Contrast and Compare CPF and Xproc or: CPF for Mortals

This is your chance to learn, teach and eat pizza, while we submit CPF and Xproc to the question. I am looking for some depth here, guys, how and why it works the way it does -- but yes, we can have tips and tricks for dessert.

I have currently set the date for 9/13/2012, to put a stake into the ground. Why 9/13? Well, it isn't 9/11. And it is 13. And it is a Thursday, which is towards the end of the week not a Friday night.

But the date can be adjusted if some compelling reason to do so presents itself, such as a visit from a member of the Happy Few or other Olympian denizen -- present company included of course.
