GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our 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. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, 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 a 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 tell them 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.
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 Agreement 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 work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
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
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual 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 General
Public License.
d) 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.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 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
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying 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.
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.
7. 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 the 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
the license, you may choose any version ever published by the Free Software
Foundation.
8. 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
9. 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.
10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, or (at your option)
any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx 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 a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

Thu Aug 8 00:15:33 1991 David J. MacKenzie (djm at bleen)
* Version 1.08.
* sed.c (compile_filename): If reading a file fails, read
/dev/null instead. It's what Unix and POSIX do, effectively.
* sed.c (compile_regex): The 'slash' character doesn't
terminate the regex if it's in a character class.
* sed.c (main): If given no args, or bad option, print usage
message.
(usage): New function.
* sed.c (execute_program): Amount written for 'P' command was
wrong. From stephend@ksr.com (Stephen Davis).
Wed Aug 7 16:51:14 1991 David J. MacKenzie (djm at apple-gunkies)
* sed.c (append_pattern_space): Check for buffer full before
instead of after writing to buffer. Don't need to test for
EOF initially anymore, due to the next change.
(execute_program): For 'n' and 'N' commands, if eof is reached
in input, quit the script like Unix sed does.
Fix memory allocation problems for 'a' and 'r' commands.
(compile_program): Fix off by one error in processing comments.
All of the above are from Tapani Tarvainen, tarvaine@tukki.jyu.fi.
* sed.c (setup_jump): Use isblank instead of testing for ' '
or '\t', for POSIX locales.
* utils.c (ck_strdup): Renamed from strdup.
* sed.c: Change callers.
* sed.c, utils.c: Clean up declarations and includes to get
rid of compiler warnings.
* sed.c (main): Add long-named options. Don't complain if -n
is given twice.
Fri Aug 2 12:33:16 1991 David J. MacKenzie (djm at apple-gunkies)
* configure: Support +srcdir arg. Create config.status and
remove it and Makefile if interrupted while creating them.
* Makefile.in: Change DESTDIR to prefix.
Mon Jul 15 13:07:39 1991 David J. MacKenzie (djm at wookumz.gnu.ai.mit.edu)
* sed.c (main): Add -V option to print version number.
(USAGE): Mention -V.
Mon Jul 8 01:42:22 1991 David J. MacKenzie (djm at geech.gnu.ai.mit.edu)
* sed.c: Define bcopy in terms of memcpy if STDC_HEADERS as
well as if USG.
(compile_filename): Don't glob filename (for 'r' and 'w'
commands). Unix sed doesn't do it and it's not very useful,
since it can only match 0 or 1 files.
(execute_program): Change '\a' to 007 since some compilers
don't recognize \a.
* utils.c: New file; code moved from sed.c.
* Replace Makefile with Makefile.in and configure.
Update README.
Tue Mar 26 13:00:48 EST 1991 Jay Fenlason (hack@gnu.ai.mit.edu)
* sed.c (match_address) Added a trivial cast for portability.
Mon Feb 25 13:23:29 EST 1991 Jay Fenlason (hack@ai.mit.edu)
* sed.c Changed 's' command to work with latest version of regex()
routines, which mysteriously changed somewhere in there. . .
A one-line patch from David Eckelkamp (eckelkamp@mcc.com).
Initialize the fastmap in the hopes that it'll make sed faster.
Thu Feb 21 13:42:27 EST 1991 Jay Fenlason (hack@ai.mti.edu)
* sed.c Change panic to compile with other __STDC__ compilers.
Wed Jan 30 10:46:38 EST 1991 Jay Fenlason (hack@ai.mit.edu)
* sed.c Changed version number. Made new release.
Tue Nov 27 15:34:51 EST 1990 Jay Fenlason (hack@ai.mit.edu)
* sed.c (setup_jump) Don't blow chunks if there isn't a label
after a b or t command.
(main) Don't panic if it a branch command doesn't have
a label to branch to.
(main) Collect all the -e arguments together and parse them
all at once. This way, -e { -e mumble -e } will work.
All these small patches from David Schmidt (davids@isc-br.isc-br.com)
Tue Sep 11 12:51:37 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* sed.c Changed some function forward declarations to use VOID *
instead of char *

returns NULL.
Thu Apr 5 21:41:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
* sed.c (execute_program, case 'r'): When need to realloc append.text,
multiply append.alloc by 2 instead of adding
cur_cmd->x.cmd_txt.text_len.
Tue Mar 6 15:55:35 EST 1990 Jay Fenlason (hack@ai.mit.edu)
* sed.c (compile_regex) Allocate 10 bytes extra space needed by
re_compile_pattern.
Sun Feb 25 16:32:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
* sed.c (execute_program, case 'l'): Print \00 instead of \0.
Print backslash as \\ not \.
Print \xx instead of /xx.
Thu Feb 1 14:02:28 EST 1990 hack@wookumz
* sed.c (memchr) Use () inside inner loop so it will work correctly.
A two character patch from Robert A Bruce (rab@allspice.berkeley.edu)
Wed Sep 27 18:47:39 EDT 1989 hack@ai.mit.edu
* sed.c (compile_regex) New function. When compiling regex,
turn ^ into \` and $ into \' so that they won't match on embedded
newlines. UN*X pattern matching is a crock.
(compile_program, compile_address) call compile_regex.
Mon Sep 18 10:15:32 EDT 1989 hack@ai.mit.edu
* sed.c (compile_program): define translate as unsigned char * so

This directory contains GNU sed. Please report all bugs and comments
to bug-gnu-utils@prep.ai.mit.edu.
This sed may run slower than some UN*X seds. This is because it uses
the regular-expression routines from Emacs, which are rather complete
and powerful, but not as fast as they could be. If you really care
about speed, use perl instead.
To compile:
1. Type `sh configure'. This shell script attempts to guess correct
values for various system-dependent variables used during compilation,
and creates the file `Makefile'. This takes a minute or so.
If you want to compile in a different directory from the one
containing the source code, `cd' to that directory and run `configure'
with the option `+srcdir=DIR', where DIR is the directory that
contains the source code. The object files and executables will be
put in the current directory. This option only works with versions of
`make' that support the VPATH variable. `configure' ignores any other
arguments you give it.
If your system requires unusual options for compilation or linking
that `configure' doesn't know about, you can give `configure' initial
values for variables by setting them in the environment; in
Bourne-compatible shells, you can do that on the command line like
this:
$ CC='gcc -traditional' LIBS=-lposix sh configure
2. If you want to change the directories where the program will be
installed, or the optimization options, edit `Makefile' and change
those values. If you have an unusual system that needs special
compilation options that `configure' doesn't know about, and you
didn't pass them in the environment when running `configure', you
should add them to `Makefile' now. Alternately, teach `configure' how
to figure out that it is being run on a system where they are needed,
and mail the diffs to the address listed at the top of this file so we
can include them in the next release.
3. Type `make'.
4. If the program compiles successfully, type `make install' to
install it.
5. After you have installed the program, you can remove the binary
from the source directory by typing `make clean'. Type `make
distclean' if you also want to remove `Makefile', for instance if you
are going to recompile sed next on another type of machine.

REQUIRE_ORDER means don't recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable _POSIX_OPTION_ORDER, or using `+' as the first character
of the list of option characters.
PERMUTE is the default. We permute the contents of ARGV as we scan,
so that eventually all the non-options are at the end. This allows options
to be given in any order, even with programs that were not written to
expect this.
RETURN_IN_ORDER is an option available to programs that were written
to expect options and other ARGV-elements in any order and that care about
the ordering of the two. We describe each non-option ARGV-element
as if it were the argument of an option with character code 1.
Using `-' as the first character of the list of option characters
selects this mode of operation.
The special argument `--' forces an end of option-scanning regardless
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
`--' can cause `getopt' to return EOF with `optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
given in OPTSTRING.
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 `EOF'.
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
otherwise. */
