	Introduction
		The =Uize.Widget.Page.xDeferredLinks= module extends the =Uize.Widget.Page= base class by adding functionality for defer wiring links on the page.

		*DEVELOPERS:* `Ben Ilegbodu`, original code contributed by `Zazzle Inc.`

		Instead of relying on search engines or scrapers to adhere to rel="nofollow", you can include link tags in the page with dummy =href= attributes (such as ="javascript://"=), and set the =href= in the JavaScript.
