Important update: The latest version of this workflow uses a new (unofficial) version of blueutil which is a copy of the original source code, only rewritten and compiled (by me) for the latest OS X, that is for the OS X 10.10 beta, too. I am a little worried that by having it compiled for the beta, it won't work for 10.9 and lower but I hope there won't be a problem. If there is, please tell me and I will release a version with the original blueutil. Using: custom version of blueutil (http://www.frederikseiffert.de/blueutil/)
