No idea what this package does

I am doing cleanup for fedora-packages project and I can not get what this project does. Description is too high level for my level, there are no examples in README.md and documentation link shows Permission denied page.

crank is the routing library of TurboGears, it implements the object dispatch routing system ( https://turbogears.readthedocs.io/en/latest/turbogears/objectdispatch.html?highlight=object%20dispatch ).

I'm not aware of projects using it outside of TurboGears itself, there was a plan to document it as a standalone library to allow third parties usage, but in the end no one ever invested the effort to do so.

routing is a clear term, thanks. I now recall there was a trend in MVC frameworks to have those dynamic rules to map URLs to object methods. However ObjectDispatching is still unclear, by the name it is not the request that is dispatched, but some object. Too abstract for beginners - not enough examples. Documentation says it is possible to "making possible for example to generate all the urls knowing where they are mounted", but doesn't show how.

Does that object traversal occurs on every request? Because that looks like a very costly operation for every request.
