How does routing work?
A. Emma routing allows a convenient shorthand for defining simple connections between fields. In the same way you can use the DO syntax to place a function on a field, you can use the keywords TO and FROM to specify a a destination (in the case of TO) or source (in the case of FROM) for an event. You can also use a separate ROUTE statement, where you specify both the source and destination of the event. Routing in Emma is handled using Lua function calls.
