This plugin shows how to add links to the CMS header with the following
- Add a link to Google _before_ all of the existing links.
- Add a link to Yahoo _after_ all of the existing links.
- Remove the "license" link from the existing links.
You can modify this plugin to easily add your own links or remove the links
you don't want or even just change the HTML that is displayed in the header
section of the CMS.
