+[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.
