+/**
+ * DibiObject is the ultimate ancestor of all instantiable classes.
+ *
+ * DibiObject is copy of Nette\Object from Nette Framework (https://nette.org).
+ *
+ * It defines some handful methods and enhances object core of PHP:
+ *   - access to undeclared members throws exceptions
+ *   - support for conventional properties with getters and setters
+ *   - support for event raising functionality
+ *   - ability to add new methods to class (extension methods)
+ *
+ * Properties is a syntactic sugar which allows access public getter and setter
+ * methods as normal object variables. A property is defined by a getter method
+ * and optional setter method (no setter method means read-only property).
+ * <code>
+ * $val = $obj->label;     // equivalent to $val = $obj->getLabel();
+ * $obj->label = 'Nette';  // equivalent to $obj->setLabel('Nette');
+ * </code>
+ * Property names are case-sensitive, and they are written in the camelCaps
+ * or PascalCaps.
+ *
+ * Event functionality is provided by declaration of property named 'on{Something}'
+ * Multiple handlers are allowed.
+ * <code>
+ * public $onClick;                // declaration in class
+ * $this->onClick[] = 'callback';  // attaching event handler
+ * if (!empty($this->onClick)) ... // are there any handlers?
+ * $this->onClick($sender, $arg);  // raises the event with arguments
+ * </code>
+ *
+ * Adding method to class (i.e. to all instances) works similar to JavaScript
+ * prototype property. The syntax for adding a new method is:
+ * <code>
+ * MyClass::extensionMethod('newMethod', function (MyClass $obj, $arg, ...) { ... });
+ * $obj = new MyClass;
+ * $obj->newMethod($x);

-Introduction
-------------
-
 Database access functions in PHP are not standardised. This library
 hides the differences between them, and above all, it gives you a very handy interface.
 
-If you like Dibi, **[please make a donation now](https://nette.org/make-donation?to=dibi)**. Thank you!
+The best way to install Dibi is to use a [Composer](https://getcomposer.org/download):
+
+    php composer.phar require dibi/dibi
+
+Or you can download the latest package from http://dibiphp.com. In this
+package is also `Dibi.minified`, shrinked single-file version of whole Dibi,
+useful when you don't want to modify the library, but just use it.
+
+Dibi requires PHP 5.2.0 or later. It has been tested with PHP 5.5 too.
 
 
-Installation
-------------
-
-The recommended way to install Dibi is via Composer (alternatively you can [download package](https://github.com/dg/dibi/releases)):
-
-```bash
-composer require dibi/dibi
-```
-
-The Dibi 3.x requires PHP version 5.4.4 and supports PHP up to 7.2.
-
-
-Usage
