 Bumblebee works by injecting a custom JavaScript program that intercepts
 client-side events and sends them to Bumblebee for analysis. In addition to
 front-end events, Bumblebee also captures internal browser events, which it
 then interprets to generate code in real time. Note that we developed Bumblebee

 Before settling on a desktop application, we contemplated designing Bumblebee
 as a browser extension. We chose the desktop app because extensions don't offer
 the deep, event-based control we needed. Besides, the company's security
 policy, which prohibited browser extensions, would have complicated the
