			my_object = {}; --All lua modules on wiki must define a global variable
	print("Hello World")
			--that will hold their externally accessible functions.
			--Such global variables can have whatever name you want
			--and may also return various data as well as functions.

			my_object.hello = function( frame ) --Add a function to "my_object".
			--Such functions are callable via #invoke.
			--"frame" contains data that Wikipedia
			--will send this function when it runs.

			return "Hello World!" --Do nothing but return "Hello World!"

			end -- end of function "hello"

			return my_object --All modules end by returning the global variable to Wikipedia.

			-- Now we can use this module by calling {{#invoke: Sandbox/sameboat \| hello }}.
			-- Note that the first part of the invoke is the name of the Module's wikipage,
			-- and the second part is the name of one of the functions attached to the
			-- global variable that you returned.

			-- The "print" function is not allowed in Wikipedia. All output is accomplished
			-- via strings "returned" to Wikipedia.
