---{{{ 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
