#include_humanizing_javascript(url = "/abongo_mark_human", style = :prototype) ⇒ Object

This causes an AJAX post against the URL. That URL should call Abongo.human! This guarantees that anyone calling Abongo.human! is capable of at least minimal Javascript execution, and thus is (probably) not a robot.
