--{{{ Awesome Invaders by Gregor "farhaven" Best
-- The ultra-cool retro graphics are done by Andrei "Garoth" Thorp.
--
-- Use Left and Right to control motion, Space to fire, q quits the game,
-- s creates a screenshot in ~/.cache/awesome (needs ImageMagick).
--
-- Maybe there are some huge memory leaks here and there, if you notice one,
-- message me.
--
-- Anyway, have fun :)
--
-- Start this by adding
-- require("invaders")
-- to the top of your rc.lua and adding
-- invaders.run()
-- to the bottom of rc.lua or as a keybinding
