a powerful alternative to 'make'
Prime Mover is a build tool, similar to 'make', but considerably more powerful and easier to use. Due to magic, it's written entirely in Lua but doesn't require a Lua interpreter to run --- simply distribute the single executable with your project and it'll run on any (Unix-like) platform.
