support for (or documentation for) adding directory structure

[hagoss01]

perhaps I don't have a good understanding of how this all works currently, however, it seems like it would be useful to be able to add a directory to be included with the built project.

My specific use case is creating a data directory. I could create this under static, I suppose, but I thought it belonged elsewhere. This data directory will be ultimately populated by an external process (lambda) to provide some content for some tables. I could throw it under the static directory but I was attempting to organize things differently and I didn't know if that was possible. I'm even willing to hack it if anyone has pointers on where to start looking for what controls this behavior. Thanks
