YUI 2.x is deprecated. This code is preserved here as a legacy archive for anypoor soul who needs to work with it. Please use YUI 3.x (http://www.yuilibrary.com).* Documentation:http://yui.github.io/yui2/* License:http://yuilibrary.com/license/* Latest Stable Release:http://yui.github.io/yui2/* Discuss:http://yuilibrary.com/forum/* Contributor Info:http://yuilibrary.com/contribute/The source tree for YUI 2.x includes the following directories:* api: Generated API docs for the entire library in HTML format.  These     documents are build using YUI Doc from the contents of the src     directory.* build: Generated/built YUI files.  The built files are generated from     the contents of the src directory.  Files are provided in full,     commented form (suitable for debugging) and in minified form     (suitable for deployment and use).* sandbox: The sandbox directory contains works-in-progress, including     unreleased future components, as well as experimental and/or     demonstration code created by library authors.* src: This directory contains the source code (JavaScript, CSS, image     assets, ActionScript files) for the library. src also contains     all module documentation, tests and examples. The     src/common directory contains documentation, tests and examples     that are not for a specific YUI component. All modifications to     the library and its documentation should take place in this     directory.     The src directory also contains build.xml files, which can be     used to build individual modules using the also-deprecated YUI     Builder tool (http://github.com/yui/builder). The README in the     componentbuild directory of the builder project     covers installation and use of the build tool.
