Why khatru?

If you want to craft a relay that isn't completely dumb, but it's supposed to

• have custom own policies for accepting events;
• handle requests for stored events using data from multiple sources;
• require users to authenticate for some operations and not for others;
• and other stuff.

khatru provides a simple framework for creating your custom relay without having to reimplement it all from scratch or hack into other relay codebases.
