Where are the modules installed using luarocks

I am trying to require a module I downloaded using luarocks using ``` require "lualogging" ``` but lua (and I!) cannot find where this module was downloaded to. Here is what I did I have used apt-get to install luarocks, and then I ran ``` sudo luarocks install lualogging ``` I then ran ``` luarocks list ``` and received the following output ``` Installed rocks: lualogging 1.3.0-1 (installed) - /usr/local/lib/luarocks/rocks luasocket 3.0rc1-1 (installed) - /usr/local/lib/luarocks/rocks ``` Natural this led me to believe that lualogging was located in /usr/local/lib/luarocks/rocks, but running this command ``` find /usr/local/lib/luarocks/rocks "lualogging.lua" ``` returned nothing. What am I doing wrong here? This may be related, but I cannot find what my LUA_PATH environment variable is so it may be that it was never set? I'd like to be able to run require "lualogging" from any file regardless of where it is located in the filesystem, and then log to my heart's content. But I can't even find where lualogging.lua exists...
