I like the idea of a build batch. However, something in that file, and/or the readme, just mentioning some of the build tech being used would be great too. Some people will just want to build and get through their contribution. However, I had only subconsciously heard of Rake before my first contribution. Having to dig a little bit, for me, turned me on to Rake as a tool that I now use for all my new projects (and some old project builds that made me want to kill a unicorn).
So, for those that want to dig around a little, they could very well learn about something not directly related to Fubu that opens up a whole new world. Not only that, but nobody wants to see a dead unicorn.
