This I feel is a real problem for the embedded API as it is.
The above is documented in the source, but not in the header.
Source comment documentation is fine for the source authors but it leaves consumers out in the cold.
The long and the short of it is that you really need to have the Mono embedded source to hand at all times even if you don’t build you own Mono.
