Is there a config file for [Uncrustify](http://uncrustify.sourceforge.net/) that will format Objective-C per [Google's Objective-C style guide](http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml)?

Example config files for Uncrustify [look a bit daunting](https://gist.github.com/841452) and I'm hoping that I won't need to build one from scratch...
