// This file tests topic inclusions and inheritance:
//
// includes: this means that the topic "includes" the triggers present
//           in another topic. Matching triggers in the source and included
//           topic are possible, and the *reply* in the source topic overrides
//           the reply in the included topic.
// inherits: all triggers in the source topic have higher matching priority than
//           all triggers in the inherited topic. So if the source topic has a
//           trigger of simply *, it means NO triggers can possibly match on the
//           inherited topic, because '*' goes higher in the match list.

// Aliases
! sub n = north
! sub w = west
! sub s = south

	// All of these triggers have higher matching priority than all other
	// triggers from the other topics, because this topic inherits a topic. So
	// the matching list looks like this:
	//   exits
	//   north
	//   look
	//   (combined triggers from earth & global)
	// Because our "north" is near the top of the match list, ours always gets
	// called. But if we try saying "south", we end up matching the "south" from
	// the global topic.

// Topic "puzzle" is a placeholder that sets all the directions to return
// us to the crash site. puzzle inherits mars so that puzzle's directions
// will override the directions of mars. All the steps of the puzzle then
// "include" puzzle, and override only one direction. e.g. since "west"
// exists in puzzle1, the response from puzzle1 is given, but if you're
// in puzzle1 and type "north"... north was included from "puzzle", but
// puzzle1 doesn't have a reply, so the reply from "puzzle" is given.
