Other faction tech trees ingame?

Sorry probably a dumb noob question, but on the paper that came with the box that shows the roman tech tree it says "additional faction tech trees available ingame". Anyone know where they are?

When you play the faction, and enter the construction scroll, the uppermost left button (if memory serves) will show the tech tree. This was a welcome addition by CA.
