gale package

gale (Game Architecture & Logic Engine): a collection of reusable building blocks (state machines, input handling, physics, networking, UI, AI, and more) to speed up building 2D games with pygame. Each submodule (gale.state, gale.input_handler, gale.physics, gale.net, gale.ui, gale.ai, …) is independent — import only the ones a given game actually needs.
