[jQuery] cluetip - how to override defaults?

[Brian J. Cohen]

If I just include the cluetip JS and CSS, I can activate cluetip
pretty easily, with its default settings, by setting class="cluetip"
on <a> tags.

I want to override those defaults. For example, I tried setting:

$(document).ready(function() {
     $("a.cluetip").cluetip({ activation: 'click' });
});


But the default behavior persists. Any help is greatly appreciated.
