libsystem is the default system library for Phoenix. It provides convenient library functions for interacting with the kernel and other useful routines. libsystem attempts to implement all of the functionality of CraftOS in a new API that's cleaner and more in-line with Phoenix's design.
Simply copy all Lua files into /lib/system, or copy a built libsystem.a to /lib.
Load any module in this library with local module = require "system.module". See the documentation for more information on how to use each module.
