Hi, I've been working on a (very simple) module to create a "capabilities" endpoint, where a Sling instance can let HTTP clients know about its version levels, presence or absence of certain services etc.
It's at https://github.com/apache/sling-whiteboard/tree/master/capabilities and if no one is opposed I'll move it to its own module and make a first release later this week. Feedback is welcome. -Bertrand
