; _G : the table with the ''global environment'', i.e. all global variables, including itself and the other variables listed here
; _VERSION : string with the name of the interpreter and the major and minor version, e.g. "Lua 5.2"
To list all global variables:
<lang lua>for n in pairs(_G) do print(n) end</lang>
The list will include built-in global functions, whose availability depends on the implementation and compile time configuration.
