...is a jQuery plugin that turns any element into a virtual browser window (or iframe),
and captures all link-clicks and form-submits and convert them into ajax-requests,
and then (manipulate and) insert the response document into the
virtualBrowser element (which is the semantic equivalient of a real browser's <body>).
For more details, read the documentation (stored as inline comments in the un-minified script file) and study the demo.
BTW Version 1.1 is the current version. The 1.0 folder is left in for posterity to support older scripts.
