Nothing shell-like in these systems. Everything is being coded to just about 100% accuracy (according to the documentation we have) based on flow charts and schematics. It's not a case of "if switch is turned on, then illuminate this light bulb." It's "if switch is turned on, activate relay, close circuit, etc, etc, etc and turn on light bulb" (My version of code). Too early to mention any kind of feature list, but it's very safe to say that people will be very happy at what we have included.
