Lua doesn't have preprocessor statements. Including files is done at runtime!
You don't need to create a module or anything (though you can!). To include another file (for example "blargh.lua"), just do this:
require "blargh"
If you actually want to package together files, you can create a folder named like "mypackage", and put a Lua file named "init.lua" inside, which will do the loading of all the crap. Then you just require the entire package like this (which will load the init.lua in that folder)
require "mypackage"
If for some reason you need to change the way files are included, check out
package.path.
Stupid example, but say you want to include files that are like AwesomeNachos, AwesomeHats, AwesomePants with a simple require like this:
require "Nachos"
require "Hats"
require "Pants"
To allow this, you can modify the load path.
package.path = package.path .. ";Awesome?.lua"
So you are able to add rules which will change how files are included. Each entry is separated by ; semicolon. Question marks ? represent "wildcards", which are whatever the text provided to
require happens to be.
Though this is really more useful for requiring files in subfolders or something, but same rules.
