Middleman is actually a really great piece of software. I've used it on multiple projects, and it's really great for what it does.<p>When all you have to do is hand a set of static files off to the client, Middleman allows you to use your favorite technologies like Sass, and comes combined with LiveReload (which is a nice time-saver).<p>It's also very Sinatra-esque, which I greatly approve of.
