<!--
Note to customizers: the body of the webrev is IDed as SUNWwebrev
to allow easy overriding by users of webrev via the userContent.css
mechanism available in some browsers.
For example, to have all "removed" information be red instead of
brown, set a rule in your userContent.css file like:
body#SUNWwebrev span.removed { color: red ! important; }
-->
