Is there any documentation on how to run RegCM4 with the slab ocean model option?

I found minimal discussion in the gforge documents (e.g. user's guide) and a brief discussion in the following article.

Is the RegCM4-slab ocean model running without any issues and is it straightforward to use?

Thanks, Michael
