init.lua

---A combination of extensions to the Lua standard libraries and other useful utilities for libraries I use.
---@module extensions

-- This initialization module is designed for use in the Luvit environment.
-- It *will* not work elsewhere, however you can still copy the individual
-- extensions from the `libs` directory and they should work.
-- Luvit uses Luajit 2.1, but `table.new` is not included in the stdlib by default
