Library module files are supposed to return a true value. Having a one at the end accomplishes this. I don't recall the exact reason but I think it's because, underneath all of the fancy importing and namespace magic that 'use' does, there's a 'do FILE' deep down, and it returns the last value evaluated in a file, and you will always want that to be true.
