default. You have to use the
-@samp{--quiet} option to suppress the warning. This option can be set in the
-@code{GZIP} environment variable, as in:
-
-@example
-for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
-for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0)
-@end example
-
-In the above example, @code{gzip} is invoked implicitly by the @samp{-z}
-option of GNU @code{tar}. Make sure that the same block size (@samp{-b}
-option of @code{tar}) is used for reading and writing compressed data on
-tapes. (This example assumes you are using the GNU version of
-@code{tar}.)

-@node Problems, Concept Index, Tapes, Top
-@chapter Reporting Bugs
-@cindex bugs

-If you find a bug in @code{gzip}, please send electronic mail to
-@w{@samp{bug-gzip@@gnu.org}}. Include the version number,
-which you can find by running @w{@samp{gzip -V}}. Also include in your

-
-<P>
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
-
-<P>
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-
-<P>
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-
-<P>
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
-
-<P>
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-
-<P>
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-
-<P>
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-
-<P>
- The precise terms and conditions for copying, distribution and
-modification follow.
-
-
-<P>
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-
-
-<OL>
-<LI>
-
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-<LI>
-
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-<LI>
-
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-
-<OL>
-<LI>
-
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-<LI>
-
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-<LI>
-
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-</OL>
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-<LI>
-
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-
-<OL>
-<LI>
-
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-<LI>
-
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-<LI>
-
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-</OL>
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-<LI>
-
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-<LI>
-
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-<LI>
-
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-<LI>
-
-If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-<LI>
-
-If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-<LI>
-
-The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-<LI>
-
-If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-NO WARRANTY
-
-<LI>
-
-BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-<LI>
-
-IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

-
-<P>
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-
-<P>
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.

-If the new file name is too long for its file system, <CODE>gzip</CODE>
-truncates it. <CODE>gzip</CODE> attempts to truncate only the parts of the
-file name longer than 3 characters. (A part is delimited by dots.) If
-the name consists of small parts only, the longest parts are truncated.
-For example, if file names are limited to 14 characters, gzip.msdos.exe
-is compressed to gzi.msd.exe.gz. Names are not truncated on systems
-which do not have a limit on file name length.
-
-
-<P>
-By default, <CODE>gzip</CODE> keeps the original file name and timestamp in
-the compressed file. These are used when decompressing the file with the
-<SAMP>`-N'</SAMP> option. This is useful when the compressed file name was
-truncated or when the time stamp was not preserved after a file
-transfer.
-
-
-<P>
-Compressed files can be restored to their original form using <SAMP>`gzip -d'</SAMP>
-or <CODE>gunzip</CODE> or <CODE>zcat</CODE>. If the original name saved in the
-compressed file is not suitable for its file system, a new name is
-constructed from the original one to make it legal.
-
-
-<P>
-<CODE>gunzip</CODE> takes a list of files on its command line and replaces
-each file whose name ends with <SAMP>`.gz'</SAMP>, <SAMP>`.z'</SAMP>, <SAMP>`.Z'</SAMP>,
-<SAMP>`-gz'</SAMP>, <SAMP>`-z'</SAMP> or <SAMP>`_z'</SAMP> and which begins with the correct
-magic number with an uncompressed file without the original extension.
-<CODE>gunzip</CODE> also recognizes the special extensions <SAMP>`.tgz'</SAMP> and
-<SAMP>`.taz'</SAMP> as shorthands for <SAMP>`.tar.gz'</SAMP> and <SAMP>`.tar.Z'</SAMP>
-respectively. When compressing, <CODE>gzip</CODE> uses the <SAMP>`.tgz'</SAMP>
-extension if necessary instead of truncating a file with a <SAMP>`.tar'</SAMP>
-extension.
-
-
-<P>
-<CODE>gunzip</CODE> can currently decompress files created by <CODE>gzip</CODE>,
-<CODE>zip</CODE>, <CODE>compress</CODE> or <CODE>pack</CODE>. The detection of the input
-format is automatic. When using the first two formats, <CODE>gunzip</CODE>
-checks a 32 bit CRC (cyclic redundancy check). For <CODE>pack</CODE>,
-<CODE>gunzip</CODE> checks the uncompressed length. The <CODE>compress</CODE> format
-was not designed to allow consistency checks. However <CODE>gunzip</CODE> is
-sometimes able to detect a bad <SAMP>`.Z'</SAMP> file. If you get an error when
-uncompressing a <SAMP>`.Z'</SAMP> file, do not assume that the <SAMP>`.Z'</SAMP> file is
-correct simply because the standard <CODE>uncompress</CODE> does not complain.
-This generally means that the standard <CODE>uncompress</CODE> does not check
-its input, and happily generates garbage output. The SCO <SAMP>`compress
--H'</SAMP> format (<CODE>lzh</CODE> compression method) does not include a CRC but
-also allows some consistency checks.
-
-
-<P>
-Files created by <CODE>zip</CODE> can be uncompressed by <CODE>gzip</CODE> only if
-they have a single member compressed with the 'deflation' method. This
-feature is only intended to help conversion of <CODE>tar.zip</CODE> files to
-the <CODE>tar.gz</CODE> format. To extract <CODE>zip</CODE> files with several
-members, use <CODE>unzip</CODE> instead of <CODE>gunzip</CODE>.
-
-
-<P>
-<CODE>zcat</CODE> is identical to <SAMP>`gunzip -c'</SAMP>. <CODE>zcat</CODE>
-uncompresses either a list of files on the command line or its standard
-input and writes the uncompressed data on standard output. <CODE>zcat</CODE>
-will uncompress files that have the correct magic number whether they
-have a <SAMP>`.gz'</SAMP> suffix or not.
-
-
-<P>
-<CODE>gzip</CODE> uses the Lempel-Ziv algorithm used in <CODE>zip</CODE> and PKZIP.
-The amount of compression obtained depends on the size of the input and
-the distribution of common substrings. Typically, text such as source
-code or English is reduced by 60-70%. Compression is generally much
-better than that achieved by LZW (as used in <CODE>compress</CODE>), Huffman
-coding (as used in <CODE>pack</CODE>), or adaptive Huffman coding
-(<CODE>compact</CODE>).
-
-
-<P>
-Compression is always performed, even if the compressed file is slightly
-larger than the original. The worst case expansion is a few bytes for
-the <CODE>gzip</CODE> file header, plus 5 bytes every 32K block, or an expansion
-ratio of 0.015% for large files. Note that the actual number of used
-disk blocks almost never increases. <CODE>gzip</CODE> preserves the mode,
-ownership and timestamps of files when compressing or decompressing.

-Multiple compressed files can be concatenated. In this case,

- Inflate deflated (PKZIP's method 8 compressed) data. The compression
- method searches for as much of the current string of bytes (up to a
- length of 258) in the previous 32K bytes. If it doesn't find any
- matches (of at least length 3), it codes the next byte. Otherwise, it
- codes the length of the matched string and its distance backwards from
- the current position. There is a single Huffman code that codes both
- single bytes (called "literals") and match lengths. A second Huffman
- code codes the distance information, which follows a length code. Each
- length or distance code actually represents a base value and a number
- of "extra" (sometimes zero) bits to get to add to the base value. At
- the end of each deflated block is a special end-of-block (EOB) literal/
- length code. The decoding process is basically: get a literal/length
- code; if EOB then done; if a literal, emit the decoded byte; if a
- length then get the distance and emit the referred-to bytes from the
- sliding window of previously emitted data.
-
- There are (currently) three kinds of inflate blocks: stored, fixed, and
- dynamic. The compressor deals with some chunk of data at a time, and
- decides which method to use on a chunk-by-chunk basis. A chunk might
- typically be 32K or 64K. If the chunk is uncompressible, then the
- "stored" method is used. In this case, the bytes are simply stored as
- is, eight bits per byte, with none of the above coding. The bytes are
- preceded by a count, since there is no longer an EOB code.
-
- If the data is compressible, then either the fixed or dynamic methods
- are used. In the dynamic method, the compressed data is preceded by
- an encoding of the literal/length and distance Huffman codes that are
- to be used to decode this block. The representation is itself Huffman
- coded, and so is preceded by a description of that code. These code
- descriptions take up a little space, and so for small blocks, there is
- a predefined set of codes, called the fixed codes. The fixed method is
- used if the block codes up smaller that way (usually for quite small
- chunks), otherwise the dynamic method is used. In the latter case, the
- codes are customized to the probabilities in the current block, and so
- can code it much better than the pre-determined fixed codes.
-
- The Huffman codes themselves are decoded using a mutli-level table
- lookup, in order to maximize the speed of decoding plus the speed of
- building the decoding tables. See the comments below that precede the
- lbits and dbits tuning parameters.
- */
-
-
-/*
- Notes beyond the 1.93a appnote.txt:
-
- 1. Distance pointers never point before the beginning of the output
- stream.
- 2. Distance pointers can point back across blocks, up to 32k away.
- 3. There is an implied maximum of 7 bits for the bit length table and
- 15 bits for the actual data.
- 4. If only one code exists, then it is encoded using one bit. (Zero
- would be more efficient, but perhaps a little confusing.) If two
- codes exist, they are coded using one bit each (0 and 1).
- 5. There is no way of sending zero distance codes--a dummy must be
- sent if there are none. (History: a pre 2.0 version of PKZIP would
- store blocks with no distance codes, but this was discovered to be
- too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
- zero distance codes, which is sent as one code of zero bits in
- length.
- 6. There are up to 286 literal/length codes. Code 256 represents the
- end-of-block. Note however that the static length tree defines
- 288 codes just to fill out the Huffman codes. Codes 286 and 287
- cannot be used though, since there is no length base or extra bits
- defined for them. Similarly, there are up to 30 distance codes.
- However, static trees define 32 codes (all 5 bits) to fill out the
- Huffman codes, but the last two had better not show up in the data.
- 7. Unzip can check dynamic Huffman blocks for complete code sets.
- The exception is that a single code would not be complete (see #4).
- 8. The five bits following the block type is really the number of
- literal codes sent minus 257.
- 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
- (1+6+6). Therefore, to output three times the length, you output
- three codes (1+1+1), whereas to output four times the same length,
- you only need two codes (1+3). Hmm.
- 10. In the tree reconstruction algorithm, Code = Code + Increment
- only if BitLength(i) is not zero. (Pretty obvious.)
- 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
- 12. Note: length code 284 can represent 227-258, but length code 285
- really is 258. The last length deserves its own, short code
- since it gets used a lot in very redundant files. The length
- 258 is special since 258 - 3 (the min match length) is 255.
- 13. The literal/length and distance code bit lengths are read as a
- single stream of lengths. It is possible (and advantageous) for
- a repeat code (16, 17, or 18) to go across the boundary between
- the two sets of lengths.

- where NEEDBITS makes sure that b has at least j bits in it, and
- DUMPBITS removes the bits from b. The macros use the variable k

- routine that uses these macros from a global bit buffer and count.
-
- If we assume that EOB will be the longest code, then we will never
- ask for bits with NEEDBITS that are beyond the end of the stream.
- So, NEEDBITS should not read any more bytes than are needed to
- meet the request. Then no bytes need to be "returned" to the buffer
- at the end of the last block.
-
- However, this assumption is not true for fixed blocks--the EOB code
- is 7 bits, but the other literal/length codes can be 8 or 9 bits.
- (The EOB code is shorter than other codes because fixed blocks are
- generally short. So, while a block always has an EOB, many other
- literal/length codes have a significantly lower probability of
- showing up at all.) However, by making the first table have a
- lookup of seven bits, the EOB code will be found in that first
- lookup, and so will not require that too many bits be pulled from

- Huffman code decoding is performed using a multi-level table lookup.
- The fastest way to decode is to simply build a lookup table whose
- size is determined by the longest code. However, the time it takes
- to build this table can also be a factor if the data being decoded
- is not very long. The most common codes are necessarily the
- shortest codes, so those codes dominate the decoding time, and hence
- the speed. The idea is you can have a shorter table that decodes the
- shorter, more probable codes, and then point to subsidiary tables for
- the longer codes. The time it costs to decode the longer codes is
- then traded against the time it takes to make longer tables.
-
- This results of this trade are in the variables lbits and dbits
- below. lbits is the number of bits the first level table for literal/
- length codes can decode in one step, and dbits is the same thing for
- the distance codes. Subsequent tables are also less than or equal to
- those sizes. These values may be adjusted either when all of the
- codes are shorter than that, in which case the longest code length in
- bits is used, or when the shortest code is *longer* than the requested
- table size, in which case the length of the shortest code in bits is
- used.
-
- There are two different values for the two tables, since they code a
- different number of possibilities each. The literal/length table
- codes 286 possible values, or in a flat code, a little over eight
- bits. The distance table codes 30 possible values, or a little less
- than five bits, flat. The optimum values for speed end up being
- about one bit more than those, so lbits is 8+1 and dbits is 5+1.
- The optimum values may differ though from machine to machine, and
- possibly even between compilers. Your mileage may vary.

- Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:

-
- Polynomials over GF(2) are represented in binary, one bit per coefficient,
- with the lowest powers in the most significant bit. Then adding polynomials
- is just exclusive-or, and multiplying a polynomial by x is a right shift by
- one. If we call the above polynomial p, and represent a byte as the
- polynomial q, also with the lowest power in the most significant bit (so the
- byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
- where a mod b means the remainder after dividing a by b.
-
- This calculation is done using the shift-register method of multiplying and
- taking the remainder. The register is initialized to zero, and for each
- incoming bit, x^32 is added mod p to the register if the bit is a one (where
- x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
- x (which is shifting right by one and adding x^32 mod p if the bit shifted
- out is a one). We start with the highest power (least significant bit) of
- q and repeat for all eight bits of q.
-
- The table is simply the CRC of all possible eight bit values. This is all
- the information needed to generate CRC's on data a byte at a time for all
- combinations of CRC register values and incoming bytes. The table is
- written to stdout as 256 long hexadecimal values in C language format.

-/* sub is a simple filter to preprocess a data file before compression.
- It can increase compression for data whose points tend to be close to
- the last point. The output is the difference of successive bytes of
- the input. The add filter is used to undo what sub does. This could
- be used on 8-bit sound or graphics data.
-
- sub can also take an argument to apply this to interleaved sets of
- bytes. For example, if the data are 16-bit sound samples, then you
- can use "sub 2" to take differences on the low-byte stream and the
- high-byte stream. (This gives nearly the same effect as subtracting
- the 16-bit values, but avoids the complexities of endianess of the
- data.) The concept extends to RGB image data (sub 3), 16-bit stereo
- data (sub 4), floating point data (sub 4 or sub 8), etc.
-
- add takes no options, since the number of interleaved byte streams
- is put in the first two bytes of the output stream for add to use
- (in little-endian format).
-
- Examples:
-
- sub < graph.vga | gzip -9 > graph.vga.sgz
- sub < phone.snd | gzip -9 > phone.snd.sgz
- sub 2 < audio.snd | gzip -9 > audio.snd.sgz
- sub 3 < picture.rgb | gzip -9 > picture.rgb.sgz
- sub 4 < stereo.snd | gzip -9 > stereo.snd.sgz
- sub 8 < double.data | gzip -9 > double.data.sgz
-
- To expand, use the reverse operation, as in:
-
- gunzip < double.data.sgz | add > double.data

- * PURPOSE
- *
- * Encode various sets of source values using variable-length
- * binary code trees.
- *
- * DISCUSSION
- *
- * The PKZIP "deflation" process uses several Huffman trees. The more
- * common source values are represented by shorter bit sequences.
- *
- * Each code tree is stored in the ZIP file in a compressed form
- * which is itself a Huffman encoding of the lengths of
- * all the code strings (in ascending order by source values).
- * The actual code strings are reconstructed from the lengths in
- * the UNZIP process, as described in the "application note"
- * (APPNOTE.TXT) distributed as part of PKWARE's PKZIP program.

-README file for gzip on VMS

-GZIP.HLP ! Help-file, how to use gzip
-MAKEFILE.GCC ! Description for (vms-)make, using gcc
-MAKEFILE.MMS ! Description for MMS-utility, using vaxc
-MAKEFILE.VMS ! Description for (vms-)make, using vaxc

-
-This file describe, how to compile and install the VMS-Port of gzip.
->>For restrictions or bugs due to the structure of the vms-filesystem
-refer to gzip.hlp.<<
-
-Installing gzip
-
-Since there are many makefiles there are many possibilities
-compiling and installing gzip. For most of them, it is important,
-that you start them from the SOURCE-Directory (that is where
-gzip.c is), not from the [.vms]-directory. Otherwise the compiler
-won't find the source-files.
-
-Using gcc saves disk-space, but needs longer to compile
- VAXC gzip.exe 95/96 Blocks
- gcc2.3.3 gzip.exe 86/87 Blocks
-
-To install gzip one has to perform the following steps:
- 1. compile sources (*.c, [.vms]*.c)
- 2. link executable gzip.exe
- 3. Make entries gunzip.exe and zcat.exe to gzip.exe.
- These are similar to hardlinks in UNIX
- >>If You wish to do this by hand, see for example makegzip.com.<<
- The Entries can't be simply deleted, use 'set file /remove' .
-
- 4. Rename executables (*.exe) to Your prefered exe-directory. If it is on
- another Device, then you should only copy gzip.exe and do the
- entries gunzip.exe and zcat.exe by hand (3.).
-
- 5. Setting up Symbols for the executables:
- Place the following lines in Your login.com
- Change "disk:[directory]" as appropriate.
- $ gzip == "$disk:[directory]gzip.exe"
- $ gunzip == "$disk:[directory]gunzip.exe"
- $ zcat == "$disk:[directory]zcat.exe"
- 6. insert help-file gzip.hlp in any Help-library,
- for example in sys$help:helplib.
- this can be done by $lib sys$help:helplib/help gzip
- (I did not try this command)
-
-Steps (4.)5. through 6 must be done by hand.
-Steps 1 through 3(4.) may be done by one of the makefiles:
-
-a) MAKEGZIP.COM
-This was crated from MAKEFILE.VMS and later on edited. It uses the
-VAXC-Compiler and does compiling, linking and making the entries.
-Usage:
-- change to the Source-Directory
-- copy vms.c
- $copy [.vms]vms.c []
-- start compiling, linking, entries
- $@[.vms]makegzip
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-continue at Step 4.
-
-b) MAKEFILE.VMS
-Makefile for a vms-make utility (NOT gnu-make).
-Is uses the VAXC-Compiler and has the Advantage over MAKEGZIP.COM
-that make checks dependencies. This is helpfull if You have to
-recompile several times, for example after editing the sources.
-- change to the Source-Directory
-- copy vms.c
- $copy [.vms]vms.c []
-- start compiling, linking, entries
- $make /input=[.vms]makefile.vms
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-Continue at Step 4.
-
-c) MAKEFILE.GCC
-Same as MAKEFILE.VMS, but uses gcc
-- Use $make /input=[.vms]makefile.gcc instead of make ....
-
-d) MAKEFILE.MMS
-Makefile for the MMS-utility. Similar to MAKEFILE.VMS
-- Use $mms /description=[.vms]makefile.mms instead of make ....

-1 GZIP
-NAME
- gzip, gunzip, zcat - compress or expand files
-
-SYNOPSIS
- gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
- gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
- zcat [ -fhLV ] [ name ... ]
-
-2 DESCRIPTION
- Gzip reduces the size of the named files using Lempel-Ziv
- coding (LZ77). Whenever possible, each file is replaced by
- one with the extension .gz, while keeping the same ownership
- modes, access and modification times. (The default exten-
- sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT
- and Atari.) If no files are specified, or if a file name is
- "-", the standard input is compressed to the standard out-
- put. Gzip will only attempt to compress regular files.
-
- If the compressed file name is too long for its file system,
- gzip truncates it. Gzip attempts to truncate only the parts
- of the file name longer than 3 characters. (A part is del-
- imited by dots.) If the name consists of small parts only,
- the longest parts are truncated. For example, if file names
- are limited to 14 characters, gzip.msdos.exe is compressed
- to gzi.msd.exe.gz. Names are not truncated on systems which
- do not have a limit on file name length.
-
- By default, gzip keeps the original file name and timestamp
- in the compressed file. These are used when decompressing
- the file with the -N option. This is useful when the
- compressed file name was truncated or when the time stamp
- was not preserved after a file transfer.
-
- Compressed files can be restored to their original form
- using gzip -d or gunzip or zcat. If the original name saved
- in the compressed file is not suitable for its file system,
- a new name is constructed from the original one to make it
- legal.
-
- gunzip takes a list of files on its command line and
- replaces each file whose name ends with .gz, -gz, .z, -z, _z
- or .Z and which begins with the correct magic number with an
- uncompressed file without the original extension. gunzip
- also recognizes the special extensions .tgz and .taz as
- shorthands for .tar.gz and .tar.Z respectively. When
- compressing, gzip uses the .tgz extension if necessary
- instead of truncating a file with a .tar extension.
-
- gunzip can currently decompress files created by gzip, zip,
- compress, compress -H or pack. The detection of the input
- format is automatic. When using the first two formats,
- gunzip checks a 32 bit CRC. For pack, gunzip checks the
- uncompressed length. The standard compress format was not
- designed to allow consistency checks. However gunzip is
- sometimes able to detect a bad .Z file. 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 out-
- put. The SCO compress -H format (lzh compression method)
- does not include a CRC but also allows some consistency
- checks.
-
- Files created by zip can be uncompressed by gzip only if
- they have a single member compressed with the 'deflation'
- method. This feature is only intended to help conversion of
- tar.zip files to the tar.gz format. To extract zip files
- with several members, use unzip instead of gunzip.
-
- zcat is identical to gunzip -c. (On some systems, zcat may
- be installed as gzcat to preserve the original link to
- compress.) zcat uncompresses either a list of files on the
- command line or its standard input and writes the
- uncompressed data on standard output. zcat will uncompress
- files that have the correct magic number whether they have a
- .gz suffix or not.
-
- Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP.
- The amount of compression obtained depends on the size of
- the input and the distribution of common substrings. Typi-
- cally, text such as source code or English is reduced by
- 60-70%. Compression is generally much better than that
- achieved by LZW (as used in compress), Huffman coding (as
- used in pack), or adaptive Huffman coding (compact).
-
- Compression is always performed, even if the compressed file
- is slightly larger than the original. The worst case expan-
- sion is a few bytes for the gzip file header, plus 5 bytes
- every 32K block, or an expansion ratio of 0.015% for large
- files. Note that the actual number of used disk blocks
- almost never increases. gzip preserves the mode, ownership
- and timestamps of files when compressing or decompressing.
-
-2 OPTIONS
- -a --ascii
- Ascii text mode: convert end-of-lines using local con-
- ventions. This option is supported only on some non-
- Unix systems. For MSDOS, CR LF is converted to LF when
- compressing, and LF is converted to CR LF when
- decompressing.
-
- -c --stdout --to-stdout
- Write output on standard output; keep original files
- unchanged. If there are several input files, the out-
- put consists of a sequence of independently compressed
- members. To obtain better compression, concatenate all
- input files before compressing them.
-
- -d --decompress --uncompress
- Decompress.
-
- -f --force
- Force compression or decompression even if the file has
- multiple links or the corresponding file already
- exists, or if the compressed data is read from or writ-
- ten to a terminal. If the input data is not in a format
- recognized by gzip, and if the option --stdout is also
- given, copy the input data without change to the stan-
- dard ouput: let zcat behave as cat. If -f is not given,
- and when not running in the background, gzip prompts to
- verify whether an existing file should be overwritten.
-
- -h --help
- Display a help screen and quit.
-
- -l --list
- For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
- The uncompressed size is given as -1 on VMS because it
- it is not possible to seek reliably to the end of the
- compressed file, where this size is stored.
-
- In combination with the --verbose option, the following
- fields are also displayed:
-
- method: compression method
- crc: the 32-bit CRC of the uncompressed data
- date & time: time stamp for the uncompressed file
-
- The compression methods currently supported are
- deflate, compress, lzh (SCO compress -H) and pack. The
- crc is given as ffffffff on VMS for the reason given
- above about the uncompressed size.
-
- With --name, the uncompressed name, date and time are
- those stored within the compress file if present.
-
- With --verbose, the size totals and compression ratio
- for all files is also displayed, unless some sizes are
- unknown. With --quiet, the title and totals lines are
- not displayed.
-
- -L --license
- Display the gzip license and quit.
-
- -n --no-name
- When compressing, do not save the original file name
- and time stamp by default. (The original name is always
- saved if the name had to be truncated.) When
- decompressing, do not restore the original file name if
- present (remove only the gzip suffix from the
- compressed file name) and do not restore the original
- time stamp if present (copy it from the compressed
- file). This option is the default when decompressing.
-
- -N --name
- When compressing, always save the original file name
- and time stamp; this is the default. When decompress-
- ing, restore the original file name and time stamp if
- present. This option is useful on systems which have a
- limit on file name length or when the time stamp has
- been lost after a file transfer.
-
- -q --quiet
- Suppress all warnings.
-
- -r --recursive
- Travel the directory structure recursively. If any of
- the file names specified on the command line are direc-
- tories, gzip will descend into the directory and
- compress all the files it finds there (or decompress
- them in the case of gunzip ).
-
- -S suf --suffix suf
- Use suffix suf instead of -gz. Any suffix can be
- given, but suffixes other than -z and -gz should be
- avoided to avoid confusion when files are transferred
- to other. A null suffix forces gunzip to try
- decompression on all given files regardless of suffix,
- as in:
-
- gunzip --suffix "" *.*
-
- Previous versions of gzip used the -z suffix. This was
- changed to avoid a conflict with pack on Unix.
-
- -t --test
- Test. Check the compressed file integrity.
-
- -v --verbose
- Verbose. Display the name and percentage reduction for
- each file compressed or decompressed.
-
- -V --version
- Version. Display the version number and compilation
- options then quit.
-
- -# --fast --best
- Regulate the speed of compression using the specified
- digit #, where -1 or --fast indicates the fastest
- compression method (less compression) and -9 or --best
- indicates the slowest compression method (best compres-
- sion). The default compression level is -6 (that is,
- biased towards high compression at expense of speed).
-
-2 ENVIRONMENT
- The environment variable GZIP_OPT can hold a set of default
- options for gzip. These options are interpreted first and
- can be overwritten by explicit command line parameters. For
- example:
- define GZIP_OPT "-8 -v"
-
-2 SEE ALSO
- compress, zip, unzip
-
-2 DIAGNOSTICS
- Exit status is normally 0; if an error occurs, exit status
- is 1. If a warning occurs, exit status is 2.
-
- Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
- Invalid options were specified on the command line.
- file: not in gzip format
- The file specified to gunzip has not been
- compressed.
- file: Corrupt input. Use zcat to recover some data.
- The compressed file has been damaged. The data up to
- the point of failure can be recovered using
- define /user sys$output file.recover
- zcat file
- file: compressed with xx bits, can only handle yy bits
- File was compressed (using LZW) by a program that
- could deal with more bits than the decompress code
- on this machine. Recompress the file with gzip,
- which compresses better and uses less memory.
- file: already has -gz suffix -- no change
- The file is assumed to be already compressed.
- Rename the file and try again.
- file already exists; do you wish to overwrite (y or n)?
- Respond "y" if you want the output file to be
- replaced; "n" if not.
- gunzip: corrupt input
- A SIGSEGV violation was detected which usually means
- that the input file has been corrupted.
- xx.x%
- Percentage of the input saved by compression.
- (Relevant only for -v and -l.)
- -- not a regular file or directory: ignored
- When the input file is not a regular file or direc-
- tory, it is left unaltered.
-
-2 CAVEATS
- On VMS:
- - upper case options need quotes: gzip "-V".
- - restoration of timestamps and version numbers is not supported
- - If a compressed file already exists, gzip -f overwrites it, it
- does not create a new version.
- - multi-part gzip files are not supported.
- - gunzip does not preserve the input file format. You can use a
- separate utility to restore the original format.
- - gunzip and zcat can be used only if you have created the
- links to gzip as documented in makegzip.com. Otherwise
- you must use explicit parameters ("gzip -c" or "gzip -dc").
- - gzip --list cannot give the uncompressed size and crc.
-
- When writing compressed data to a tape, it is generally
- necessary to pad the output with zeroes up to a block boun-
- dary. When the data is read and the whole block is passed to
- gunzip for decompression, gunzip detects that there is extra
- trailing garbage after the compressed data and emits a warn-
- ing by default. You have to use the --quiet option to
- suppress the warning. This option can be set in the GZIP_OPT
- environment variable as in:
- define GZIP_OPT "-q"
-
-2 BUGS
- On VMS, files in VFC record format are not correctly handled by
- the C runtime library (the linefeed character is suppressed).
-
- In some rare cases, the --best option gives worse compres-
- sion than the default compression level (-6). On some highly
- redundant files, compress compresses better than gzip.

-This can be useful for files with names truncated after a file transfer.
-On systems with a 14 char limitation on file names, the original name

-.TH ZMORE 1
-.SH NAME
-zmore \- file perusal filter for crt viewing of compressed text
-.SH SYNOPSIS
-.B zmore
-[ name ... ]
-.SH DESCRIPTION
-.I Zmore
-is a filter which allows examination of compressed or plain text files
-one screenful at a time on a soft-copy terminal.
-.I zmore
-works on files compressed with
-.I compress, pack
-or
-.I gzip,
-and also on uncompressed files.
-If a file does not exist,
-.I zmore
-looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
-.PP
-.I Zmore
-normally pauses after each screenful, printing --More--
-at the bottom of the screen.
-If the user then types a carriage return, one more line is displayed.
-If the user hits a space,
-another screenful is displayed. Other possibilities are enumerated later.
-.PP
-.I Zmore
-looks in the file
-.I /etc/termcap
-to determine terminal characteristics,
-and to determine the default window size.
-On a terminal capable of displaying 24 lines,
-the default window size is 22 lines.
-To use a pager other than the default
-.I more,
-set environment variable PAGER to the name of the desired program, such as
-.I less.
-.PP
-Other sequences which may be typed when
-.I zmore
-pauses, and their effects, are as follows (\fIi\fP is an optional integer
-argument, defaulting to 1) :
-.PP
-.IP \fIi\|\fP<space>
-display
-.I i
-more lines, (or another screenful if no argument is given)
-.PP
-.IP ^D
-display 11 more lines (a ``scroll'').
-If
-.I i
-is given, then the scroll size is set to \fIi\|\fP.
-.PP
-.IP d
-same as ^D (control-D)
-.PP
-.IP \fIi\|\fPz
-same as typing a space except that \fIi\|\fP, if present, becomes the new
-window size. Note that the window size reverts back to the default at the
-end of the current file.
-.PP
-.IP \fIi\|\fPs
-skip \fIi\|\fP lines and print a screenful of lines
-.PP
-.IP \fIi\|\fPf
-skip \fIi\fP screenfuls and print a screenful of lines
-.PP
-.IP "q or Q"
-quit reading the current file; go on to the next (if any)
-.PP
-.IP "e or q"
-When the prompt --More--(Next file:
-.IR file )
-is printed, this command causes zmore to exit.
-.PP
-.IP s
-When the prompt --More--(Next file:
-.IR file )
-is printed, this command causes zmore to skip the next file and continue.
-.PP
-.IP =
-Display the current line number.
-.PP
-.IP \fIi\|\fP/expr
-search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
-If the pattern is not found,
-.I zmore
-goes on to the next file (if any).
-Otherwise, a screenful is displayed, starting two lines before the place
-where the expression was found.
-The user's erase and kill characters may be used to edit the regular
-expression.
-Erasing back past the first column cancels the search command.
-.PP
-.IP \fIi\|\fPn
-search for the \fIi\|\fP-th occurrence of the last regular expression entered.
-.PP
-.IP !command
-invoke a shell with \fIcommand\|\fP.
-The character `!' in "command" are replaced with the
-previous shell command. The sequence "\\!" is replaced by "!".
-.PP
-.IP ":q or :Q"
-quit reading the current file; go on to the next (if any)
-(same as q or Q).
-.PP
-.IP .
-(dot) repeat the previous command.
-.PP
-The commands take effect immediately, i.e., it is not necessary to
-type a carriage return.
-Up to the time when the command character itself is given,
-the user may hit the line kill character to cancel the numerical
-argument being formed.
-In addition, the user may hit the erase character to redisplay the
---More-- message.
-.PP
-At any time when output is being sent to the terminal, the user can
-hit the quit key (normally control\-\\).
-.I Zmore
-will stop sending output, and will display the usual --More--
-prompt.
-The user may then enter one of the above commands in the normal manner.
-Unfortunately, some output is lost when this is done, due to the
-fact that any characters waiting in the terminal's output queue
-are flushed when the quit signal occurs.
-.PP
-The terminal is set to
-.I noecho
-mode by this program so that the output can be continuous.
-What you type will thus not show on your terminal, except for the / and !
-commands.
-.PP
-If the standard output is not a teletype, then
-.I zmore
-acts just like
-.I zcat,
-except that a header is printed before each file.

-.TH ZNEW 1
-.SH NAME
-znew \- recompress .Z files to .gz files
-.SH SYNOPSIS
-.B znew
-[ -ftv9PK] [ name.Z ... ]
-.SH DESCRIPTION
-.I Znew
-recompresses files from .Z (compress) format to .gz (gzip) format.
-If you want to recompress a file already in gzip format, rename the file
-to force a .Z extension then apply znew.
-.SH OPTIONS
-.TP
-.B \-f
-Force recompression from .Z to .gz format even if a .gz file already exists.
-.TP
-.B \-t
-Tests the new files before deleting originals.
-.TP
-.B \-v
-Verbose. Display the name and percentage reduction for each file compressed.
-.TP
-.B \-9
-Use the slowest compression method (optimal compression).
-.TP
-.B \-P
-Use pipes for the conversion to reduce disk space usage.
-.TP
-.B \-K
-Keep a .Z file when it is smaller than the .gz file
-.SH "SEE ALSO"
-gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1)
-.SH BUGS
-.I Znew
-does not maintain the time stamp with the -P option if
-.I cpmod(1)
-is not available and
-.I touch(1)
-does not support the -r option.
