-- Hi, I am some lua code
require http://www.synthetic-reality.com/drone/story_platform

-- The line above basically fetched the text of
-- a lua library from a web resource, then loaded
-- it into this lua context such that the 
-- following lua code can act as if those 
-- libraries are available (because they will
-- have created one or more global objects
-- you can invoke methods on, like the game
-- object you always have.)

   -- the player has finished task (#14)
