+@acronym{ECS, Entity-Component-System} pattern, primarily focused on speed and
+interactive development.
+
+ECS is an architectural data-oriented design pattern that allows for the
+effective processing of a large number of in-game objects while keeping the code
+and data separated.  This provides flexibility in the way that game objects are
+built at runtime.")
