+_An exemple of torchbearer in action,
+demonstrating both pathfinding and field of view_
+
+[torchbearer] by [@redwarp] is a library that provides a set of tools
+to find your path in a grid based dungeon. Specifically,
+it provide a quick implementation of pathfinding and field of view algorithm.
+
+The 0.6.x version rewrites the field of view algorithm to cast vision rays
+in a bresenham circle around the point of origin.
+This change from its [original implementation][torchbearer-orig] makes it faster
+as it removes the needs for error correction.
