+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser 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
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+php: PHP CLI interface.
+phpdoc: phpDocumentor.
+phpunit: PHPUnit testing framework.
+PHK_Creator.phk: this is file which you download from http://phk.tekwire.net/.
+
+To build PHAR package you will need PECL PHAR extension installed.
+
+Possible targets:
+
+all: default one, runs all other targets (in order: clean, check, documentation, pdf, online, test, package, manual, phk, phar).
+clean: deletes documentation.
+check: checks syntax of all PHP files.
+documentation: generates HTML documentation.
+pdf: generates PDF documentation.
+online: OTServ-AAC website documentation template used.
+test: runs test suite.
+package: creates pot.tar.gz file for distribution purposes.
+manual: creates documentation.tar.gz file for distribution purposes.
+phk: creates POT.phk distribution package.

+Zero rule: We use Unicode (UTF-8).
+
+    Of course we should handle input encoding respectively, but output and internal data/code are all written in UTF-8.
+
+I. Coding rules to be followed:
+
+[1] Never ever use global!
+
+    It's just the worst thing you can do in PHP scripts.
+
+[2] Avoid using define - use class constants.
+
+    To group code better, to allow classes __autoload() handling.
+
+[3] Use !isset() instead of is_null().
+
+    That has exacly same effect and we should follow the most simplies methods. Just to make code cleaner (however remember that isset() is a PHP langauge structure and has it's limitations!).
+
+[4] Don't use functions - use class methods (except Compat package).
+
+    This will allow __autoload() handling for all routines as they will be members of classes.
+
+[5] Use 4 spaces as tabulation.
+
+    Tabulator character can be differently displayed and generaly four spaces makes code more readable.
+
+[6] Always use brackets for blocks and leave them in separated lines in same nesting level that block instruction:
+
+    if(condition)
+    {
+        for($i = 0; $i < $j; $i++)
+        {
+            statement;
+        }
+    }
+
+[7] Use single quotes insead of double ones.
+
+    ' are, in standard way, faster then " and it keeps code cleaner if you simply concat everything rather then inserting something like placeholders into string.
+
+[8] Use spaces between parenthess and operators (except object member accessing operator):
+
+    $foo = $lol . $rotfl;
+    $foo .= $bar;
+    $obj = new Class( substr( str_replace( implode('.', $array), ',', '.'), 2) );
+    echo $obj->field;
+    echo $obj->method( rand() );
+    echo $obj->method($value);
+
+[9] Use <?php opening tag.
+
+    It is the most reliable and standard way for starting PHP code.
+
+[10] Use isset(array[offset]) instead of array_key_exists().
+
+    It saves alot of resources (relatively).
+
+II. File naming:
+
+[1] Use lowercase names for directories.
+
+[2] Use fiels and directories in code in case-sensitive way.
+
+    Remember that probably this code will be mostly run on non-Windows platforms.
+
+[3] Use existing directories structure.
+
+    Put classes into classes directory, tutorials into tutorials directory etc.
