Marshall, thanks for setting this up. Would you mind if we turn this into a general sandbox documentation project? Now that you have done the initial work of creating a docbook build, we might want to add documentation about other sandbox projects, not just the CAS Editor.
A minor nit: all other projects in the sandbox use camel case project names. While that's not the way I would have set it up either, that's how it is now. It would be nice if we could have consistency within the sandbox. --Thilo
