> by the way - I can't get appledocs to install. brew install appledoc fails as well as compiling the xcode project. the xcode project tries to convert to ARC, but fails because of an NSObject embedded inside of a struct within the project. Have you run into this? 

I don't think so, but I'm not sure what you mean. You start by talking about brew installing appledoc and end with something odd about ARC and NSObjects inside structs...
