/*
 * I am a set of JavaScript functions for sending bookmarks using an AJAX-style in-place form.
 * Rather than using a normal form submission, the contents of the bookmark panel div
 * are replaced by server-side generated HTML fragments when a form button is clicked.
 * 
 * I use Prototype, a JavaScript framework with some AJAX helper functions.
 * See http://prototype.conio.net/ for the code and
 * http://www.sergiopereira.com/articles/prototype.js.html for documentation.
