/**
 * Widget that places a powered-by-Apache message on the page.
 *
 * 

 * The variable it resolves is "$W{PoweredByApache}".
 *
 * 

 * It produces a simple Apache icon floating on the right.
 * Typically it's used in the footer of the page, as shown below in the RootResources from the examples:
 *
 * 

 * 	@RestResource(
 * 		path="/",
 * 		title="Root resources",
 * 		description="Example of a router resource page.",
 * 		widgets={
 * 			PoweredByApache.class
 * 		},
 * 		htmldoc=@HtmlDoc(
 * 			footer="$W{PoweredByApache}"
 * 		)
 * 
 *
 * 

 * It renders the following image:
