If you’re like me, you probably have a “sandbox” somewhere, a place where you hack on whatever projects you’re working on. Over time, the sandbox will get crufty and cluttered with bits and pieces of ideas, toolchain elements, code modules you aren’t using, and other stuff you don’t need. When you finish something, this can complicate your deployment, because you may be unsure of the actual dependencies of your project—you’ve had some tool in your sandbox for so long that you forget it must be installed.
