Description

A collection of all my ComputerCraft programs and the APIs they use. This is mostly just to get them the fuck off of pastebin, and also to ensure that API owners don't change things to break my precious programs...!

Installation

Copy one of these commands into your ComputerCraft terminal:

wget:wget https://raw.githubusercontent.com/LDDestroier/CC/master/roterm.lua roterm
Archive:wget https://cc.shobie.xyz/cc/get/gh-LDDestroier-CC-roterm roterm
Quick Install: wget https://cc.shobie.xyz/cc/get/gh-LDDestroier-CC-roterm roterm

Usage

Run: roterm
