xref: Add Links To Pages Automatically

xref: Add Links To Pages Automatically: "When included in a Web page, xref will examine the text of that page, looking for predefined key terms within it. When such a key term is found, the script automatically converts that term into a clickable link, with the link itself also going to a pre-defined URL (a page that further describes the term, or is somehow directly related to the term in question). A predefined title will also be applied to the term (which most modern browsers will display when the user hovers over the link), if so desired."
