+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser 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
+
+ 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) <year> <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.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General
+Public License instead of this License.

+ Allow 'force' to override the caution about sticky files.
+ Use the same form for time stamps that treat_stdin uses.
+
+ * zdiff.in: Fix typo that broke most usages. Problem reported by
+ Jari Aalto in <http://bugs.debian.org/404114>. While we're at it,
+ fix a bunch of other problems. Handle "-" better. Send
+ diagnostics to stderr, not stdout. Use expr rather than echo |
+ sed, to handle special characters better. Report a diagnostic in
+ the 1-arg case, if the argument doesn't end in .gz or the like,
+ rather than having incomprehensible behavior. Do not require that
+ the inputs be regular files. Avoid creating a temporary entirely,
+ if /dev/fd works. If not, then resist denial-of-service attacks
+ better, by using mktemp.
+ * NEWS: Document this.

+
+ * inflate.c (huft_build): Fix regression that caused gzip to
+ refuse to uncompress null input (all zero length codes). Problem
+ reported by Yiorgos Adamopoulos. This regression was caused by
+ the security patch installed 2006-11-20, which in turn came from
+ Debian, which in turn apparently came from Thomas Biege of SuSe.
+
+2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS, configure.ac (AC_INIT):
+ Version 1.3.9 released.
+
+ * Makefile.am (MOSTLYCLEANFILES): Add _match.i.
+ * configure.ac (for an assembler syntax supported by this package):
+ Remove _match.i.
+
+ * bootstrap (gnulib_tool_options_extras): New var.
+ (gnulib_tool_options): Use it.
+ * bootstrap.conf (gnulib_tool_options_extras): Avoid getline and
+ rpmatch. gzip doesn't need them, since it doesn't ENABLE_NLS.
+
+2006-12-13 Bruno Haible <bruno@clisp.org>

+
+ The SSIZE_MAX fix didn't work on NSK, so fix it in a more-reliable

+ up on the SEDCMD fix of 2006-12-01.
+ * zforce.in: Likewise.

+
+ * NEWS: Document the fixes below.
+ * configure.ac (AC_CHECK_FUNCS_ONCE): Add siginterrupt.
+ * gzip.c (lstat) [!defined(HAVE_LSTAT) && !defined(lstat)]: Remove.
+ (SA_NOCLDSTOP, sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
+ New macros.
+ (siginterrupt) [!defined SA_NOCLDSTOP && ! HAVE_SIGINTERRUPT]:
+ New macro.
+ (HAVE_WORKING_O_NOFOLLOW): Define to 0 if not defined.
+ (caught_signals, exiting_signal, remove_ofname_fd): New vars.
+ (remove_ofname): Remove; all uses changed to remove_ofname_fd.
+ (same_file, name_too_long): Remove.
+ (install_signal_handlers): New function. It prefers sigaction,
+ which is more reliable in the presence of race conditions.
+ Catch SIGXCPU and SIGXFSZ, too.
+ (main): Use it instead of installing them by hand.
+ (treat_file): Check for read error when closing ifd.
+ (treat_file, create_outfile, remove_output_file):
+ Avoid race conditions with signals.
+ (create_outfile, check_ofname): Remove most of the gorp about
+ working around ENAMETOOLONG deficiencies. It's obsolete now, and
+ anyway it had race conditions. Just rely on O_EXCL and
+ ENAMETOOLONG. The worst that can happen is that a file name will
+ be silently truncated on an obsolete machine, but no data will be lost.
+ (open_and_stat): Use HAVE_WORKING_O_NOFOLLOW rather than O_NOFOLLOW
+ to work around some O_NOFOLLOW bugs. Otherwise, fall back on
+ lstat only if lstat is available, as symlinks don't exist otherwise.
+ (open_input_file): Use O_NONBLOCK and O_NOCTTY too, to avoid
+ hanging gzip on special files.
+ (abort_gzip_signal): If sigaction is not available, ignore
+ signals. If we get the exiting signal, exit with ERROR status
+ rather than raising a signal.
+ * tailor.h (NO_ST_INO): Remove; no longer used now that same_file
+ is gone.
+
+2006-12-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ Port to Tandem NSK/OSS, which lacks fchdir. Problem reported by
+ Matthew Woehlke in
+ <http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
+ * bootstrap.conf (gnulib_modules): Remove openat, as it pulls in
+ fchdir.
+ * configure.ac: Check for fdopendir.
+ * gzip.c: Don't include openat.h; no longer needed.
+ (treat_dir) [!HAVE_FDOPENDIR]: Fall back on the old opendir method
+ since fdopendir is not available.
+
+2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Describe the following change briefly.
+ * bootstrap.conf (gnulib_modules): Remove stat-macros; no longer
+ needed.
+ * gzip.c: Don't include stat-macros.h; no longer needed.
+ (treat_file): Refuse to compress files that are setuid, or setgid,
+ as this can in theory lead to security holes. Also, refuse to
+ compress files with the sticky bit set, on general principle.
+ (copy_stat): Don't copy the setuid, setgid, or sticky bits,
+ as (given the above change) they'll always be zero here.
+ Invoke chmod before chown, to close a race condition.
+
+ * .cvsignore: Add *.doc, build-aux.
+ * doc/.cvignore: New file.
+ * lib/.cvsignore: New file.
+ * m4/.cvsignore: New file.
+
+2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/gzip.texi (Overview): Mention limits of gzip format's
+ time stamps. Also, gzip doesn't always preserve time stamps.
+
+ * gzip.c (abort_gzip_signal): Don't call abort () as a "safeguard",
+ since it actually causes a core dump. Problem reported by
+ Jakub Bogusz.
+
+ * NEWS: Describe gzexe changes noted below.
+ * Makefile.am (.in): Don't bother with SEDCMD. This stuff isn't needed
+ any more (the hosts it caters to are long extinct), and was
+ questionable anyway since the code assumes the skip= line was line 2.
+ * configure.ac (AC_SYS_INTERPRETER, SEDCMD): Remove; no longer needed.
+
+ * gzexe.in: Sweep the code and fix some bugs.
+ My, what sharp teeth you have, gzexe!
+ The straw that broke this camel's back was Matthew Burgess's bug report
+ <http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00012.html>.
+
+ (IFS): Set it to the standard value, both here and in the
+ script gzexe generates.
+ Check for missing operand after parsing options, not before.
+ This fixes the case for "cpexe --".
+ Check for tail -n problem separately in gzexe and in the executable
+ it generates, in case it's a different 'tail'.
+ (trap): Remove $tmp only if $tmp is not the empty string.
+ Preserve exit status.
+ Don't use the nonstandard (and rarely available) "cpmod" utility.
+ Don't use "set -C"; it's no longer useful and it breaks things
+ in some cases.
+ (main loop): Handle file names beginning with "-".
+ Exit with status of failing program, not with 1.
+ Fix some bugs in printing diagnostics, and in quoting.
+ Require the skip= line to have at least one digit.
+ Use test -u and test -g rather than using the (less-reliable) ls.
+ Refuse to compress more programs, e.g., sh.
+ Use mktemp rather than tempfile. Build a copy of
+ the compressed or uncompressed executable in the same
+ directory as the executable, as that's less likely to go wrong
+ if disk space is low. Have the executable exit with status 127,
+ not 1, if the decompression process fails; this is more compatible
+ with meta-programs like nohup. Have the executable
+ uncompress to a temp file with the same basename as the executable;
+ this is more likely to go right. Fix a race condition where the
+ executable temporarily did not exist (in either old or new forms).
+ Check for race conditions better when mv fails. Do not attempt
+ to use cp to do the real work, only to copy permissions to a temp
+ file, since we don't want to trash running executables.
+
+2006-11-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * inflate.c (inflate_dynamic, inflate): Don't send output to
+ stderr unless DEBUG is defined and 'verbose'. Problem reported by
+ Santiago Vila.
+
+ * zgrep.in: If the file name contains newline, &, \, or |, escape
+ the character so that 'sed' doesn't mishandle it as a replacement.
+ Problem reported by Bdale Garbee.
+
+2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * gzip.1 (OPTIONS): ouput -> output. Problem reported by Matt
+ Taggart.
+ * vms/gzip.hlp: Likewise.
+
+ * Makefile.am (FILES_TO_CHECK): New macro.
+ (check-local): Check only the files in FILES_TO_CHECK, since some
+ files under the working directory might be mutating as the test is
+ run, e.g., with "make check >log". Problem reported by Jim
+ Meyering.

+ (DIR_OPT, TIME_OPT): Remove.
+ (_D_EXACT_NAMLEN): Renamed from NAMLEN. All uses changed.
+ (S_ISDIR, S_ISREG, O_BINARY, O_CREAT, O_EXCL, S_IRUSR, S_IWUSR):
+ Remove; gnulib now does this.
+ (RETSIGTYPE): Remove; Autoconf does this.
+ (program_name): Renamed from progname, for compatibility with gnulib.
+ All uses changed.
+ (time_stamp): Now struct timespec, not time_t. All uses changd.
+ (remove_oftime): Now volatile.
+ (reset_times): Remove; now done by futimens.
+ (usage): Remove.
+ (try_help): New function.
+ (help, license): Don't output date as part of version.
+ A version number suffices.
+ (help): Redo help message to match style of coreutils etc.
+ (version): Don't bother printing compile-time configuration info
+ like STDC_HEADERS.
+ (main): Don't assume strlen (argv[0]) < INT_MAX (!).

+ functions.
+ (make_ofname): Don't use WARN, as it affects exit status.
+ (get_method): When the original file name was truncated,
+ restore from its base name, not from its full name.
+ (do_list): Avoid undefined behavior with out-of-range time stamps.
+ ctime, for example, cannot be invoked on arbitrary time stamps safely,
+ since it might overrun an internal buffer. Do not assume that
+ localtime succeeds.
+ (copy_stat): Do not remove input file; that's now the caller's
+ responsibility. This avoids a problem if there is a write error
+ when the caller closes the output file.

+ leaves while reading it. Fix off-by-one error in final check.
+ * util.c: Include <xalloc.h>, for xalloc_die decl.
+ (gzip_base_name): Renamed from base_name, so we don't collide
+ with gnulib. All uses changed.

+ All uses changed.

+ (check-local): New rule.
+ (MOSTLYCLEANFILES): Add _match.S.

+
+2002-09-28 Paul Eggert <eggert@twinsun.com>
+
+ * zforce.in: Use shell pattern matching instead of 'expr', which
+ mishandles names like "+". Remove old check for 14-byte file
+ names on hosts with broken "mv" implementations, as such systems
+ aren't in use any more and it's better nowadays to support file
+ names longer than 14 bytes. Rely on "mv"'s error-reporting.
+ This fixes a portability bug reported by Ralf Neubauer, along
+ with some other bugs.
+
+ Remove dangling output symlinks properly.
+ Bug reported by Kalle Olavi Niemitalo.
+ * gzip.c (lstat): New macro, for platforms lacking lstat.
+ (do_stat): Use it.
+ (name_too_long, check_ofname): Use lstat instead of stat.
+
+2002-09-27 Paul Eggert <eggert@twinsun.com>
+
+ * zforce.in: Use "gzip -lv", not "gzip -v". Patch by Ralf
+ Neubauer.
+
+ * configure.in (ASCPP): Don't use test -a, as POSIX says it's
+ not portable.
+ * znew.in: Likewise.
+ * zmore.in: Likewise. Similarly, don't use test -o, or test -t
+ with no operand.
+
+ * gzexe.in (PATH): Set to same as other programs.
+ Don't assume "tail +22" works; POSIX removed this.
+ Check against compressing "tail".

+ by Autoconf.
+ (AC_SUBST): Remove CFLAGS; now done by Autoconf.
+
+ * gzip.texi: Use the GNU FDL for distribution terms, following the
+ recipe in the Texinfo manual. Use Automake-generated variables
+ for date and version.

+ * Makefile.am (AM_MAKEINFOFLAGS): Add --no-split.
+ (gzip_TEXINFOS): New macro.
+
+ * tailor.h (NO_DIR): Define to 1, not the empty string.
+ * gzip.c (NO_DIR): Define to 0 if not defined. All uses changed.
+ (usage): Don't put '#if' inside printf, as the C standard says
+ that it is not portable if printf is a macro.
+
+ Don't lose output when decompressing truncated input.
+ Bug reported by Nadav Har'El.
+ * inflate.c (GETBYTE): New macro.
+ (NEXTBYTE): Use it.
+ (inflate_dynamic, inflate_block): Add a local variable w, needed
+ by GETBYTE.
+
+2002-03-08 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, README, revision.h, gzip.texi,
+ configure.in (AM_INIT_AUTOMAKE): Revision 1.3.3, dated today.
+
+ * README-alpha: Now using latest stable GNU tools.
+ Using the latest tools allows gzip to build correctly on hosts
+ conforming to POSIX 1003.1-2001.
+
+ * configure.in (match): Use AC_LIBOBJ; Autoconf 2.53 requires it.
+ (LIBOBJS): No longer need to subst, since AC_LIBOBJ does it.
+ (AC_PREREQ): Bump to 2.53.
+
+ * Makefile.am (install-exec-hook, remove-installed-links):
+ Work even when configured with --program-transform-name.
+
+ * gzip.c (license_msg): Update copyright.

+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+Major changes in Gzip 1.3.12 (2007-04-13)
+
+* znew now uses $TMPDIR (default /tmp) instead of always using /tmp.
+
+Major changes in Gzip 1.3.11 (2007-02-05)
+
+* As per the GNU coding standards, the behavior of gzip and its
+ companion executables no longer depend on the name used to invoke them.
+ For example, 'gzip' and 'gunzip' are no longer hard links;
+ instead, 'gunzip' is now a small program that invokes 'gzip -d'.
+
+* zdiff now checks for subsidiary gzip failures, and works around
+ bugs in IRIX 6 sh, Tru64 4.0F ksh, and Solaris 8 bash.
+
+Major changes in Gzip 1.3.10 (2006-12-30)
+
+* gzip -c and zcat now work on special files, files with special mode bits,
+ and files with multiple hard links.
+* gzip -q now exits with status 2 (not 1) when SIGPIPE is received.
+* zcmp and zdiff did not work in the usual case, due to a typo.
+* zgrep has many bugs fixed with argument handling, special characters,
+ and exit status.
+* zless no longer mishandles $%=~ in file names.
+
+Gzip 1.3.9 (2006-12-15)
+
+* No major changes; only porting fixes.
+
+Major changes in Gzip 1.3.8 (2006-12-08)
+
+* Fix some gzip problems:
+ - A security fix from Debian 1.3.5-5 was inadvertently omitted.
+ - The assembler is now invoked with --noexecstack if supported,
+ so that gzip can better resist stack-smashing attacks.
+
+Major changes in Gzip 1.3.7 (2006-12-06)
+
+* Fix some gzip problems:
+ - Refuse to compress setuid or setgid files, or files with the sticky bit.
+ - Fix more race conditions in setting file permissions and owner,
+ removing output files, following symbolic links, and dealing with
+ special files.
+ - Remove most of the code working around ENAMETOOLONG deficiencies.
+ Systems with those deficiencies are long-dead, and the workarounds
+ had race conditions on modern hosts.
+ - Catch CPU time and file size limit signals, too.
+ - Check for read errors when closing files.
+ - Fix a core dump caused by a stray abort mistakenly introduced in 1.3.6.
+* Fix some gzexe problems:
+ - Improve resistance to denial-of-service attacks.
+ - Fix some quoting and escaping bugs.
+ - Do not assume /tmp is sticky (though it should be!).
+ - Do not assume the working directory can be written.
+ - Rely on PATH in the generated executable, as the man page says.
+ - Don't assume IFS is sane.
+ - Exit with signal's status, if signaled.
+
+Major changes in Gzip 1.3.6 (2006-11-20)
+
+* Fix some race conditions in setting file time stamps, permissions, and owner.
+* Fix some race conditions in signal handling.
+* When gzip exits due to a signal, it exits with the signal's status, not 1.
+* gzip now restores file time stamps to the resolution supported by the
+ time-setting primitives of the operating system, typically 1 microsecond.
+ Formerly it restored them only to the nearest second.
+* gzip -r no longer attempts to reset the last-access times of directories
+ it reads, as this messes up when other processes are reading the directories.
+* The options --version and --help now work on all gzip-installed executables,
+ and now use a format similar to other GNU programs.
+* The manual is now distributed under the terms of the GNU Free
+ Documentation License without invariant sections or cover texts.
+* Port to current versions of Autoconf, Automake, and Gnulib.
+
+Major changes from 1.3.4 to 1.3.5
+* gzip now removes any output symlink before writing output file.
+* zgrep etc. scripts now port to POSIX 1003.1-2001 hosts.
+* zforce no longer assumes 14-byte file name length limit.
+* zless is now implemented using less and LESSOPEN, not zmore and PAGER.
+* assembly-language speedups reenabled; were mistakenly disabled in 1.3.
+
+Major changes from 1.3.3 to 1.3.4
+* Less output is lost when decompressing a truncated file.
+* The manual is now distributed under the terms of the GNU Free
+ Documentation License.
+
+No major changes in 1.3.2 or 1.3.3 (bug fixes only)
+
+Major changes from 1.3 to 1.3.1
+* zgrep now supports --, -H, -h, -L, -l, -C, -d, -m and their long equivalents.
+
+Major changes from 1.2.4 to 1.3
+* Add support for large files, e.g. files larger than 2 GB on Solaris 2.6.
+* Adjust file size listing format for files larger than 10 GB.
+* New command `zless'.
+* `zdiff' now reports exit status like `diff' does.
+* `zcat' is now always called `zcat', not `gzcat'.
+ Similarly for `zdiff', `zgrep', `zmore', `znew', `zforce'.
+* Warn about a compressed file's trailing zeros only if verbose,
+ for compatibility with recent versions of GNU tar.
+* Conform to changes to GNU makefile standards.
+* Port to Autoconf 2.13.
+* Convert to Automake.
+* Fix bugs in the following areas:
+ - files larger than 4 GB
+ - security hole involving symlinks from /tmp
+ - security hole involving long file names
+ - permissions bug when compressing a symbolic link to a file
+ - core dumps
+ - concatenated compressed files on INBUFSIZ boundaries
+ - porting bugs on hosts with signed chars
+ - porting bug with upper and lower case
+ - porting bug for hosts that reserve the names `basename' or `warning'
+
+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
+* Don't display the output name when decompressing except with --verbose.
+* Remove usage of alloca in getopt.c and all makefiles.
+* Added the zfile shell script in subdirectory sample.
+* Moved the list of compiler bugs from README to INSTALL.
+* 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.
+* made gzexe more secure (don't rely on PATH).
+* By default, display output name only when the name was actually truncated.
+
+Major changes from 1.1.2 to 1.2
+* Added the --list option to display the file characteristics.
+* Added the --no-name option: do not save or restore original filename
+ Save the original name by default.
+* 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.

+* Allow suffix other than .gz in znew.
+* Do not display compression ratio when decompressing stdin.
+* In zmore.in, work around brain damaged stty -g (Ultrix).
+* Display a correct compression ratio for .Z files.
+* Added .z to .gz renaming script in INTALL.
+* Allow setting CFLAGS in configure.
+
+Major changes from 1.1 to 1.1.1.
+* Fix serious bug in vms.c (affects Vax/VMS only).
+* Added --ascii option.

+
+Major changes from 1.0.7 to 1.1.
+* Use .gz suffix by default, add --suffix option.
+* Let gunzip accept a "_z" suffix (used by one 'compress' on Vax/VMS).
+* Quit when reading garbage from stdin instead of reporting an error.
+* Added makefile for VAX/MMS and support for wildcards on VMS.
+* Added support for MSC under OS/2.
+* Added support for Prime/PRIMOS.
+* Display compression ratio also when decompressing (with --verbose).
+* Quit after --version (GNU standard)
+* Use --force to bypass isatty() check
+* Continue processing other files in case of recoverable error.
+* Added comparison of zip and gzip in the readme file.

+* 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.

+* Fix the 'OS code' byte in the gzip header.
+* For the Amiga, add the missing utime.h and add support for gcc.
+
+
+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.
+* Use GZIP_OPT for VMS to avoid conflict with program name.
+* ... 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 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.

+* 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.
+
+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: gzip is sensitive to compiler bugs, particularly when
+optimizing. 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.
+
+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 in
+ftp://gatekeeper.dec.com/pub/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 from ftp://ftp.gnu.org/gnu/gzip or in any of the gnu
+mirror sites.
+
+- sources in gzip-*.tar (or .shar or .tar.gz).
+- 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 was compiled with
+ djgpp 1.10 available in directory omnigate.clarkson.edu:/pub/msdos/djgpp.
+
+A VMS executable is in ftp://ftp.spc.edu/[.macro32.savesets]gzip-1-*.zip
+(use [.macro32]unzip.exe to extract). A PRIMOS executable is available
+in ftp://ftp.lysator.liu.se/pub/primos/run/gzip.run.
+
+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 and later 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.
+See http://www.cdrom.com/pub/infozip/ for more about zip and unzip.

+TODO file for gzip.
+
+Some of the planned features include:
+
+- Remove some of the old porting cruft, since we no longer support
+ PRIMOS etc. any more.
+
+- Separate out the shell scripts like gzexe into a new little package;
+ these scripts are less used and less reliable and should be optional.
+
+- Internationalize by using gettext and setlocale.
+
+- 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.
+
+ For one possible approach to this, please see:
+
+ http://www.samba.org/netfilter/diary/gzip.rsync.patch
+
+- 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>.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+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.

+/*
+ * 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.

+%
+% As a special exception, when this file is read by TeX when processing
+% a Texinfo source document, you may use the result without
+% restriction. (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+% http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+% ftp://tug.org/tex/texinfo.tex
+% (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo@gnu.org. Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem. Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+/*
+ * 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.

+
+@display
+Copyright @copyright{} 2000,2001,2002 Free Software Foundation, Inc.
+51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The ``Document'', below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as ``you''. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification. Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''. You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document 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
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation 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. See

+
+1 Overview
+**********
+
+`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 extension is `-gz' for VMS, `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.
+`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, `gzip'
+truncates it. `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, `gzip' keeps the original file name and time stamp 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. However, due to limitations in the current `gzip' file
+format, fractional seconds are discarded. Also, time stamps must fall
+within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 UTC,
+and hosts whose operating systems use 32-bit time stamps are further
+restricted to time stamps no later than 2038-01-19 03:14:07 UTC. The
+upper bounds assume the typical case where leap seconds are ignored.
+
+ 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', `.z', `.Z', `-gz', `-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' or `pack'. The detection of the input format is automatic.
+When using the first two formats, `gunzip' checks a 32 bit CRC (cyclic
+redundancy check). 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.
+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. 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 a `zip' file with a single member, use a
+command like `gunzip <foo.zip' or `gunzip -S .zip foo.zip'. To extract
+`zip' files with several members, use `unzip' instead of `gunzip'.
+
+ `zcat' is identical to `gunzip -c'. `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. 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 `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 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. `gzip' normally preserves
+the mode, ownership and time stamps of files when compressing or
+decompressing.
+
+ The `gzip' file format is specified in P. Deutsch, GZIP file format
+specification version 4.3, Internet RFC 1952
+(ftp://ftp.isi.edu/in-notes/rfc1952.txt) (May 1996). The `zip'
+deflation format is specified in P. Deutsch, DEFLATE Compressed Data
+Format Specification version 1.3, Internet RFC 1951
+(ftp://ftp.isi.edu/in-notes/rfc1951.txt) (May 1996).

+2 Sample Output
+***************
+
+Here are some realistic examples of running `gzip'.
+
+ This is the output of the command `gzip -h':
+
+ Usage: gzip [OPTION]... [FILE]...
+ Compress or uncompress FILEs (by default, compress FILES in-place).
+
+ Mandatory arguments to long options are mandatory for short options too.
+
+ -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, --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
+
+ With no FILE, or when FILE is -, read standard input.
+
+ Report bugs to <bug-gzip@gnu.org>.
+
+ This is the output of the command `gzip -v texinfo.tex':
+
+ texinfo.tex: 69.3% -- replaced with texinfo.tex.gz
+
+ The following command will find all regular `.gz' files in the
+current directory and subdirectories (skipping file names that contain
+newlines), and extract them in place without destroying the original,
+stopping on the first failure:
+
+ find . -name '*
+ *' -prune -o -name '*.gz' -type f -print |

+
+3 Invoking `gzip'
+*****************
+
+The format for running the `gzip' program is:
+
+ gzip OPTION ...
+
+ `gzip' supports the following options:
+
+`--stdout'
+`--to-stdout'
+`-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.
+
+`--decompress'
+`--uncompress'
+`-d'
+ Decompress.
+
+`--force'
+`-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 `gzip', and if the
+ option `--stdout' is also given, copy the input data without
+ change to the standard output: 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.
+
+`--help'
+`-h'
+ Print an informative help message describing the options then quit.
+
+`--list'
+`-l'
+ 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 (deflate,compress,lzh,pack)
+ crc: the 32-bit CRC of the uncompressed data
+ date & time: time stamp for the uncompressed file
+
+ The CRC is given as ffffffff for a file not in gzip format.
+
+ 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.
+
+ The `gzip' format represents the input size modulo 2^32, so the
+ uncompressed size and compression ratio are listed incorrectly for
+ uncompressed files 4 GiB and larger. To work around this problem,
+ you can use the following command to discover a large uncompressed
+ file's true size:
+
+ zcat file.gz | wc -c
+
+`--license'
+`-L'
+ Display the `gzip' license then quit.
+
+`--no-name'
+`-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 `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.
+
+`--name'
+`-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.
+
+`--quiet'
+`-q'
+ Suppress all warning messages.
+
+`--recursive'
+`-r'
+ Travel the directory structure recursively. If any of the file

+
+`--suffix SUF'
+`-S SUF'
+ Use suffix SUF instead of `.gz'. Any suffix can be given, but
+ suffixes other than `.z' and `.gz' should be avoided to avoid

+`-V'
+ Version. Display the version number and compilation options, then
+ quit.
+
+`--fast'
+`--best'
+`-N'
+ Regulate the speed of compression using the specified digit N,
+ where `-1' or `--fast' indicates the fastest compression method

+ compression method (optimal compression). The default compression
+ level is `-6' (that is, biased towards high compression at expense
+ of speed).

+
+4 Advanced usage
+****************
+
+Multiple compressed files can be concatenated. In this case, `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 `gzip' files:
+
+ 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:
+
+ zcat 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:
+
+ zcat 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.
+
+\1f
+File: gzip.info, Node: Environment, Next: Tapes, Prev: Advanced usage, Up: Top
+
+5 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 VMS, the name of the environment variable is `GZIP_OPT', to avoid
+a conflict with the symbol set for invocation of the program.
+
+\1f
+File: gzip.info, Node: Tapes, Next: Problems, Prev: Environment, Up: Top
+
+6 Using `gzip' on 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 `gunzip' for decompression, `gunzip'
+detects that there is extra trailing garbage after the compressed data
+and emits a warning by default if the garbage contains nonzero bytes.
+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-compress /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'.)

+A.1 GNU Free Documentation License
+==================================
+
+ Version 1.2, November 2002
+
+ Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided for under this License. Any other
+ attempt to copy, modify, sublicense or distribute the Document 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.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation 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. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@chapter Overview
+@cindex overview
+
+@command{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 @option{-gz} for @abbr{VMS},
+@samp{z} for @abbr{MSDOS}, @abbr{OS/2} @abbr{FAT} and Atari.)
+If no files are specified or
+if a file name is "-", the standard input is compressed to the standard
+output. @command{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, @command{gzip}
+truncates it. @command{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, @command{gzip} keeps the original file name and time stamp in
+the compressed file. These are used when decompressing the file with the
+@option{-N} option. This is useful when the compressed file name was
+truncated or when the time stamp was not preserved after a file
+transfer. However, due to limitations in the current @command{gzip} file
+format, fractional seconds are discarded. Also, time stamps must fall
+within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15
+@abbr{UTC}, and hosts whose operating systems use 32-bit time
+stamps are further restricted to time stamps no later than 2038-01-19
+03:14:07 @abbr{UTC}. The upper bounds assume the typical case
+where leap seconds are ignored.
+
+Compressed files can be restored to their original form using @samp{gzip -d}
+or @command{gunzip} or @command{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.
+
+@command{gunzip} takes a list of files on its command line and replaces
+each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z},
+@option{-gz}, @option{-z} or @samp{_z} and which begins with the correct
+magic number with an uncompressed file without the original extension.
+@command{gunzip} also recognizes the special extensions @samp{.tgz} and
+@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z}
+respectively. When compressing, @command{gzip} uses the @samp{.tgz}
+extension if necessary instead of truncating a file with a @samp{.tar}
+extension.
+
+@command{gunzip} can currently decompress files created by @command{gzip},
+@command{zip}, @command{compress} or @command{pack}. The detection of the input
+format is automatic. When using the first two formats, @command{gunzip}
+checks a 32 bit @abbr{CRC} (cyclic redundancy check). For @command{pack},
+@command{gunzip} checks the uncompressed length. The @command{compress} format
+was not designed to allow consistency checks. However @command{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 @command{uncompress} does not complain.
+This generally means that the standard @command{uncompress} does not check
+its input, and happily generates garbage output. The @abbr{SCO} @samp{compress
+-H} format (@abbr{LZH} compression method) does not include a @abbr{CRC} but
+also allows some consistency checks.
+
+Files created by @command{zip} can be uncompressed by @command{gzip} only if
+they have a single member compressed with the 'deflation' method. This
+feature is only intended to help conversion of @file{tar.zip} files to
+the @file{tar.gz} format. To extract a @command{zip} file with a single
+member, use a command like @samp{gunzip <foo.zip} or @samp{gunzip -S
+.zip foo.zip}. To extract @command{zip} files with several
+members, use @command{unzip} instead of @command{gunzip}.
+
+@command{zcat} is identical to @samp{gunzip -c}. @command{zcat}
+uncompresses either a list of files on the command line or its standard
+input and writes the uncompressed data on standard output. @command{zcat}
+will uncompress files that have the correct magic number whether they
+have a @samp{.gz} suffix or not.
+
+@command{gzip} uses the Lempel-Ziv algorithm used in @command{zip} and
+@abbr{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 @abbr{LZW} (as used in @command{compress}), Huffman
+coding (as used in @command{pack}), or adaptive Huffman coding
+(@command{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 @command{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. @command{gzip} normally preserves the mode,
+ownership and time stamps of files when compressing or decompressing.
+
+The @command{gzip} file format is specified in P. Deutsch, @sc{gzip} file
+format specification version 4.3,
+@uref{ftp://ftp.isi.edu/in-notes/rfc1952.txt, Internet @abbr{RFC} 1952} (May
+1996). The @command{zip} deflation format is specified in P. Deutsch,
+@sc{deflate} Compressed Data Format Specification version 1.3,
+@uref{ftp://ftp.isi.edu/in-notes/rfc1951.txt, Internet @abbr{RFC} 1951} (May
+1996).

+@node Sample
+@chapter Sample Output
+@cindex sample
+
+Here are some realistic examples of running @command{gzip}.
+
+This is the output of the command @samp{gzip -h}:
+
+@example
+Usage: gzip [OPTION]... [FILE]...
+Compress or uncompress FILEs (by default, compress FILES in-place).
+
+Mandatory arguments to long options are mandatory for short options too.
+
+ -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, --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
+
+With no FILE, or when FILE is -, read standard input.
+
+Report bugs to <bug-gzip@@gnu.org>.
+@end example
+
+This is the output of the command @samp{gzip -v texinfo.tex}:
+
+@example
+texinfo.tex: 69.3% -- replaced with texinfo.tex.gz
+@end example
+
+The following command will find all regular @samp{.gz} files in the
+current directory and subdirectories (skipping file names that contain
+newlines), and extract them in place without destroying the original,
+stopping on the first failure:
+
+@example
+find . -name '*
+*' -prune -o -name '*.gz' -type f -print |
+ sed "
+ s/'/'\\''/g
+ s/^\\(.*\\)\\.gz$/gunzip <'\\1.gz' >'\\1'/
+ " |
+ sh -e
+@end example
+
+@node Invoking gzip
+@chapter Invoking @command{gzip}
+@cindex invoking
+@cindex options
+
+The format for running the @command{gzip} program is:
+
+@example
+gzip @var{option} @dots{}
+@end example
+
+@command{gzip} supports the following options:
+
+@table @option
+@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 @command{gzip}, and if the option @option{--stdout} is also
+given, copy the input data without change to the standard output: let
+@command{zcat} behave as @command{cat}. If @option{-f} is not given, and
+when not running in the background, @command{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 @minus{}1 for files not in @command{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 @option{--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 @abbr{CRC} is given as ffffffff for a file not in gzip format.
+
+With @option{--verbose}, the size totals and compression ratio for all files
+is also displayed, unless some sizes are unknown. With @option{--quiet},
+the title and totals lines are not displayed.
+
+The @command{gzip} format represents the input size modulo
+@math{2^32}, so the uncompressed size and compression ratio are listed
+incorrectly for uncompressed files 4 GiB and larger. To work around
+this problem, you can use the following command to discover a large
+uncompressed file's true size:
+
+@example
+zcat file.gz | wc -c
+@end example
+
+@item --license
+@itemx -L
+Display the @command{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 @command{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, @command{gzip} will descend
+into the directory and compress all the files it finds there (or
+decompress them in the case of @command{gunzip}).
+
+@item --suffix @var{suf}
+@itemx -S @var{suf}
+Use suffix @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 @command{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 @option{-1} or @option{--fast} indicates the fastest compression
+method (less compression) and @option{--best} or @option{-9} indicates the
+slowest compression method (optimal compression). The default
+compression level is @option{-6} (that is, biased towards high compression at
+expense of speed).
+@end table
+
+@node Advanced usage
+@chapter Advanced usage
+@cindex concatenated files
+
+Multiple compressed files can be concatenated. In this case,
+@command{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 @command{gzip} files:
+
+@example
+gzip -c file1 > foo.gz
+gzip -c file2 >> foo.gz
+@end example
+
+@noindent
+Then
+
+@example
+gunzip -c foo
+@end example
+
+@noindent
+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
+
+@noindent
+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 @abbr{CRC} reported by the @option{--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 @command{tar} or @command{zip}. @acronym{GNU} @command{tar}
+supports the @option{-z}
+option to invoke @command{gzip} transparently. @command{gzip} is designed as a
+complement to @command{tar}, not as a replacement.
+
+@node Environment
+@chapter Environment
+@cindex Environment
+
+The environment variable @env{GZIP} can hold a set of default options for
+@command{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 @abbr{VMS}, the name of the environment variable is @env{GZIP_OPT}, to
+avoid a conflict with the symbol set for invocation of the program.
+
+@node Tapes
+@chapter Using @command{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 @command{gunzip} for decompression,
+@command{gunzip} detects that there is extra trailing garbage after the
+compressed data and emits a warning by default if the garbage contains
+nonzero bytes. You have to use the
+@option{--quiet} option to suppress the warning. This option can be set in the
+@env{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, @command{gzip} is invoked implicitly by the @option{-z}
+option of @acronym{GNU} @command{tar}. Make sure that the same block
+size (@option{-b}
+option of @command{tar}) is used for reading and writing compressed data on
+tapes. (This example assumes you are using the @acronym{GNU} version of
+@command{tar}.)

+.TH GZEXE 1
+.SH NAME
+gzexe \- compress executable files in place
+.SH SYNOPSIS
+.B gzexe
+.I "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 /usr/bin/gdb'' it
+will create the following two files:
+.nf
+.br
+ -rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
+ -rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
+.fi
+/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing
+executable file. You can remove /usr/bin/gdb~ once you are sure that
+/usr/bin/gdb 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 standard utilities
+.RI ( basename ,
+.IR chmod ,
+.IR ln ,
+.IR mkdir ,
+.IR mktemp ,
+.IR rm ,
+.IR sleep ,
+and
+.IR tail ).
+.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
+.IR chown .

+.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 a
+.I zip
+file with a single member, use a command like
+.I "gunzip <foo.zip"
+or
+.IR "gunzip -S .zip foo.zip" .
+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.
+.PP
+The
+.I gzip
+file format is specified in P. Deutsch, \s-1GZIP\s0 file format
+specification version 4.3, <ftp://ftp.isi.edu/in-notes/rfc1952.txt>,
+Internet RFC 1952 (May 1996). The
+.I zip
+deflation format is specified in P. Deutsch, \s-1DEFLATE\s0 Compressed
+Data Format Specification version 1.3,
+<ftp://ftp.isi.edu/in-notes/rfc1951.txt>, Internet RFC 1951 (May 1996).
+
+.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 output: 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
+
+On Vax/VMS, the name of the environment variable is GZIP_OPT, to
+avoid a conflict with the symbol set for invocation of the program.

+.SH "DIAGNOSTICS"
+Exit status is normally 0;
+if an error occurs, exit status is 1. If a warning occurs, exit status is 2.
+.TP
+Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
+Invalid options were specified on the command line.
+.TP
+\fIfile\fP\^: not in gzip format
+The file specified to
+.I gunzip
+has not been compressed.
+.TP
+\fIfile\fP\^: 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 \fIfile\fP > recover
+.TP
+\fIfile\fP\^: compressed with \fIxx\fP bits, can only handle \fIyy\fP bits
+.I File
+was compressed (using LZW) by a program that could deal with
+more
+.I bits
+than the decompress code on this machine.
+Recompress the file with gzip, which compresses better and uses
+less memory.
+.TP
+\fIfile\fP\^: already has .gz suffix -- no change
+The file is assumed to be already compressed.
+Rename the file and try again.
+.TP
+\fIfile\fP already exists; do you wish to overwrite (y or n)?
+Respond "y" if you want the output file to be replaced; "n" if not.
+.TP
+gunzip: corrupt input
+A SIGSEGV violation was detected which usually means that the input file has
+been corrupted.
+.TP
+\fIxx.x%\fP Percentage of the input saved by compression.
+(Relevant only for
+.BR \-v
+and
+.BR \-l \.)
+.TP
+-- not a regular file or directory: ignored
+When the input file is not a regular file or directory,
+(e.g. a symbolic link, socket, FIFO, device file), it is
+left unaltered.
+.TP
+-- has \fIxx\fP other links: unchanged
+The input file has links; it is left unchanged. See
+.IR ln "(1)"
+for more information. Use the
+.B \-f
+flag to force compression of multiply-linked files.
+.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 gzip format represents the input size modulo 2^32, so the
+--list option reports incorrect uncompressed sizes and compression
+ratios for uncompressed files 4 GB and larger. To work around this
+problem, you can use the following command to discover a large
+uncompressed file's true size:
+
+ zcat file.gz | wc -c
+
+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.

+GZIP(1) GZIP(1)
+
+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 modi-
+ fication times. (The default extension 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
+ output. Gzip will only attempt to compress regular files. In particu-
+ lar, it will ignore symbolic links.
+
+ If the compressed file name is too long for its file system, gzip trun-
+ cates it. 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, gzip keeps the original file name and timestamp in the com-
+ pressed 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 output. 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 a zip file with a single member, use a command like gunzip
+ <foo.zip or gunzip -S .zip foo.zip. 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 dis-
+ tribution 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 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 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. gzip preserves the mode,
+ ownership and timestamps of files when compressing or decompressing.
+
+ The gzip file format is specified in P. Deutsch, GZIP file format spec-
+ ification version 4.3, <ftp://ftp.isi.edu/in-notes/rfc1952.txt>, Inter-
+ net RFC 1952 (May 1996). The zip deflation format is specified in P.
+ Deutsch, DEFLATE Compressed Data Format Specification version 1.3,
+ <ftp://ftp.isi.edu/in-notes/rfc1951.txt>, Internet RFC 1951 (May 1996).
+
+OPTIONS
+ -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 con-
+ verted 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 output 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 com-
+ pressed data is read from or written 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 standard output: 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 for-
+ mat, 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, com-
+ press, 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 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.
+
+ -q --quiet
+ Suppress all warnings.
+
+ -r --recursive
+ Travel the directory structure recursively. If any of the file
+ names specified on the command line are directories, 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 confu-
+ sion when files are transferred to other systems. A null suffix
+ forces gunzip to try decompression on all given files regard-
+ less 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 com-
+ pression method (best compression). 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 independently, use an archiver such
+ as tar or zip. GNU tar supports the -z option to invoke gzip transpar-
+ ently. 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 invocation 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. Recom-
+ press 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 directory, (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 multi-
+ ply-linked files.
+
+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 gunzip for decompression, 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 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 gzip format represents the input size modulo 2^32, so the --list
+ option reports incorrect uncompressed sizes and compression ratios for
+ uncompressed files 4 GB and larger. To work around this problem, you
+ can use the following command to discover a large uncompressed file's
+ true size:
+
+ zcat file.gz | wc -c
+
+ The --list option reports sizes as -1 and crc as ffffffff if the com-
+ pressed 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, com-
+ press compresses better than gzip.

+/*
+ 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 multi-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.

+ 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.

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ 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.
+
+ 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.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options.
+
+ If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT

+
+ - <stdbool.h> must be #included before 'bool', 'false', 'true'
+ can be used.
+
+ - You cannot assume that sizeof (bool) == 1.
+
+ - Programs should not undefine the macros bool, true, and false,

+
+ Limitations of this substitute, when used in a C89 environment:
+
+ - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+ - You cannot assume that _Bool is a typedef; it might be a macro.
+
+ - Bit-fields of type 'bool' are not supported. Portable code
+ should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+ - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+ performed in such a way that every nonzero value gets converted
+ to 'true', and zero gets converted to 'false'. This doesn't work
+ with this substitute. With this substitute, only the values 0 and 1
+ give the expected result when converted to _Bool' or 'bool'.

+To build GZIP for PRIMOS you should just have to type:
+
+ r *>primos>build
+
+while standing in the directory above this PRIMOS subdirectory.
+
+If the files in these directories looks strange, then it might be
+because they are in normal ASCII. You'll need to convert them into
+PASCII before you will be able to build the GZIP executable.
+
+You can find a simple ASCII to PASCII converter via anonymous FTP
+from "ftp.lysator.liu.se" in the directory "pub/primos/run" as
+the file "topascii.run".
+
+You can reach me at a number of places in case there are any bugs
+in this port to report...

+
+ 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.

+
+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 output: 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.

+If only 1 file is specified, then the files compared are
+.I file1
+and an uncompressed
+.IR file1 ".gz."
+If two files are specified, then they are uncompressed if necessary and fed to
+.I cmp
+or
+.IR diff "."
+The exit status from
+.I cmp
+or
+.I diff
+is preserved.

+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
+is truncated to make room for the .gz suffix. For example,

+.SH NAME
+zless \- file perusal filter for crt viewing of compressed text
+.SH SYNOPSIS
+.B zless
+[ name ... ]
+.SH DESCRIPTION
+.I Zless
+is a filter which allows examination of compressed or plain text files
+one screenful at a time on a soft-copy terminal. It is the equivalent of
+setting the environment variable LESSOPEN to '|gzip -cdfq -- %s',
+and the environment variable LESSMETACHARS to
+'<space><tab><newline>;*?"()<>[|&^`#\$%=~',
+and then running
+.IR less .
+However, enough people seem to think that having the
+command
+.I zless
+available is important to be worth providing it.
+.SH "SEE ALSO"
+zmore(1), less(1)
+.SH "BUGS"
+.I Zless
+does not work with compressed data that is piped to it via standard
+input; it requires that input files be specified as arguments.

+.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" is 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.
