 Many CAPTCHA implementations have been implemented lately to improve past solutions to make it difficult for robots pretend to be real human users and commit many types of site abuses.

This package provides another kind of CAPTCHA implementation. It asks questions that are easy to answer a real human being, but are hard or even impossible to answer for robots that are not trained.
