A basic problem is that posts need to know canonical URLs, but canonical
URLs are generated after posts. To solve this, we look at the URLs first,
and only then do we render the templates and write out the actual data.
Steps:
* Collect URL information
This is done during the pipeline/query phase. To be precise, we collect:
- what URLs get rendered with what templates, data.
- what URLs are canonical for what names.
