This directory contains core scriptcraft files and modules.

• plugin.js - A module which provides support for persistent plugins (plugins which need to save state)
• require.js - The require() function implementation. See [Node.js modules] documentation.
• scriptcraft.js - The core scriptcraft code.
• events.js - Event handling module for use by plugin/module developers.

When require('modulename') is called, if a file in the current working directory called 'modulename' is not found then the lib folder is the first location that require() looks for modules.
