Comparison of configuration file languages

We need to PEPify a static format for writing down bootstrap information in Python source trees. The initial target is a list of PEP 508 package requirement strings. It's possible that in the future we might want to add more features like a build system backend specification (as in PEPs 516, 517), or an extension namespace feature to allow third-party developer tools (flit, pytest, coverage, flake8, etc.) to consolidate their configuration in this file in a systematic

The company itself is [transparent about their operations][trans] and [generous with their knowledge sharing][blog]. To me, this says they understand their customers well. I've never had reliability problems and everything about the outfit exudes a sense of simple, quick, solid quality. The service has even saved the day on a couple of occasions where I've lost files.

Safe to say, I'm a happy customer. If you're not already using Backblaze, [I highly recommend you do][recommend].
