+The YUI global namespace object. This is the constructor for all YUI instances.
+
+This is a self-instantiable factory function, meaning you don't need to precede
+it with the `new` operator. You can invoke it directly like this:
+
+ YUI().use('*', function (Y) {
+ // Y is a new YUI instance.
+ });
+
+But it also works like this:
+
+ var Y = YUI();
+
+The `YUI` constructor accepts an optional config object, like this:
+
+ YUI({
+ debug: true,
+ combine: false
+ }).use('node', function (Y) {
+ // Y.Node is ready to use.
+ });
+
+See the API docs for the <a href="config.html">Config</a> class for the complete
+list of supported configuration properties accepted by the YUI constuctor.
+
+If a global `YUI` object is already defined, the existing YUI object will not be
+overwritten, to ensure that defined namespaces are preserved.
+
+Each YUI instance has full custom event support, but only if the event system is
+available.
+
+@class YUI
+@uses EventTarget
+@constructor
+@global
+@param {Object} [config]* Zero or more optional configuration objects. Config

+ Utility method for safely creating namespaces if they don't already exist.
+ May be called statically on the YUI global object or as a method on a YUI
+ instance.
+
+ When called statically, a namespace will be created on the YUI global
+ object:
+
+ // Create `YUI.your.namespace.here` as nested objects, preserving any
+ // objects that already exist instead of overwriting them.
+ YUI.namespace('your.namespace.here');
+
+ When called as a method on a YUI instance, a namespace will be created on
+ that instance:
+
+ // Creates `Y.property.package`.
+ Y.namespace('property.package');
+
+ Dots in the input string cause `namespace` to create nested objects for each
+ token. If any part of the requested namespace already exists, the current
+ object will be left in place and will not be overwritten. This allows
+ multiple calls to `namespace` to preserve existing namespaced properties.
+
+ If the first token in the namespace string is "YAHOO", that token is
+ discarded. This is legacy behavior for backwards compatibility with YUI 2.
+
+ Be careful with namespace tokens. Reserved words may work in some browsers
+ and not others. For instance, the following will fail in some browsers
+ because the supported version of JavaScript reserves the word "long":
+
+ Y.namespace('really.long.nested.namespace');
+
+ Note: If you pass multiple arguments to create multiple namespaces, only the
+ last one created is returned from this function.
