This is most awesome thing, I wish more projects would use linking exception!

Just in case someone will reuse code on server side; why not to use AGPL instead of GPL ?

What's strange is the README says this, but I don't see a linking exception in the actual license.

It's per source code file, and it is not explicitly defined what is and what is not an engine API calls.
