All code (excluding the build craft API, which is covered by the build craft liscence) is liscened under the WTFPL (Do What the Fuck You Want to Public License http://www.wtfpl.net/ ) Do what you want with it, as long as you smile while doing so. While it is not a requirement, it would be nice to know if it is being used and how, so send me hello to crazypants.mc at gmail.com.
