+ * Ext.ClassManager manages all classes and handles mapping from string class name to
+ * actual class objects throughout the whole framework. It is not generally accessed directly, rather through
+ * these convenient shorthands:
+ *
+ * - {@link Ext#define Ext.define}
+ * - {@link Ext#create Ext.create}
+ * - {@link Ext#widget Ext.widget}
+ * - {@link Ext#getClass Ext.getClass}
+ * - {@link Ext#getClassName Ext.getClassName}
+ *
+ * # Basic syntax:
+ *
+ * Ext.define(className, properties);
+ *
+ * in which `properties` is an object represent a collection of properties that apply to the class. See
+ * {@link Ext.ClassManager#create} for more detailed instructions.
+ *
+ * Ext.define('Person', {
+ * name: 'Unknown',
+ *
+ * constructor: function(name) {
+ * if (name) {
+ * this.name = name;
+ * }
+ *
+ * return this;
+ * },
+ *
+ * eat: function(foodType) {
+ * alert("I'm eating: " + foodType);
+ *
+ * return this;
+ * }
+ * });
+ *
+ * var aaron = new Person("Aaron");
+ * aaron.eat("Sandwich"); // alert("I'm eating: Sandwich");
+ *
+ * Ext.Class has a powerful set of extensible {@link Ext.Class#registerPreprocessor pre-processors} which takes care of
+ * everything related to class creation, including but not limited to inheritance, mixins, configuration, statics, etc.
+ *
+ * # Inheritance:
+ *
+ * Ext.define('Developer', {
+ * extend: 'Person',
+ *
+ * constructor: function(name, isGeek) {
+ * this.isGeek = isGeek;
+ *
+ * // Apply a method from the parent class' prototype
+ * this.callParent([name]);
+ *
+ * return this;
+ *
+ * },
+ *
+ * code: function(language) {
+ * alert("I'm coding in: " + language);
+ *
+ * this.eat("Bugs");
+ *
+ * return this;
+ * }
+ * });
+ *
+ * var jacky = new Developer("Jacky", true);
+ * jacky.code("JavaScript"); // alert("I'm coding in: JavaScript");
+ * // alert("I'm eating: Bugs");
+ *
+ * See {@link Ext.Base#callParent} for more details on calling superclass' methods
