This bot is meant to help identify issues with a CPython pull request.
What the bot identifies
bugs.python.org issue numbers in the title
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.
Aside: where does the name come from?
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.
