+ 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) <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., 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) 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 Library General
+Public License instead of this License.

+PHP-gettext 1.0
+
+Copyright 2003, 2006 -- Danilo "angry with PHP[1]" Segan
+Licensed under GPLv2 (or any later version, see COPYING)
+
+[1] PHP is actually cyrillic, and translates roughly to
+ "works-doesn't-work" (UTF-8: Ради-Не-Ради)
+
+
+Introduction
+
+ How many times did you look for a good translation tool, and
+ found out that gettext is best for the job? Many times.
+
+ How many times did you try to use gettext in PHP, but failed
+ miserably, because either your hosting provider didn't support
+ it, or the server didn't have adequate locale? Many times.
+
+ Well, this is a solution to your needs. It allows using gettext
+ tools for managing translations, yet it doesn't require gettext
+ library at all. It parses generated MO files directly, and thus
+ might be a bit slower than the (maybe provided) gettext library.
+
+ PHP-gettext is a simple reader for GNU gettext MO files. Those
+ are binary containers for translations, produced by GNU msgfmt.
+
+Why?
+
+ I got used to having gettext work even without gettext
+ library. It's there in my favourite language Python, so I was
+ surprised that I couldn't find it in PHP. I even Googled for it,
+ but to no avail.
+
+ So, I said, what the heck, I'm going to write it for this
+ disguisting language of PHP, because I'm often constrained to it.
+
+Features
+
+ o Support for simple translations
+ Just define a simple alias for translate() function (suggested
+ use of _() or gettext(); see provided example).
+
+ o Support for ngettext calls (plural forms, see a note under bugs)
+ You may also use plural forms. Translations in MO files need to
+ provide this, and they must also provide "plural-forms" header.
+ Please see 'info gettext' for more details.
+
+ o Support for reading straight files, or strings (!!!)
+ Since I can imagine many different backends for reading in the MO
+ file data, I used imaginary abstract class StreamReader to do all
+ the input (check streams.php). For your convenience, I've already
+ provided two classes for reading files: FileReader and
+ StringReader (CachedFileReader is a combination of the two: it
+ loads entire file contents into a string, and then works on that).
+ See example below for usage. You can for instance use StringReader
+ when you read in data from a database, or you can create your own
+ derivative of StreamReader for anything you like.
+
+
+Bugs
+
+ Plural-forms field in MO header (translation for empty string,
+ i.e. "") is treated according to PHP syntactic rules (it's
+ eval()ed). Since these should actually follow C syntax, there are
+ some problems.
+
+ For instance, I'm used to using this:
+ Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
+ n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2;
+ but it fails with PHP (it sets $plural=2 instead of 0 for $n==1).
+
+ The fix is usually simple, but I'm lazy to go into the details of
+ PHP operator precedence, and maybe try to fix it. In here, I had
+ to put everything after the first ':' in parenthesis:
+ Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
+ (n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);
+ That works, and I'm satisfied.
+
+ Besides this one, there are probably a bunch of other bugs, since
+ I hate PHP (did I mention it already? no? strange), and don't
+ know it very well. So, feel free to fix any of those and report
+ them back to me at <danilo@kvota.net>.
+
+Usage
+
+ Put files streams.php and gettext.php somewhere you can load them
+ from, and require 'em in where you want to use them.
+
+ Then, create one 'stream reader' (a class that provides functions
+ like read(), seekto(), currentpos() and length()) which will
+ provide data for the 'gettext_reader', with eg.
+ $streamer = new FileStream('data.mo');
+
+ Then, use that as a parameter to gettext_reader constructor:
+ $wohoo = new gettext_reader($streamer);
+
+ If you want to disable pre-loading of entire message catalog in
+ memory (if, for example, you have a multi-thousand message catalog
+ which you'll use only occasionally), use "false" for second
+ parameter to gettext_reader constructor:
+ $wohoo = new gettext_reader($streamer, false);
+
+ From now on, you have all the benefits of gettext data at your
+ disposal, so may run:
+ print $wohoo->translate("This is a test");
+ print $wohoo->ngettext("%d bird", "%d birds", $birds);
+
+ You might need to pass parameter "-k" to xgettext to make it
+ extract all the strings. In above example, try with
+ xgettext -ktranslate -kngettext:1,2 file.php
+ what should create messages.po which contains two messages for
+ translation.
+
+ I suggest creating simple aliases for these functions (see
+ example/pigs.php for how do I do it, which means it's probably a
+ bad way).
+
+
+Usage with gettext.inc (standard gettext interfaces emulation)
+
+ Check example in examples/pig_dropin.php, basically you include
+ gettext.inc and use all the standard gettext interfaces as
+ documented on:
+
+ http://www.php.net/gettext
+
+ The only catch is that you can check return value of setlocale()
+ to see if your locale is system supported or not.
+
+
+Example
+
+ See in examples/ subdirectory. There are a couple of files.
+ pigs.php is an example, serbian.po is a translation to Serbian
+ language, and serbian.mo is generated with
+ msgfmt -o serbian.mo serbian.po
+ There is also simple "update" script that can be used to generate
+ POT file and to update the translation using msgmerge.
+
+Interesting TODO:
+
+ o Try to parse "plural-forms" header field, and to follow C syntax
+ rules. This won't be easy.
+
+Boring TODO:
+
+ o Learn PHP and fix bugs, slowness and other stuff resulting from
+ my lack of knowledge (but *maybe*, it's not my knowledge that is
+ bad, but PHP itself ;-).
+
+ (This is mostly done thanks to Nico Kaiser.)
+
+ o Try to use hash tables in MO files: with pre-loading, would it
+ be useful at all?
+
+Never-asked-questions:
+
+ o Why did you mark this as version 1.0 when this is the first code
+ release?
+
+ Well, it's quite simple. I consider that the first released thing
+ should be labeled "version 1" (first, right?). Zero is there to
+ indicate that there's zero improvement and/or change compared to
+ "version 1".
+
+ I plan to use version numbers 1.0.* for small bugfixes, and to
+ release 1.1 as "first stable release of version 1".
+
+ This may trick someone that this is actually useful software, but
+ as with any other free software, I take NO RESPONSIBILITY for
+ creating such a masterpiece that will smoke crack, trash your
+ hard disk, and make lasers in your CD device dance to the tune of
+ Mozart's 40th Symphony (there is one like that, right?).
+
+ o Can I...?
+
+ Yes, you can. This is free software (as in freedom, free speech),
+ and you might do whatever you wish with it, provided you do not
+ limit freedom of others (GPL).
+
+ I'm considering licensing this under LGPL, but I *do* want
+ *every* PHP-gettext user to contribute and respect ideas of free
+ software, so don't count on it happening anytime soon.
+
+ I'm sorry that I'm taking away your freedom of taking others'
+ freedom away, but I believe that's neglible as compared to what
+ freedoms you could take away. ;-)
+
+ Uhm, whatever.
