-- Class: Gamepad

-- This represents a single gamepad connected to the user's computer. This offers the

-- usual functions to check on the status of buttons; you can also inspect other

-- controls, like analog joysticks, by checking properties like <axes> and <hats>.

-- (Incidentally, a hat is used for things like a digital control pad.)
