Finding where file is being run from?

I'm working in Lua (not ComputerCraft Lua or another variant) and I want to know how you can find where the current Lua script is being stored

I mean, something like this:

C:\Users\blergh\example.Lua

I want to be able to find that in the Lua script in example.Lua and be able to say; "That's where I'm running from."

I'm looking in the IO library and the 'LuaFileSystem' module, but I've not found anything that returns the directory of the currently executing script.

Here is a StackOverflow article I found on the matter… http://stackoverflow.com/questions/6032268/get-current-working-directory-in-lua
