Qualifications

There are a ton of great Python projects out there, but what makes an application "Awesome™"? Please check that all of the following criteria apply:

• [ ] Free software with an online source repository.
• [ ] Using Python for a considerable part of their functionality.
• [ ] Well-known, or at least prominently used in an identifiable niche.
• [ ] Maintained or otherwise demonstrably still functional on relevant platforms.
• [ ] An application, not a library or framework.
