"""The parsers are developed, debugged, and refactored in this file.

When they mature, I refactor them into standalone modules under the `parser`
directory.

Eventually, the entire parse step will mature and be abstracted into a
single function call, which will be appropriate to call in `main.py`.

If you can see this file, then I'm not done yet.
