GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330
Boston, MA 02111-1307, USA.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; see the file COPYING. If not, write to
the Free Software Foundation, Inc., 59 Temple Place - Suite 330,
Boston, MA 02111-1307, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

write to it unless `tmp', `new' and `cur' subdirectories exist
Sun Oct 28 13:02:10 CET 2001 Daniel Spiljar <dspiljar@bofhlet.net>
* src/info.c, doc/mboxgrep.texi, doc/mboxgrep.1

forgot to document it
Sat Oct 27 21:48:36 CEST 2001 Daniel Spiljar <dspiljar@bofhlet.net>
* src/scan.c:
if the input is a non-mbox folder, a proper postmark line (with
date) is put on top of each message written to stdout
Mon Oct 8 22:53:34 CEST 2001 Daniel Spiljar <dspiljar@bofhlet.net>
* src/*:
source code now completely rewritten
Sun May 27 00:19:52 CEST 2001 Daniel Spiljar <dspiljar@public.srce.hr>

updated the manual page -- it now refers to RFC 2822, instead
of the obsoleted 822
Tue May 1 15:06:03 CEST 2001 Daniel Spiljar <dspiljar@public.srce.hr>
* configure.in, doc/Makefile.in, src/Makefile.in, Makefile.in:

Changes of mboxgrep
===================
Changes since 0.7.8
- implemented support for mbox folders compressed with bzip2 algorithm
- improved detection of PCRE library; this also fixes a compilation bug
on recent RedHat Linux systems
- fixed a problem with message deletion, which used to occur if an mbox
folder and temporary directory were on different filesystems;
thanks to James P. Dugal <jpd@louisiana.edu> for providing a patch
Changes since 0.7.7
- fixed crashes on MH folders, as well as a potential problem with mbox
and maildir folders with the same cause
- debugging with dmalloc library
- MH and maildir functions no longer read files which aren't RFC 2822 messages
- mboxgrep can now read gzip compressed mbox folders from standard input
(which is a side effect of a code cleanup!)
Changes since 0.7.6a
- mboxgrep can now read mbox folders from standard input
Changes since 0.7.6
- fixed a bug which prevented mboxgrep from being compiled
Changes since 0.7.5
- fixed a bug which caused mboxgrep to coredump on recursive search of
maildirs
- code cleanups
Changes since 0.7.4
- recursive search through directories has been reimplemented
Changes since 0.7.3
- mboxgrep can now ignore messages with identical bodies
Changes since 0.7.2
- file locking method can be selected at runtime
- mboxgrep used to coredump on messages with empty headers; the problem is
now hopefully fixed
- mboxgrep now compiles on FreeBSD
Changes since 0.7.1
- file locking with flock() instead of fcntl() is now supported
- mboxgrep should now compile on systems which don't have getopt_long()
- other minor bugfixes
Changes since 0.7.0
- bugfixes
Changes since 0.5.3
- NOTE: there was no stable version between 0.5.x and 0.7.x
- mboxgrep is almost completely rewritten
- implemented message deleting feature (--delete)
- implemented piping messages to a command (--pipe) (using this option,
each selected message is piped to a separate instance of the specified
command)
- added support for compressed mbox folders
Changes since 0.5.2
- implemented ability to write found messages to another folder (instead
of stdout)
- started writing *real* changelog (while this file has been renamed to
"NEWS")
- wrote a manual in Texinfo format
Changes since 0.5.1
- implemented message counting (-c, --count)
- fixed manual page installation target in src/Makefile.in -- manual page
is now installed in $(manpath)/man1/ rather than in $(prefix)/man/man1/
- added `--without-sense-of-humor' switch to the configure script, which
disables checking whether Garfield still hates Mondays
- short version of `--version' switch is now `-V' instead of `-v',
because `-v' will be used for inverted matching
- implemented inverted matching (-v, --invert-match)
- implemented recursive search through directories (-r, --recursive)
- config.h[.in] is now wrapped (#ifndef CONFIG_H and stuff)
Changes since 0.5.0
- added support for qmail-style maildir folders
Changes since 0.4.0
- source of getopt_long() is now included, so long options are also available
on platforms that don't use GNU libc
- file locking is now performed on mbox folders only
Changes since 0.2.0
- added support for MH mailboxes
- added scope selection switches `-B' (or `--body') and `-H' (or `--headers')
- getopt() (or getopt_long(), if available) is now used to parse command line
arguments, instead of my own lousy routine
- configure script now looks for PCRE by default, unless `--with-pcre=no' or
`--without-pcre' is specified
- the feature of reading from standard input is gone
- added `-v' (or `--version') switch
Changes since 0.1.1
- mboxgrep now puts a shared lock on a mailbox before reading it
- various code cleanups
Changes since 0.1.0
- fixed install target in Makefile (`install' is now used instead of `cp')
- added support for mailboxes generated by Gnus

@chapter Introduction
@cindex introduction
@cindex preface
@code{mboxgrep} is a small, non-interactive utility that scans mail folders
for messages matching regular expressions.
It supports basic and extended POSIX regular expressions. @code{Perl}-style
regular expressions are supported as well, if @code{mboxgrep} is linked with
PCRE library.
Found messages can be either displayed on standard output, counted, deleted,
piped to a specified command, or copied to another mailbox.
It can read and write a variety of folder formats:
@itemize @bullet
@item
mbox folders, either plain or compressed
@item
MH folders
@item nnml and nnmh folders used by Gnus
@item @code{qmail}-style maildirs
@end itemize
Additionally, it can read mbox folders or output from another @code{mboxgrep}
process from standard input. It does so if a single dash (-) is given
as a file name.
@node Invoking, Examples, Introduction, Top
@chapter Command-Line Arguments
@cindex arguments
The syntax of @code{mboxgrep} invocation is:

Display program version and copyright information and exit.
@item --recursive
@itemx -r
Descend into directories recursively.
@end table
@node File locking, Regexp selection, Miscellaneous, Invoking
When accessing mbox folders, @code{mboxgrep} puts a shared lock on
files by default. Note that mbox folders normally should not be accessed
without locking.
@table @samp
@item --file-lock=METHOD
@itemx -l METHOD
Specify file locking METHOD. @code{mboxgrep} supports @code{flock} and
@code{fcntl} file locking. However, one of these methods may be
unimplemented on your operating system and thus not available in
@code{mboxgrep} at run time. To disable file locking, specify @code{none}.
@item --no-file-lock
@itemx -nl
Do not attempt to lock mbox folder files.

PATTERN is an extended regular expression.
@item --basic-regexp
@itemx -G
PATTERN is a basic regular expression.
@item --perl-regexp
@itemx -P
PATTERN is a Perl regular expression.
@item --regexp=PATTERN
@itemx -e PATTERN
Use PATTERN as a regular expression.
@item --ignore-case
@itemx -i
Perform case-insensitive search.
@item --invert-match
@itemx -v
Invert the sense of matching, i.e. select only non-matching messages.
@end table
@node Output control, Search scope selection, Regexp selection, Invoking
By default, @code{mboxgrep} writes found messages to standard output.
The options below change such behavior.
@table @samp
@item --count
@itemx -c
Suppress normal output and print the count of matching (or non-matching,
if used with the @code{-v} option) messages.
@item --delete
@itemx -d
Suppress normal output and delete selected messages.
Use with extreme caution.
@item --no-duplicates
@itemx -nd
Ignore duplicate messages.
@item --output=FOLDER
@itemx -o FOLDER
Suppress normal output and write messages to destination folder FOLDER
instead.
Note that @code{mboxgrep} assumes the output folder is of the same format
as the input folder. Currently there is no possibility to convert folders.
@item --pipe=COMMAND
@itemx -p COMMAND
Suppress normal output and pipe each selected message to a separate
instance of COMMAND.
@item --no-messages
@itemx -s
Suppress error messages.
@end table
@node Search scope selection, Mailbox type selection, Output control, Invoking
@table @samp
@item --headers
@itemx -H

@end table
@node Mailbox type selection, , Search scope selection, Invoking
@table @samp
@item --mailbox-format=FORMAT
@itemx -m FORMAT
Specify mailbox FORMAT. Supported formats are @code{mbox} (default),
@code{zmbox} (gzip compressed mbox), @code{bz2mbox} (bzip2 compressed
mbox) @code{mh}, @code{nnml}, @code{nnmh}, and @code{maildir}.

@cindex example
Scan @env{$MAIL} for messages from Dirty Harry:
@example
mboxgrep -H '^From:.*callahan@@homicide\.SFPD\.gov' $MAIL
@end example
Re-mail to George messages that mention his name:
@example
mboxgrep --pipe="/usr/lib/sendmail george" --ignore-case george ~/Mail/*
@end example
Display all messages in folder @file{~/Mail/incoming}, except those that
appear to originate from AOL:
@example
mboxgrep -v -H '^Received:.*aol\.com' ~/Mail/incoming
@end example
Do a case-insensitive scan of @file{~/Mail/incoming} for messages with subject
``Weekly News'' and write them to folder @file{~/Mail/archive}:
@example
mboxgrep -o ~/Mail/archive -H -i '^Subject: Weekly News' ~/Mail/incoming

Title: mboxgrep
Version: 0.7.9
Entered-date: 2003-08-24
Description: mboxgrep is a small utility that scans a mailbox for messages
matching a basic, extended, or Perl-compatible regular
expression. Selected messages can be either displayed on
standard output, counted, piped to a command or written to
another mailbox.
It supports mbox (both plain and compressed), MH, nnmh, nnml
and maildir folders.
Keywords: mail, mail-tools, mbox, MH, nnmh, nnml, maildir, regex

when it is done, all the options precede everything else. Thus
all application programs are extended to handle flexible argument order.

If the caller did not specify anything,
the default is REQUIRE_ORDER if the environment variable

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 POSIXLY_CORRECT, 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
if the `flag' field is zero.
The elements of ARGV aren't really const, because we permute them.
But we pretend they're const in the prototype to be compatible
with other systems.
LONGOPTS is a vector of `struct option' terminated by an
element containing a name which is zero.
LONGIND returns the index in LONGOPT of the long-named option found.
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. */

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

zero.
The field `has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `getopt'
returns the contents of the `val' field. */
