This bot is meant to help identify issues with a CPython pull request.
If no b.p.o issue number is found the status fails and the "Details" link points to the relevant section of the devguide. If an issue number is found then the "Details" link points to the issue itself, making it easier to navigate from PR to issue.
Since this bot is about identifying pull requests that need changes, it seemed fitting to name it after Sir Bedevere who knew how to identify a witch.
