Hi nijel,
Correct me if I'm wrong, but it looks like this project declares its licenses inside of Python docstrings instead of regular comment blocks.
We don't yet support Python docstrings. Our parser only looks in regular comment blocks for license information.
This also means that we are short-changing this project on its comment count, since we are counting all of the documentation as string constants, which we would consider code. Properly, docstrings should be counted as comments.
This is a known issue on our to-do list.
Thanks,
Robin
