Previously I had created an Xcode plugin for Hudson to allow you to configure and invoke builds directly. Although this worked for some cases, there are a few projects where the build process is more complex or non-standard enough to force me back to scripting things manually. Rather than update the plugin to try and cope with every esoteric use case, I decided to flip things around and simple create a ruby-wrapper for Xcode. This allows me to take what i need and create custom Rakefiles to control the build process.
