This script scans files for lines that look like either ui.config
usage or config variable documentation. It then ensures:
- ui.config calls for each option agree on types and defaults
- every option appears to be mentioned in documentation
It doesn't complain about devel/experimental options and allows
marking options that are not intended to be public.
Since we haven't been able to come up with a good scheme for
documenting config options at point of use, this will help close the
loop of making sure all options that should be documented are.
