--[[
    Need Mac OSX and LuaJIT.
    LuaJIT can be installed from homebrew.

    download aite: https://github.com/rweichler/aite
    cd into this directory and run this command:
    /PATH/TO/AITE/main.lua

    if this errored at you in any way, email me at rweichler@gmail.com so i can fix it.

    OPTIONAL:
        install aite permanently by running this command:
        ln -s /PATH/TO/AITE/main.lua /usr/local/bin/aite

        now, instead of all those annoying steps, you'd just run this command:
        aite
