View source for Library extension

A '''library extension''' (also known as a '''library module''') is some code designed to be reused in a number of different games.  Most [[authoring system]]s come with a standard [[library]] of code that provides the basic [[parser]] system and world model.  Other authors then offer library extensions to provide other specific functionality: for instance, better [[NPC]] handling or more sophisticated [[simulation]] of some kind.  

[[Author]]s can then choose to use these modules to add functionality to their games without having to reinvent the wheel.
