+	 * This function returns an HTML link to the given target.  It serves a few
+	 * purposes:
+	 *   1) If $target is a Title, the correct URL to link to will be figured
+	 *      out automatically.
+	 *   2) It automatically adds the usual classes for various types of link
+	 *      targets: "new" for red links, "stub" for short articles, etc.
+	 *   3) It escapes all attribute values safely so there's no risk of XSS.
+	 *   4) It provides a default tooltip if the target is a Title (the page
+	 *      name of the target).
+	 * link() replaces the old functions in the makeLink() family.
+	 *
+	 * @param $target        Title  Can currently only be a Title, but this may
+	 *   change to support Images, literal URLs, etc.
+	 * @param $text          string The HTML contents of the <a> element, i.e.,
+	 *   the link text.  This is raw HTML and will not be escaped.  If null,
+	 *   defaults to the prefixed text of the Title; or if the Title is just a
+	 *   fragment, the contents of the fragment.
+	 * @param $customAttribs array  A key => value array of extra HTML attri-
+	 *   butes, such as title and class.  (href is ignored.)  Classes will be
+	 *   merged with the default classes, while other attributes will replace
+	 *   default attributes.  All passed attribute values will be HTML-escaped.
+	 *   A false attribute value means to suppress that attribute.
+	 * @param $query         array  The query string to append to the URL
+	 *   you're linking to, in key => value array form.  Query keys and values
+	 *   will be URL-encoded.
+	 * @param $options       mixed  String or array of strings:
+	 *     'known': Page is known to exist, so don't check if it does.
+	 *     'broken': Page is known not to exist, so don't check if it does.
+	 *     'noclasses': Don't add any classes automatically (includes "new",
+	 *       "stub", "mw-redirect", "extiw").  Only use the class attribute
+	 *       provided, if any, so you get a simple blue link with no funny i-
+	 *       cons.
+	 *     'forcearticlepath': Use the article path always, even with a querystring.
+	 *       Has compatibility issues on some setups, so avoid wherever possible.
