local p = {}; --All Lua modules on Wikipedia must begin by defining a variable
--that will hold their externally accessible functions.
--Such variables can have whatever name you want and may
--also contain various data as well as functions.
p.hello = function( frame ) --Add a function to "p".
--Such functions are callable in Wikipedia
--via the #invoke the command.
--"frame" will contain the data that Wikipedia
--sends this function when it runs.
-- 'Hello' is the name of your choice. The same name needs to be referred to when the module is used.
local str = "Hello World!" --Declare a local variable and set it equal to
--"Hello World!".
return str --This tells us to quit this function and send the information in
--"str" back to Wikipedia.
end -- end of the function "hello"
